employee or other third party intend to use the Licensed Materials. A separate license under a separate
License Agreement is also required if You wish to use a Client license (as described below).
•Single User, Multiple Network Device. Under the terms of this license type, the license granted to You by
Extreme authorizes You to use the Licensed Materials with a defined amount of Network Devices as defined
in the Ordering Documentation.
•Client. Under the terms of the Client license, the license granted to You by Extreme will authorize You to
install the License Key for the Licensed Materials on your server and allow the specific number of Concurrent
Users as ordered by you and is set forth in Your Ordering Documentation. A separate license is required for
each additional Concurrent User.
•Standalone. Software or other Licensed Materials licensed to You for use independent of any Network
Device.

5AUDIT RIGHTS
. You agree that Extreme may audit Your use of the Licensed Materials for compliance with these
terms and Your License Type at any time, upon reasonable notice. In the event that such audit reveals any use
of the Licensed Materials by You other than in full compliance with the license granted and the terms of this
Agreement, Extreme reserves the right to charge You for all reasonable expenses related to such audit in
addition to any other liabilities and overages applicable as a result of such non-compliance, including but not
limited to additional fees for Concurrent Users, excess capacity or usage over and above those specifically
granted to You. From time to time, the Licensed Materials may upload information about the Licensed Materials
and the associated usage to Extreme. This is to verify the Licensed Materials are being used in accordance with
a valid license and/or entitlement. By using the Licensed Materials, you consent to the transmission of this
information.
6 RESTRICTION AGAINST COPYING OR MODIFYING LICENSED MATERIALS. Except as expressly permitted in this
Agreement, You may not copy or otherwise reproduce the Licensed Materials. In no event does the limited
copying or reproduction permitted under this Agreement include the right to decompile, disassemble,
electronically transfer, or reverse engineer the Licensed Materials, including the Licensed Software, or to
translate the Licensed Materials into another computer language. The media embodying the Licensed Materials
may be copied by You, in whole or in part, into printed or machine readable form, in sufficient numbers only for
backup or archival purposes, or to replace a worn or defective copy. However, You agree not to have more than
two (2) copies of the Licensed Software in whole or in part, including the original media, in your possession for
said purposes without Extreme’ prior written consent, and in no event shall You operate more copies of the
Licensed Software than the specific licenses granted to You. You may not copy or reproduce the
documentation. You agree to maintain appropriate records of the location of the original media and all copies
of the Licensed Software, in whole or in part, made by You. Any portion of the Licensed Software included in
any such modular work shall be used only on a single computer for internal purposes and shall remain subject
to all the terms and conditions of this Agreement. You agree to include any copyright or other proprietary
notice set forth on the label of the media embodying the Licensed Software on any copy of the Licensed
Software in any form, in whole or in part, or on any modification of the Licensed Software or any such modular
work containing the Licensed Software or any part thereof.
7 TITLE AND PROPRIETARY RIGHTS

schematics, and such information may contain proprietary details and disclosures. All information and data so
acquired by You or your employees or agents under this Agreement or in contemplation hereof shall be and
shall remain Extreme’ exclusive property, and You shall use all commercially reasonable efforts to keep, and
have your employees and agents keep, any and all such information and data confidential, and shall not copy,
publish, or disclose it to others, without Extreme’ prior written approval, and shall return such information and
data to Extreme at its request. Nothing herein shall limit your use or dissemination of information not actually
derived from Extreme or of information which has been or subsequently is made public by Extreme, or a third
party having authority to do so
You agree not to deliver or otherwise make available the Licensed Materials or any part thereof, including
without limitation the object or source code (if provided) of the Licensed Software, to any party other than

Overview
Extreme Networks’ WiNG 5 operating system is the next generation in the evolution of WLAN
architectures. WiNG 5 OS is designed to scale efficiently from the smallest networks to large,
geographically dispersed deployments. The co-operative, distributed control plane innovation in the WiNG
5 architecture offers a software-defined networking (SDN)-ready operating system that can distribute
controller functionality to every Access Point in your network. Now, every Access Point is network aware,
providing the intelligence required to truly unleash optimal performance, all wireless LAN infrastructure can
work together to ensure every transmission is routed through the most efficient path, every time.
WiNG 5 brings you the resiliency of a standalone Access Point network without the vulnerability of a
centralized controller, with advancements that take performance, reliability, security, scalability and
manageability to a new level. The result? Maximum network uptime and security with minimal
management. And true seamless and dependable mobility for your users.
WiNG 5 advances the following technology:
Comprehensive Wi-Fi support - WiNG supports all Wi-Fi protocols, including 802.11a/b/g/n/ac, allowing you
to create a cost-effective migration plan based on the needs of your business.
Extraordinary scalability - With WiNG, you can build any size network, from a small WLAN network in a
single location to a large multi-site network that reaches all around the globe.
Extraordinary flexibility - No matter what type of infrastructure you deploy, WiNG 5 delivers intelligence to
all: standalone independent Access Points or adaptive Access Points that can be adopted by a controller
but can switch to independent mode; virtual controllers; physical controllers in branch offices, the network
operating center (NOC) or the cloud.
The power of distributed intelligence - WiNG distributes intelligence right to the network edge, empowering
every controller and Access Point with the intelligence needed to be network-aware, able to identify and
dynamically route traffic over the most efficient path available at that time.
Extraordinary network flexibility and site survivability - WiNG provides the best of both worlds: true
hierarchical management that delivers a new level of management simplicity and resiliency by enabling
controllers to adopt and manage other controllers and Access Points, while allowing adopted infrastructure
to also stand on its own.
Gap-free security - When it comes to security, there can be no compromises. WiNG’s comprehensive
security capabilities keep your network and your data safe, ensuring compliance with PCI, HIPAA and other
government and industry security regulations.
Connectivity for the largest indoor and outdoor spaces - In addition to enabling a robust indoor WLAN, our
patented MeshConnex™ technology enables the extension of Wi-Fi networks to the largest of outdoor
spaces from an expansive outdoor campus environment to an entire city.
Powerful centralized management - With WiNG you get complete control over every aspect of your WLAN.
This single powerful windowpane enables zero touch infrastructure deployment, rich analytics that can help
you recognize and correct brewing issues before they impact service quality and user connectivity, along
with centralized and remote troubleshooting and issue resolution of the entire network.
Application Visibility and Control - With WiNG you get visibility & control over Layer-7 applications with an
embedded DPI engine at the Access Point. Extreme Networks’ NSight (an add-on module to WiNG)
Overview
Wireless Controller and Service Platform System Reference Guide 1 - 2
provides real-time visibility and in-depth insight into every dimension of the network including layer-7
application visibility, client devices, device & OS types and users. At a glance the administrator can discern
the top applications by usage or by count at every level of the network from site level to Access Points and
clients. This is achieved by Deep Packet Inspection (DPI) of every flow of every user at the Access Point.
The embedded DPI engine in the WiNG OS can detect and identify thousands of applications real time and
report to NSight. In addition to detection, firewall and QOS policies can leverage the application context to
enforce policies.
1.1 Distributed Intelligence
WiNG 5 enables all WLAN infrastructure with the intelligence required to work together to determine the
most efficient path for every transmission. The need to route all traffic through a controller is eliminated,
along with the resulting congestion and latency, resulting in higher throughput and superior network
performance. Since all features are available at the access layer, they remain available even when the
controller is offline, for example, due to a WAN outage, ensuring site survivability and extraordinary
network resilience. In addition, you get unprecedented scalability, large networks can support as many as
10,000 nodes without impacting throughput or manageability, providing unprecedented scalability.
1.2 High Availability Networks
WiNG 5 enables the creation of highly reliable networks, with several levels of redundancy and failover
mechanisms to ensure continuous network service in case of outages. APs in remote sites coordinate with
each other to provide optimized routing and self-healing, delivering a superior quality of experience for
business critical applications. Even when WiNG 5 site survivable APs lose communication with the
controller, they continue to function, able to bridge traffic while still enforcing QoS and security policies,
including stateful inspection of Layer2 (locally bridged) or Layer 3 traffic.
1.3 Gap Free Security
When it comes to wireless security, one size does not fit all. A variety of solutions are required to meet the
varying needs and demands of different types of organizations. Regardless of the size of your WLAN or
your security requirements, our tiered approach to security allows you to deploy the features you need to
achieve the right level of security for your networks and your data. And where a hub-and-spoke
architecture can’t stop threats until they reach the controller inside your network, WiNG 5 distributes
security features to every access point, including those at the very edge of your network, creating an
around-the-clock constant network perimeter guard that prevents threats from entering your network for
unprecedented gap free security.
1.4 Outdoor Wireless and Mesh Networking
When you need to extend your wireless LAN to outdoor spaces, our patented MeshConnex technology
combines with comprehensive mesh networking features to enable you to create secure, high performance,
flexible and scalable mesh networks. With our mesh technology, you can cover virtually any area without
installing cabling, enabling the creation of cost-effective outdoor wireless networks that can provide
Overview
Wireless Controller and Service Platform System Reference Guide 1 - 3
coverage to enterprise workers in vast campus-style environments as well as public safety personnel in
patrol cars.
1.5 Network Services, Routing and Switching
WiNG 5 integrates network services like built-in DHCP server, AAA server and routing protocols like policy
based routing and OSPF, Layer 2 protocols like MSTP and Link Aggregation. Integration of services and
routing/ switching protocols eliminates the need for additional servers or other networking gear in small
offices thereby reducing Total Cost of Ownership (TCO). In large networks, where such services are
deployed on a dedicated server/ router at the NOC, this provides a backup solution for remote sites when
the WAN link to the NOC is temporarily lost. Integrating also provides the added benefit of coordination
across these services on failover from primary to standby, assisting a more meaningful behavior, rather
than when each fails over independently of the other for the same root cause.
1.6 Management, Deployment and Troubleshooting
WiNG’s comprehensive end-to-end management capabilities cover deployment through day-to-day
management. You get true zero-touch deployment for access points located anywhere in the world, the
simplicity of a single window into the entire network, plus the ability to remotely troubleshoot and resolve
issues. And since our management technology is manufacturer-agnostic, you can manage your Extreme
Networks WLAN infrastructure as well as any legacy equipment from other manufacturers, allowing you to
take advantage of our advanced WLAN infrastructure without requiring a costly rip and replace of your
existing WLAN.

The EX3500 series switch is a Gigabit Ethernet Layer 2 switch with either 24 or 48 10/100/1000-BASE-T ports, and
four small form factor pluggable (SFP) transceiver slots for fiber connectivity. Each 10/100/1000 Mbps port
supports both the IEEE 802.3af and IEEE 802.3at-2009 PoE standards. Each EX3500 series switch includes an
SNMP-based management agent, which provides both in-band and out-of-band access for management. An
EX3500 series switch utilizes an embedded HTTP Web agent and command line interface (CLI) somewhat
different from the WiNG operating system, while still enabling the EX3500 series switch to provide WiNG
controllers PoE and port management resources.
Going forward NX9600, NX9500, NX7500, NX5500 WiNG managed services platforms and WiNG VMs can
discover, adopt and partially manage EX3500 series Ethernet switches, as DHCP option 193 has been added to

Device Configuration
Managed devices can either be assigned unique configurations or have existing RF Domain or Profile
configurations modified (overridden) to support a requirement that dictates a device’s configuration be
customized from the configuration shared by its profiled peer devices.
When a device is initially managed by the controller or service platform, it requires several basic configuration
parameters be set (system name, deployment location etc.). Additionally, the number of permitted device licenses
needs to be accessed to determine whether a new Access Point can be adopted.
Refer to the following to set a device’s basic configuration, license and certificate usage:
•Basic Configuration
•Basic Device Configuration
•Auto Provisioning Policies
•Managing an Event Policy
•Managing MINT Policies
RF Domains allow administrators to assign configuration data to multiple devices deployed in a common coverage
area (floor, building or site). In such instances, there’s many configuration attributes these devices share as their
general client support roles are quite similar. However, device configurations may need periodic refinement
(overrides) from their original RF Domain administered design. For more information, see RF Domain Overrides on
page 5-32.
Profiles enable administrators to assign a common set of configuration parameters and policies to controller or
service platforms and Access Points. Profiles can be used to assign shared or unique network, wireless and security
parameters to wireless controllers and Access Points across a large, multi segment, site. The configuration
parameters within a profile are based on the hardware model the profile was created to support. The controller
and service platform supports both default and user defined profiles implementing new features or updating
existing parameters to groups of controllers, service platforms or Access Points.
However, device profile configurations may need periodic refinement from their original administered
configuration. Consequently, a device profile could be applied an override from the configuration shared amongst
numerous peer devices deployed within a particular site. For more information, see Profile Overrides on page 5-38.
Adoption is the process an Access Point uses to discover controller or service platforms available in the network,
pick the most desirable, establish an association, obtain its configuration and consider itself provisioned.
At adoption, an Access Point solicits and receives multiple adoption responses from available controllers or service
platforms on the network. Modify existing adoption policies or create a new one as needed to meet the adoption
requirements of a device and its assigned profile. For more information, see Auto Provisioning Policies on page 5-
268.
Lastly, use Configuration > Devices to define and manage a critical resource policy. A critical resource policy
defines a list of device IP addresses on the network (gateways, routers etc.). The support of these IP address is
interpreted as critical to the health of the network. These devices addresses are pinged regularly by the controller
or service platform. If there’s a connectivity issue, an event is generated stating a critical resource is unavailable.
For more information, see Overriding a Profile’s Critical Resource Configuration on page 5-233.

administrators to assign configuration data to multiple devices deployed in a common coverage area, such as in a
floor, building or site. Each RF Domain contains policies that can determine a Smart RF or WIPS configuration.
Profiles enable administrators to assign a common set of configuration parameters and policies to controllers,
service platforms and Access Points. Profiles can be used to assign common or unique network, wireless and
security parameters to wireless controllers and Access Points across a large, multi segment, site. The configuration
parameters within a profile are based on the hardware model the profile was created to support. A controller and
service platform support both default and user defined profiles implementing new features or updating existing
parameters to groups of peer devices and Access Points. The central benefit of a profile is its ability to update
devices collectively without having to modify individual device configurations one at a time.
To assign a device a Basic Configuration:
1 Select the Configuration tab from the Web UI.
2Select
Devices from the Configuration tab.
The Device Configuration screen displays a list of managed devices or peer controllers, service platforms or

The Basic Configuration screen displays by default.
NOTE: Once devices have been assigned membership in either a profile or RF
Domain, an administrator must be careful not to assign the device a configuration
update that removes it from membership from a RF Domain or profile. A RF
Domain or profile configuration must be re-applied to a device once its
configuration has been modified in a manner that differentiates it from the
configuration shared by the devices comprising the RF Domain or profile.

5.2.1 License Configuration
Basic Device Configuration
Licenses are purchased directly for the number of permissible adoptions per controller, service platform or
managed cluster.
Managing infrastructure devices requires a license key to enable software functionality or define the number of
adoptable devices permitted. My Licenses is a Web based online application enabling you to request a license key
for license certificates for products.
The Licenses screen also contains a facility where new licenses can be applied to increase the number of device
adoptions permitted, or to allow the use of the advanced security features.
Each controller and service platform family has multiple models to choose from that range from zero licenses to
the maximum number that can be loaded for that specific SKU.
To configure a device’s a license configuration:
1 Select the Configuration tab from the Web UI.
2Select
Devices from the Configuration tab.
The Device Configuration screen displays a list of managed devices or peer controllers, service platforms or

certificate and is called a CA certificate. A browser must contain the CA certificate in its Trusted Root Library so it
can trust certificates signed by the CA's private key.
Depending on the public key infrastructure, the digital certificate includes the owner's public key, the certificate
expiration date, the owner's name and other public key owner information. Each certificate is digitally signed by a
trustpoint. The trustpoint signing the certificate can be a certificate authority, corporation or individual. A
trustpoint represents a CA/identity pair containing the identity of the CA, CA-specific configuration parameters,
and an association with an enrolled identity certificate.
SSH keys are a pair of cryptographic keys used to authenticate users instead of, or in addition to, a username/
password. One key is private and the other is public key. Secure Shell (SSH) public key authentication can be used
by a requesting client to access resources, if properly configured. A RSA key pair must be generated on the client.
The public portion of the key pair resides with the controller or service platform, while the private portion remains
on a secure local area of the client.

lack of mistakes or corruption in the issuance of self signed certificates is central.
Self-signed certificates cannot be revoked which may allow an attacker who has already gained access to
monitor and inject data into a connection to spoof an identity if a private key has been compromised. However,
CAs have the ability to revoke a compromised certificate, preventing its further use.

5.2.2.4 Generating a Certificate Signing Request
Assigning Certificates
A certificate signing request (CSR) is a request to a certificate authority to apply for a digital identity certificate.
The CSR is a block of encrypted text generated on the server the certificate is used on. It contains the organization
name, common name (domain name), locality and country.
A RSA key must be either created or applied to the certificate request before the certificate can be generated. A
private key is not included in the CSR, but is used to digitally sign the completed request. The certificate created
with a particular CSR only works with the private key generated with it. If the private key is lost, the certificate is
no longer functional.The CSR can be accompanied by other identity credentials required by the certificate
authority, and the certificate authority maintains the right to contact the applicant for additional information.
If the request is successful, the CA sends an identity certificate digitally signed with the private key of the CA.
To create a CSR:
Certificate Subject

5.2.4 Wired 802.1x Configuration
Basic Device Configuration
802.1X is an IEEE standard for media-level (Layer 2) access control, providing the capability to permit or deny
connectivity based on user or device identity. 802.1X allows port based access using authentication. An 802.1X
enabled port can be dynamically enabled or disabled depending on user identity or device connection.
Source Select the GE port (1 - 24) used as the data source to span packets to the
selected destination port. The packets spanned from the selected source
to the destination depend on whether Inbound, Outbound or Any is
selected as the direction. A source port cannot be a destination port.
Destination Select the GE port (1 - 24) used as the port destination to span packets
from the selected source. The destination port serves as a duplicate
image of the source port and can be used to send packets to a network
diagnostic without disrupting the behavior on the original port. The
destination port transmits only mirrored traffic and does not forward
received traffic. Additionally, address learning is disabled on the
destination port.
Direction Define the direction data packets are spanned from the selected source
to the defined destination. Packets spanned from the source to the
destination depend on whether Inbound (received packets only),
Outbound (transmitted packets only) or Any (packets in either direction)
is selected.
Device Configuration
Wireless Controller and Service Platform System Reference Guide 5 - 31
Before authentication, the endpoint is unknown, and traffic is blocked. Upon authentication, the endpoint is known
and traffic is allowed. The controller or service platform uses source MAC filtering to ensure only the authenticated
endpoint is allowed to send traffic.

5.2.5 RF Domain Overrides
Basic Device Configuration
Use RF Domain Overrides to define configurations overriding the configuration set by the target device’s original
RF Domain assignment.
RF Domains allow administrators to assign configuration data to multiple devices deployed in a common coverage
area (floor, building or site). In such instances, there’s many configuration attributes these devices share, since their
general client support roles are quite similar. However, device configurations may need periodic refinement from
their original RF Domain administered design.
A controller or service platform configuration contains (at a minimum) one default RF Domain, but can optionally
use additional user defined RF Domains:
•Default RF Domain - Automatically assigned to each controller, service platform and associated Access Points
by default. A default RF Domain is unique to a specific model.
•User Defined RF Domains - Created by administrators and manually assigned to individual controllers, service
platforms or Access Points, but can be automatically assigned to Access Points using adoption policies.
Each controller, service platform and Access Point is assigned one RF Domain at a time. However, a user defined
RF Domain can be assigned to multiple devices as required. User defined RF Domains can be manually assigned or
automatically assigned to Access Points using an auto provisioning policy. The more devices assigned a single RF
Domain, the greater the likelihood one of the device’s configurations will require an override deviating that device’s
configuration from the original RF Domain assignment shared by the others.
To review the RF Domain’s original configuration requirements and the options available for a target device, refer
to Managing RF Domains on page 9-2.
To define a device’s RF Domain override configuration:
1 Select the Configuration tab from the Web UI.
2Select
Devices from the Configuration tab.
The Device Configuration screen displays a list of managed devices or peer controllers, service platforms or

5.2.6 Profile Overrides
Basic Device Configuration
Profiles enable administrators to assign a common set of parameters and policies to controllers, service platforms
and Access Points. Profiles can be used to assign shared or unique network, wireless and security parameters to
wireless controllers and Access Points across a large, multi segment, site. The configuration parameters within a
profile are based on the hardware model the profile was created to support. Controllers and service platforms
support both default and user defined profiles implementing new features or updating existing parameters to
groups of devices. The central benefit of a profile is its ability to update devices collectively without having to
modify individual device configurations. Power and Adoption overrides apply specifically to Access Points, while
Cluster configuration overrides apply to only controller or service platform configurations.
VLANS Use the spinner control to set a virtual interface ID (1 - 4094).
Wireless Client Limit Use the spinner control to set the number of users permitted on the
VLAN. Set the value to 0 to have an unlimited number of users.
NOTE: A blue override icon (to the left of a parameter) defines the parameter as

5.2.6.1 Cluster Configuration Overrides (Controllers and Service Platforms Only)
Profile Overrides
A redundancy group (cluster) is a set of controllers or service platforms (nodes) uniquely defined by a profile
configuration. Within the redundancy group, members discover and establish connections to other peers and
provide wireless self-healing support in the event of cluster member failure.
A cluster’s AP load balance is typically distributed evenly amongst the controllers or service platforms in the
cluster. Define how often this profile is load balanced for AP radio distribution as often as you feel required, as
radios can come and go and members can join and exit the cluster. For information on setting a profile’s original
cluster configuration (before applying an override), see Profile Cluster Configuration (Controllers and Service
Platforms) on page 8-8.
As cluster memberships increase or decrease and their load requirements change, a profile may need an override
applied to best suit a site’s cluster requirements.
To apply an override (if required) to a profile cluster configuration:
1 Select the Configuration tab from the Web UI.
2Select
Devices from the Configuration tab.
The Device Configuration screen displays a list of devices or peer controllers service platforms or Access
Points.
3 Select a target device (by double-clicking it) from amongst those displayed within the Device Configuration
screen.
Devices can also be selected directly from the Device Browser in the lower, left-hand, side of the UI.
4Select
Profile Overrides from the Device menu to expand it into sub menu options.
5Select
Cluster.
NOTE: A blue override icon (to the left of a parameter) defines the parameter as
having an override applied. To remove an override go to the Basic Configuration
section of the device and click the Clear Overrides button. This removes all
overrides from the device.

6 Optionally define the following Cluster Settings and overrides:
Cluster Mode A member can be in either an Active or Standby mode. All active
member controllers or service platforms can adopt Access Points.
Standby members only adopt Access Points when an active member
has failed or sees an Access Point that’s not yet adopted. The default
cluster mode is Active and enabled for use with the profile.
Cluster Name Define a name for the cluster name unique to its configuration or
profile support requirements. The name cannot exceed 64 characters.
Master Priority Set a priority value from 1 and 255 with the higher value being given
higher priority. This configuration is the device’s priority to become
cluster master. In cluster environment one device from cluster
members is elected as cluster master. This configuration is the device’s
priority to become cluster master. The default is 128.

that’s not yet adopted.
11 Select OK to save the changes and overrides made to the profile’s cluster configuration. Select Reset to revert
to the last saved configuration.
Handle STP
Convergence
Select the radio button to enable Spanning Tree Protocol (STP)
convergence for the controller or service platform. In general, this
protocol is enabled in layer 2 networks to prevent network looping.
Spanning Tree is a network layer protocol that ensures a loop-free
topology in a mesh network of inter-connected layer 2 controller or
service platform. The spanning tree protocol disables redundant
connections and uses the least costly path to maintain a connection
between any two controllers or service platforms in the network. If
enabled, the network forwards data only after STP convergence.
Enabling STP convergence delays the redundancy state machine
execution until the STP convergence is completed (the standard
protocol value for STP convergence is 50 seconds). Delaying the state
machine is important to load balance APs at startup. The default
setting is disabled.
Force Configured State Select the radio button to allow this controller or service platform to
take over for an active member if it were to fail. A standby controller or
service platform in the cluster takes over APs adopted by the failed
active member. If the failed active member were to come back up, the
active member starts a timer based on the Auto Revert Delay interval.
At the expiration of the Auto Revert Delay, the standby member
releases all adopted APs and goes back to a monitoring mode. The
Auto Revert Delay timer is stopped and restarted if the active member
goes down and comes up during the Auto Revert Delay interval. The
default value is disabled.
Force Configured State
Delay
Specify a delay interval in minutes (3 - 1,800). This is the interval a
standby member waits before releasing adopted APs and goes back to
a monitoring mode when an active cluster member becomes active
again after a failure. The default interval is 5 minutes.
Radius Counter DB Sync
Time
Specify a sync time (from 1 - 1,440 minutes) a RADIUS counter
database uses as its synchronization interval with the dedicated NTP
server resource. The default interval is 5 minutes.

5.2.6.2 Access Point Radio Power Overrides (Access Points Only)
Profile Overrides
A profile can manage the transmit output power of the Access Point radios it supports within the network.
Use the Power screen to set or override one of two power modes (3af or Auto) for a managed Access Point. When
automatic is selected, the Access Point safely operates within available power. Once the power configuration is
determined, the Access Point configures its operating power characteristics based on its model and power
configuration.
An Access Point uses a complex programmable logic device (CPLD). The CPLD determines proper supply
sequencing, the maximum power available and other status information. One of the primary functions of the CPLD
is to determine the Access Point’s maximum power budget. When an Access Point is powered on (or performing a
cold reset), the CPLD determines the maximum power provided by the POE device and the budget available to
the Access Point. The CPLD also determines the access point hardware SKU and the number of radios. If the
Access Point’s POE resource cannot provide sufficient power (with all intended interfaces enabled), some of the
following interfaces could be disabled or modified:
• The Access Point’s transmit and receive algorithms could be negatively impacted
• The Access Point’s transmit power could be reduced due to insufficient power
• The Access Point’s WAN port configuration could be changed (either enabled or disabled)
To define an Access Point’s power configuration or apply an override to an existing parameter:
1 Select the Devices tab from the Web UI.
2Select
Profile Overrides to expand its sub menu items.
3Select
Power.
A screen displays where an Access Point’s power configuration can be defined or overridden for a profile.
Figure 5-27 Access Point Profile Power Override screen
NOTE: The Power option only appears within the Profile Overrides menu tree if an
Access Point is selected from within the main Devices screen. Power management
is configured differently for controllers or service platforms, so the Power screen
only displays for Access Points.
NOTE: A blue override icon (to the left of a parameter) defines the parameter as
having an override applied. To remove an override go to the Basic Configuration
section of the device and click the Clear Overrides button. This removes all
overrides from the device.

