Obtaining the vSCG Distribution
From the vSCG download page on the Ruckus Wireless support website, download
the .OVA file and documentation for the vSCG appliance. The vSCG distribution
package, which is based on the Open Virtualization Format (OVF) framework,
consists of a virtual appliance containing the following files:
• Description file (.ovf)
• Manifest file (.mf)
• Virtual machine state file (.vmdk)
These three files are consolidated into a TAR archive file and distributed as an Open
Virtual Appliance (OVA) package. This OVA package can be imported directly into
your chosen hypervisor.

Preparing to Install the vSCG
Preparing the vSCG Interface Settings to Use

Preparing the vSCG Interface Settings to Use
The vSCG comes with the option to operate with either one (1) network interface
or three (3) network interfaces (see Table 4). Once the network interface configuration has been made and setup executed, the number of network interfaces can no
longer be modified.
CAUTION! If you choose to operate the vSCG with three network interfaces, you
must configure the three vSCG interfaces to be on three different subnets when you
run the Setup Wizard. Failure to do so may result in loss of access to the web
interface or failure of system functions and services.
Before installing the vSCG, prepare the following required network settings:
• IP address
• Netmask
• Gateway
• Primary DNS server
• Secondary DNS server

Preparing to Install the vSCG
Determining the System Resources That the Virtual Machine Requires

Determining the System Resources That the
Virtual Machine Requires
The number of APs and clients that the vSCG can support depends on the system
resources (CPU and memory) that the virtual machine running the vSCG has. The
vSCG is capable of automatically scaling to and supporting a higher number of APs
and clients if it determines, at system bootup, that there is sufficient CPU and
memory on the virtual machine to support more APs and clients.
Table 5 (carrier profile configuration) and Table 6 (enterprise profile configuration) list
the maximum recommended number of APs and clients that the vSCG can support
based on the available vCPU and memory available on the virtual machine1. The
first row in Table 5, for example, shows that to support 25 APs, the vSCG must have
at least 2-core CPU and 7GB of RAM. Whenever the CPU or memory settings are
changed, the vSCG instance must be rebooted for the updated settings to be
applied to it.

Installing the vSCG on VMWare™ vSphere Hypervisor

Setting Up the vSCG Interface or Interfaces
The vSCG comes with the option to operate with either one (1) network interface
or three (3) network interfaces. Therefore the procedure for setting up the vSCG
interface depends on the number of interfaces that it has.
Follow the procedure below that corresponds to the number of interfaces that the
vSCG you are installing has.
• Setting Up a vSCG with One Interface
• Setting Up a vSCG with Three Interfaces
NOTE: By default, the VMWare Esxi package comes with three network interfaces.
If you want to deploy the vSCG with only one interface, you can edit the virtual
machine settings to remove the extra interfaces. The KVM package, on the other
hand, comes with a single interface. If you want to deploy the vSCG with three
interfaces, edit the virtual machine settings to create two additional interfaces.

Setting Up a vSCG with One Interface
Follow these steps to set up the vSCG with a single network interface.
1 Log on to the console using the following credentials:
• User name: admin
• Password: admin
2 At the SCG> prompt, enter en to enable privileged mode.
3 At the Password prompt, enter admin. The SCG# prompt appears.

Installing the vSCG on a Kernel-based Virtual Machine Hypervisor

Important Notes About Selecting the System Default Gateway
Depending on your network topology, you may select either the Management or
Control interface as the system default gateway.
• If all of the managed APs are located in different locations on the Internet, the
vSCG may not know all of the IP subnets of these APs. In this case, the control
interface should be set as the default gateway for the vSCG and you will need
to add a static route to reach the management network.
• If all of the managed APs belong to a single subnet or to multiple subnets on
which you can set the route statically, then you can set the management interface
as the default gateway users can set default gateway for the vSCG and set static
routes for the vSCG to reach all of its managed APs.

Installing the vSCG on a Kernel-based Virtual
Machine Hypervisor
This section describes how to install the vSCG on a KVM hypervisor.
• Extracting the vSCG Image

Configuring the vSCG Carrier for the First Time
Creating an AP Zone

Creating an AP Zone
The first step in configuring the vSCG is to create an AP zone. An AP zone functions
as a way of grouping APs and applying a particular set of settings (including WLANs
and their settings) to these groups of APs. Each AP zone can include up to six WLAN
services.
A zone called Staging Zone exists by default. Any AP that registers with the vSCG
that is not assigned a specific zone is automatically assigned to the Staging Zone.
Follow these steps to create a new AP zone.
1 Click Configuration > AP Zones.
2 Click Create New.

Description

Client Load Balancing

Improve WLAN performance by enabling load
balancing. Load balancing spreads the wireless client
load between nearby access points, so that one AP
does not get overloaded while another sites idle. Load
balancing must be enabled on a per-radio basis. To
enable load balancing, select the Enable load
balancing on [2.4GHz or 5GHz] check box, and then
set or accept the default Adjacent Radio Threshold
(50dB for the 2.4GHz radio and 43dB for the 5GHz
radio).