4 Use the Power Mode drop-down menu to set or override the Power Mode Configuration on this AP.
When an Access Point is powered on for the first time, the system determines the power budget available to
the Access Point. Using the Automatic setting, the Access Point automatically determines the best power
configuration based on the available power budget. Automatic is the default setting.
If 802.3af is selected, the Access Point assumes 12.95 watts are available. If the mode is changed, the Access
Point requires a reset to implement the change. If 802.3at is selected, the Access Point assumes 23 - 26 watts
are available.
5 Set or override the Access Point radio’s 802.3af Power Mode and the radio’s 802.3at Power Mode.
Use the drop-down menu to define a mode of either Range or Throughput.
Select Throughput to transmit packets at the radio’s highest defined basic rate (based on the radio’s current
basic rate settings). This option is optimal in environments where the transmission range is secondary to
broadcast/multicast transmission performance. Select Range when range is preferred over performance for
broadcast/multicast (group) traffic. The data rates used for range are the lowest defined basic rates.
Throughput is the default setting for both 802.3af and 802.3at.

5.2.6.3 Access Point Adoption Overrides (Access Points Only)
Profile Overrides
Adoption is the process an Access Point uses to discover available controllers or service platforms, pick the most
desirable one, establish an association and optionally obtain an image upgrade and configuration. Adoption is
configurable and supported within a device profile and applied to other Access Points supported by the profile.
Individual attributes of an Access Point’s auto provisioning policy can be overridden as specific parameters require
modification.
At adoption, an Access Point solicits and receives multiple adoption responses from controllers and service
platforms available on the network. These adoption responses contain loading policy information the Access Point
uses to select the optimum controller or service platform for adoption. By default, an auto provisioning policy
generally distributes AP adoption evenly amongst available controllers and service platforms. Modify existing
adoption policies or create a new one as needed to meet the adoption requirements of a device and their assigned
profile.
An auto provisioning policy enables an administrator to define adoption rules for the supported Access Points
capable of being adopted by a wireless controller.
To define an Access Point’s adoption configuration or apply an override:
1 Select the Devices from the Web UI.
2Select
Profiles from the Configuration tab.
NOTE: Single radio model Access Point’s always operate using a full power
configuration. The power management configurations described in this section do
not apply to single radio models.
NOTE: A device configuration does not need to be present for an auto provisioning
policy to take effect. Once adopted, and the device’s configuration is defined and
applied by the controller or service platform, the auto provisioning policy mapping
does not have impact on subsequent adoptions by the same device.

5.2.7 Profile Interface Override Configuration
Profile Overrides
A profile’s interface configuration can be defined to support separate physical Ethernet configurations both unique
and specific to RFS4000, RFS6000 controllers and NX5500, NX7500 and NX9000 series service platforms. Ports
vary depending on platform, but controller or service platform models do have some of the same physical
interfaces.
A controller or service platform requires its Virtual Interface be configured for layer 3 (IP) access or layer 3 service
on a VLAN. A Virtual Interface defines which IP address is associated with each VLAN ID the controller or service
platform is connected to.
If the profile is configured to support an Access Point radio, an additional Radios option is available, unique to the
Access Point’s radio configuration.
Each profile interface configuration can have overrides applied to customize the configuration to a unique
controller or service platform deployment. However, once an override is applied to this configuration it becomes
independent from the profile that may be shared by a group of devices in a specific deployment and my need
careful administration until a profile can be re-applied to the target controller or service platform. For more

Mode Displays the profile’s switching mode as either Access or Trunk (as
defined within the Ethernet Port Basic Configuration screen). If Access is
selected, the listed port accepts packets only from the native VLAN.
Frames are forwarded untagged with no 802.1Q header. All frames
received on the port are expected as untagged and mapped to the native
VLAN. If set to Trunk, the port allows packets from a list of VLANs added
to the trunk. A port configured as Trunk supports multiple 802.1Q tagged
VLANs and one Native VLAN which can be tagged or untagged.
Native VLAN Lists the numerical VLAN ID (1 - 4094) set for the native VLAN. The
native VLAN allows an Ethernet device to associate untagged frames to a
VLAN when no 802.1Q frame is included in the frame. Additionally, the
native VLAN is the VLAN untagged traffic is directed over when using a
port in trunk mode.
Tag Native VLAN A green check mark defines the native VLAN as tagged. A red “X” defines
the native VLAN as untagged. When a frame is tagged, the 12 bit frame
VLAN ID is added to the 802.1Q header so upstream Ethernet devices
know which VLAN ID the frame belongs to. The device reads the 12 bit
VLAN ID and forwards the frame to the appropriate VLAN. When a frame
is received with no 802.1Q header, the upstream device classifies the
frame using the default or native VLAN assigned to the Trunk port. A
native VLAN allows an Ethernet device to associate untagged frames to a
VLAN when no 802.1Q frame is included in the frame.
Allowed VLANs Displays those VLANs allowed to send packets over the listed controller
or service platform port. Allowed VLANs are only listed when the mode
has been set to Trunk.

redirected to an authentication page. Authentication instead takes place when the RADIUS server is queried
against the wired user's MAC address. If the MAC address is in the RADIUS server's user database, the user can
pass traffic on the captive portal. If None is selected, captive portal policies are not enforced on the wired
interface. If Authentication Failure is selected, captive portal policies are enforced only when RADIUS
authentication of the client’s MAC address is not successful. If Always is selected, captive portal policies are
enforced regardless of whether the client's MAC address is in the RADIUS server's user database. For
information on configuring a captive portal policy, see Configuring Captive Portal Policies on page 11-1.

16 Select the Security tab.
Mode Select either the Access or Trunk radio button to set the VLAN switching
mode over the port. If Access is selected, the port accepts packets only
form the native VLANs. Frames are forwarded out the port untagged with
no 802.1Q header. All frames received on the port are untagged and are
mapped to the native VLAN. If the mode is set to Trunk, the port allows
packets from a list of VLANs you add to the trunk. A port configured as
Trunk supports multiple 802.1Q tagged VLANs and one Native VLAN
which can be tagged or untagged. Access is the default mode.
Native VLAN Use the spinner control to define a numerical Native VLAN ID from 1 -
4094. The native VLAN allows an Ethernet device to associate untagged
frames to a VLAN when no 802.1Q frame is included in the frame.
Additionally, the native VLAN is the VLAN which untagged traffic will be
directed over when using a port in trunk mode. The default VLAN is 1.
Tag Native VLAN Select this option to tag the native VLAN. Controller and service
platforms support the IEEE 802.1Q specification for tagging frames and
coordinating VLANs between devices. IEEE 802.1Q adds four bytes to
each frame identifying the VLAN ID for upstream devices that the frame
belongs. If the upstream Ethernet device does not support IEEE 802.1Q
tagging, it does not interpret the tagged frames. When VLAN tagging is
required between devices, both devices must support tagging and be
configured to accept tagged VLANs. When a frame is tagged, the 12 bit
frame VLAN ID is added to the 802.1Q header so upstream Ethernet
devices know which VLAN ID the frame belongs to. The device reads the
12 bit VLAN ID and forwards the frame to the appropriate VLAN. When a
frame is received with no 802.1Q header, the upstream device classifies
the frame using the default or native VLAN assigned to the Trunk port.
The native VLAN allows an Ethernet device to associate untagged frames
to a VLAN when no 802.1Q frame is included in the frame. This feature is
disabled by default.
Allowed VLANs Selecting Trunk as the mode enables the Allowed VLANs parameter. Add
VLANs that exclusively send packets over the listed port.

slower the media, the higher the cost.
Enable as Edge Port Select this option to define this port as an edge port. Using an edge
(private) port, you can isolate devices to prevent connectivity over this
port.
Link Type Select either the Point-to-Point or Shared radio button. Selecting Point-
to-Point indicates the port should be treated as connected to a point-to-
point link. Selecting Shared indicates this port should be treated as having
a shared connection. A port connected to a hub is on a shared link, while
one connected to a controller or service platform is a point-to-point link.
Cisco MSTP
Interoperability

Force Protocol
Version
Sets the protocol version to either STP(0), Not Supported(1), RSTP(2) or
MSTP(3). MSTP is the default setting.
Guard Determines whether the port enforces root bridge placement. Setting the
guard to Root ensures the port is a designated port. Typically, each guard
root port is a designated port, unless two or more ports (within the root
bridge) are connected together. If the bridge receives superior BPDUs on
a guard root-enabled port, the guard root moves the port to a root-
inconsistent STP state. This state is equivalent to a listening state. No data
is forwarded across the port. Thus, the guard root enforces the root
bridge position.

packets before being sent. A PPPoE client should be able to maintain its
point-to-point connection for this defined MTU size. The default MTU is
1,492.
IPv6 MTU Set an IPv6 MTU for this virtual interface from 1,280 - 1,500. A larger MTU
provides greater efficiency because each packet carries more user data
while protocol overheads, such as headers or underlying per-packet
delays, remain fixed; the resulting higher efficiency means a slight
improvement in bulk protocol throughput. A larger MTU results in the
processing of fewer packets for the same amount of data. The default is
1,500.

11 Define or override the following Switching Mode parameters to apply to the port channel configuration:
Speed Select the speed at which the port channel can receive and transmit data.
Select either 10 Mbps, 100 Mbps or 1000 Mbps to establish a 10, 100 or
1000 Mbps data transfer rate for the selected half duplex or full duplex
transmission. These options are not available if Auto is selected. Select
Automatic to allow the port channel to automatically exchange
information about data transmission speeds and duplex capabilities. Auto
negotiation is helpful in an environment where different devices are
connected and disconnected on a regular basis. Automatic is the default
setting.
Duplex Select either half, full or automatic as the duplex option. Select Half
duplex to send data over the port channel, then immediately receive data
from the same direction in which the data was transmitted. Like a full-
duplex transmission, a half-duplex transmission can carry data in both
directions, just not at the same time. Select Full duplex to transmit data to
and from the port channel at the same time. Using full duplex, the port
channel can send data while receiving data as well. Select Automatic to
enable to the controller or service platform to dynamically duplex as port
channel performance needs dictate. Automatic is the default setting.
Mode Select either the Access or Trunk radio button to set the VLAN switching
mode over the port channel. If Access is selected, the port channel
accepts packets only from the native VLAN. Frames are forwarded
untagged with no 802.1Q header. All frames received on the port are
expected as untagged and are mapped to the native VLAN. If the mode is
set to Trunk, the port channel allows packets from a list of VLANs you
add to the trunk. A port channel configured as Trunk supports multiple
802.1Q tagged VLANs and one Native VLAN which can be tagged or
untagged. Access is the default setting.
Native VLAN Use the spinner control to define a numerical Native VLAN ID from
1 - 4094. The native VLAN allows an Ethernet device to associate
untagged frames to a VLAN when no 802.1Q frame is included in the
frame. Additionally, the native VLAN is the VLAN untagged traffic will be
directed over when using trunk mode. The default value is 1.

14 Refer to the Access Control section. As part of the port channel’s security configuration, Inbound IPv4 IP, IPv6
IP and MAC address firewall rules are required.
Tag the Native VLAN Select this option to tag the native VLAN. Controllers and service
platforms support the IEEE 802.1Q specification for tagging frames and
coordinating VLANs between devices. IEEE 802.1Q adds four bytes to
each frame identifying the VLAN ID for upstream devices that the frame
belongs. If the upstream Ethernet device does not support IEEE 802.1Q
tagging, it does not interpret the tagged frames. When VLAN tagging is
required between devices, both devices must support tagging and be
configured to accept tagged VLANs. When a frame is tagged, a 12 bit
frame VLAN ID is added to the 802.1Q header, so upstream Ethernet
devices know which VLAN ID the frame belongs to. The device reads the
12 bit VLAN ID and forwards the frame to the appropriate VLAN. When a
frame is received with no 802.1Q header, the upstream device classifies
the frame using the default or native VLAN assigned to the Trunk port.
The native VLAN allows an Ethernet device to associate untagged frames
to a VLAN when no 802.1Q frame is included in the frame. This setting is
disabled by default.
Allowed VLANs Selecting Trunk as the mode enables the Allowed VLANs parameter. Add
VLANs that exclusively send packets over the port channel.

The designated cost is the cost for a packet to travel from this port to the root in the MSTP configuration. The
slower the media, the higher the cost.
27 Refer to the Spanning Tree Port Priority table.
Define or override an Instance Index using the spinner control, then set the Priority. The lower the priority, the
greater likelihood of the port becoming a designated port.
Enable as Edge Port Select this option to define this port as an edge port. Using an edge
(private) port, you can isolate devices to prevent connectivity over this
port channel. This setting is disabled by default.
Link Type Select either the Point-to-Point or Shared radio button. Selecting Point-
to-Point indicates the port should be treated as connected to a point-to-
point link. Selecting Shared indicates this port should be treated as
having a shared connection. A port connected to a hub is on a shared
link, while one connected to a controller or service platform is a point-
to-point link. Point-to-Point is the default setting.
Cisco MSTP
Interoperability
Select either the Enable or Disable radio buttons. This enables
interoperability with Cisco’s version of MSTP, which is incompatible with
standard MSTP. This setting is disabled by default.
Force Protocol Version Sets the protocol version to either STP(0), Not Supported(1), RSTP(2) or
MSTP(3). MSTP is the default setting.
Guard Determines whether the port channel enforces root bridge placement.
Setting the guard to Root ensures the port is a designated port.
Typically, each guard root port is a designated port, unless two or more
ports (within the root bridge) are connected together. If the bridge
receives superior (BPDUs) on a guard root-enabled port, the guard root
moves the port to a root-inconsistent STP state. This state is equivalent
to a listening state. No data is forwarded across the port. Thus, the
guard root enforces the root bridge position.

5.2.7.4 VM Interface Override Configuration
Profile Interface Override Configuration
WiNG provides a dataplane bridge for external network connectivity for Virtual Machines (VMs). VM Interfaces
define which IP address is associated with each VLAN ID the service platform is connected to and enables remote
service platform administration. Each custom VM can have up to a maximum of two VM interfaces. Each VM
interface can be mapped to one of sixteen VMIF ports on the dataplane bridge. This mapping determines the
destination for service platform routing.
By default, VM interfaces are internally connected to the dataplane bridge via VMIF1. VMIF1 is an untagged port
providing access to VLAN 1 to support the capability to connect the VM interfaces to any of the VMIF ports. This
provides the flexibility to move a VM interface onto different VLANs as well as configure specific firewall and QOS
rules.

9 Set or override the following profile Radio Settings for the selected Access Point radio.
Description Provide or edit a description (1 - 64 characters in length) for the radio that
helps differentiate it from others with similar configurations.
Admin Status Either select the Enabled or Disabled radio button to define this radio’s
current status within the network. When enabled, the Access Point is
operational and available for client support within the network. The radio
is enabled by default and must be manually shutdown.
Radio QoS Policy Use the drop-down menu to specify an existing QoS policy to apply to the
Access Point radio in respect to its intended radio traffic. If there’s no
existing suiting the radio’s intended operation, select the Create icon to
define a new QoS policy that can be applied to this profile. For more
information, see Radio QoS Policy on page 6-66.
Association ACL Use the drop-down menu to specify an existing Association ACL policy to
apply to the Access Point radio. An Association ACL is a policy-based
Access Control List (ACL) that either prevents or allows wireless clients
from connecting to a managed Access Point radio. An ACL is a sequential
collection of permit and deny conditions that apply to controller or service
platform packets. When a packet is received on an interface, the controller
or service platform compares the fields in the packet against any applied
ACLs to verify the packet has the required permissions to be forwarded,
based on the criteria specified in the access lists. If a packet does not
meet any of the criteria specified in the ACL, the packet is dropped. Select
the Create icon to define a new Association ACL that can be applied to
this profile.
RF Mode Set the mode to either 2.4 GHz WLAN or 5 GHz WLAN depending on the
radio’s intended client support requirement. Set the mode to Sensor if
using the radio for rogue device detection. To set a radio as a detector,
disable sensor support on the other Access Point radio. Set the mode to
scan-ahead in DFS aware countries to allow a mesh points secondary
radio to scan for an alternative channel for backhaul transmission in the
event of a radar event on the principal radio. The secondary radio is
continually monitoring the alternate channel, which means the principal
radio can switch channels and transmit data immediately without waiting
for the channel availability check.
Lock RF Mode Select this option to lock Smart RF for this radio. The default setting is
disabled.
Channel Use the drop-down menu to select the channel of operation for the radio.
Only a trained installation professional should define the radio channel.
Select Smart for the radio to scan non-overlapping channels listening for
beacons from other Access Points. After channels are scanned, the radio
selects the channel with the fewest Access Points. In the case of multiple
Access Points on the same channel, it selects the channel with the lowest
average power level. The default value is Smart. Channels with a “w”
appended to them are unique to the 40 MHz band. Channels with a “ww”
appended to them are 802.11ac specific, only appear when using an
AP8232, and are unique to the 80 MHz band.
DFS Revert Home Select this option to revert to the home channel after a DFS evacuation
period.
Device Configuration
Wireless Controller and Service Platform System Reference Guide 5 - 93
DFS Duration Set the DFS duration between 30 to 3,600 minutes. This is the duration
for which the radio stays in the in the new channel. The default value is 90
minutes.
Transmit Power Set the transmit power of the selected Access Point radio. If using a dual
or three radio model Access Point, each radio should be configured with a
unique transmit power in respect to its intended client support function.
Select the Smart RF option to let Smart RF determine the transmit power.
A setting of 0 defines the radio as using Smart RF to determine its output
power. 20 dBm is the default value.
Antenna Gain Set the antenna between 0.00 - 15.00 dBm. The access point’s Power
Management Antenna Configuration File (PMACF) automatically
configures the access point’s radio transmit power based on the antenna
type, its antenna gain (provided here) and the deployed country’s
regulatory domain restrictions. Once provided, the access point calculates
the power range. Antenna gain relates the intensity of an antenna in a
given direction to the intensity that would be produced ideally by an
antenna that radiates equally in all directions (isotropically), and has no
losses. Although the gain of an antenna is directly related to its directivity,
its gain is a measure that takes into account the efficiency of the antenna
as well as its directional capabilities. Only a professional installer should
set the antenna gain. The default value is 0.00.
Antenna Mode Set the number of transmit and receive antennas on the Access Point. 1x1
is used for transmissions over just the single “A” antenna, 1x3 is used for
transmissions over the “A” antenna and all three antennas for receiving.
2x2 is used for transmissions and receipts over two antennas for dual
antenna models. The default setting is dynamic based on the Access Point
model deployed and its transmit power settings.
Enable Antenna
Diversity
Select this option to enable antenna diversity on supported antennas.
Antenna diversity uses two or more antennas to increase signal quality
and strength. This option is disabled by default.
Adaptivity Recovery Select this option to switch channels when an Access Point‘s radio is in
adaptivity mode. In adaptivity mode, an Access Point monitors
interference on its set channel and stops functioning when the radio’s
defined interference tolerance level is exceeded. When the defined
adaptivity timeout is exceeded, the radio resumes functionality on a
different channel. This option is enabled by default.
Adaptivity Timeout Set the adaptivity timeout from 30 to 3,600 minutes. The default setting
is 90 minutes.
Wireless Client
Power
Select this option to specify the transmit power on supported wireless
clients. If this is enabled set a client power level between 0 to 20 dBm.

Rate Use the Select button to set rate options depending on the 802.11
protocols selected. If the radio band is set to Sensor or Detector, the Data
Rates drop-down menu is not enabled, as the rates are fixed and not user
configurable. If 2.4 GHz is selected as the radio band, select separate
802.11b, 802.11g and 802.11n rates and define how they are used in
combination. If 5 GHz is selected as the radio band, select separate 802.11a
and 802.11n rates then define how they are used together. When using
802.11n (in either the 2.4 or 5 GHz band), Set a MCS (modulation and
coding scheme) in respect to the radio’s channel width and guard interval.
A MCS defines (based on RF channel conditions) an optimal combination
of 8 data rates, bonded channels, multiple spatial streams, different guard
intervals and modulation types. Clients can associate as long as they
support basic MCS (as well as non-11n basic rates).
If dedicating an AP81XX model radio to either 2.4 or 5 Ghz support, a
Custom Rates option is available to set a modulation and coding scheme
(MCS) in respect to the radio’s channel width and guard interval. A MCS
defines (based on RF channel conditions) an optimal combination of rates,
bonded channels, multiple spatial streams, different guard intervals and
modulation types. Clients can associate as long as they support basic MCS
(as well as non-11n basic rates). If Basic is selected within the 802.11n Rates
field, the MCS0-7 option is auto selected as a Supported rate and that
option is greyed out. If Basic is not selected, any combination of MCS0-7,
MCS8-15 and MCS16-23 can be supported, including a case where MCS0-7
and MCS16-23 are selected and not MCS8-15. The MCS0-7 and MCS8-15
options are available to each support Access Point. However, the MCS16-
23 option is only available to AP81XX model Access Points and its ability
to provide 3x3x3 MIMO support.
Radio Placement Use the drop-down menu to specify whether the radio is located Indoors
or Outdoors. The placement should depend on the country of operation
selected and its regulatory domain requirements for radio emissions. The
default setting is Indoors.
Max Clients Use the spinner control to set a maximum permissible number of clients
to connect with this radio. The available range is from 0 - 256 clients. The
default is 256.
Rate Selection
Methods
Specify a radio selection method for the radio. The selection methods are:
Standard - standard monotonic radio selection method will be used.
Opportunistic - sets opportunistic radio link adaptation (ORLA) as the
radio selection method. This mode uses opportunistic data rate selection
to provide the best throughput. The ORLA rate selection mode is
supported only on the AP7161 and AP8163 model Access Points.
Device Configuration
Wireless Controller and Service Platform System Reference Guide 5 - 95
10 Set or override the following profile WLAN Properties for the selected Access Point radio:
Beacon Interval Set the interval between radio beacons in milliseconds (either 50, 100 or
200). A beacon is a packet broadcast by adopted radios to keep the
network synchronized. Included in a beacon is the WLAN service area,
radio address, broadcast destination addresses, a time stamp, and
indicators about traffic and delivery (such as a DTIM). Increase the DTIM/
beacon settings (lengthening the time) to let nodes sleep longer and
preserve battery life. Decrease these settings (shortening the time) to
support streaming-multicast audio and video applications that are jitter-
sensitive. The default value is 100 milliseconds.
DTIM Interval Set a DTIM Interval to specify a period for Delivery Traffic Indication
Messages (DTIM). A DTIM is periodically included in a beacon frame
transmitted from adopted radios. The DTIM indicates broadcast and
multicast frames (buffered at the Access Point) are soon to arrive. These
are simple data frames that require no acknowledgment, so nodes
sometimes miss them. Increase the DTIM/ beacon settings (lengthening
the time) to let nodes sleep longer and preserve their battery life.
Decrease these settings (shortening the time) to support streaming
multicast audio and video applications that are jitter-sensitive.
RTS Threshold Specify a Request To Send (RTS) threshold (between 1 - 65,636 bytes) for
use by the WLAN's adopted Access Point radios. RTS is a transmitting
station's signal that requests a Clear To Send (CTS) response from a
receiving client. This RTS/CTS procedure clears the air where clients are
contending for transmission time. Benefits include fewer data collisions
and better communication with nodes that are hard to find (or hidden)
because of other active nodes in the transmission path.
Control RTS/CTS by setting an RTS threshold. This setting initiates an
RTS/CTS exchange for data frames larger than the threshold, and sends
(without RTS/CTS) any data frames smaller than the threshold.
Consider the trade-offs when setting an appropriate RTS threshold for the
WLAN's Access Point radios. A lower RTS threshold causes more frequent
RTS/CTS exchanges. This consumes more bandwidth because of
additional latency (RTS/CTS exchanges) before transmissions can
commence. A disadvantage is the reduction in data-frame throughput. An
advantage is quicker system recovery from electromagnetic interference
and data collisions. Environments with more wireless traffic and
contention for transmission make the best use of a lower RTS threshold.
A higher RTS threshold minimizes RTS/CTS exchanges, consuming less
bandwidth for data transmissions. A disadvantage is less help to nodes
that encounter interference and collisions. An advantage is faster data-
frame throughput. Environments with less wireless traffic and contention
for transmission make the best use of a higher RTS threshold.
Short Preamble If using an 802.11bg radio, select this option to transmit using a short
preamble. Short preambles improve throughput. However, some devices
(SpectraLink/Polycomm phones) require long preambles. The default
value is disabled.

11 Select a mode from the Feed WLAN Packets to Sensor check box in the Radio Share section to enable this
feature. Select either Inline or Promiscuous mode to allow the packets the radio is switching to also be used by
the WIPS analysis module. This feature can be enabled in two modes: an inline mode where the WIPS sensor
receives the packets from the radios with radio operating in normal mode. A promiscuous mode where the
radio is configured to a mode where it receives all packets on the channel whether the destination address is
the radio or not, and the WIPS module can analyze them.
12 Select the WLAN Mapping/Mesh Mapping tab.

13 Refer to the WLAN/BSS Mappings field to set or override WLAN BSSID assignments for an existing Access
Point deployment.
Guard Interval Use the drop-down menu to specify a Long or Any guard interval. The
guard interval is the space between characters being transmitted. The
guard interval eliminates inter-symbol interference (ISI). ISI occurs when
echoes or reflections from one character interfere with another character.
Adding time between transmissions allows echo's and reflections to settle
before the next character is transmitted. A shorter guard interval results in
shorter character times which reduces overhead and increases data rates
by up to 10%. The default value is Long.
Probe Response Rate Use the drop-down menu to specify the data rate used for the
transmission of probe responses. Options include, highest-basic, lowest-
basic and follow-probe-request (default setting).

deactivates all mesh activity on this radio. Setting the mesh mode to
Portal turns the radio into a mesh portal. This will start the radio
beaconing immediately and will accept connections from other mesh
nodes. Setting the mesh mode to client enables the radio to operate as a
mesh client that scans and connects to mesh portals or nodes connected
to portals.

20 Select the Client Bridge Settings tab to configure the selected radio as a client-bridge. Note, before configuring
the client-bridge parameters, set the radio's rf-mode to bridge.
An Access Point's radio can be configured to form a bridge between its wireless/wired clients and an
infrastructure WLAN. The bridge radio authenticates and associates with an infrastructure WLAN Access Point.
After successful association, the Access Point switches frames between its bridge radio and wired/wireless
client(s) connected either to its GE port(s) or to the other radio, there by providing the clients access to the
infrastructure WLAN resources. This feature is supported only on the AP6522, AP6562, AP7602, AP7532,
AP7562, AP7602, and AP7622 model Access Points.
Mesh Links Specify the number of mesh links allowed by the radio. The radio can
have from 1- 6 mesh links when the radio is configured as a Portal.
Mesh PSK Provide the encryption key in either ASCII or Hex format. Administrators
must ensure this key is configured on the Access Point when staged for
mesh, added to the mesh client and to the portal Access Point’s

33 Set or override the following Aeroscout Properties:
RIFS Mode Define a RIFS mode to determine whether interframe spacing is applied
to Access Point transmissions or received packets, both, or neither The
default mode is Transmit and Receive. Interframe spacing is an interval
between two consecutive Ethernet frames to enable a brief recovery
between packets and allow target devices to prepare for the reception of
the next packet. Consider setting this value to None for high priority
traffic to reduce packet delay.
STBC Mode Select a space–time block coding (STBC) option to transmit multiple data
stream copies across Access Point antennas to improve signal reliability.
An Access Point’s transmitted signal traverses a problematic environment,
with scattering, reflection and refraction all prevalent. The signal can be
further corrupted by noise at the receiver. Consequently, some of the
received data copies are less corrupt and better than others. This
redundancy means there’s a greater chance of using one, or more, of the
received copies to successfully decode the signal. STBC effectively
combines all the signal copies to extract as much information from each
as possible.
Transmit
Beamforming
Enable beamforming to steer signals to peers in a specific direction to
enhance signal strength and improve throughput amongst meshed
devices (not clients). Each Access Point radio support up to 16
beamforming capable mesh peers. When enabled, a beamformer steers
its wireless signals to its peers. A beamformee device assists the
beamformer with channel estimation by providing a feedback matrix. The
feedback matrix is a set of values sent by the beamformee to assist the
beamformer in computing a steering matrix. A steering matrix is an
additional set of values used to steer wireless signals at the beamformer
so constructive signals arrive at the beamformee for better SNR and
throughput. Any beamforming capable mesh peer connecting to a radio
whose capacity is exhausted cannot enable beamforming itself. Transmit
beamforming is available on AP81XX (AP8122, AP8132 and AP8163) model
Access Points only, and is disabled by default.
Forwarding Host Specify the Aeroscout engine’s IP address. When specified, the AP

5.2.7.6 WAN Backhaul Override Configuration
Profile Interface Override Configuration
A Wireless Wide Area Network (WWAN) card is a specialized network interface card that allows a device to
connect, transmit and receive data over a Cellular Wide Area Network. The RFS4000 and RFS6000 each have a
PCI Express card slot that supports 3G WWAN cards. The WWAN card uses point to point protocol (PPP) to
connect to the Internet Service Provider (ISP) and gain access to the Internet. PPP is the protocol used for
establishing internet links over dial-up modems, DSL connections, and many other types of point-to-point
communications. PPP packages your system’s TCP/IP packets and forwards them to the serial device where they
can be put on the network. PPP is a full-duplex protocol that can be used on various physical media, including
twisted pair or fiber optic lines or satellite transmission. It uses a variation of High Speed Data Link Control (HDLC)
for packet encapsulation.

5.2.7.7 PPPoE Override Configuration
Profile Interface Override Configuration
PPP over Ethernet (PPPoE) is a data-link protocol for dialup connections. PPPoE allows the access point to use a
broadband modem (DSL, cable modem, etc.) for access to high-speed data and broadband networks. Most DSL
providers support (or deploy) the PPPoE protocol. PPPoE uses standard encryption, authentication, and
compression methods as specified by the PPPoE protocol. PPPoE enables controllers, service platforms and Access
Points to establish a point-to-point connection to an ISP over existing Ethernet interface.
To provide this point-to-point connection, each PPPoE session learns the Ethernet address of a remote PPPoE
client, and establishes a session. PPPoE uses both a discover and session phase to identify a client and establish a
point-to-point connection. By using such a connection, a Wireless WAN fail over is available to maintain seamless
network access if the access point’s Wired WAN were to fail.
NAT Direction Define the Network Address Translation (NAT) direction. Options include:
Inside - The inside network is transmitting data over the network its
intended destination. On the way out, the source IP address is changed in
the header and replaced by the (public) IP address.
Outside - Packets passing through the NAT on the way back to the
controller or service platform managed LAN are searched against to the
records kept by the NAT engine. There, the destination IP address is
changed back to the specific internal private class IP address in order to
reach the LAN over the network.
None - No NAT activity takes place. This is the default setting.
IPv4 Inbound
Firewall Rules
Use the drop-down menu to select an inbound IPv4 ACL to associate with
traffic on the WAN backhaul. This setting pertains to IPv4 inbound traffic
only and not IPv6. IPv4 operates as a best effort delivery method, as it
does not guarantee delivery, and does not ensure proper sequencing or
duplicate delivery (unlike (TCP). IPv4 hosts can use link local addressing
to provide local connectivity. If an appropriate IP ACL does not exist,
select the Add button to create a new one.
VPN Crypto Map If necessary, specify a crypto map for the wireless WAN. A crypto map
can be up to 256 characters long. If a suitable crypto map is not available,
click the Create button to configure a new one.
WWAN Default Route
Priority
Use the spinner control to define a priority from 1 - 8,000 for the default
route learned by the wireless WAN. The default value is 3000.
NOTE: Devices with PPPoE enabled continue to support VPN, NAT, PBR and 3G fail
over on the PPPoE interface. Multiple PPPoE sessions are supported using a single
user account user account if RADIUS is configured to allow simultaneous access.
Device Configuration
Wireless Controller and Service Platform System Reference Guide 5 - 108
When PPPoE client operation is enabled, it discovers an available server and establishes a PPPoE link for traffic
slow. When a wired WAN connection failure is detected, traffic flows through the WWAN interface in fail-over
mode (if the WWAN network is configured and available). When the PPPoE link becomes accessible again, traffic
is redirected back through the access point’s wired WAN link.
When the access point initiates a PPPoE session, it first performs a discovery to identify the Ethernet MAC address
of the PPPoE client and establish a PPPoE session ID. In discovery, the PPPoE client discovers a server to host the
PPPoE connection.
To create a PPPoE point-to-point configuration:

8 Define the following Connection settings for the PPPoE point-to-point connection with the PPPoE client:
9Set the Network Address Translation (NAT) direction for the PPPoE configuration.
Network Address Translation (NAT) converts an IP address in one network to a different IP address or set of IP
addresses in another network. The access point router maps its local (Inside) network addresses to WAN
(Outside) IP addresses, and translates the WAN IP addresses on incoming packets to local IP addresses. NAT is
useful because it allows the authentication of incoming and outgoing requests, and minimizes the number of
WAN IP addresses needed when a range of local IP addresses is mapped to each WAN IP address. The default
setting is None (neither inside or outside).
10 Define the following Security Settings for the PPPoE configuration:
11 Use the spinner control to set the Default Route Priority for the default route obtained using PPPoE.

MSCHAP, and MSCHAP-v2.
Maximum
Transmission Unit
(MTU)
Set the PPPoE client maximum transmission unit (MTU) from 500 - 1,492.
The MTU is the largest physical packet size in bytes a network can
transmit. Any messages larger than the MTU are divided into smaller
packets before being sent. A PPPoE client should be able to maintain its
point-to-point connection for this defined MTU size. The default MTU is
1,492.
Client Idle Timeout Set a timeout in either Seconds (1 - 65,535), Minutes (1 - 1,092) or Hours.
The Access Point uses the defined timeout so it does not sit idle waiting
for input from the PPPoE client and server that may never come. The
default setting is 10 minutes.
Keep Alive Select this option to ensure the point-to-point connect to the PPPoE
client is continuously maintained and not timed out. This setting is
disabled by default.

5.2.7.8 Bluetooth Configuration
Profile Interface Override Configuration
AP-8432 and AP-8533 model Access Points utilize a built in Bluetooth chip for specific Bluetooth functional
behaviors in a WiNG managed network. AP-8432 and AP-8533 models support both Bluetooth classic and
Bluetooth low energy technology. These platforms can use their Bluetooth classic enabled radio to sense other
Bluetooth enabled devices and report device data (MAC address, RSSI and device calls) to an ADSP server for
intrusion detection. If the device presence varies in an unexpected manner, ADSP can raise an alarm.
AP-8432 and AP-8533 model Access Points support Bluetooth beaconing to emit either iBeacon or Eddystone-
URL beacons. The Access Point’s Bluetooth radio sends non-connectable, undirected low-energy (LE)
advertisement packets on a periodic basis. These advertisement packets are short, and sent on Bluetooth
advertising channels that conform to already-established iBeacon and Eddystone-URL standards. Portions of the
advertising packet are still customizable however.

Beacon Transmission
Pattern
When the Bluetooth radio’s mode is set to le-beacon, use the enabled
drop-down menu to set the beacon’s emitted transmission pattern to
either eddystone_url1, eddystone_url2 or ibeacon. An eddystone-URL
frame broadcasts a URL using a compressed encoding scheme to
better fit within a limited advertisement packet. Once decoded, the
URL can be used by a client for Internet access. iBeacon was created
by Apple for use in iOS devices (beginning with iOS version 7.0). There
are three data fields Apple has made available to iOS applications, a
UUID for device identification, a Major value for device class and a
Minor value for more refined information like product category.
Eddystone Beacon
Calibration Signal
Strength
Set the eddystone beacon measured calibration signal strength, from -
127 to 127 dBm, at 0 meters. Mobile devices can approximate their
distance to beacons based on received signal strength. However,
distance readings can fluctuate since they depend on several external
factors. The closer you are to a beacon, the more accurate the
reported distance. This setting is the projected calibration signal
strength at 0 meters. The default setting is -19 dBm.
URL-1 to Transmit
Eddystone-URL
Enter a 64 character maximum eddystone-URL1. The URL must be 18
characters or less once auto-encoding is applied. The encoding process
is for getting the URL to fit within the beacon’s payload.
URL-2 to Transmit
Eddystone-URL
Enter a 64 character maximum eddystone-URL2. The URL must be 18
characters or less once auto-encoding is applied. The encoding process
is for getting the URL to fit within the beacon’s payload.
iBeacon Calibration
Signal Strength
Set the ibeacon measured calibration signal strength, from -127 to 127
dBm, at 1 meter. Mobile devices can approximate their distance to
beacons based on received signal strength. However, distance readings
can fluctuate since they depend on several external factors. The closer
you are to a beacon, the more accurate the reported distance. This
setting is the projected calibration signal strength at 1 meter. The
default setting is -60 dBm.
iBeacon Major Number Set the iBeacon Major value from 0 - 65,535. Major values identify
and distinguish groups. For example, each beacon on a specific floor in
a building could be assigned a unique major value. The default is 1,111.
iBeacon Minor Number Set the iBeacon Minor value from 0 - 65,535. Minor values identify and
distinguish individual beacons. Minor values help identify individual
beacons within a group of beacons assigned a major value. The
default setting is 2,222.
iBeacon UUID Define a 32 hex character maximum UUID. The Universally Unique
IDentifier (UUID) classification contains 32 hexadecimal digits. The
UUID distinguishes iBeacons in the network from all other beacons in
networks outside of your direct administration.

5.2.8 Overriding a Profile’s Network Configuration
Profile Overrides
Setting a profile’s network configuration is a large task comprised of numerous administration activities. Each of
the activities described below can have an override applied to the original profile configuration. Applying an
override removes the device from the profile configuration that may be shared by other devices and requires
careful administration to ensure this one device still supports the deployment requirements within the managed
network.
A profile’s network configuration process consists of the following:
•Overriding a Profile’s DNS Configuration
•Overriding a Profile’s ARP Configuration
•Overriding a Profile’s L2TPV3 Configuration
•Overriding a Profile’s GRE Configuration
•Overriding a Profile’s IGMP Snooping Configuration

5.2.8.1 Overriding a Profile’s DNS Configuration
Overriding a Profile’s Network Configuration
Domain Naming System (DNS) DNS is a hierarchical naming system for resources connected to the Internet or a
private network. Primarily, the controller or service platform’s DNS resources translate domain names into IP
addresses. If a DNS server doesn't know how to translate a particular domain name, it asks another one until the
correct IP address is returned. DNS enables access to resources using human friendly notations. DNS converts
human friendly domain names into notations used by networking equipment for locating resources.
As a resource is accessed (using human-friendly hostnames), it’s possible to access the resource even if the
underlying machine friendly notation name changes. Without DNS you need to remember a series of numbers
(123.123.123.123) instead of a domain name (www.domainname.com).
Controllers and service platforms maintain their own DNS facility that can assist in domain name translation. A
DNS assignment can be overridden as needed, but removes the device configuration from the managed profile
that may be shared with other similar device models.
To define the DNS configuration or apply overrides to an existing configuration:

5.2.8.2 Overriding a Profile’s ARP Configuration
Overriding a Profile’s Network Configuration
Address Resolution Protocol (ARP) is a protocol for mapping an IP address to a hardware MAC address recognized
on the managed network. ARP provides rules for making this correlation and providing address conversion in both
directions. ARP assignment s can be overridden as needed, but an override removes the device configuration from
the managed profile that may be shared with other similar device models.
When an incoming packet destined for a host arrives at the controller or service platform, the gateway uses ARP
to find a physical host or MAC address that matches the IP address. ARP looks in its ARP cache and, if it finds the
address, provides it so the packet can be converted to the right packet length and format and sent to the
destination. If no entry is found for the IP address, ARP broadcasts a request packet in a special format to all the
machines on the LAN to see if one machine knows that it has that IP address associated with it. A machine that
recognizes the IP address as its own returns a reply so indicating. ARP updates the ARP cache for future reference
and then sends the packet to the MAC address that replied.
To define an ARP supported configuration on a controller or service platform:
1Select
Devices from the Configuration tab.
The Device Configuration screen displays a list of managed devices or peer controllers, service platforms or

5.2.8.3 Overriding a Profile’s L2TPV3 Configuration
Overriding a Profile’s Network Configuration
L2TP V3 is a standard used for transporting different types of layer 2 frames in an IP network (and Access Point
profile). L2TP V3 defines control and encapsulation protocols for tunneling layer 2 frames between two IP nodes.
Use L2TP V3 to create tunnels for transporting layer 2 frames. L2TP V3 enables controllers, service platforms and
Access Points to create tunnels for transporting Ethernet frames to and from bridge VLANs and physical ports.
L2TP V3 tunnels can be defined between WING devices and other vendor devices supporting the L2TP V3
protocol.
Multiple pseudowires can be created within an L2TP V3 tunnel. WING supported access points support an Ethernet
VLAN pseudowire type exclusively.
Ethernet VLAN pseudowires transport Ethernet frames to and from a specified VLAN. One or more L2TP V3
tunnels can be defined between tunnel end points. Each tunnel can have one or more L2TP V3 sessions. Each
tunnel session corresponds to one pseudowire. An L2TP V3 control connection (a L2TP V3 tunnel) needs to be
established between the tunneling entities before creating a session.
For optimal pseudowire operation, both the L2TP V3 session originator and responder need to know the
psuedowire type and identifier. These two parameters are communicated during L2TP V3 session establishment.
An L2TP V3 session created within an L2TP V3 connection also specifies multiplexing parameters for identifying a
pseudowire type and ID.
The working status of a pseudowire is reflected by the state of the L2TP V3 session. If a L2TP V3 session is down,
the pseudowire associated with it must be shut down. The L2TP V3 control connection keep-alive mechanism can
serve as a monitoring mechanism for the pseudowires associated with a control connection.
To define an L2TPV3 configuration for an Access Point profile:
1Select
Devices from the Configuration tab.
The Device Configuration screen displays a list of managed devices or peer controllers, service platforms or
Access Points.
2 Select a target device (by double-clicking it) from amongst those displayed within the Device Configuration

4Expand the Network menu and select L2TPv3.
NOTE: A pseudowire is an emulation of a layer 2 point-to-point connection over a
packet-switching network (PSN). A pseudowire was developed out of the necessity
to encapsulate and tunnel layer 2 protocols across a layer 3 network.
NOTE: If connecting an Ethernet port to another Ethernet port, the pseudowire
type must be Ethernet port, if connecting an Ethernet VLAN to another Ethernet
VLAN, the pseudowire type must be Ethernet VLAN.

Critical Resource Specifies the critical resource that should exist for a tunnel between two
peers. Critical resources are device IP addresses or interface destinations
interopreted as critical to the health of the network. Critical resources
allow for the continuous monitoring of these defined addresses. A critical
resource, if not available, can result in the network suffering performance
degradation. A critical resource can be a gateway, AAA server, WAN
interface or any hardware or service on which the stability of the network
depends. Critical resources are pinged regularly. If there’s a connectivity
issue, an event is generated stating a critical resource is unavailable.
Peer IP Address Specifies the IP address of the tunnel destination peer device.
Hostname Specifies the administrator assigned hostname of the tunnel.
Name Enter a 31 character maximum session name. There is no idle timeout for
a tunnel. A tunnel is not usable without a session and a subsequent
session name.The tunnel is closed when the last session tunnel session is

5.2.8.4 Overriding a Profile’s GRE Configuration
Overriding a Profile’s Network Configuration
Generic routing encapsulation (GRE) tunneling can be configured to bridge Ethernet packets between WLANs and
a remote WLAN gateway over a GRE tunnel. The tunneling of 802.3 packets using GRE is an alternative to MiNT or
L2TPv3. Related features like ACLs for extended VLANs are still available using layer 2 tunneling over GRE.
Using GRE, Access Points map one or more VLANs to a tunnel. The remote endpoint is a user-configured WLAN
gateway IP address, with an optional secondary IP address should connectivity to the primary GRE peer be lost.
VLAN traffic is expected in both directions in the GRE tunnel. A WLAN mapped to these VLANs can be either
open or secure. Secure WLANs require authentication to a remote RADIUS server available within your
deployment using standard RADIUS protocols. Access Points can reach both the GRE peer as well as the RADIUS.
Previous releases supported only IPv4 tunnel end points, now support for both IPv4 or IPv6 tunnel endpoints is
available. However, a tunnel needs to contain either IPv4 or IPv6 formatted device addresses and cannot be mixed.
With the new IPv6 tunnel implementation, all outbound packets are encapsulated with the GRE header, then the
IPv6 header. The header source IP address is the local address of the IPv6 address of tunnel interface, and the
destination address peer address of the tunnel. All inbound packets are de-capsulated by removing the IPv6 and
GRE header before sending it over to the IP stack.
To define a profile’s GRE settings:

Select + Add Row to populate the table with a maximum of two peer configurations.
10 Define the following Peer parameters:
Tag Native VLAN Select this option to tag the native VLAN. The IEEE 802.1Q specification is
supported for tagging frames and coordinating VLANs between devices.
IEEE 802.1Q adds four bytes to each frame identifying the VLAN ID for
upstream devices that the frame belongs. If the upstream Ethernet device
does not support IEEE 802.1Q tagging, it does not interpret the tagged
frames. When VLAN tagging is required between devices, both devices
must support tagging and be configured to accept tagged VLANs. When
a frame is tagged, the 12 bit frame VLAN ID is added to the 802.1Q header
so upstream Ethernet devices know which VLAN ID the frame belongs to.
The device reads the 12 bit VLAN ID and forwards the frame to the
appropriate VLAN. When a frame is received with no 802.1Q header, the
upstream device classifies the frame using the default or native VLAN
assigned to the Trunk port. The native VLAN allows an Ethernet device to
associate untagged frames to a VLAN when no 802.1Q frame is included
in the frame. This feature is disabled by default.
MTU Set an IPv4 tunnel’s maximum transmission unit (MTU) from 128 - 1,476.
The MTU is the largest physical packet size (in bytes) transmittable within
the tunnel. Any messages larger than the MTU are divided into smaller
packets before being sent. A larger MTU provides greater efficiency
because each packet carries more user data while protocol overheads,
such as headers or underlying per-packet delays, remain fixed; the
resulting higher efficiency means a slight improvement in bulk protocol
throughput. A larger MTU results in the processing of fewer packets for
the same amount of data. For IPv4, the overhead is 24 bytes (20 bytes
IPv4 header + 4 bytes GRE Header), thus the default setting for an IPv4
MTU is 1,476.
MTU6 Set an IPv6 tunnel’s MTU from 128 - 1,456. The MTU is the largest physical
packet size (in bytes) transmit able within the tunnel. Any messages
larger than the MTU are divided into smaller packets before being sent. A
larger MTU provides greater efficiency because each packet carries more
user data while protocol overheads, such as headers or underlying per-
packet delays, remain fixed; the resulting higher efficiency means a slight
improvement in bulk protocol throughput. A larger MTU results in the
processing of fewer packets for the same amount of data. For IPv6, the
overhead is 44 bytes (40 bytes IPv6 header + 4 bytes GRE header), thus
the default setting for an IPv6 MTU is 1,456.

Peer IP Address Define the IP address of the added GRE peer to serve as a network
address identifier. Designate whether the IP is formatted as an IPv4 or
IPv6 address. IPv4 is a connectionless protocol for packet switched
networking. IPv4 operates as a best effort delivery method, as it does not
guarantee delivery, and does not ensure proper sequencing or duplicate
delivery (unlike TCP). IPv4 hosts can use link local addressing to provide
local connectivity. IPv6 is the latest revision of the Internet Protocol (IP)
designed to replace IPv4. IPV6 provides enhanced identification and
location information for computers on networks routing traffic across the
Internet. IPv6 addresses are eight groups of four hexadecimal digits
separated by colons.
Criteria Specify the establishment criteria for creating a GRE tunnel. In a multi-
controller within a RF domain, it’s always the master node with which the
tunnel is established. The tunnel is only created if the tunnel device is
designated one of the following:
vrrp-master
cluster-master
rf-domain-manager
The tunnel is automatically created if Always (default setting) is selected.
This indicates the device need not be any one of the above three (3) to
establish a tunnel.
VRRP Group Set the VRRP group ID only enabled when the Establishment Criteria is
set to vrrp-master. A virtual router redundancy group (VRRP) enables the
creation of a group of routers as a default gateway for redundancy.
Clients can point to the IP address of the VRRP virtual router as their
default gateway and utilize a different group member if a master
becomes unavailable.

Enable Fast leave
processing
Select this option to remove a Layer 2 LAN interface from the IGMP
snooping forwarding table entry without initially sending IGMP group-
specific queries to the interface. When receiving a group-specific
IGMPv2 leave message, IGMP snooping removes the interface from the
Layer 2 forwarding table entry for that multicast group, unless a
multicast router was learned on the port. Fast-leave processing
enhances bandwidth management for all hosts on the network.
Enable IGMP Querier Select this option to enable IGMP querier. IGMP snoop querier is used to
keep host memberships alive. It’s primarily used in a network where
there’s a multicast streaming server and hosts subscribed to the server
and no IGMP querier present. An IGMP querier sends out periodic IGMP
query packets. Interested hosts reply with an IGMP report packet. IGMP
snooping is only conducted on wireless radios. IGMP multicast packets
are flooded on wired ports. IGMP multicast packet are not flooded on
the wired port. IGMP membership is also learnt on it and only if present,
then it is forwarded on that port.
IGMP Version Use the spinner control to set the IGMP version compatibility to either
version 1, 2 or 3. IGMPv1 is defined by RFC 1112, IGMPv2 is defined by
RFC 2236 and IGMPv3 defined by RFC 4604 which defines both IGMPv3
and MLDv2. IGMPv2 improves over IGMPv1 by adding the ability for a
host to signal desire to leave a multicast group. IGMPv3 improves over
IGMPv2 by adding the ability to listen to multicast traffic originating
from a set of source IP addresses exclusively. The default setting is 3.
IGMP Query Interval Set the interval IGMP queries are made. Options include Seconds
(1 - 18,000), Minutes (1 - 300) and Hours (1 - 5). The default setting is

5.2.8.6 Overriding a Profile’s MLD Snooping Configuration
Overriding a Profile’s Network Configuration
Multicast Listener Discovery (MLD) snooping enables a controller, service platform or Access Point to examine MLD
packets and make forwarding decisions based on content. MLD is used by IPv6 devices to discover devices
wanting to receive multicast packets destined for specific multicast addresses. MLD uses multicast listener queries
and multicast listener reports to identify which multicast addresses have listeners and join multicast groups.
MLD snooping caps the flooding of IPv6 multicast traffic on controller, service platform or Access Point VLANs.
When enabled, MLD messages are examined between hosts and multicast routers and to discern which hosts are
receiving multicast group traffic. The controller, service platform or Access Point then forwards multicast traffic
only to those interfaces connected to interested receivers instead of flooding traffic to all interfaces.

5.2.8.7 Overriding a Profile’s Quality of Service (QoS) Configuration
Overriding a Profile’s Network Configuration
The controller or service platform use different Quality of Service (QoS) screens to define WLAN and device radio
QoS and traffic shaping configurations for profiles.
Traffic shaping regulates network data transfers to ensure a specific performance level. Traffic shaping delays the
flow of packets defined as less important than prioritized traffic streams. Traffic shaping enables traffic control out
an interface to match its flow to the speed of a remote target’s interface and ensure traffic conforms applied
policies. Traffic can be shaped to meet downstream requirements and eliminate network congestion when data
rates are in conflict.
QoS values are required to provide priority of service to some packets over others. For example, VoIP packets get
higher priority than data packets to provide a better quality of service for high priority voice traffic.
The profile QoS screen maps the 6-bit Differentiated Service Code Point (DSCP) code points to the older 3-bit IP
Precedent field located in the Type of Service byte of an IP header. DSCP is a protocol for specifying and
controlling network traffic by class so that certain traffic types get precedence. DSCP specifies a specific per-hop
behavior that is applied to a packet. This QoS assignment can be overridden as needed, but removes the device
configuration from the profile that may be shared with other similar device models.
To define an QoS configuration:
Enable MLD Querier Select the option to enable MLD querier on the controller, service platform
or Access Point. When enabled, the device sends query messages to
discover which network devices are members of a given multicast group.
This setting is disabled by default.
MLD Version Define whether MLD version 1 or 2 is utilized as the MLD querier. MLD
version 1 is based on IGMP version 2 for IPv4. MLD version 2 is based on
IGMP version 3 for IPv4 and is fully backward compatible. IPv6 multicast
uses MLD version 2. The default MLD version is 2.
MLD Query Interval Set the interval in which query messages are sent to discover device
multicast group memberships. Set an interval in either Seconds (1 -
18,000), Minutes (1 - 300) or Hours (1 - 5). The default interval is 1 minute.
MLD Robustness
Variable
Set a MLD IGMP robustness value (1 - 7) used by the sender of a query.
The MLD robustness variable enables refinements to account for expected
packet loss on a subnet. Increasing the robust count allows for more
packet loss, but increases the leave latency of the subnetwork unless the
value is zero. The default variable is 2.
Maximum Response
Time
Specify the maximum response time (from 1 - 25,000 milliseconds) before
sending a responding report. Queriers use MLD reports to join and leave
multicast groups and receive group traffic. The default setting is 10
milliseconds.
Other Querier time

layer address, rejects packets addressed to the IP associated with the
virtual router and accepts packets addressed to the IP associated with the
virtual router. The solitary cluster master is the cluster member elected,
using a priority assignment scheme, to provide management
configuration and Smart RF data to other cluster members. Cluster
requests go through the elected master before dissemination to other
cluster members. The RF Domain manager is the elected member
capable of storing and provisioning configuration and firmware images
for other members of the RF Domain.
VRRP Group Set the VRRP group ID from 1 - 255. VRRP groups is only enabled when
the Establishment Criteria is set to vrrp-master.
Class Index Set a class index from 1 - 4.
Max Buffers Se the Max Buffers to specify the queue length limit after which the
queue starts to drop packets. Set the maximum queue lengths for
packets. The upper length is 400 for Access Points.
RED Level Set the packet queue length for RED. The upper limit is 400 for Access
Points. The rate limiter uses the random early detection (RED) algorithm
for rate limiting traffic. RED is a queueing technique for congestion
avoidance. RED monitors the average queue size and drops or marks
packets. If the buffer is near empty, all incoming packets are accepted.
When the queue grows, the probability for dropping an incoming packet
also grows. When the buffer is full, the probability has reached 1 and all
incoming packets are dropped.
RED Percent Set a percentage (1 - 100) for RED rate limiting at a percentage of
maximum buffers.

5.2.8.8 Overriding a Profile’s Spanning Tree Configuration
Overriding a Profile’s Network Configuration
The Multiple Spanning Tree Protocol (MSTP) provides an extension to RSTP to optimize the usefulness of VLANs.
MSTP allows for a separate spanning tree for each VLAN group, and blocks all but one of the possible alternate
paths within each spanning tree topology.
If there’s just one VLAN in the Access Point managed network, a single spanning tree works fine. However, if the
network contains more than one VLAN, the network topology defined by single STP would work, but it’s possible
to make better use of the alternate paths available by using an alternate spanning tree for different VLANs or
groups of VLANs.
A MSTP supported deployment uses multiple MST regions with multiple MST instances (MSTI). Multiple regions and
other STP bridges are interconnected using one single common spanning tree (CST).
MSTP includes all of its spanning tree information in a single Bridge Protocol Data Unit (BPDU) format. BPDUs are
used to exchange information bridge IDs and root path costs. Not only does this reduce the number of BPDUs
required to communicate spanning tree information for each VLAN, but it also ensures backward compatibility
with RSTP. MSTP encodes additional region information after the standard RSTP BPDU as well as a number of
MSTI messages. Each MSTI messages conveys spanning tree information for each instance. Each instance can be
assigned a number of configured VLANs. The frames assigned to these VLANs operate in this spanning tree
instance whenever they are inside the MST region. To avoid conveying their entire VLAN to spanning tree mapping
in each BPDU, the Access Point encodes an MD5 digest of their VLAN to an instance table in the MSTP BPDU. This
digest is used by other MSTP supported devices to determine if the neighboring device is in the same MST region
as itself.
Traffic Class Devices that originate a packet must identify different classes or priorities
for IPv6 packets. Devices use the traffic class field in the IPv6 header to
set this priority.
802.1p Priority Assign a 802.1p priority as a 3-bit IPv6 precedence value in the Type of
Service field of the IPv6 header used to set the priority. The valid values
for this field are 0-7. Up to 64 entries are permitted. The priority values
are:
0 – Best Effort
1 – Background
2 – Spare
3 – Excellent Effort
4 – Controlled Load
5 – Video
6 – Voice

5.2.8.9 Overriding a Profile’s Routing Configuration
Overriding a Profile’s Network Configuration
Routing is the process of selecting IP paths within the wireless network to route traffic. Use the Routing screen to
set Destination IP and Gateway addresses enabling the assignment of static IP addresses for requesting clients
without creating numerous host pools with manual bindings. This eliminates the need for a long configuration file
and reduces the resource space required to maintain address pools.
Both IPv4 and IPv6 routes are separately configurable using their appropriate tabs. For IPv6 networks, routing is
the part of IPv6 that provides forwarding between hosts located on separate segments within a larger IPv6
network where IPv6 routers provide packet forwarding for other IPv6 hosts.

7 Use the drop-down menu to select a Policy Based Routing policy. If a suitable policy is not available, select the
Create icon or modify an existing policy-based routing policy by selecting the Edit icon.
Policy-based routing (PBR) is a means of expressing and forwarding (routing) data packets based on policies
defined by administrators. PBR provides a flexible mechanism for routing packets through routers,
complementing existing routing protocols. PBR is applied to incoming packets. Packets received on an
interface with PBR enabled are considered are passed through enhanced packet filters (route maps). Based on
the route maps, packets are forwarded/routed to their next hop.
Refer to the Static Routes table to set Destination IP and Gateway addresses enabling the assignment of static
IP addresses to requesting clients (without creating numerous host pools with manual bindings).
• Add IP addresses and network masks in the Network Address column.
•Provide the Gateway address used to route traffic.
• Provide an IP address for the Default Gateway used to route traffic.
Note, when routing packets, the controller, by default, obtains Default Gateway and Name Servers IP addresses
from the DHCP server policy. If manually configuring the Default Gateway for static routing, also configure the
Name Server’s IP address in the controller’s device/profile config contexts. For more information on using the
GUI to configure Name Servers, see Overriding a Profile’s DNS Configuration. If using the CLI, in the device/
profile context, execute the following command: ip name-server <NAME-SERVER-IP-ADDRESS>.

5.2.8.10 Overriding a Profile’s Dynamic Routing (OSPF) Configuration
Overriding a Profile’s Network Configuration
Open Shortest Path First (OSPF) is a link-state interior gateway protocol (IGP). OSPF routes IP packets within a
single routing domain (autonomous system), like an enterprise LAN. OSPF gathers link state information from
neighbor routers and constructs a network topology. The topology determines the routing table presented to the
Internet Layer which makes routing decisions based solely on the destination IP address found in IP packets.
OSPF detects changes in the topology, like a link failure, and plots a new loop-free routing structure. It computes
the shortest path for each route using a shortest path first algorithm. Link state data is maintained on each router
and is periodically updated on all OSPF member routers.
OSPF uses a route table managed by the link cost (external metrics) defined for each routing interface. The cost
could be the distance of a router (round-trip time), link throughput or link availability. Setting a cost value provides
a dynamic way to load balancing traffic between routes of equal cost.
An OSPF network can be subdivided into routing areas to simplify administration and optimize traffic utilization.
Areas are logical groupings of hosts and networks, including routers having interfaces connected to an included
network. Each area maintains a separate link state database whose information may be summarized towards the
rest of the network by the connecting router. Areas are identified by 32-bit IDs, expressed either in decimal, or
octet-based dot-decimal notation. Areas can defined as:
stub area - A stub area is an area which does not receive route advertisements external to the autonomous system
(AS) and routing from within the area is based entirely on a default route.
totally-stub - A totally stubby area does not allow summary routes and external routes. A default route is the only
way to route traffic outside of the area. When there’s only one route out of the area, fewer routing decisions are
needed, lowering system resource utilization.
non-stub - A non-stub area imports autonomous system external routes and send them to other areas. However. it
still cannot receive external routes from other areas.
nssa - NSSA is an extension of a stub that allows the injection of limited external routes into a stub area. If
selecting NSSA, no external routes, except a default route, enter the area.
totally nssa - Totally nssa is an NSSA using 3 and 4 summary routes are not flooded into this type of area. It is also
possible to declare an area both totally stubby and not-so-stubby, which means that the area will receive only the
default route from area 0.0.0.0, but can also contain an autonomous system boundary router (ASBR) that accepts
external routing information and injects it into the local area, and from the local area into area 0.0.0.0.
A router running OSPF sends hello packets to discover neighbors and elect a designated router. The hello packet
includes link state information and list of neighbors. OSPF is savvy with layer 2 topologies. If on a point-to-point
Gateway Set the IPv6 route gateway. A network gateway in IPv6 is the same as
in IPv4. A gateway address designates how traffic is routed out of the
current subnet.

Maximum
Transmission Unit
(MTU)
Set the PPPoE client maximum transmission unit (MTU) from 500 - 1,492.
The MTU is the largest physical packet size in bytes a network can
transmit. Any messages larger than the MTU are divided into smaller
packets before being sent. A PPPoE client should be able to maintain its
point-to-point connection for this defined MTU size. The default MTU is
1,492.
IPv6 MTU Set an IPv6 MTU for this virtual interface from 1,280 - 1,500. A larger MTU
provides greater efficiency because each packet carries more user data
while protocol overheads, such as headers or underlying per-packet
delays, remain fixed; the resulting higher efficiency means a slight
improvement in bulk protocol throughput. A larger MTU results in the
processing of fewer packets for the same amount of data. The default is
1,500.

5.2.8.11 Overriding a Profile’s Border Gateway Protocol (BGP) Configuration
Overriding a Profile’s Network Configuration
Border Gateway Protocol (BGP) is an inter-ISP routing protocol which establishes routing between ISPs. ISPs use
BGP to exchange routing and reachability information between Autonomous Systems (AS) on the Internet. BGP
makes routing decisions based on paths, network policies and/or rules configured by network administrators. The
primary role of a BGP system is to exchange network reachability information with other BGP peers. This
information includes information on AS that the reachability information traverses. This information is sufficient to
create a graph of AS connectivity from which routing decisions can be created and rules enforced.
An Autonomous System (AS) is a set of routers under the same administration that use Interior Gateway Protocol
(IGP) and common metrics to define how to route packets within the AS. AS uses inter-AS routing to route
packets to other ASs. For an external AS, an AS appears to have a single coherent interior routing plan and
presents a consistent picture of the destinations reachable through it.
Routing information exchanged through BGP supports only destination based forwarding (it assumes a router
forwards packets based on the destination address carried in the IP header of the packet).
BGP uses TCP as its transport protocol. This eliminates the need to implement explicit update fragmentation,
retransmission, acknowledgement, and sequencing. BGP listens on TCP port 179. The error notification mechanism
used in BGP assumes that TCP supports a graceful close (all outstanding data is delivered before the connection is
closed).
To define or override a profile’s BGP configuration:
1Select
Devices from the Configuration tab.
The Device Configuration screen displays a list of managed devices or peer controllers, service platforms or
Access Points.
2 Select a target device (by double-clicking it) from amongst those displayed within the Device Configuration

and common metrics to define how to route packets. Select a value from
1 - 4,294,967,295.
Enable Enable to start BGP on this controller or service platform. BGP is only
supported on RFS4000, RFS6000and NX9500 model controllers and
service platforms. The default is disabled.
Always Compare Med Multi-exit Discriminator (MED) is a value used by BGP peers to select the
best route among multiple routes. When enabled, the MED value
encoded in the route is always compared when selecting the best route
to the host network. A route with a lower MED value is always selected
over a route with a higher MED value. BGP does not discriminate
between iBGP and eBGP when using MED for route selection. This option
is mutually exclusive to the Deterministic MED option.
Default IPv4 Unicast Select this option to enable IPv4 unicast traffic for neighbors. This option
is disabled by default.

7 Optionally select the Missing AS Worst option to treat any path that does not contain a MED value as the least
preferable route. This setting is disabled by default.
8 Review the following Bestpath parameters:
9 Set or override the following Distance for Route Types. The distance parameter is a rating of route
trustworthiness. The greater the distance, the lower the trust rating. The distance can be set for each type of
route indicating its trust rating.
Deterministic Med Multi-exit Discriminator (MED) is used by BGP peers to select the best
route among multiple routes. When enabled, MED route values (from the
same AS) are compared to select the best route. This best route is then
compared with other routes in the BGP route table to select the best
overall route. This option is mutually exclusive to the Always Compare
MED option.
Enforce First AS Select this option to deny any updates received from an external
neighbor that does not have the neighbor’s configured AS at the
beginning of the received AS path parameter. This enhances security by
not allowing traffic from an unauthorized AS. This setting is disabled by
default.
Fast External Failover Select this option to immediately reset the BGP session on the interface
once the BGP connection goes down. Normally, when a BGP connection
goes down, the device waits for the expiry of the duration specified in
Holdtime parameter before bringing down the interface. This setting is
enabled by default.
Log Neighbor

consistency in advertisements. This setting is disabled by default.
Router ID Select this option to manually configure the router ID for this BGP
supported controller or service platform. The router ID identifies the
device uniquely. When no router ID is specified, the IP address of the
interface is considered the router ID. This setting is disabled by default.
Scan Time Select this option to set the scanning interval for updating BGP routes.
This interval is the period between two consecutive scans the BGP
device checks for the validity of routes in its routing table. To disable this
setting, set the value to Zero (0). The default setting is 60 seconds.
AS-Path Ignore Select this option to prevent an AS path from being considered as a
criteria for selecting a preferred route. The route selection algorithm uses
the AS path as one of the criteria when selecting the best route. When
this option is enabled, the AS path is ignored.
Compare Router Id Select this option to use the router ID as a selection criteria when
determining a preferred route. The route selection algorithm uses various
criteria when selecting the best route. When this option is enabled, the
router ID is used to select the best path between two identical BGP

peers. By filtering updates, ORF minimizes update generation and
exchange overhead.
The local BGP device advertises ORF in the send mode. The peer BGP
device receives the ORF capability in receive mode. The two devices
exchange updates to maintain the ORF for each router. Only a peer
group or an individual BGP router can be configured to be in receive or
send mode. A member of a peer group cannot be configured.

Advertisement
Interval
Use the Advertisement Interval to set the minimum interval between
sending BGP router updates. Sending too many router updates creates
flapping of routes leading to possible disruptions. Set a minimum interval
so that the BGP routing updates are sent after the set interval in
seconds. The default is 5 seconds.
Disable Capability
Negotiate
Select to disable capability negotiation with BGP neighbors. This is to
allow compatibility with older BGP versions that have no capability
parameters used in the open messages between peers. This setting id
disabled by default.

networks. Select to enforce neighbors to perform multi-hop check. This
setting is disabled by default.
Next Hop Self Select to enable Next Hop Self. Use this to configure this device as the
next hop for a BGP speaking neighbor or peer group. This allows the
BGP device to change the next hop information that is sent to iBGP
peers. The next hop address is set to the IP address of the interface used
to communicate with the eBGP neighbor. This setting is disabled by
default.
Override Capability Select this to enable the ability to override capability negotiation result.
This setting is disabled by default.
Passive Select this option to set this BGP neighbor as passive. When a neighbor
is set as passive, the local device should not attempt to open a
connection to this device. This setting is disabled by default
Reconnect Interval Set a reconnection interval for peer BGP devices from 0 - 65,535
seconds. The default setting is 120 seconds.
Send Community Select this option to ensure the community attribute is sent to the BGP
neighbor. The community attribute groups destinations in a certain
community and applies routing decisions based on the community. On
receiving community attribute, the BGP router announces it to the
neighbor.
Shutdown Select this option to administratively shutdown this BGP neighbor. This
setting is disabled by default.
Soft Reconfiguration
Inbound
Select this option to store updates for inbound soft reconfiguration. Soft-
reconfiguration can be used in lieu of BGP route refresh capability.
Selecting this option enables local storage of all received routes and their
attributes. This requires additional memory on the BGP device.
When a soft reset (inbound) is performed on the neighbor device, the
locally stored routes are reprocessed according to the inbound policy.
The BGP neighbor connection is not affected.

Update Source Select this option to allow internal BGP sessions to use any operational
interface for TCP connections. Use Update Source in conjunction with
any specified interface on the router. The loopback interface is the
interface that is most commonly used with this command. The use of
loopback interface eliminates a dependency and BGP does not have to
rely on the availability of a particular interface for making TCP
connections. This setting is disabled by default.
Unsuppress Map Enable Unsuppress Map to selectively advertise more precise routing
information to this neighbor. Use this in conjunction with the Route
Aggregate command.
The route aggregate command creates a route map with a IP/mask

5.2.8.13 Overriding a Profile’s Bridge VLAN Configuration
Overriding a Profile’s Network Configuration
A Virtual LAN (VLAN) is separately administrated virtual network within the same physical managed network.
VLANs are broadcast domains defined within switches to allow control of broadcast, multicast, unicast, and
unknown unicast within a Layer 2 device.
Administrators often need to route traffic to interoperate between different VLANs. Bridging VLANs are only for
non-routable traffic, like tagged VLAN frames destined to some other device which will untag it. When a data
frame is received on a port, the VLAN bridge determines the associated VLAN based on the port of reception.
Using forwarding database information, the Bridge VLAN forwards the data frame on the appropriate port(s).
VLAN's are useful to set separate networks to isolate some computers from others, without actually having to have
separate cabling and Ethernet switches. Controllers and service platforms can do this on their own, without need
for the computer or other gear to know itself what VLAN it's on (this is called port-based VLAN, since it's assigned
by port of the switch). Another common use is to put specialized devices like VoIP Phones on a separate network
for easier configuration, administration, security, or quality of service.
Two main VLAN bridging modes are available:
•Tunnel Mode: In tunnel mode, the traffic at the Access Point is always forwarded through the best path. The
Access Point decides the best path to use and appropriately forwards packets. Setting the VLAN to tunnel
mode ensures packets are Bridge packets between local Ethernet ports, any local radios, and tunnels to other
APs and wireless controller.
•Local Mode: Local mode is typically configured in remote branch offices where traffic on remote private LAN
segment needs to be bridged locally. Local mode implies that the wired and the wireless traffic are to be
bridged locally.
To define a bridge VLAN configuration or override for a device profile:
1Select
Devices from the Configuration tab.
The Device Configuration screen displays a list of managed devices or peer controllers, service platforms or
Access Points.
2 Select a target device (by double-clicking it) from amongst those displayed within the Device Configuration

VLAN Lists the numerical identifier defined for the Bridge VLAN when it was
initially created. The available range is from 1 - 495. This value cannot be
modified during the edit process.
Description Lists a VLAN description assigned when the VLAN was created or
modified. The description should be unique to the VLAN’s specific
configuration and help differentiate it from other VLANs with similar
configurations.
Edge VLAN Mode Defines whether the VLAN is currently in edge VLAN mode. A green
check mark defines the VLAN as extended. An edge VLAN is the VLAN
where hosts are connected. For example, if VLAN 10 is defined with
wireless clients, and VLAN 20 is where the default gateway resides,
VLAN 10 should be marked as an edge VLAN and VLAN 20 shouldn’t be
marked as an edge VLAN. When defining a VLAN as edge VLAN, the
firewall enforces additional checks on hosts in that VLAN. For example, a
host cannot move from an edge VLAN to another VLAN and still keep
firewall flows active.
Trust ARP Responses Trusted ARP packets are used to update the IP-MAC Table to prevent IP
spoof and arp-cache poisoning attacks. When ARP trust is enabled, a
green check mark displays. When disabled, a red “X” displays.
Trust DHCP Responses When enabled, DHCP packets from a DHCP server are trusted and
permissible. DHCP packets update the DHCP Snoop Table to prevent IP
spoof attacks. When DHCP trust is enabled, a green check mark
displays. When disabled, a red “X” displays.

IPv6 Firewall Lists whether IPv6 is enabled on this bridge VLAN. A green checkmark
defines this setting as enabled. A red X defines this setting as disabled.
IPV6 provides enhanced identification and location information for
computers on networks routing traffic across the Internet. IPv6
addresses are composed of eight groups of four hexadecimal digits
separated by colons. IPv6 hosts can configure themselves automatically
when connected to an IPv6 network using the neighbor discovery
protocol via ICMPv6 router discovery messages. When first connected to
a network, a host sends a link-local router solicitation multicast request
for its configuration parameters; routers respond to such a request with
a router advertisement packet that contains Internet Layer configuration
parameters.
DHCPv6 Trust Lists whether DHCPv6 responses are trusted on this bridge VLAN. A
green checkmark defines this setting as enabled. A red X defines this
setting as disabled. If enabled, only DHCPv6 responses are trusted and
forwarded over the bridge VLAN.
RA Guard Lists whether router advertisements (RA) are allowed on this bridge
VLAN. A green checkmark defines this setting as enabled. A red X
defines this setting as disabled. RAs are periodically sent to hosts or
sent in response to solicitation requests. The advertisement includes
IPv6 prefixes and other subnet and host information.

Select this option to remove a Layer 2 LAN interface from the IGMP
snooping forwarding table entry without initially sending IGMP group-
specific queries to the interface. When receiving a group specific
IGMPv2 leave message, IGMP snooping removes the interface from the
Layer 2 forwarding table entry for that multicast group, unless a
multicast router was learned on the port. Fast-leave processing
enhances bandwidth management for all hosts on the network. This
setting is disabled by default.

Multicast Router Learn
Mode
Set the pim-dvmrp or static multicast routing learn mode. DVMRP
builds a parent-child database using a constrained multicast model to
build a forwarding tree rooted at the source of the multicast packets.
Multicast packets are initially flooded down this source tree. If
redundant paths are on the source tree, packets are not forwarded
along those paths.
Enable IGMP Querier Select this option to enable IGMP querier. IGMP snoop querier is used to
keep host memberships alive. It’s primarily used in a network where
there’s a multicast streaming server and hosts subscribed to the server
and no IGMP querier present. An IGMP querier sends out periodic IGMP
query packets. Interested hosts reply with an IGMP report packet. IGMP
snooping is only conducted on wireless radios. IGMP multicast packets
are flooded on wired ports. IGMP multicast packet are not flooded on
the wired port. IGMP membership is also learnt on it and only if present,
then it is forwarded on that port.
Source IP Address If enabling IGMP querier, set the source IP address used for IGMP
snooping over a multicast router.
IGMP Version Use the spinner control to set the IGMP version compatibility to either
version 1, 2 or 3. IGMPv1 is defined by RFC 1112, IGMPv2 is defined by
RFC 2236 and IGMPv3 defined by RFC 4604 which defines both
IGMPv3 and MLDv2. IGMPv2 improves over IGMPv1 by adding the ability
for a host to signal desire to leave a multicast group. IGMPv3 improves
over IGMPv2 by adding the ability to listen to multicast traffic
originating from a set of source IP addresses exclusively.
Maximum Response
Time
Specify the maximum interval (from 1 - 25 seconds) before sending a
responding report. When no reports are received from a radio, radio
information is removed from the snooping table. The controller or
service platform only forwards multicast packets to radios present in the
snooping table. For IGMP reports from wired ports, the controller or
service platform forwards these reports to the multicast router ports.
The default setting is 1 seconds.

26 Define the following General MLD snooping parameters for the bridge VLAN configuration:
Multicast Listener Discovery (MLD) snooping enables a controller, service platform or Access Point to examine
MLD packets and make forwarding decisions based on content. MLD is used by IPv6 devices to discover
devices wanting to receive multicast packets destined for specific multicast addresses. MLD uses multicast
listener queries and multicast listener reports to identify which multicast addresses have listeners and join
multicast groups.
MLD snooping caps the flooding of IPv6 multicast traffic on controller, service platform or Access Point VLANs.
When enabled, MLD messages are examined between hosts and multicast routers and to discern which hosts
are receiving multicast group traffic. The controller, service platform or Access Point then forwards multicast
traffic only to those interfaces connected to interested receivers instead of flooding traffic to all interfaces.
Enable MLD Snooping Enable MLD snooping to examine MLD packets and support content

5.2.8.17 Overriding a Profile’s Network Alias Configuration
Overriding a Profile’s Network Configuration
With large deployments, the configuration of remote sites utilizes a set of shared attributes, of which a small set of
attributes are unique for each location. For such deployments, maintaining separate configuration (WLANs,
profiles, policies and ACLs) for each remote site is complex. Migrating any global change to a particular
configuration item to all the remote sites is a complex and time consuming operation.
Also, this practice does not scale gracefully for quick growing deployments.
An alias enables an administrator to define a configuration item, such as a hostname, as an alias once and use the
defined alias across different configuration items such as multiple ACLs.
Once a configuration item, such as an ACL, is utilized across remote locations, the Alias used in the configuration
item (ACL) is modified to meet local deployment requirement. Any other ACL or other configuration items using
the modified alias also get modified, simplifying maintenance at the remote deployment.
Aliases have scope depending on where the Alias is defined. Alias are defined with the following scopes:
•Global aliases are defined from the Configuration > Network > Alias screen. Global aliases are available for use
globally across all devices, profiles and RF Domains in the system.
•Profiles aliases are defined from the Configuration > Devices > System Profile > Network > Alias screen. Profile
aliases are available for use to a specific group of wireless controllers or Access Points. Alias values defined in a
profile override the alias values defined within global aliases.
•RF Domain aliases are defined from the Configuration > Devices > RF Domain > Alias screen. RF Domain aliases
are available for use for a site as a RF Domain is site specific. RF Domain alias values override alias values
defined in a global alias or a profile alias configuration.
•Device aliases are defined from the Configuration > Devices > Device Overrides > Network > Alias screen.
Device aliases are utilized by a singular device only. Device alias values override global, profile or RF Domain
alias configurations.
Using an alias, configuration changes made at a remote location override any updates at the management center.
For example, if an network alias defines a network range as 192.168.10.0/24 for the entire network, and at a remote
deployment location, the local network range is 172.16.10.0/24, the network alias can be overridden at the
deployment location to suit the local requirement. For the remote deployment location, the network alias work

with the 172.16.10.0/24 network. Existing ACLs using this network alias need not be modified and will work with the
local network for the deployment location. This simplifies ACL definition and management while taking care of
specific local deployment requirements.

5.2.8.17.1 Basic Alias
A basic alias is a set of configurations consisting of VLAN, Host, Network and Address Range alias configurations.
A VLAN alias is a configuration for optimal VLAN re-use and management for local and remote deployments. A
host alias configuration is for a particular host device’s IP address. A network alias configuration is utilized for an IP
address on a particular network. An address range alias is a configuration for a range of IP addresses.

Use the VLAN Alias field to create unique aliases for VLANs that can be utilized at different deployments. For
example, if a VLAN ID is set as 10 for the central network, and the VLAN is set as 26 at a remote location, the
VLAN can be overridden at the remote location using an alias. At the remote location, the network is functional
with an ID of 26, but utilizes the name defined at the central local network. A new VLAN need not be created

Use the String Alias field to create aliases for hosts that can be utilized at different deployments. For example,
if the main domain at a remote location is called loc1.domain.com and at another deployment location it is
called loc2.domain.com, the alias can be overridden at the remote location to suit the local (but remote)
requirement. At one remote location, the alias functions with the loc1.domain.com domain and at the other with
the loc2.domain.com domain.
9Select
+ Add Row to define Host Alias settings:
Use the Host Alias field to create aliases for hosts that can be utilized at different deployments. For example, if
a central network DNS server is set a static IP address, and a remote location’s local DNS server is defined, this
host can be overridden at the remote location. At the remote location, the network is functional with a local
DNS server, but uses the name set at the central network. A new host need not be created at the remote
location. This simplifies creating and managing hosts and allows an administrator to better manage specific
local requirements.
10 Select + Add Row to define Network Alias settings:
Use the Network Alias field to create aliases for IP networks that can be utilized at different deployments. For

5.2.8.18 Overriding a Profile’s IPv6 Neighbor Configuration
Overriding a Profile’s Network Configuration
IPv6 neighbor discovery uses ICMP messages and solicited multicast addresses to find the link layer address of a
neighbor on the same local network, verify the neighbor’s reachability and track neighboring devices.
Upon receiving a neighbor solicitation message, the destination replies with neighbor advertisement (NA). The
source address in the NA is the IPv6 address of the device sending the NA message. The destination address in
the neighbor advertisement message is the IPv6 address of the device sending the neighbor solicitation. The data
portion of the NA includes the link layer address of the node sending the neighbor advertisement.
Neighbor solicitation messages also verify the availability of a neighbor once its the link layer address is identified.
When a node wants to verify the reachability of a neighbor, the destination address in a neighbor solicitation
message is the unicast address of the neighbor.
A neighbor is interpreted as reachable when an acknowledgment is returned indicating packets have been
received and processed. If packets are reaching the device, they’re also reaching the next hop neighbor, providing
a confirmation the next hop is reachable.

5.2.9.1 Overriding a Profile’s General Security Settings
Overriding a Profile’s Security Configuration
A profile can leverage existing firewall, wireless client role and WIPS policies and apply them to the profile’s
configuration. This affords each profile a truly unique combination of data protection policies best meeting the
IPv6 Address Provide a static IPv6 IP address for neighbor discovery. IPv6 hosts can
configure themselves automatically when connected to an IPv6 network
using the Neighbor Discovery Protocol via Internet Control Message
Protocol version 6 (ICMPv6) router discovery messages. When first
connected to a network, a host sends a link-local router solicitation
multicast request for its configuration parameters; routers respond to
such a request with a router advertisement packet that contains Internet
Layer configuration parameters. IPv6 addresses are composed of eight
groups of four hexadecimal digits separated by colons.
MAC Address Enter the hardware encoded MAC addresses of up to 256 IPv6 neighbor
devices. A neighbor is interpreted as reachable when an
acknowledgment is returned indicating packets have been received and
processed. If packets are reaching the device, they’re also reaching the
next hop neighbor, providing a confirmation the next hop is reachable.
Switch VLAN Interface Use the spinner control to set the virtual interface (from 1 - 4094) used
for neighbor advertisements and solicitation messages.
Device Type Specify the device type for this neighbor solicitation is for. Options
include Host, Router and DHCP Server. The default setting is Host.

5.2.9.2 Overriding a Profile’s Certificate Revocation List (CRL) Configuration
Overriding a Profile’s Security Configuration
A certificate revocation list (CRL) is a list of revoked certificates that are no longer valid. A certificate can be
revoked if the certificate authority (CA) had improperly issued a certificate, or if a private-key is compromised. The
most common reason for revocation is the user no longer being in sole possession of the private key.
To define a Certificate Revocation configuration or override:
Firewall Policy Use the drop-down menu to select an existing Firewall Policy to use as
an additional security mechanism with this profile. All devices using this
profile must meet the requirements of the firewall policy to access the
network. A firewall is a mechanism enforcing access control, and is
considered a first line of defense in protecting proprietary information
within the network. The means by which this is accomplished varies, but
in principle, a firewall can be thought of as mechanisms both blocking
and permitting data traffic within the network. If an existing Firewall
policy does not meet your requirements, select the Create icon to create
a new firewall policy that can be applied to this profile. An existing
policy can also be selected and edited as needed using the Edit icon.
Wireless Client Role
Policy
Use the drop-down menu to select a client role policy used to
strategically filter client connections based on a pre-defined set of filter
rules and connection criteria. If an existing Wireless Client Role policy
does not meet your requirements, select the Create icon to create a new
configuration that can be applied to this profile. An existing policy can
also be selected and edited as needed using the Edit icon.
WEP Shared Key
Authentication
Select this option to require devices to use a WEP key to access the
network using this profile. The controller or service platform use the key
algorithm to convert an ASCII string to the same hexadecimal number.
Clients without adapters need to use WEP keys manually configured as
hexadecimal numbers. This option is disabled by default.
Client Identity Group Select the client identity group to apply to this device profile. Client
identity is a set of unique fingerprints used to identify a class of devices.
A Client identity group is a set of client attributes that identify devices
and apply specific permissions and restrictions on them.The information
is used to configure permissions and access rules for that device class
and can assist administrators by applying permissions and rules to
multiple devices simultaneously.
CMP Policy Use the drop down-menu to assign a CMP policy to allow a device to
communicate to a CMP supported CA server, initiate a certificate
request and download the required certificates from the CA server. CMP
supports multiple request options through for device communicating to
a CMP supported CA server. The device can initiate a request for getting
the certificates from the server. It can also auto update the certificates
which are about to expire.

5.2.9.4 Overriding a Profile’s VPN Configuration
Overriding a Profile’s Security Configuration
IPSec VPN provides a secure tunnel between two networked peer devices. Administrators can define which
packets are sent within the tunnel, and how they’re protected. When a tunnelled peer sees a sensitive packet, it
creates a secure tunnel and sends the packet through the tunnel to its remote peer destination.
Tunnels are sets of security associations (SA) between two peers. SAs define the protocols and algorithms applied
to sensitive packets and specify the keying mechanisms used by tunneled peers. SAs are unidirectional and exist in
both the inbound and outbound direction. SAs are established per the rules and conditions of defined security
protocols (AH or ESP).
Use crypto maps to configure IPSec VPN SAs. Crypto maps combine the elements comprising IPSec SAs. Crypto
maps also include transform sets. A transform set is a combination of security protocols, algorithms and other
settings applied to IPSec protected traffic. One crypto map is utilized for each IPSec peer, however for remote VPN
deployments one crypto map is used for all the remote IPSec peers.
Internet Key Exchange (IKE) protocol is a key management protocol standard used in conjunction with IPSec. IKE
enhances IPSec by providing additional features, flexibility, and configuration simplicity for the IPSec standard. IKE
automatically negotiates IPSec SAs, and enables secure communications without time consuming manual pre-
configuration.

Overriding a Profile’s Security Configuration
Network Address Translation (NAT) is a technique to modify network address information within IP packet headers
in transit. This enables mapping one IP address to another to protect wireless controller managed network address
credentials. With typical deployments, NAT is used as an IP masquerading technique to hide private IP addresses
behind a single, public facing, IP address.
Additionally, NAT is a process of modifying network address information in IP packet headers while in transit
across a traffic routing device for the purpose of remapping one IP address to another. In most deployments NAT
is used in conjunction with IP masquerading which hides RFC1918 private IP addresses behind a single public IP
address.
NAT can provide a profile outbound Internet access to wired and wireless hosts connected to either an Access
Point or a wireless controller. Many-to-one NAT is the most common NAT technique for outbound Internet access.

Static NAT creates a permanent, one-to-one mapping between an address on an internal network and a
perimeter or external network. To share a Web server on a perimeter interface with the Internet, use static
address translation to map the actual address to a registered IP address. Static address translation hides the
actual address of the server from users on insecure interfaces. Casual access by unauthorized users becomes
much more difficult. Static NAT requires a dedicated address on the outside network for each host.
Name If adding a new NAT policy, provide a name to help distinguish it from
others with similar configurations. The length cannot exceed 64
characters.
IP Address Range Define a range of IP addresses that are hidden from the public Internet.
NAT modifies network address information in the defined IP range while
in transit across a traffic routing device. NAT only provides IP address
translation and does not provide a firewall. A branch deployment with
NAT by itself will not block traffic from being potentially routed through
a NAT device. Consequently, NAT should be deployed with a stateful
firewall.

16 Select OK to save the changes or overrides made to the static NAT configuration. Select Reset to revert to the
last saved configuration.
17 Select the Dynamic NAT tab.
Dynamic NAT configurations translate the IP address of packets going out from one interface to another
interface based on configured conditions. Dynamic NAT requires packets be switched through a NAT router to
generate translations in the translation table.
Protocol Select the protocol for use with static translation (TCP, UDP and Any
are available options). TCP is a transport layer protocol used by
applications requiring guaranteed delivery. It’s a sliding window
protocol handling both time outs and retransmissions. TCP establishes
a full duplex virtual connection between two endpoints. Each endpoint
is defined by an IP address and a TCP port number. The User Datagram
Protocol (UDP) offers only a minimal transport service, non-guaranteed
datagram delivery, and provides applications direct access to the
datagram service of the IP layer. UDP is used by applications not
requiring the level of service of TCP, or are using communications
services (multicast or broadcast delivery) not available from TCP. The
default setting is Any.
Destination IP Enter the local address used at the (source) end of the static NAT
configuration. This address (once translated) is not exposed to the
outside world when the translation address is used to interact with the
remote destination.
Destination Port Use the spinner control to set the local port number used at the
(source) end of the static NAT configuration. The default value is port 1.
NAT IP Enter the IP address of the matching packet to the specified value. The
IP address modified can be either source or destination based on the
direction specified.
NAT Port Enter the port number of the matching packet to the specified value.
This option is valid only if the direction specified is destination.
Network Select Inside or Outside NAT as the network direction. Inside is the
default setting.

5.2.9.7 Overriding a Profile’s Bridge NAT Configuration
Overriding a Profile’s Security Configuration
Use Bridge NAT to manage Internet traffic originating at a remote site. In addition to traditional NAT functionality,
Bridge NAT provides a means of configuring NAT for bridged traffic through an access point. NAT rules are applied
to bridged traffic through the access point, and matching packets are NATed to the WAN link instead of being
bridged on their way to the router.
Using Bridge NAT, a tunneled VLAN (extended VLAN) is created between the NoC and a remote location. When a
remote client needs to access the Internet, Internet traffic is routed to the NoC, and from there routed to the
Internet. This increases the access time for the end user on the client.
To resolve latency issues, Bridge NAT identifies and segregates traffic heading towards the NoC and outwards
towards the Internet. Traffic towards the NoC is allowed over the secure tunnel. Traffic towards the Internet is
switched to a local WLAN link with access to the Internet.
To define a NAT configuration or override that can be applied to a profile:

5.2.9.9 Overriding a Profile’s VRRP Configuration
Profile Overrides
A default gateway is a critical resource for connectivity. However, it’s prone to a single point of failure. Thus,
redundancy for the default gateway is required by the access point. If WAN backhaul is available, and a router
failure occurs, then the Access Point should act as a router and forward traffic on to its WAN link.
Define an external Virtual Router Redundancy Protocol (VRRP) configuration when router redundancy is required
in a wireless network requiring high availability.
The election of a VRRP master is central to the configuration of VRRP. A VRRP master (once elected) performs the
following functions:
• Responds to ARP requests
• Forwards packets with a destination link layer MAC address equal to the virtual router MAC address
• Rejects packets addressed to the IP address associated with the virtual router, if it is not the IP address owner
• Accepts packets addressed to the IP address associated with the virtual router, if it is the IP address owner or
accept mode is true.
Nodes losing the election process enter a backup state where they monitor the master for any failures, and in case
of a failure, one of the backups become the master and assumes the management of the designated virtual IPs. A
backup does not respond to an ARP request, and discards packets destined for a virtual IP resource.
To define the configuration of a VRRP group:
1Select
Devices from the Configuration tab.
The Device Configuration screen displays a list of managed devices or peer controllers, service platforms or
Access Points.

5.2.9.10 Overriding a Profile’s Critical Resource Configuration
Profile Overrides
Critical resources are device IP addresses or destinations interopreted as critical to the health of the network. The
critical resource feature allows for the continuous monitoring of these defined addresses. A critical resource, if not
available, can result in the network suffering performance degradation. A critical resource can be a gateway, AAA
server, WAN interface or any hardware or service on which the stability of the network depends. Critical resources
are pinged regularly. If there’s a connectivity issue, an event is generated stating a critical resource is unavailable.
By default, there’s no enabled critical resource policy and one needs to be created and implemented.
Critical resources can be monitored directly through the interfaces on which they’re discovered. For example, a
critical resource on the same subnet as the access point can be monitored by its IP address. However, a critical
resource located on a VLAN must continue to monitored on that VLAN.
Preempt Select this option to ensure a high priority backup router is available to preempt a
lower priority backup router resource. The default setting is enabled. When
selected, the Preempt Delay option becomes enabled to set the actual delay
interval for pre-emption. This setting determines if a node with a higher priority
can take over all the Virtual IPs from the nodes with a lower priority.
Preempt Delay If the Preempt option is selected, use the spinner control to set the delay interval
(in seconds) for pre-emption.
Interface Select this value to enable/disable VRRP operation and define the VLAN (1 -
4,094) interface where VRRP will be running. These are the interfaces monitored
to detect a link failure.
Sync Group Select the option to assign a VRRP sync group to this VRRP ID’s group of virtual
IP addresses. This triggers VRRP fail over if an advertisement is not received from
the virtual masters that are part of this VRRP sync group. This setting is disabled
b y default.
Network Monitoring:
Local Interface
Select wwan1, pppoe1 and VLAN ID(s) as needed to extend VRRP monitoring to
these local Access Point interfaces. Once selected, these interfaces can be
assigned an increasing or decreasing level or priority for virtual routing within the
VRRP group.
Network Monitoring:
Critical Resource
Assign the priority level for the selected local interfaces. Backup virtual routers
can increase or decrease their priority in case the critical resources connected to
the master router fail, and then transition to the master state themselves.
Additionally, the master virtual router can lower its priority if the critical resources
connected to it fails, so the backup can transition to the master state. This value
can only be set on the backup or master router resource, not both. Options
include None, increment-priority, decrement priority.

A captive portal is an access policy for providing guests temporary and restrictive access to the wireless
network.
A captive portal configuration provides secure authenticated controller or service platform access using a
standard Web browser. Hotspots provides authenticated access by capturing and re-directing a wireless user's
Web browser session to a captive portal login page where the user must enter valid credentials to access to
the wireless network. Once logged into the captive portal additional Agreement, Welcome and Fail pages
provide the administrator with a number of options on the hotspot’s screen flow and user appearance.
Either select an existing captive portal policy, use the default captive portal policy or select the Create link to
create a new configuration that can be applied to this profile. For more information, see Configuring Captive
Portal Policies on page 11-1.

6Use the RADIUS Server Application Policy drop-down menu to select an application policy to authenticate users
and authorize access to the network. A RADIUS policy provides the centralized management of authentication
data (usernames and passwords). When an client attempts to associate, the controller or service platform sends
the authentication request to the RADIUS server.
If an existing RADIUS server policy does not meet your requirements, select the Create link to create a new
policy.
7Use the DHCP Server Policy drop-down menu assign this profile a DHCP server policy. If an existing DHCP
policy does not meet the profile’s requirements, select the Create icon to create a new policy configuration that
can be applied to this profile or the Edit icon to modify the parameters of an existing DHCP Server policy.
Dynamic Host Configuration Protocol (DHCP) allows hosts on an IP network to request and be assigned IP
addresses as well as discover information about the network where they reside. Each subnet can be configured
with its own address pool. Whenever a DHCP client requests an IP address, the DHCP server assigns an IP
address from that subnet’s address pool. When the onboard DHCP server allocates an address for a DHCP
client, the client is assigned a lease, which expires after an pre-determined interval. Before a lease expires,
wireless clients (to which leases are assigned) are expected to renew them to continue to use the addresses.
Once the lease expires, the client is no longer permitted to use the leased IP address. The profile’s DHCP server
policy ensures all IP addresses are unique, and no IP address is assigned to a second client while the first
client's assignment is valid (its lease has not expired).
8Use the DHCPv6 Server Policy drop-down menu assign this profile a DHCPv6 server policy. If an existing DHCP
policy for IPv6 does not meet the profile’s requirements, select the Create icon to create a new policy
configuration that can be applied to this profile or the Edit icon to modify the parameters of an existing DHCP
Server policy.
DHCPv6 is a networking protocol for configuring IPv6 hosts with IP addresses, IP prefixes or other
configuration attributes required on an IPv6 network. DHCP in IPv6 works in with IPv6 router discovery. With
the proper RA flags, DHCPv6 works like DHCP for IPv4. The central difference is the way a device identifies
itself if assigning addresses manually instead of selecting addresses dynamically from a pool.
For more information, see Configuring a Captive Portal Policy on page 11-2.
9Use the Guest Management Policy drop-down menu to select an existing Guest Management policy to use as a
mechanism to manage guest users with this profile.
10 Use the RADIUS Server Policy drop-down menu to select an existing RADIUS server policy to use as a user
validation security mechanism with this profile.
A profile can have its own unique RADIUS server policy to authenticate users and authorize access to the
network. A profile’s RADIUS policy provides the centralized management of controller or service platform
authentication data (usernames and passwords). When an client attempts to associate, an authentication
request is sent to the RADIUS server.For more information, see Configuring RADIUS Server Policies on page 11-
57.

resolution. Bonjour locates devices such as printers, other computers and services that these computers offer
over a local network.
Bonjour provides a general method to discover services on a local area network (LAN). It allows users to set up
a network without any configuration. Services such as printers, scanners and file-sharing servers can be found
using Bonjour. Bonjour only works within a single broadcast domain. However, with special DNS configuration,
it can be extended to find services across broadcast domains.

5.2.9.12 Overriding a Profile’s Management Configuration
Profile Overrides
Controllers and service platforms have mechanisms to allow/deny management access to the network for separate
interfaces and protocols (HTTP, HTTPS, Telnet, SSH or SNMP). These management access configurations can be
applied strategically to profiles as resource permissions dictate. Additionally, overrides can be applied to customize
a device’s management configuration, if deployment requirements change an a devices configuration must be
modified from its original device profile configuration.
Additionally, an administrator can define a profile with unique configuration file and device firmware upgrade
support. In a clustered environment, these operations can be performed on one controller or service platform, then
propagated to each member of the cluster and onwards to devices managed by each cluster member.
To define or override a profile’s management configuration:
1Select
Devices from the Configuration tab.
The Device Configuration screen displays a list of devices or peer controllers, service platforms or Access
Points.
2 Select a target device (by double-clicking it) from amongst those displayed within the Device Configuration
screen.

• Disable A-MPDU Aggregation if the intended vehicular speed is greater than 30 mph. For more information, see
Radio Override Configuration.
• Set a misconfiguration recovery time for the non-root AP profile. This configuration should delay the rejection
of the newest configuration push from the controller, potentially causing adoption loss.
The additional delay is to support cases when the new configuration from the controller causes the root AP to
move from current channel to other channels, resulting in a mesh link going down, and in turn non-root APs
losing adoption. This delay accommodates the time needed for the non-root AP to scan all channels and
finding the best root node. The non-root AP can begin operating on the new channel, and establish the mesh
link re-adopt to the controller. (For countries using DFS, the scan time is also factored in for the configured
value). If the AP fails to find a suitable root node within this time, this new config is a misconfigured and the
device would reject the latest config.
For outdoor APs, it is recommended the misconfiguration-recovery-time be disabled. This can be accomplished
by setting the value to 0. Update non root ap71xx profiles on the controller to include this change.
Using an appropriate console terminal and or connection to your device log on to the CLI and follow these
steps:

5.2.9.15.9 Advanced MiNT Protocol Configuration
Overriding a Profile’s Advanced Configuration
MINT provides the means to secure profile communications at the transport layer. Using MINT, a device can be
configured to only communicate with other authorized (MINT enabled) devices. Keys can also be generated
externally using any application (like openssl). These keys must be present on the device managing the domain for
key signing to be integrated with the UI. A device needing to communicate with another first negotiates a security
context with that device.
The security context contains the transient keys used for encryption and authentication. A secure network requires
users to know about certificates and PKI. However, administrators do not need to define security parameters for
Access Points to be adopted (secure WISPe being an exception, but that isn’t a commonly used feature). Also,
users can replace any device on the network or move devices around and they continue to work. Default security
parameters for MiNT are such that these scenarios continue to function as expected, with minimal user
intervention required only when a new network is deployed

Excessive traffic can cause performance issues on an extended VLAN. Excessive traffic can be caused by
numerous sources including network loops, faulty devices or malicious software such as a worm or virus that
has infected on one or more devices. Rate limiting reduces the maximum rate sent or received per wireless
client. It prevents any single user from overwhelming the wireless network. It can also provide differential
service for service providers. Uplink and downlink rate limits are usually configured on a RADIUS server using
vendor specific attributes. Rate limits are extracted from the RADIUS server’s response. When such attributes
are not present, the settings defined on the controller, service platform or Access Point are applied. An
administrator can set separate QoS rate limit configurations for data types transmitted from the network
(upstream) and data transmitted from a wireless clients back to associated radios (downstream).

Refer to the advanced profile’s Miscellaneous menu item to set or override a profile’s NAS configuration. The
profile database on the RADIUS server consists of user profiles for each connected network access server (NAS)
port. Each profile is matched to a username representing a physical port. When the wireless controller authorizes

Miscellaneous from the Advanced menu item.
Max Burst Size Use the spinner to set the maximum burst size from 0 - 1024 kb. The smaller the
burst, the less likely the upstream packet transmission will result in congestion for
the WLAN’s client destinations. By trending the typical number of ARP, broadcast,
multicast and unknown unicast packets over a period of time, the average rate for
each access category can be obtained. Once a baseline is obtained, administrators
should add a 10% margin (minimally) to allow for traffic bursts. The default burst
size is 320 kbytes.
Background Configures the random early detection threshold (as a percentage) for low priority
background traffic. Background packets are dropped and a log message
generated if the rate exceeds the set value. Background traffic consumes the least
bandwidth of any access category, so this value can be set to a lower value once a
general upstream rate is known by the network administrator (using a time trend
analysis). The default setting
is 50%.
Best-Effort Configures the random early detection threshold (as a percentage) for low priority
best-effort traffic. Best-effort packets are dropped and a log message generated if
the rate exceeds the set value. Best effort traffic consumes little bandwidth, so
this value can be set to a lower value once a general upstream rate is known by
the network administrator (using a time trend analysis).The default setting is 50%.
Video Configures the random early detection threshold (as a percentage) for high
priority video traffic. Video packets are dropped and a log message generated if
the rate exceeds the set value. Video traffic consumes significant bandwidth, so
this value can be set to a higher value once a general upstream rate is known by
the network administrator (using a time trend analysis).The default setting is 25%.
Voice Configures the random early detection threshold (as a percentage) for high
priority voice traffic. Voice packets are dropped and a log message generated if
the rate exceeds the set value. Voice applications consume significant bandwidth,

5.3 Auto Provisioning Policies
Device Configuration
Wireless devices can adopt other wireless devices. For example, a wireless controller can adopt an number of
Access Points. When a device is adopted, the device configuration is determined by the adopting device. Since
multiple configuration policies are supported, an adopting device needs to determine which configuration policies
should be used for a given adoptee. Auto Provisioning Policies determine which configuration policies are used for
an adoptee based on some of its properties. For example, a configuration policy could be assigned based on MAC
address, IP address, CDP snoop strings, etc.
Once created an auto provisioning policy can be used in profiles or device configuration objects. An auto
provisioning policy contains a set of ordered by precedence rules that either deny or allow adoption based on
potential adoptee properties and a catch-all variable that determines if the adoption should be allowed when none
of the rules is matched. All rules (both deny and allow) are evaluated sequentially starting with the rule with the
lowest precedence. The evaluation stops as soon as a rule has been matched, no attempt is made to find a better
match further down in the set.
The evaluation is performed using various matching criteria. The matching criteria supported include:
NOTE: Enabling Bluetooth detection results in interference on the Access Point’s
2.4 GHz radio when in WLAN mode. WLANs are susceptible to sources of
interference by Bluetooth devices.
MAC Matches the MAC address of a device attempting to be adopted. Either a single
MAC address or a range of MAC addresses can be specified.
VLAN Matches when adoption over a Layer 2 link matches the VLAN ID of an adoption
request. Note that this is a VLAN ID as seen by the recipient of the request, in
case of multiple hops over different VLANs this may different from VLAN ID set
by the sender. A single VLAN ID is specified in the rule. This rule is ignored for
adoption attempts over Layer 3.
IP Address Matches when adoption is using a Layer 3 link matches the source IP address of
an adoption request. In case of NAT the IP address may be different from what
the sender has used. A single IP, IP range or IP/mask is specified in the rule. This
rule is ignored for adoption attempts over Layer 2.
Serial Number Matches exact serial number (case insensitive).
Model Matches exact model name (case insensitive).
Device Configuration
Wireless Controller and Service Platform System Reference Guide 5 - 269
Auto Provisioning is the process to discover controllers or service platforms available in the network, pick the most
desirable controller or service platform, establish an association, optionally obtain an image upgrade and obtain its
configuration.
At adoption, an Access Point solicits and receives multiple adoption responses from controllers and service
platforms available on the network. These adoption responses contain loading policy information the Access Point
uses to select the optimum controller or service platform for adoption. By default, an auto provisioning policy
generally distributes AP adoption evenly amongst available controller or service platform. Modify existing adoption
policies or create a new one as needed to meet the adoption requirements of a device and their assigned profile.
An auto provisioning policy enables an administrator to define adoption rules an Access Point’s adoption by a
wireless controller.
Auto provisioning policies set the different restrictions on how an Access Point gets adopted to a wireless
controller.
To review existing Auto Provisioning Policy configurations:
1Select
Configuration > Devices > Auto Provisioning Policy.
2The
Auto-Provisioning screen displays by default.
DHCP Option Matches the value found in DHCP vendor option 191 (case insensitive). DHCP
vendor option 191 can be setup to communicate various configuration parameters
to an AP. The value of the option in a string in the form of tag=value separated by
a semicolon, e.g.’tag1=value1;tag2=value2;tag3=value3’. The access point includes
the value of tag’rf-domain’, if present. This value is matched against the auto
provisioning policy.
FQDN Matches a substring to the FQDN of a device (case insensitive).
CDP Matches a substring in a list of CDP snoop strings (case insensitive). For example,
if an Access Point snooped 3 devices: controller1.extremenetworks.com,
controller2.extremenetworks.com and
controller3.extremenetworks.com,’controller1’,’extremenetworks’,
’extremenetworks.com’, are examples of the substrings that will match.
LLDP Matches a substring in a list of LLDP snoop strings (case insensitive). For
example, if an Access Point snooped 3 devices: controller1.extremenetworks.com,
controller2.extremenetworks.com and
controller3.extremenetworks.com,’controller1’, ’extremenetworks’,
’extremenetworks.com’, are substrings match.
NOTE: A device configuration does not need to be present for an auto provisioning
policy to take effect. Once adopted, and the device’s configuration is defined and
applied by the controller or service platform, the auto provisioning policy mapping
does not have impact on subsequent adoptions by the same device.

Event Policies enable an administrator to create specific notification mechanisms using one, some or all of the
SNMP, syslog, forwarding or e-mail notification options available to the controller or service platform. Each listed
event can have customized notification settings defined and saved as part of an event policy. Thus, policies can be
configured and administrated in respect to specific sets of client association, authentication/encryption and
performance events. Once policies are defined, they can be mapped to device profiles strategically as the
likelihood of an event applies to particular devices. By default, there’s no enabled event policy and one needs to be
created and implemented.
When initially displayed, the Event Policy screen lists interfaces. Existing policies can have their event notification
configurations modified as device profile requirements warrant.

Wireless Configuration
A Wireless Local Area Network (WLAN) is a data-communications system and wireless local area network that
flexibly extends the functionalities of a wired LAN. A WLAN links two or more computers or devices using spread-
spectrum or OFDM modulation based technology. A WLAN does not require lining up devices for line-of-sight
transmission, and are thus, desirable for wireless networking. Roaming users can be handed off from one wireless
controller connected Access Point to another, like a cellular phone system. WLANs can therefore be configured
around the needs of specific user groups, even when they are not in physical proximity.
WLANs can be used to provide an abundance of services, including data communications (allowing mobile devices
to access applications), E-mail, file and print services or even specialty applications (such as guest access control
and asset tracking).
Each wireless controller WLAN configuration contains encryption, authentication and QoS policies and conditions
for user connections. Connected Access Point radios transmit periodic beacons for each BSS. A beacon advertises
the SSID, security requirements, supported data rates of the wireless network to enable clients to locate and
connect to the WLAN.
WLANs are mapped to radios on each connected Access Point. A WLAN can be advertised from a single Access
Point radio or can span multiple Access Points and radios. WLAN configurations can be defined to only provided
service to specific areas of a site. For example a guest access WLAN may only be mapped to a 2.4GHz radio in a
lobby or conference room providing limited coverage while a data WLAN is mapped to all 2.4GHz and 5GHz radios
at the branch site providing complete coverage.
RFS4000 and RFS6000 series wireless controllers support a maximum of 32 WLANs. The NX7500 service
platforms support up to 256 WLANs. NX9000 series service platforms support up to 1000 WLANs.
The wireless configuration is comprised the following policies:
•Wireless LAN Policy
•Configuring WLAN QoS Policies
•Radio QoS Policy
•Association ACL
•Smart RF Policy
•MeshConnex Policy
•Mesh QoS Policy
•Passpoint Policy
•Sensor Policy
These policies can be separately selected within the Configuration > Wireless pane located in top, left-hand, side of
the UI.

WLANs. NX9000 series service platforms support up to 1000 WLANs.
SSID Displays the name of the SSID assigned to the WLAN when created or
last modified. Optionally, select a WLAN and click the Edit button to
update the WLAN’s SSID.
Description Displays the brief description set for each listed WLAN when it was
either created or modified.
WLAN Status Lists each WLAN’s current status as either Active or Shutdown. A
green check mark defines the WLAN as available to clients on all
radios where it has been mapped. A red “X” defines the WLAN as
shutdown, meaning even if the WLAN is mapped to radios, it’s not
available for clients to associate.
VLAN Pool Lists each WLAN’s current VLAN mapping. The wireless controller
permits mapping a WLAN to more than one VLANs. When a client
associates with a WLAN, the client is assigned a VLAN by load balance
distribution. The VLAN is picked from a pool assigned to the WLAN.
Keep in mind however, typical deployments only map a single VLAN to
a WLAN. The use of a pool is strictly optional.
Bridging Mode Displays the bridging mode used by each WLAN. Available bridging
modes are Local and Tunnel.
DHCP Option 82 DHCP Option 82 is commonly used in large enterprise deployments to
provide client physical attachment information. Option 82 is used in
distributed DHCP server/relay environments, where relays insert
additional information to identify the client’s point of attachment. A
red “X” defines DHCP option 82 as disabled, a green check means its
enabled.
DHCPv6 LDRA Lightweight DHCPv6 Relay Agent (LDRA) is used to insert relay-agent
options in DHCPv6 message exchanges that identify client-facing
interfaces. These relay agents are deployed to forward DHCPv6
messages between clients and servers when they are not on the same
IPv6 link. A red “X” indicates this WLAN acts as a DHCPv6 LDRA.
Authentication Type Displays the name of the authentication scheme this WLAN is using to
secure its client membership transmissions. None is listed if
authentication is not used within this WLAN. Refer to the Encryption
type column if no authentication is used to verify there is some sort of
data protection used with the WLAN or risk no protection at all.
Encryption Type Displays the name of the encryption scheme this WLAN is using to
secure its client membership transmissions. None is listed if encryption
is not used within this WLAN. Refer to the Authentication type column
if no encryption is used to verify there is some sort of data protection
used with the WLAN or risk using this WLAN with no protection at all.
QoS Policy Lists the QoS policy applied to each listed WLAN. A QoS policy needs
to be custom selected (or created) for each WLAN in respect to the
WLAN’s intended client traffic and the voice, video or normal data
traffic it supports.

schemes.
Wireless Configuration
Wireless Controller and Service Platform System Reference Guide 6 - 8
Figure 6-4 WLAN Policy Security screen
Authentication ensures only known and trusted users or devices access a WLAN. Authentication is enabled per
WLAN to verify the identity of both users and devices. Authentication is a challenge and response procedure for
validating user credentials such as username, password and sometimes secret-key information.
A client must authenticate to an Access Point to receive resources from the network. Controllers and service
platforms support EAP, EAP PSK, EAP-MAC, MAC and PSK/None authentication options.
Refer to the following to configure an authentication scheme for a WLAN:
Wireless Configuration
Wireless Controller and Service Platform System Reference Guide 6 - 9
•802.1x EAP, EAP-PSK and EAP MAC
•MAC Authentication
•PSK / None
Secure guest access to the network is referred to as captive portal access. A captive portal is guest access policy
for providing guests temporary and restrictive access to the wireless network. Existing captive portal policies can
be applied to a WLAN to provide secure guest access as needed.
A captive portal configuration provides secure authenticated access using a standard Web browser. Captive portals
provide authenticated access by capturing and re-directing a wireless user's Web browser session to a captive
portal login page where the user must enter valid credentials to access to the network. Once logged into captive
portal, additional Agreement, Welcome and Fail pages provide the administrator with a number of options on
captive portal screen flow and user appearance. Refer to Captive Portal on page 6-13 for information on assigning
a captive portal policy to a WLAN.
A passpoint policy provides an interoperable platform for streamlining Wi-Fi access to Access Points deployed as
public hotspots. Passpoint is supported across a wide range of wireless network deployment scenarios and client
devices. For more information, see Passpoint Policy.
Encryption is central for WLAN security, as it provides data privacy for traffic forwarded over a WLAN. When the
802.11 specification was introduced, Wired Equivalent Privacy (WEP) was the primary encryption mechanism. WEP
has since been interpreted as flawed in many ways, and is not considered an effective standalone encryption
scheme for securing a wireless controller WLAN. WEP is typically used WLAN deployments designed to support
legacy clients. New device deployments should use either WPA or WPA2 encryption.
Encryption applies a specific algorithm to alter its appearance and prevent unauthorized hacking. Decryption
applies the algorithm in reverse, to restore the data to its original form. A sender and receiver must employ the
same encryption/decryption method to interoperate. When both TKIP and CCMP are both enabled a mix of clients
are allowed to associate with the WLAN. Some use TKIP, others use CCMP. Since broadcast traffic needs to be
understood by all clients, the broadcast encryption type in this scenario is TKIP.
TKIP-CCMP, WPA2-CCMP, WEP 64, WEP 128 and Keyguard encryption options are supported.
Refer to the following to configure an encryption scheme for a WLAN:
•TKIP-CCMP
•WPA2-CCMP

6.1.2.1 802.1x EAP, EAP-PSK and EAP MAC
Configuring WLAN Security
The Extensible Authentication Protocol (EAP) is the de-facto standard authentication method used to provide
secure authenticated access to WLANs. EAP provides mutual authentication, secured credential exchange,
dynamic keying and strong encryption. 802.1X EAP can be deployed with WEP, WPA or WPA2 encryption schemes
to further protect user information forwarded over WLANs.
The EAP process begins when an unauthenticated supplicant (client device) tries to connect with an authenticator
(in this case, the authentication server). An Access Point passes EAP packets from the client to an authentication
Wireless Configuration
Wireless Controller and Service Platform System Reference Guide 6 - 10
server on the wired side of the Access Point. All other packet types are blocked until the authentication server
(typically, a RADIUS server) verifies the client’s identity.
802.1X EAP provides mutual authentication over the WLAN during authentication. The 802.1X EAP process uses
credential verification to apply specific policies and restrictions to WLAN users to ensure access is only provided to
specific wireless controller resources.
802.1X requires a 802.1X capable RADIUS server to authenticate users and a 802.1X client installed on each devices
accessing the EAP supported WLAN. An 802.1X client is included with most commercial operating systems,
including Microsoft Windows, Linux and Apple OS X.
The RADIUS server authenticating 802.1X EAP users can reside either internally or externally to a controller, service
platform or Access Point. User account creation and maintenance can be provided centrally using ADSP or
individually maintained on each device. If an external RADIUS server is used, EAP authentication requests are
forwarded.
When using PSK with EAP, the controller, service platform or Access Point sends a packet requesting a secure link
using a pre-shared key. The authenticating device must use the same authenticating algorithm and passcode
during authentication. EAP-PSK is useful when transitioning from a PSK network to one that supports EAP. The
only encryption types supported with this are TKIP, CCMP and TKIP-CCMP.

EAP, EAP-PSK and EAP MAC Deployment Considerations
802.1x EAP, EAP-PSK and EAP MAC
Before defining a 802.1x EAP, EAP-PSK or EAP MAC supported configuration on a WLAN, refer to the following
deployment guidelines to ensure the configuration is optimally effective:
• A valid certificate should be issued and installed on devices providing 802.1X EAP. The certificate should be
issued from an Enterprise or public certificate authority to allow 802.1X clients to validate the identity of the
authentication server prior to forwarding credentials.
• If using an external RADIUS server for EAP authentication, the round trip delay over the WAN should not
exceed 150ms. Excessive delays over a WAN can cause authentication and roaming issues and impact wireless
client performance. If experiencing excessive delays, consider using local RADIUS resources.
6.1.2.2 MAC Authentication
Configuring WLAN Security
MAC is a device level authentication method used to augment other security schemes when legacy devices are
deployed using static WEP.
MAC authentication can be used for device level authentication by permitting WLAN access based on device MAC
address. MAC authentication is typically used to augment WLAN security options that do not use authentication
(such as static WEP, WPA-PSK and WPA2-PSK) MAC authentication can also be used to assign VLAN
memberships, Firewall policies and time and date restrictions.
MAC authentication can only identify devices, not users. MAC authentication only references a client wireless
interface card MAC address when authenticating the device, it does not distinguish the device’s user credentials.
MAC authentication is somewhat poor as a standalone data protection technique, as MAC addresses can be easily
spoofed by hackers who can provide a device MAC address to mimic a trusted device within the network.
MAC authentication is enabled per WLAN profile, augmented with the use of a RADIUS server to authenticate
each device. A device’s MAC address can be authenticated against the local RADIUS server built into the device or
centrally (from a datacenter). For RADIUS server compatibility, the format of the MAC address can be forwarded
to the RADIUS server in non-delimited and or delimited formats:
To configure MAC on a WLAN:

Configuration > Wireless > Wireless LAN Policy to display available WLANs.

MAC Authentication
Before defining a MAC authentication configuration on a WLAN, refer to the following deployment guidelines to

6.1.2.8 TKIP-CCMP
Configuring WLAN Security
CCMP is a security standard used by the Advanced Encryption Standard (AES). AES serves the same function TKIP
does for WPA-TKIP. CCMP computes a Message Integrity Check (MIC) using the proven Cipher Block Chaining
(CBC) technique. Changing just one bit in a message produces a totally different result.
The encryption method is Temporal Key Integrity Protocol (TKIP). TKIP addresses WEP’s weaknesses with a re-
keying mechanism, a per-packet mixing function, a message integrity check and an extended initialization vector.
However TKIP also has vulnerabilities.
To configure TKIP-CCMP encryption on a WLAN:
1Select
Configuration > Wireless > Wireless LAN Policy to display available WLANs.
2 Select the Add button to create an additional WLAN or select an existing WLAN and Edit to modify its
properties.

Unicast messages are addressed to a single device on the network. Broadcast messages are addressed to
multiple devices. When using WPA2, a wireless client can use 2 keys, one unicast key, for its own traffic to and
from an Access Point, and one broadcast key, the common key for all the clients in that subnet.
Rotating the keys is recommended the keys so a potential hacker would not have enough data using a single

6.1.2.8.1 TKIP-CCMP Deployment Considerations
Before defining a TKIP-CCMP supported configuration on a WLAN, refer to the following deployment guidelines to
ensure the configuration is optimally effective:
• TKIP-CCMP should only be enabled for legacy device support when WPA2-CCMP support is not available.
• Though TKIP offers better security than WEP, it can be vulnerable to certain attacks.
Pre-Shared Key Enter either an alphanumeric string of 8 to 63 ASCII characters or 64
HEX characters as the primary string both transmitting and receiving
authenticators must share. The alphanumeric string allows character
spaces. The string is converted into a numeric value. This passphrase
saves the administrator from entering the 256-bit key each time keys are
generated.
Unicast Rotation
Interval
Define an interval for unicast key transmission in seconds (30 -86,400).
Some clients have issues using unicast key rotation, so ensure you know
which kind of clients are impacted before using unicast keys. This feature
is disabled by default.
Broadcast Rotation
Interval
When enabled, the key indices used for encrypting/decrypting broadcast
traffic are alternatively rotated based on the defined interval. Define an
interval for broadcast key transmission in seconds (30-86,400). Key
rotation enhances the broadcast traffic security on the WLAN. This
feature is disabled by default.
TKIP Countermeasure
Hold Time
The TKIP countermeasure hold-time is the time during which the use of
the WLAN is disabled if TKIP countermeasures have been invoked on the
WLAN. Use the drop-down menu to define a value in either Hours (0-18),
Minutes (0-1,093) or Seconds (0-65,535). The default setting is 1 second.
Exclude WPA2 TKIP Select this option for an Access Point to advertise and enable support
for only WPA-TKIP. This option can be used if certain older clients are
not compatible with the newer WPA2-TKIP information elements.
Enabling this option allows backwards compatibility for clients that
support WPA-TKIP and WPA2-TKIP but do not support WPA2-CCMP.
Enabling this feature is recommended if WPA-TKIP or WPA2-TKIP
supported clients operate in a WLAN populated by WPA2-CCMP
enabled clients. This feature is disabled by default.
Use SHA256 Select to enable use of the SHA-256 hash algorithms with WPA2. This is
optional when using WPA2 without 802.11w Protected Management
Frames (PMF) enabled. This is mandatory when PMF is enabled.
Wireless Configuration
Wireless Controller and Service Platform System Reference Guide 6 - 18
• When both TKIP and CCMP are both enabled a mix of clients are allowed to associate with the WLAN. Some
use TKIP, others use CCMP. Since broadcast traffic needs to be understood by all clients, the broadcast
encryption type in this scenario is TKIP.
6.1.2.9 WPA2-CCMP
Configuring WLAN Security
WPA2 is a newer 802.11i standard that provides even stronger wireless security than Wi-Fi Protected Access (WPA)
and WEP. CCMP is the security standard used by the Advanced Encryption Standard (AES). AES serves the same
function TKIP does for WPA-TKIP. CCMP computes a Message Integrity Check (MIC) using the proven Cipher Block
Chaining (CBC) technique. Changing just one bit in a message produces a totally different result.
WPA2/CCMP is based on the concept of a Robust Security Network (RSN), which defines a hierarchy of keys with
a limited lifetime (similar to TKIP). Like TKIP, the keys the administrator provides are used to derive other keys.
Messages are encrypted using a 128-bit secret key and a 128-bit block of data. The end result is an encryption
scheme as secure as any the wireless controller provides for its associated clients.
To configure WPA2-CCMP encryption on a WLAN:

WPA2-CCMP Deployment Considerations
WPA2-CCMP
Before defining a WPA2-CCMP supported configuration on a wireless controller WLAN, refer to the following
deployment guidelines to ensure the configuration is optimally effective:
• WPA2-CCMP should be configured for all new (non visitor) WLANs requiring encryption, as it’s supported by
the majority of the hardware and client vendors using wireless networking equipment.
• WPA2-CCMP supersedes WPA-TKIP and implements all the mandatory elements of the 802.11i standard. WPA2-
CCMP introduces a new AES-based algorithm called CCMP which replaces TKIP and WEP and is considered
significantly more secure.
6.1.2.10 WEP 64
Configuring WLAN Security
Wired Equivalent Privacy (WEP) is a security protocol specified in the IEEE Wireless Fidelity (Wi -Fi) standard.
WEP is designed to provide a WLAN with a level of security and privacy comparable to that of a wired LAN.
WEP can be used with open, shared, MAC and 802.1 X EAP authentications. WEP is optimal for WLANs supporting
legacy deployments when also used with 802.1X EAP authentication to provide user and device authentication and
dynamic WEP key derivation and periodic key rotation. 802.1X provides authentication for devices and also reduces
the risk of a single WEP key being deciphered. If 802.1X support is not available on the legacy device, MAC
authentication should be enabled to provide device level authentication.
WEP 64 uses a 40 bit key concatenated with a 24-bit initialization vector (IV) to form the RC4 traffic key. WEP 64
is a less robust encryption scheme than WEP 128 (containing a shorter WEP algorithm for a hacker to potentially
duplicate), but networks that require more security are at risk from a WEP flaw. WEP is only recommended if there

6.1.3 Configuring WLAN Firewall Support
Wireless LAN Policy
A firewall is a mechanism enforcing access control, and is considered a first line of defense in protecting
proprietary information within the network. The means by which this is accomplished varies, but in principle, a
firewall can be thought of as mechanisms both blocking and permitting data traffic. For an overview of firewalls,
see Wireless Firewall on page 10-1.
WLANs use firewalls like Access Control Lists (ACLs) to filter/mark packets based on the WLAN from which they
arrive, as opposed to filtering packets on Layer 2 ports. An ACL contains an ordered list of Access Control Entries
(ACEs). Each ACE specifies an action and a set of conditions (rules) a packet must satisfy to match the ACE. The
order of conditions in the list is critical since filtering is stopped after the first match.
IPv4 and IPv6 based firewall rules are specific to source and destination IP addresses and the unique rules and
precedence orders assigned. Both IP and non-IP traffic on the same Layer 2 interface can be filtered by applying
both an IP ACL and a MAC.
Additionally, administrators can filter Layer 2 traffic on a physical Layer 2 interface using MAC addresses. A MAC
firewall rule uses source and destination MAC addresses for matching operations, where the result is a typical
allow, deny or mark designation to WLAN packet traffic.
Keep in mind IP and non-IP traffic on the same Layer 2 interface can be filtered by applying both an IP ACL and a
MAC ACL to the interface.

its lower priority.
Action Every IP Firewall rule is made up of matching criteria rules. The action
defines the packet’s disposition if it matches the specified criteria. The
following actions are supported:
Deny - Instructs the Firewall to restrict a packet from proceeding to its
destination.
Allow - Instructs the Firewall to allow a packet to proceed to its destination.
DNS Name Specify the DNS Name which may be a full domain name, a portion of a
domain name or a suffix. This name is used for the DNS Match Type criteria.
DNS Match Type Specify the DNS matching criteria that the DNS Name can be matched
against. This can be configured as an exact match for a DNS domain name,
a suffix for the DNS name or a domain that contains a portion of the DNS
name. If traffic matches the configured criteria in the DNS Match Type, that
rule will be applied to the ACL.

4 Define the following Client Settings for the WLAN:
Enable
Client-to-Client
Communication
Select this option to enable client to client communication within this
WLAN. The default is enabled, meaning clients are allowed to
exchange packets with other clients. It does not necessarily prevent
clients on other WLANs from sending packets to this WLAN, but as
long as this setting also disabled on that WLAN, clients are not
permitted to interoperate.
Wireless Client Power Use this parameter to set the maximum transmit power (between 0 -
20 dBm) communicated to wireless clients for transmission within the
network. The default value is 20 dBm.
Wireless Client Idle Time Set the maximum amount of time wireless clients are allowed to be
idle within this WLAN. Set the idle time in either Seconds (60 -
86,400), Minutes (1 - 1,440), Hours (1 - 24) or Days (1). When this
setting is exceeded, the client is no longer able to access resources and
must re-authenticate. The default value is 1,800 seconds.
Max Firewall Sessions
per Client
Select this option to set the maximum amount of sessions (between 10
- 10,000) clients within the network over the Firewall. When enabled,
this parameter limits the number of simultaneous sessions allowed by
the Firewall per wireless client. This feature is disabled by default.
Max Clients Allowed Per
Radio
Use the spinner control to set the maximum number of clients (from 0
- 256) allowed to associate to each radio within this WLAN. The
default setting is 256.
Radio Resource
Measurement
Select this option to enable radio resource measurement capabilities
(IEEE 802.11k) on this WLAN. 802.11k improves how traffic is
distributed. In a WLAN, each device normally connects to an Access
Point with the strongest signal. Depending on the number and
locations of the clients, this arrangement can lead to excessive demand
on one Access Point and underutilization others, resulting in
degradation of overall network performance. With 802.11k, if the Access
Point with the strongest signal is loaded to its capacity, a client
connects to a underutilized Access Point. Even if the signal is weaker,
the overall throughput is greater since it’s an efficient use of the
network’s resources. This setting is disabled by default.
Radio Resource
Measurement Channel
Report
Select this option to enable radio resource measurement channel
reporting (IEEE 802.11k) on this WLAN. This setting is disabled by
default.
Enforce Client Load
Balancing
Select the check box to distribute clients evenly amongst associated
Access Point radios. This feature is disabled by default. Loads are
balanced by ignoring association and probe requests. Probe and
association requests are not responded to, forcing a client to associate
with another Access Point radio.
Enforce DHCP Client
Only
Select the check box to enforce that the firewall only allows packets
from clients if they used DHCP to obtain an IP address, disallowing
static IP addresses. This feature is disabled by default.
Proxy ARP Mode Use the drop-down menu to define the proxy ARP mode as either
Strict or Dynamic. Proxy ARP is the technique used to answer ARP
requests intended for another system. By faking its identity, the Access
Point accepts responsibility for routing packets to the actual
destination. Dynamic is the default value.

5 Define the following Wing Client Extensions to potentially increase client roaming reliability and handshake
speed:
6 Define the following Coverage Hole Detection settings to determine how detected coverage holes are managed:
Proxy ND Mode Use the drop-down menu to define the proxy neighbor discovery (ND)
mode for WLAN member clients as either Strict or Dynamic. ND Proxy
is used in IPv6 to provide reachability by allowing the a client to act as
proxy. Proxy certificate signing can be done either dynamically
(requiring exchanges of identity and authorization information) or
statically when the network topology is defined. Dynamic is the default
value.
Enforce DHCP-Offer
Validation
Select the check box to enforce DHCP offer validation. The default
setting is disabled.
Move Operations Select the check box to enable the use of Hyper-Fast Secure Roaming
(HFSR) for clients utilizing this WLAN. This feature applies only to
certain client devices. This feature is disabled by default.
Smart Scan Enable smart scan to adjust clients channel scans to a few channels as
opposed to all available channels. This feature is disabled by default.
Symbol Information
Element
Select the check box to support the Symbol Information Element with
legacy Symbol Technology clients, thus making them optimally
interoperable with the latest Extreme Networks Access Points. The
default setting is enabled.
WMM Load Information
Element
Select the check box to support a WMM Load Information Element in
radio transmissions with legacy clients. The default setting is disabled.
Scan Assist Enable scan assist to achieve faster roams on DFS channels by
eliminating passive scans. Clients would get channel information
directly from possible roam candidates. This setting is disabled by
default.
FT Aggregate Enable fast transition (FT) aggregate to increase roaming speed by
eliminating separate key exchange handshake frames with potential
roam candidates. Enable fast transition to complete an initial FT over
DS handshake with multiple roam candidates (up to 6) at once,
eliminating the need to send separate FT over DS handshakes to each
roam candidate. This setting is disabled by default.
Channel Info Interval Configure the channel information interval to periodically retrieve
channel information directly from potential roam candidates without
making a scan assist request.
Enable Enable this setting to inform an Access Point when it experiences a
coverage hole (area of poor wireless coverage). This setting is disabled
by default.
Use 11k Clients Optionally enable this setting to also use 802.11k-only-capable clients
to detect coverage holes. This is a reduced set of coverage hole
detection capabilities (only standard 11k messages and behaviors). This
setting is disabled by default.
Threshold Use the spinner control to set the Access Point signal strength (as seen
by the client) below which a coverage hole incident is reported. The
threshold can be set from -80 to -60.

WLAN to communicate with one another. This setting applies exclusively to CPE devices managed by a T5
controller and is disabled by default.
Use the Inactivity Time Out field to define the inactivity timeout specific to T5 clients. Set the maximum
amount of time T5 clients are allowed to be idle within this WLAN. Set the idle time in either Seconds (60 -
86,400), Minutes (1 - 1,440), Hours (0 - 24) or Days (0 - 1). When this setting is exceeded, the client is no
longer able to access resources and must reauthenticate. The default value is 1,800 seconds.
A T5 controller, once enabled as a supported external device, can provide data to WiNG to assist in a T5’s
management within a WiNG supported subnet populated by both types of devices. The Customer Premises
Equipment (CPEs) are the T5 controller managed radio devices. These CPEs use a Digital Subscriber Line (DSL)

Configuring Client Settings
Before defining a WLAN’s client settings, refer to the following deployment guidelines to ensure the configuration
is optimally effective:
• Clients on the same WLAN associated with an AAP can communicate locally at the AP Level without going
through the controller or service platform. If this is undesirable, an Access Point's
Client-to-Client Communication option should be disabled.
• When the wireless client idle time setting is exceeded, the client is no longer able to access WLAN resources
and must re-authenticate. The default value is 1,800 seconds.

6.1.5 Configuring WLAN Accounting Settings
Accounting is the method of collecting and sending security server information for billing, auditing, and reporting
user data; such as start and stop times, executed commands (such as PPP), number of packets and number of
bytes. Accounting enables wireless network administrators to track the services users are accessing and the
network resources they are consuming. When accounting is enabled, the network access server reports and logs
user activity to a RADIUS security server in the form of accounting records. Each accounting record is comprised
of AV pairs and is stored on a local access control server. The data can be analyzed for network management,
client billing, and/or auditing. Accounting methods must be defined through AAA.
Accounting can be enabled and applied to WLANs, to uniquely log accounting events specific to the WLAN.
Accounting logs contain information about the use of remote access services by users. This information is of great
assistance in partitioning local versus remote users and how to best accommodate each. Remote user information
can be archived to an external location for periodic network and user permission administration.
To configure WLAN accounting settings:
1Select
Configuration > Wireless LANs > Wireless LAN Policy to display available WLANs.

default.
6Select
OK when completed to update this WLAN’s accounting settings. Select Reset to revert the screen to its
last saved configuration.
6.1.5.1 Accounting Deployment Considerations
Before defining a WLAN AAA configuration, refer to the following deployment guidelines to ensure the
configuration is optimally effective:
• When using RADIUS authentication, the WAN port round trip delay should not exceed 150ms. Excessive delay
over a WAN can cause authentication and roaming issues. When excessive delays exists, a distributed RADIUS
service should be used.
• Authorization policies should be implemented when users need to be restricted to specific WLANs, or time and
date restrictions need to be applied.
• Authorization policies can also apply bandwidth restrictions and assign Firewall policies to users and devices.
6.1.6 Configuring WLAN Service Monitoring Settings
Wireless LAN Policy
Service Monitoring is a mechanism for administrating external AAA server, captive portal server, Access Point
adoption, and DHCP server activity for WLANs. Service monitoring enables an administrator to better notify users
of a service’s availability and make resource substitutions. Service monitoring can be enabled and applied to log
activity as needed for specific WLANs.
External services can be rendered unavailable due to any of the following instances:
• When the RADIUS authentication server becomes unavailable. The RADIUS server could be local or external
to the controller, service platform or Access Point.
Enable Syslog

6.2 Configuring WLAN QoS Policies
Wireless LAN Policy
QoS provides a data traffic prioritization scheme. QoS reduces congestion from excessive traffic. If there is enough
bandwidth for all users and applications (unlikely because excessive bandwidth comes at a very high cost), then
applying QoS has very little value. QoS provides policy enforcement for mission-critical applications and/or users
that have critical bandwidth requirements when bandwidth is shared by different users and applications.
QoS helps ensure each WLAN receives a fair share of the overall bandwidth, either equally or as per the proportion
configured. Packets directed towards clients are classified into categories such as Video, Voice and Data. Packets
within each category are processed based on the weights defined for each WLAN.
The Quality of Service screen displays a list of QoS policies available to WLANs. If none of the exiting QoS policies
supports an ideal QoS configuration for the intended data traffic of this WLAN, select the Add button to create
new policy. Select the radio button of an existing WLAN and select Ok to map the QoS policy to the WLAN
displayed in the banner of the screen.
Use the WLAN Quality of Service (QoS) Policy screen to add a new QoS policy or edit the attributes of an existing
policy.
Start Time This value sets the starting time the WLAN is activated. Use the
spinner controls to select the hour and minute, in a 12h time format.
Then use the radio button to choose AM or PM.
End Time This value sets the ending time of day(s) that the WLAN will be
disabled. Use the spinner controls to select the hour and minute, in a
12h time format. Then use the radio button to choose AM or PM.
NOTE: WLAN QoS configurations differ significantly from QoS policies configured
for radios. WLAN QoS configurations are designed to support the data requirements
of wireless clients, including the data types they support and their network
permissions. Radio QoS policies are specific to the transmit and receive
characteristics of the connected radio’s themselves, independent from the wireless
clients the Access Point radios supported.

WMM – Implies WiFi Multimedia QoS extensions are enabled on this
radio. This allows different traffic streams between the wireless client
and the Access Point to be prioritized according to the type of traffic
(voice, video etc). WMM classification is required to support the high
throughput data rates required of 802.11n device support.
Voice – Optimized for voice traffic. Implies all traffic on this WLAN is
prioritized as voice traffic on the radio.
Video – Optimized for video traffic. Implies all traffic on this WLAN is
prioritized as video traffic on the radio.
Normal – Optimized for best effort traffic. Implies all traffic on this
WLAN is prioritized as best effort traffic on the radio.
Low – Optimized for background traffic. Implies all traffic on this
WLAN is low priority on the radio.
Non-Unicast – Optimized for non-Unicast traffic. Implies all traffic on
this WLAN is designed for broadcast or multicast.

•Configuring Rate Limit Settings
6.2.1 Configuring a WLAN’s QoS WMM Settings
Using WMM, end-user satisfaction is maintained in a wider variety of environments and traffic conditions. WMM
makes it possible for both home networks and Enterprises to decide which data streams are most important and
assign them a higher traffic priority.
WMM’s prioritization capabilities are based on the four access categories. The higher the access category, the
higher the probability to transmit this kind of traffic over the WLAN. Access categories were designed to
correspond to 802.1d priorities to facilitate interoperability with QoS policy management mechanisms. WMM
enabled wireless controllers/Access Points coexist with legacy devices (not WMM-enabled).
Packets not assigned to a specific access category are categorized by default as having best effort priority.
Applications assign each data packet to a given access category packets are then added to one of four
independent transmit queues (one per access category - voice, video, best effort or background) in the client. The
SVP Prioritization A green check mark defines the policy as having Spectralink Voice
Prioritization (SVP) enabled to allow the wireless controller to identify
and prioritize traffic from Spectralink/Polycomm phones using the SVP
protocol. Phones using regular WMM and SIP are not impacted by SVP
prioritization. A red “X” defines the QoS policy as not supporting SVP
prioritization.
WMM Power Save Enables support for the WMM based power-save mechanism, also
known as Unscheduled Automatic Power Save Delivery (U-APSD). This
is primarily used by voice devices that are WMM capable. The default
setting is enabled.
Multicast Mask Primary Displays the primary multicast mask defined for each listed QoS policy.
Normally all multicast and broadcast packets are buffered until the
periodic DTIM interval (indicated in the 802.11 beacon frame), when
clients in power save mode wake to check for frames. However, for
certain applications and traffic types, the administrator may want the
frames transmitted immediately, without waiting for the DTIM interval.
By configuring a primary and secondary multicast mask, an
administrator can indicate which frames are transmitted immediately.
Setting masks is optional and only needed if there are traffic types
requiring special handling.
Multicast Mask
Secondary
Displays the secondary multicast mask defined for each listed QoS
policy.
NOTE: When using a wireless client classification other than WMM, only legacy rates
are supported on that WLAN.
Wireless Configuration
Wireless Controller and Service Platform System Reference Guide 6 - 54
client has an internal collision resolution mechanism to address collision among different queues, which selects the
frames with the highest priority to transmit.
The same mechanism deals with external collision, to determine which client(s) should be granted the opportunity
to transmit (TXOP). The collision resolution algorithm responsible for traffic prioritization is probabilistic and
depends on two timing parameters that vary for each access category.
• The minimum interframe space, or Arbitrary Inter-Frame Space Number (AIFSN)
• The contention window, sometimes referred to as the random backoff wait
Both values are smaller for high-priority traffic. The value of the contention window varies through time. Initially
the contention window is set to a value that depends on the AC. As frames with the highest AC tend to have the
lowest backoff values, they are more likely to get a TXOP.
After each collision the contention window is doubled until a maximum value (also dependent on the AC) is
reached. After successful transmission, the contention window is reset to its initial, AC dependant value. The AC
with the lowest backoff value gets the TXOP.

has infected on one or more devices. Rate limiting reduces the maximum rate sent or received from the wireless
network (and WLAN) per wireless client. It prevents any single user from overwhelming the wireless network. It
can also provide differential service for service providers. The uplink and downlink rate limits are usually configured
on a RADIUS server using vendor specific attributes. Rate limits are extracted from the RADIUS server’s response.
When such attributes are not present, the settings defined on the controller, service platform or Access Point are
applied. An administrator can set separate QoS rate limit configurations for data transmitted from the network
(upstream) and data transmitted from a WLAN’s wireless clients back to associated radios (downstream).
Before defining rate limit thresholds for WLAN upstream and downstream traffic, define the normal number of
ARP, broadcast, multicast and unknown unicast packets that typically transmit and receive from each supported
WMM access category. If thresholds are defined too low, normal network traffic (required by end-user devices) will
be dropped resulting in intermittent outages and performance problems.
Connected wireless clients can also have QoS rate limit settings defined in both the upstream and downstream
direction.

over a period of time, the average rate for each access category can
be obtained. Once a baseline is obtained, administrators should add a
10% margin (minimally) to allow for traffic bursts. The default burst
size is 320 kbytes.
Background Traffic Set a percentage value for background traffic in the upstream
direction. This is a percentage of the maximum burst size for low
priority traffic. Background traffic exceeding the defined threshold is
dropped and a log message is generated. Background traffic
consumes the least bandwidth of any access category, so this value
can be set to a lower value once a general upstream rate is known by
the network administrator (using a time trend analysis). The default
threshold is 50%.
Best Effort Traffic Set a percentage value for best effort traffic in the upstream direction.
This is a percentage of the maximum burst size for normal priority
traffic. Best effort traffic exceeding the defined threshold is dropped
and a log message is generated. Best effort traffic consumes little
bandwidth, so this value can be set to a lower value once a general
upstream rate is known by the network administrator (using a time
trend analysis). The default threshold is 50%.
Video Traffic Set a percentage value for video traffic in the upstream direction. This
is a percentage of the maximum burst size for video traffic. Video
traffic exceeding the defined threshold is dropped and a log message
is generated. Video traffic consumes significant bandwidth, so this
value can be set to a higher value once a general upstream rate is
known by the network administrator (using a time trend analysis). The
default threshold is 25%.
Voice Traffic Set a percentage value for voice traffic in the upstream direction. This
is a percentage of the maximum burst size for voice traffic. Voice
traffic exceeding the defined threshold is dropped and a log message

8 Configure the following parameters in respect to the intended Wireless Client Upstream Rate Limit:
Rate Define an upstream rate limit between 50 - 1,000,000 kbps. This limit
constitutes a threshold for the maximum the number of packets
transmitted or received over the WLAN (from all access categories).
Traffic that exceeds the defined rate is dropped and a log message is
generated. The default setting is 5000 kbps.
Maximum Burst Size Set a maximum burst size between 2 - 1024 kbytes. The smaller the
burst, the less likely the downstream packet transmission will result in
congestion for the WLAN’s client destinations. By trending the typical
number of ARP, broadcast, multicast and unknown unicast packets
over a period of time, the average rate for each access category can be
obtained. Once a baseline is obtained, administrators should add a 10%
margin (minimally) to allow for traffic bursts. The default burst size is
320 kbytes.
Background Traffic Set a percentage value for background traffic in the downstream
direction. This is a percentage of the maximum burst size for low
priority traffic. Background traffic exceeding the defined threshold is
dropped and a log message is generated. Background traffic
consumes the least bandwidth of any access category, so this value
can be set to a lower value once a general downstream rate is known
by the network administrator (using a time trend analysis). The default
threshold is 50%.
Best Effort Traffic Set a percentage value for best effort traffic in the downstream
direction. This is a percentage of the maximum burst size for normal
traffic. Best effort traffic exceeding the defined threshold is dropped
and a log message is generated. Best effort traffic consumes little
bandwidth, so this value can be set to a lower value once a general
downstream rate is known by the network administrator (using a time
trend analysis). The default threshold is 50%.
Video Traffic Set a percentage value for video traffic in the downstream direction.
This is a percentage of the maximum burst size for video traffic. Video
traffic exceeding the defined threshold is dropped and a log message

known by the network administrator (using a time trend analysis). The
default threshold is 25%.
Voice Traffic Set a percentage value for voice traffic in the downstream direction.
This is a percentage of the maximum burst size for voice traffic. Voice
traffic exceeding the defined threshold is dropped and a log message
is generated. Voice applications consume significant bandwidth, so this
value can be set to a higher value once a general upstream rate is

6.2.4 WLAN QoS Deployment Considerations
Before defining a QoS configuration on a WLAN, refer to the following deployment guidelines to ensure the
configuration is optimally effective:
• WLAN QoS configurations differ significantly from QoS policies configured for wireless controller associated
Access Point radios. WLAN QoS configurations are designed to support the data requirements of wireless
clients, including the data types they support and their network permissions. Radio QoS policies are specific to
the transmit and receive characteristics of the connected radio’s themselves, independent from the wireless
clients these Access Point radios support.
• Enabling WMM support on a WLAN only advertises WMM capability to wireless clients. The wireless clients
must be also able to support WMM and use the parameters correctly while accessing the wireless network to
truly benefit.
• Rate limiting is disabled by default on all WLANs. To enable rate limiting, a threshold must be defined for
WLAN.
• Before enabling rate limiting on a WLAN, a baseline for each traffic type should be performed. Once a baseline
has been determined, a minimum 10% margin should be added to allow for traffic bursts.
• The bandwidth required for real-time applications such as voice and video are very fairly easy to calculate as
the bandwidth requirements are consistent and can be realistically trended over time. Applications such as
Web, database and Email are harder to estimate, since bandwidth usage varies depending on how the
applications are utilized.
6.3 Radio QoS Policy
Without a dedicated QoS policy, a wireless network operates on a best-effort delivery basis, meaning all traffic has
equal priority and an equal chance of being delivered in a timely manner. When congestion occurs, all traffic has
an equal chance of being dropped!
When configuring a QoS policy for a radio, select specific network traffic, prioritize it, and use congestion-
management and congestion-avoidance techniques to provide deployment customizations best suited to each
QoS policy’s intended wireless client base.
Wireless devices, associated Access Point radios and connected clients support several Quality of Service (QoS)
techniques enabling real-time applications (such as voice and video) to co-exist simultaneously with lower priority
background applications (such as Web, E-mail and file transfers). A well designed QoS policy should:
Automatically Detect
Multicast Streams
Select this option to have multicast packets converted to unicast to
provide better overall airtime utilization and performance. The
administrator can either have the system automatically detect multicast
streams and convert all detected multicast streams to unicast, or
specify which multicast streams are converted to unicast. When the
stream is converted and queued for transmission, there are a number
of classification mechanisms that can be applied to the stream and the
administrator can select what type of classification they wan.
Manually Configure
Multicast Adddresses
Select this option and specify a list of multicast addresses and
classifications. Packets are accelerated when the destination addresses
matches.
Wireless Configuration
Wireless Controller and Service Platform System Reference Guide 6 - 67
• Classify and mark data traffic to accurately prioritize and segregate it (by access category) throughout the
network.
• Minimize the network delay and jitter for latency sensitive traffic.
• Ensure higher priority traffic has a better likelihood of delivery in the event of network congestion.
• Prevent the ineffective utilization of Access Points degrading session quality by configuring admission control
mechanisms within each radio QoS policy
Wireless clients supporting low and high priority traffic contend with one another for access and data resources.
The IEEE 802.11e amendment has defined Enhanced Distributed Channel Access (EDCA) mechanisms stating high
priority traffic can access the network sooner then lower priority traffic. The EDCA defines four traffic classes (or
access categories); voice (highest), video (next highest), best effort and background (lowest).The EDCA has
defined a time interval for each traffic class, known as the Transmit Opportunity (TXOP). The TXOP prevents traffic
of a higher priority from completely dominating the wireless medium, thus ensuring lower priority traffic is still
supported by controller or service platform associated Access Points and their connected radios.
IEEE 802.11e includes an advanced power saving technique called Unscheduled Automatic Power Save Delivery (U-
APSD) that provides a mechanism for wireless clients to retrieve packets buffered by an Access Point. U-APSD
reduces the amount of signaling frames sent from a client to retrieve buffered data from an Access Point. U-APSD
also allows Access Points to deliver buffered data frames as bursts, without backing-off between data frames.
These improvements are useful for voice clients, as they provide improved battery life and call quality.
The Wi-Fi alliance has created Wireless Multimedia (WMM) and WMM Power Save (WMM-PS) certification
programs to ensure interoperability between 802.11e WLAN infrastructure implementations and wireless clients. A
WiNG wireless network supports both WMM and WMM-Power Save techniques. WMM and WMM-PS (U-APSD) are
enabled by default in each WLAN profile.
Enabling WMM support on a WLAN just advertises the WLAN’s WMM capability and radio configuration to
wireless clients. The wireless clients must be also able to support WMM and use the values correctly while
accessing the WLAN.
WMM includes advanced parameters (CWMin, CWMax, AIFSN and TXOP) specifying back-off duration and inter-
frame spacing when accessing the network. These parameters are relevant to both connected Access Point radios
and their wireless clients. Parameters impacting Access Point transmissions to their clients are controlled using per
radio WMM settings, while parameters used by wireless clients are controlled by a WLAN’s WMM settings.
WiNG wireless devices include a Session Initiation Protocol (SIP), Skinny Call Control Protocol (SCCP) and
Application Layer Gateway (ALGs) enabling devices to identify voice streams and dynamically set voice call
bandwidth. Controllers and service platforms use the data to provide prioritization and admission control to these
devices without requiring TSPEC or WMM client support.
WiNG wireless devices support static QoS mechanisms per WLAN to provide prioritization of WLAN traffic when
legacy (non WMM) clients are deployed. When enabled on a WLAN, traffic forwarded to a client is prioritized and
forwarded based on the WLAN’s WMM access control setting.
NOTE: Statically setting a WLAN WMM access category value only prioritizes traffic
from the to the client, not from the client.

Rate limits can be applied to WLANs using groups defined locally or externally from a RADIUS server using Vendor
Specific Attributes (VSAs). Rate limits can be applied to authenticating users using 802.1X, captive portal

Firewall detection traffic
Enable (e.g., SIP)
A green check mark defines the policy as applying radio QoS settings
to traffic detected by the Firewall. A red “X” defines the policy as
having Firewall detection disabled. When enabled, the Firewall
simulates the reception of frames for voice traffic when the voice traffic
was originated via SIP or SCCP control traffic. If a client exceeds
configured values, the call is stopped and/or received voice frames are
forwarded at the next non admission controlled traffic class priority.
This applies to clients that do not send TSPEC frames only.

Implicit TSPEC A green check mark defines the policy as requiring wireless clients to
send their traffic specifications to a controller or service platform
managed Access Point before they can transmit or receive data. If
enabled, this setting applies to just this radio’s QoS policy. When
enabled, the Access Point simulates the reception of frames for any
traffic class by looking at the amount of traffic the client is receiving
and sending. If the client sends more traffic than has been configured
for an admission controlled traffic class, the traffic is forwarded at the
priority of the next non admission controlled traffic class. This applies
to clients that do not send TSPEC frames only.
Voice A green check mark indicates that Voice prioritization QoS is enabled
on the radio. A red X indicates Voice prioritization QoS is disabled on
the radio.
Best Effort A green check mark indicates that Best Effort QoS is enabled on the
radio. A red X indicates Best Effort QoS is disabled on the radio.
Video A green check mark indicates that Video prioritization QoS is enabled
on the radio. A red X indicates Video prioritization QoS is disabled on
the radio.
Background A green check mark indicates that Background prioritization QoS is
enabled on the radio. A red X indicates Background prioritization QoS
is disabled on the radio.

5 Set the following Normal (Best Effort) Access settings for the radio QoS policy:
6 Set the following Video Access settings for the Radio QoS policy:
Transmit Ops Use the slider to set the maximum duration a device can transmit after
obtaining a transmit opportunity. When resources are shared between
a Voice over IP (VoIP) call and a low priority file transfer, bandwidth is
normally exploited by the file transfer, thus reducing call quality or
even causing the call to disconnect. With voice QoS, a VoIP call (a real-
time session), receives priority, maintaining a high level of voice quality.
For higher-priority traffic categories (like voice), the Transmit Ops
value should be set to a low number. The default value is 47.
AIFSN Set the current AIFSN between 1-15. Higher-priority traffic voice
categories should have lower AIFSNs than lower-priority traffic
categories. This will cause lower-priority traffic to wait longer before
attempting access. The default value is 1.

6.3.2 Radio QoS Configuration and Deployment Considerations
Radio QoS Policy
• Before defining a radio QoS policy, refer to the following deployment guidelines to ensure the configuration is
optimally effective:
• To support QoS, each multimedia application, wireless client and WLAN is required to support WMM.
• WMM enabled clients can co-exist with non-WMM clients on the same WLAN. Non-WMM clients are always
assigned a Best Effort access category.
• Default WMM values should be used for all deployments. Changing these values can lead to unexpected traffic
blockages, and the blockages might be difficult to diagnose.
• Overloading an Access Point radio with too much high priority traffic (especially voice) degrades overall service
quality for all users.
• TSPEC admission control is only available with newer voice over WLAN phones. Many legacy voice devices do
not support TSPEC or even support WMM traffic prioritization.
Smart Aggregation Select to enable smart aggregation and dynamically define when an
aggregated frame is transmitted. Smart aggregation is disabled by
default.
Max Delay for Best
Effort
Set the maximum time (in milliseconds) to delay best effort traffic. The
default setting is 150 milliseconds.
Max Delay for
Background
Set the maximum time (in milliseconds) to delay background traffic.
The default setting is 250 milliseconds.
Max Delay for Streaming
Video
Set the maximum time (in milliseconds) to delay streaming video
traffic. The default setting is 150 milliseconds.
Max Delay for Video
Conferencing
Set the maximum time (in milliseconds) to delay video conferencing
traffic. The default setting is 40 milliseconds.
Max Delay for Voice Set the maximum time (in milliseconds) to delay voice traffic. The
default setting is 0 milliseconds.
Minimum frames per
Aggregate limit
Set the minimum number of frames to aggregate in a frame before it
is transmitted. The default setting is 8 frames.
Max Mesh Links Set the maximum number of mesh hops for smart aggregation. The
default setting is 3.

6.4 Association ACL
An association ACL is a policy-based ACL that either prevents or allows wireless clients from connecting to a
WLAN.
An association ACL affords a system administrator the ability to grant or restrict client access by specifying a
wireless client MAC address or range of MAC addresses to either include or exclude from connectivity.
Association ACLs are applied to WLANs as an additional access control mechanism. They can be applied to
WLANs from within a WLAN Policy’s Advanced configuration screen. For more information on applying an existing
Association ACL to a WLAN, see Configuring Advanced WLAN Settings.
To define an association ACL deployable with a WLAN:
1Select
Configuration > Wireless > Association ACL to display existing Association ACLs.
The Association Access Control List (ACL) screen lists those Association ACL policies created thus far. Any of
these policies can be selected and applied.
Figure 6-39 Association Access Control List (ACL) screen
2Select Add to define a new ACL configuration, Edit to modify an existing ACL configuration or Delete to remove
one. Optionally Copy or Rename a list as needed.

Association ACL If creating an new association ACL, provide a name specific to its
function. Avoid naming it after the WLAN it may support. The name
cannot exceed 32 characters.
Precedence The rules within a WLAN's ACL are applied to packets based on their
precedence values. Every rule has a unique sequential precedence
value you define. You cannot add two rules’s with the same
precedence. The default precedence is 1, so be careful to prioritize
ACLs accordingly as they are added.
Starting MAC Address Provide a starting MAC range address for clients requesting
association.
Ending MAC Address Provide an ending MAC range address for clients requesting
association.
Allow/Deny Use the drop-down menu to either Allow or Deny access if a MAC
address matches this rule.

Wireless Controller and Service Platform System Reference Guide 6 - 79
6.4.1 Association ACL Deployment Considerations
Association ACL
Before defining an Association ACL configuration and applying it to a WLAN, refer to the following deployment
guidelines to ensure the configuration is optimally effective:
• Use the Association ACL screen strategically to name and configure ACL policies meeting the requirements of
the particular WLANs they may map to. However, be careful not to name ACLs after specific WLANs, as
individual ACL policies can be used by more than one WLAN.
• You cannot apply more than one MAC based ACL to a Layer 2 interface. If a MAC ACL is already configured on
a Layer 2 interface, and a new MAC ACL is applied to the interface, the new ACL replaces the previously
configured one.
6.5 Smart RF Policy
Self Monitoring At Run Time RF Management (Smart RF) is a WiNG innovation designed to simplify RF
configurations for new deployments, while (over time) providing on-going deployment optimization radio
performance improvements.
A Smart RF policy can reduce deployment costs by scanning the RF environment to determine the best channel
and transmit power configuration for each radio. Smart RF policies can be applied to specific RF Domains, to apply
site specific deployment configurations and self-healing values to groups of devices within pre-defined physical RF
coverage areas.
Smart RF centralizes the decision process and makes intelligent RF configuration decisions using information
obtained from the RF environment. Smart RF helps reduce ongoing management and maintenance costs by
constantly monitoring the network for external interference, neighbor interference, non-WiFi interference and client
connectivity. Smart RF then intelligently applies various algorithms to arrive at the optimal channel and power
selection for all Access Points in the network and constantly reacts to changes in the RF environment.
Smart RF also provides self-healing functions by monitoring the network in real-time and provides automatic
mitigation from potentially problematic events such as radio interference, non-WiFi interference (noise), external
WiFi interference, coverage holes and radio failures. Smart RF employs self-healing to enable a WLAN to better
maintain wireless client performance and site coverage during dynamic RF environment changes, which typically
require manual reconfiguration to resolve.
Smart RF is supported on any RF Domain manager. In standalone environments, individual controllers, service
platforms or Access Points manage the calibration and monitoring phases. In clustered environments, a single
controller or service platform is elected a Smart RF master and the remaining cluster members operate as Smart
RF clients. In cluster operation, the Smart RF master co-ordinates the calibration and configuration and during the
monitoring phase receives information from the Smart RF clients.
If a Smart RF managed radio is operating in WLAN mode on a channel requiring DFS, it will switch channels if
radar is detected.
• If Smart RF is enabled, the radio picks a channel defined in the Smart RF policy.
• If Smart RF is disabled, but a Smart RF policy is mapped, the radio picks a channels specified in the Smart RF
policy
• If no SMART RF policy is mapped, the radio selects a random channel
Wireless Configuration
Wireless Controller and Service Platform System Reference Guide 6 - 80
If the radio is a dedicated sensor, it stops termination on that channel if a neighboring Access Points detects radar.
The Access Point attempts to come back to its original channel (statically configured or selected by Smart RF)
after the channel evacuation period has expired.
Change this behavior using a no dfs-rehome command from the controller or service platform CLI. This keeps the
radio on the newly selected channel and prevents the radio from coming back to the original channel, even after
the channel evacuation period.
To define a Smart RF policy:
1Select
Configuration > Wireless > Smart RF Policy to display existing Smart RF policies.
The Smart RF screen lists those Smart RF policies created thus far. Any of these policies can be selected and
applied.
The user has the option of displaying the configurations of each Smart RF Policy defined thus far, or referring to
the Smart RF Browser and either selecting individual Smart RF polices or selecting existing RF Domains to review
which Smart RF policies have been applied. For more information on how RF Domains function, and how to apply
a Smart RF policy, see About RF Domains and Managing RF Domains.

2 Refer to the following configuration data for existing Smart RF policies:
NOTE: RF planning must be performed to ensure overlapping coverage exists at a
deployment site for Smart RF to be a viable network performance tool. Smart RF
can only provide recovery when Access Points are deployed appropriately. Smart RF
is not a solution, it's a temporary measure. Administrators need to determine the
root cause of RF deterioration and fix it. Smart RF history/events can assist.

Interference Recovery Select the check box to enable Interference Recovery from neighboring
radios and other sources of WiFi and non-WiFi interference when
excess noise and interference is detected within the Smart RF
supported radio coverage area. Smart RF provides mitigation from
interference sources by monitoring the noise levels and other RF
parameters on an Access Point radio’s current channel. When a noise
threshold is exceeded, Smart RF can select an alternative channel with
less interference. To avoid channel flapping, a hold timer is defined
which disables interference avoidance for a specific period of time
upon detection. Interference Recovery is enabled by default.
Coverage Hole Recovery Select the check box to enable Coverage Hole Recovery when a radio
coverage hole is detected within the Smart RF supported radio
coverage area. When coverage hole is detected, Smart RF first
determines the power increase needed based on the signal to noise
ratio for a client as seen by the Access Point radio. If a client’s signal to
noise value is above the threshold, the transmit power is increased
until the signal to noise rate falls below the threshold.
Neighbor Recovery Select the check box to enable Neighbor Recovery when a failed radio
is detected within the Smart RF supported radio coverage area. Smart
RF can provide automatic recovery by instructing neighboring APs to
increase their transmit power to compensate for the coverage loss.
Neighbor recovery is enabled by default when the sensitivity setting is
medium.

5 GHz Channels Use the Select drop-down menu to define the 5 GHz channels used for
Smart RF assignments.
5 GHz Channel Width 20 and 40 MHz channel widths are supported by the 802.11a radio. 20/
40 MHz operation (the default setting for the 5 GHz radio) allows the
Access Point to receive packets from clients using 20 MHz of
bandwidth while transmitting a packet using 40 MHz bandwidth. This
mode is supported for 11n users on both the 2.4 and 5 GHz radios. If an
11n user selects two channels (a Primary and Secondary channel), the
system is configured for dynamic 20/40 operation. When 20/40 is
selected, clients can take advantage of wider channels. 802.11n clients
experience improved throughput using 40 MHz while legacy clients
(either 802.11a or 802.11b/g depending on the radio selected) can still
be serviced without interruption using 20 MHz. Select Automatic to
enable automatic assignment of channels to working radios to avoid
channel overlap and avoid interference from external RF sources.
40MHz is the default setting. If deploying an 802.11ac supported
Access Point, 80MHz channel width options are available as well.
2.4 GHz Channels Set the 2.4 GHz channels used in Smart RF scans.
2.4 GHz Channel Width 20 and 40 MHz channel widths are supported by the 802.11a radio. 20
MHz is the default setting for 2.4 GHz radios. 20/40 MHz operation
(the default setting for the 5 GHz radio) allows the Access Point to
receive packets from clients using 20 MHz of bandwidth while
transmitting a packet using 40 MHz bandwidth. This mode is
supported for 11n users on both the 2.4 and 5 GHz radios. If an 11n user

6.5.1 Smart RF Configuration and Deployment Considerations
Smart RF Policy
Before defining a Smart RF policy, refer to the following deployment guidelines to ensure the configuration is
optimally effective:
• The Smart RF calibration process impacts associated users and should not be run during business or
production hours. The calibration process should be performed during scheduled maintenance intervals or
non-business hours.
• For Smart RF to provide effective recovery, RF planning must be performed to ensure overlapping coverage
exists at the deployment site. Smart RF can only provide recovery when Access Points are deployed
appropriately. Smart RF is not a solution, it's a temporary measure. Administrators need to determine the
root cause of RF deterioration and fix it. Smart RF history/events can assist.
If a Smart RF managed radio is operating in WLAN mode on a channel requiring DFS, it will switch channels if
radar is detected.
• If Smart RF is enabled, the radio picks a channel defined in the Smart RF policy
• If Smart RF is disabled, but a Smart RF policy is mapped, the radio picks a channels specified in the Smart
RF policy
• If no SMART RF policy is mapped, the radio selects a random channel
If the radio is a dedicated sensor, it stops termination on that channel if a neighboring Access Points detects radar.
The Access Point attempts to come back to its original channel (statically configured or selected by Smart RF)
after the channel evacuation period has expired.
Change this behavior using a no dfs-rehome command from the controller or service platform CLI. This keeps the
radio on the newly selected channel and prevents the radio from coming back to the original channel, even after
the channel evacuation period.
Client Threshold Use the spinner to set a client threshold for the Smart RF policy
between 1 - 255. This is the minimum number of clients a radio should
have associated in order for coverage hole recovery to trigger. The
default setting is 1.
SNR Threshold Use the spinner control to set a signal to noise threshold (between 1 -
75 dB). This is the signal to noise threshold for an associated client as
seen by its associated Access Point radio. When exceeded, the radio
increases its transmit power in order to increase coverage for the
associated client. The default value is 20 dB.
Coverage Interval Define the interval coverage hole recovery should be initiated after a
coverage hole is detected. The default is 10 seconds for both the 2.4
and 5.0 GHz radios.
Interval Define the interval coverage hole recovery should be conducted before
a coverage hole is detected. The default is 30 seconds for both the 2.4
and 5.0 GHz radios.

Wireless Controller and Service Platform System Reference Guide 6 - 91
6.6 MeshConnex Policy
MeshConnex is a mesh networking technology that is comparable to the 802.11s mesh networking specification.
MeshConnex meshing uses a hybrid proactive/on-demand path selection protocol, similar to Ad hoc On Demand
Distance Vector (AODV) routing protocols. This allows it to form efficient paths using multiple attachment points
to a distribution WAN, or form purely ad-hoc peer-to-peer mesh networks in the absence of a WAN. Each device
in the MeshConnex mesh proactively manages its own path to the distribution WAN, but can also form peer-to-
peer paths on demand to improve forwarding efficiency. MeshConnex is not compatible with MiNT Based meshing,
though the two technologies can be enabled simultaneously in certain circumstances.
MeshConnex is designed for large-scale, high-mobility outdoor mesh deployments. MeshConnex continually
gathers data from beacons and transmission attempts to estimate the efficiency and throughput of each MP-to-MP
link. MeshConnex uses this data to dynamically form and continually maintain paths for forwarding network

In MeshConnex systems, a mesh point (MP) is a virtual mesh networking instance on a device, similar to a WLAN
AP. On each device, up to 4 MPs can be created and 2 can be created per radio. MPs can be configured to use one
or both radios in the device. If the MP is configured to use both radios, the path selection protocols will continually
select the best radio to reach each destination. Each MP participates in a single Mesh Network, defined by the
MeshID. The MeshID is typically a descriptive network name, similar to the SSID of a WLAN. All MPs configured to
use the same MeshID attempt to form a mesh and interoperate. The MeshID allows overlapping mesh networks to
discriminate and disregard MPs belonging to different networks.

6.7 Mesh QoS Policy
Mesh Quality of Service (QoS) provides a data traffic prioritization scheme. QoS reduces congestion from excessive
traffic. If there is enough bandwidth for all users and applications (unlikely because excessive bandwidth comes at
a very high cost), then applying QoS has very little value. QoS provides policy enforcement for mission-critical
applications and/or users that have critical bandwidth requirements when bandwidth is shared by different users
and applications.
Mesh QoS helps ensure each mesh point on the mesh network receives a fair share of the overall bandwidth, either
equally or as per the proportion configured. Packets directed towards clients are classified into categories such as
video, voice and data. packets within each category are processed based on the weights defined for each mesh
point.
The Quality of Service screen displays a list of Mesh QoS policies available to mesh points. Each mesh QoS policy
can be selected to edit its properties. If none of the exiting Mesh QoS policies supports an ideal QoS configuration
for the intended data traffic of this mesh point, select the Add button to create new policy. Select an existing mesh
QoS policy and select Edit to change the properties of the Mesh QoS policy.
To define a Mesh QoS policy:
1Select
Configuration > Wireless > Mesh QoS Policy to display existing Mesh QoS policies.
Figure 6-54 Mesh QoS Policy screen
Wireless Configuration
Wireless Controller and Service Platform System Reference Guide 6 - 98
2 Refer to the following configuration data for existing Smart RF policies:

to modify its existing configuration. Existing QoS policies can be selected and deleted as needed. Optionally
Copy or Rename a policy as needed.
The Rate Limit screen displays by default for the new or modified QoS policy.
Excessive traffic can cause performance issues or bring down the network entirely. Excessive traffic can be
caused by numerous sources including network loops, faulty devices or malicious software such as a worm or
virus that has infected on one or more devices at the branch. Rate limiting limits the maximum rate sent to or
received from the wireless network (and mesh point) per neighbor. It prevents any single user from
overwhelming the wireless network. It can also provide differential service for service providers. An
administrator can set separate QoS rate limit configurations for data transmitted from the network and data
transmitted from a mesh point’s neighbor back to their associated Access Point radios and managing controller
or service platform.
Before defining rate limit thresholds for mesh point transmit and receive traffic, define the normal number of
ARP, broadcast, multicast and unknown unicast packets that typically transmit and receive from each
supported WMM access category. If thresholds are defined too low, normal network traffic (required by end-
user devices) is dropped, resulting in intermittent outages and performance problems.
A connected neighbor can also have QoS rate limit settings defined in both the transmit and receive direction.
Mesh QoS Policy Displays the administrator assigned name of each mesh QoS policy.
Mesh Tx Rate Limit Displays whether or not a Mesh Tx Rate Limit is enabled for each Mesh
QoS policy. When the rate limit is enabled a green check mark is

controller to associated Access Point radios and their associated neighbor:
Mesh Tx Rate Limit Select the check box to enable rate limiting for all data received from
any mesh point in the mesh network. This feature is disabled by
default.
Rate Define a receive rate limit between 50 - 1,000,000 kbps. This limit
constitutes a threshold for the maximum the number of packets
transmitted or received over the mesh point (from all access
categories). Traffic that exceeds the defined rate is dropped and a log
message is generated. The default setting is 5000 kbps.
Maximum Burst Size Set a maximum burst size between 2 - 1024 kbytes. The smaller the
burst, the less likely the transmit packet transmission will result in
congestion for the mesh point’s client destinations. By trending the
typical number of ARP, broadcast, multicast and unknown unicast
packets over a period of time, the average rate for each access
category can be obtained. Once a baseline is obtained, administrators
should then add a 10% margin (minimally) to allow for traffic bursts at
the site. The default burst size is 320 kbytes.

neighbors to associated Access Point radios and the controller or service platform:
Background Traffic Set a percentage value for background traffic in the transmit direction.
This is a percentage of the maximum burst size for low priority traffic.
Background traffic exceeding the defined threshold is dropped and a
log message is generated. Background traffic consumes the least
bandwidth of any access category, so this value can be set to a lower
value once a general transmit rate is known by the network
administrator (using a time trend analysis). The default threshold is
50%.
Best Effort Traffic Set a percentage value for best effort traffic in the transmit direction.
This is a percentage of the maximum burst size for normal priority
traffic. Best effort traffic exceeding the defined threshold is dropped
and a log message is generated. Best effort traffic consumes little
bandwidth, so this value can be set to a lower value once a general
transmit rate is known by the network administrator (using a time
trend analysis). The default threshold is 50%.
Video Traffic Set a percentage value for video traffic in the transmit direction. This is
a percentage of the maximum burst size for video traffic. Video traffic
exceeding the defined threshold is dropped and a log message is
generated. Video traffic consumes significant bandwidth, so this value
can be set to a higher value once a general transmit rate is known by
the network administrator (using a time trend analysis). The default
threshold is 25%.
Voice Traffic Set a percentage value for voice traffic in the transmit direction. This is
a percentage of the maximum burst size for voice traffic. Voice traffic
exceeding the defined threshold is dropped and a log message is
generated. Voice applications consume significant bandwidth, so this
value can be set to a higher value once a general upstream rate is
known by the network administrator (using a time trend analysis). The
default threshold is 0%.
Mesh Rx Rate Limit Select the check box to enable rate limiting for all data transmitted by
the device to any mesh point in the mesh. This feature is disabled by
default.
Rate Define an transmit rate limit between 50 - 1,000,000 kbps. This limit

Background Traffic Set a percentage value for background traffic in the receive direction.
This is a percentage of the maximum burst size for low priority traffic.
Background traffic exceeding the defined threshold is dropped and a
log message is generated. Background traffic consumes the least
bandwidth of any access category, so this value can be set to a lower
value once a general receive rate is known by the network
administrator (using a time trend analysis). The default threshold is
50%.
Best Effort Traffic Set a percentage value for best effort traffic in the receive direction.
This is a percentage of the maximum burst size for normal traffic. Best
effort traffic exceeding the defined threshold is dropped and a log
message is generated. Best effort traffic consumes little bandwidth, so
this value can be set to a lower value once a general receive rate is
known by the network administrator (using a time trend analysis). The
default threshold is 50%.
Video Traffic Set a percentage value for video traffic in the receive direction. This is
a percentage of the maximum burst size for video traffic. Video traffic
exceeding the defined threshold is dropped and a log message is
generated. Video traffic consumes significant bandwidth, so this value
can be set to a higher value once a general receive rate is known by
the network administrator (using a time trend analysis). The default
threshold is 25%.
Voice Traffic Set a percentage value for voice traffic in the receive direction. This is
a percentage of the maximum burst size for voice traffic. Voice traffic
exceeding the defined threshold is dropped and a log message is
generated. Voice applications consume significant bandwidth, so this
value can be set to a higher value once a general transmit rate is
known by the network administrator (using a time trend analysis). The
default threshold is 0%. 0% means no early random drops will occur.
Neighbor Rx Rate Limit Select the radio button to enable rate limiting for data transmitted
from the client to its associated Access Point radio and connected
controller or service platform. Enabling this option does not invoke
client rate limiting for data traffic in the receive direction. This feature

WiNG managed clients can use Online Sign-Up (OSU) for registration and credential provisioning to obtain
hotspot network access. Service providers have an OSU AAA server and certificate authority (CA). For a client
and hotspot to trust one another, the OSU server holds a certificate signed by a CA whose root certificate is
issued by a CA authorized by the Wi-Fi Alliance, and CA certificates are installed on the client device. A CA
performs four functions:
• Issues certificates (creates and signs)
• Maintains certificate status information and issues certificate revocation lists (CRLs)
• Publishes current (non-expired) certificates and CRLs
• Maintains status archives for the expired or revoked certificates it has issued
Passpoint certificates are governed by the Hotspot 2.0 OSU Certificate Policy Specification. An OSU server
certificate should be obtained from any of the CAs authorized by the Wi-Fi Alliance. Once an OSU provider is
selected, the client connects to the OSU WLAN. It then triggers an HTTPS connection to the OSU server, which
was received with the OSU providers list. The client validates the server certificate to ensure it's a trusted OSU
server. The client is prompted to complete an online registration through their browser. When the client has a
valid credential for the hotspot 2.0 WLAN, it disassociates from the OSU WLAN and connects to the hotspot
2.0 WLAN.
The OSU Provider screen displays those provider configurations created thus far for utilization with a passpoint

In addition to WIPS support, sensor functionality has now been added for Extreme Networks’ MPact locationing
system. The MPact system for Wi-Fi locationing includes WiNG controllers and Access Points functioning as
sensors. Within the MPact architecture, sensors scan for RSSI data on an administrator defined interval and send to
a dedicated MPact Server resource, as opposed to an ADSP server. The MPact Server collects the RSSI data from
WiNG sensor devices, and calculates the location of Wi-Fi devices for MPact administrators.

Network Configuration
Controllers, service platforms and Access Points allow packet routing customizations and unique network
resources for deployment specific routing configurations.
For more information on the options available, refer to the following:

•Network Deployment Considerations
7.1 Policy Based Routing
Define a policy based routing (PBR) configuration to direct packets to selective paths. PBR can optionally mark
traffic for preferential services. PBR minimally provides the following:
• A means to use source address, protocol, application and traffic class as traffic routing criteria
• The ability to load balance multiple WAN uplinks
• A means to selectively mark traffic for QoS optimization
Since PBR is applied to incoming routed packets, a route-map is created containing a set of filters and associated
actions. Based on the actions defined in the route-map, packets are forwarded to the next relevant hop. Route-
maps are configurable under a global policy called routing-policy, and applied to profiles and devices.
Route-maps contain a set of filters which select traffic (match clauses) and associated actions (set clauses) for
routing. A routemap consists of multiple entries, each carrying a precedence value. An incoming packet is matched
against the route-map with the highest precedence (lowest numerical value). If it matches, the routing decision is
based on this route-map. If the packet does not match the route-map, the route-map entry with next highest
precedence is matched. If the incoming packet does not match any of the route-map entries, it’s subjected to
typical destination based routing. Each route-map entry can optionally enable/disable logging.
The following criteria can optionally be used as traffic selection segregation criteria:
•IP Access List - A typical IP ACL can be used for traffic permissions. The mark and log actions in ACL rules
however are neglected. Route-map entries have separate logging. Only one ACL can be configured per route
map entry.
Network Configuration
Wireless Controller and Service Platform System Reference Guide 7 - 2
•IP DSCP - Packet filtering can be performed by traffic class, as determined from the IP DSCP field. One DSCP
value is configurable per route map entry. If IP ACLs on a WLAN, ports or SVI mark the packet, the new/
marked DSCP value is used for matching.
•Incoming WLAN - Packets can be filtered by the incoming WLAN. There are two ways to match the WLAN:
- If the device doing policy based routing has an onboard radio and a packet is received on a local WLAN, then
this WLAN is used for selection.
- If the device doing policy based routing does not have an onboard radio and a packet is received from an
extended VLAN, then the device which received the packet passes the WLAN information in the MINT packet
for the PBR router to use as match criteria.
•Client role - The client role can be used as match criteria, similar to a WLAN. Each device has to agree on a
unique identifier for role definition and pass the same MINT tunneled packets.
•Incoming SVI - A source IP address qualifier in an ACL typically satisfies filter requirements. But if the host
originating the packet is multiple hops away, the incoming SVI can be used as match criteria. In this context
the SVI refers to the device interface performing policy based routing, and not the originating connected
device.
Each route map entry has a set of match and set (action) clauses. ACL rules configured under route map entries
merge to create a single ACL. Route map precedence values determine the prioritization of the rules in this
merged ACL. An IP DSCP value is also added to the ACL rules.
Set (or action) clauses determine the routing function when a packet satisfies match criteria. If no set clauses are
defined, the default is to fallback to destination based routing for packets satisfying the match criteria. If no set
clause is configured and fallback to destination based routing is disabled, then the packet is dropped. The
following can be defined within set clauses:
•Next hop - The IP address of the next hop or the outgoing interface through which the packet should be
routed. Up to two next hops can be specified. The outgoing interface should be a PPP, a tunnel interface or a
SVI which has DHCP client configured. The first reachable hop should be used, but if all the next hops aren’t
reachable, typical destination based route lookup is performed.
•Default next hop - If a packet subjected to PBR does not have an explicit route to the destination, the
configured default next hop is used. This can be either the IP address of the next hop or the outgoing interface.
Only one default next hop can be defined. The difference between the next hop and the default next-hop is in
case of former, PBR occurs first, then destination based routing. In case of the latter, the order is reversed. With
both cases:
a If a defined next hop is reachable, it’s used. If fallback is configured refer to (b).
b Do normal destination based route lookup. If a next hop is found its used, if not refer to (c).
c If default next hop is configured and reachable, it’s used. If not, drop the packet.
•Fallback - Fallback to destination based routing if none of the configured next hops are reachable (or not
configured). This is enabled by default.
•Mark IP DSCP - Set IP DSCP bits for QoS using an ACL. The mark action of the route maps takes precedence
over the mark action of an ACL.
To define a PBR configuration:
1 Select the Configuration tab from the Web UI.
2Select
Network.
NOTE: A packet should optimally satisfy all the match criteria, if no match clause is
defined in a route-map, it would match everything. Packets not conforming to any
of the match clauses are subjected to normal destination based routing.