Smart Monitor

To disable the WLANs of an AP (that belongs to this
zone) whenever the AP uplink or Internet connection
becomes unavailable, select the Enable check box. And
then, configure the following options:
• Health Check Interval: Set the interval (between 5 and
60 seconds) at which the vSCG will check the AP’s
uplink connection. The default value is 10 seconds.
• Health Check Retry Threshold: Set the number of
times (between 1 and 10 times) that the vSCG will
check the AP’s uplink connection. If the vSCG is
unable to detect the uplink after the configured
number of retries, the vSCG will disable the AP’s
WLANs. The default value is 3 retries.
NOTE: When the vSCG disables the AP’s WLANs, the
AP creates a log for the event. When the AP’s uplink is
restored, the AP sends the event log (which contains the
timestamp when the WLANs were disabled, and then
enabled) to the vSCG.

4 Click Create New to finish creating your first AP Zone. When the vSCG
completes creating the AP zone, the following confirmation message appears:

Configuring the vSCG Carrier for the First Time
Configuring AAA Servers and Hotspot Settings

You have completed creating your first AP zone. You can create additional AP zones,
if needed.

Configuring AAA Servers and Hotspot
Settings
NOTE: If you do not have an AAA server on the network, skip this step.
If you have an existing RADIUS (AAA) server on the network, you can set up hotspot
services across the network using the Ruckus Wireless access points that the vSCG
is managing. To provide hotspot services, you need to add at least one AAA server
to the vSCG and create a hotspot service.
AAA servers and hotspot settings must be configured on a per-AP zone basis.

Adding an AAA Server
Follow these steps to add an AAA server to an AP zone.
1 Go to Configuration > AP Zones.
2 Click the AP zone for which you want to add an AAA server. Alternatively, click
the AP zone from the Management Domains tree.
3 Under the AP Zones menu on the sidebar, click AAA.
4 Click Create New. The Create New RADIUS Server form appears.
5 In the General Options section, configure the following settings:
• Name: Type a name for the AAA server that you are adding.
• Description: Type a description for the AAA server that you are adding.
• Type: Click either RADIUS or RADIUS Accounting, depending on the type
of RADIUS server that you are using.
• Backup RADIUS: If a backup RADIUS server exists on the network, you may
enable RADIUS backup support by selecting the Enable backup RADIUS
support check box.
6 Configure the options in the Health Check Policy section. These options define
the health monitoring settings of the primary RADIUS server by the secondary
RADIUS server. The secondary RADIUS is responsible for monitoring the health
of the primary RADIUS and for periodically synchronizing its settings to match
those of the primary RADIUS.

• Response Window: Set the time (in seconds) during which the secondary
RADIUS must wait for a response from the primary RADIUS. If the secondary
RADIUS does not receive a response during the defined Response Window,
the Zombie Period (see below) is started for the primary RADIUS. The default
Response Window is 20 seconds.
• Zombie Period: Set the time (in seconds) during which the secondary RADIUS
must wait for a response from the primary RADIUS before marking it as
“down”. If the secondary RADIUS does not receive a response during the
defined Zombie Period, the Revive Interval (see below) is started for the
primary server. The default Zombie Period is 40 seconds. If the primary
RADIUS still does not respond when the Zombie Period expires, it will be
marked as down and the secondary RADIUS will start receiving new requests
from the Network Access Server (NAS).
• Revive Interval: Set the time (in seconds) during which the secondary RADIUS
must wait for the primary RADIUS to start responding to requests again. If
the primary RADIUS starts responding before the Revive Interval expires, new
requests will be forwarded to the primary RADIUS again. The default Revive
Interval is 120 seconds.
• No Response Fail: Click Yes to respond with a reject message to the NAS if
no response is received from the RADIUS server. Click No to skip sending a
response.

the WLAN name is the same as the advertised SSID (the name of the wireless
network as displayed in the client’s wireless configuration program). However,
you can also separate the ESSID from the WLAN name by entering a name for
the WLAN in the first field, and a broadcast SSID in the second field. In this way,
you can advertise the same SSID in multiple locations (controlled by the same

• Description: Enter a brief description of the qualifications or purpose of this
WLAN (for example, Engineering or Voice).

WLAN Usage
• In Access Network, select the Tunnel WLAN traffic to vSCG check box if you
want to tunnel the traffic from this WLAN back to the vSCG. Tunnel mode enables
wireless clients to roam across different APs on different subnets. If the WLAN

devices), Ruckus Wireless recommends enabling tunnel mode. When you
enable this option, you need to select core network for tunneling WLAN traffic
back to the vSCG.
• In Authentication Type, click one of the following options:
• Standard usage (For most regular wireless networks): This is a regular
WLAN suitable for most wireless networks.
• Hotspot service (WISPr): Click this option if want to use a hotspot (WISPr)
service that you previously created.
• Hotspot 2.0: Click this option if you want to use a Hotspot 2.0 profile that
you previously created.
• Guest Access: Click this option if you want to use this WLAN for guest
access.

Authentication Options
Authentication defines the method by which users are authenticated prior to gaining
access to the WLAN. The level of security should be determined by the purpose of
the WLAN you are creating.
• Open [Default]: No authentication mechanism is applied to connections. If WPA
or WPA2 encryption is used, this implies WPA-PSK authentication.
• 802.1X/EAP: Uses 802.1X authentication against a user database.
• MAC Address: Uses the MAC address of a client for authentication. MAC
address authentication requires a RADIUS server and uses the MAC address as
the user logon name and password. You have two options for the MAC address
format to use for authenticating clients:
• Use user defined text as authentication password (default is device MAC
address)
• Set device MAC address in 802.1x format 00-10-A4-23-19-C0. The default
is 0010a42319c0.

Encryption Options
Encryption choices include WPA, WPA2, WPA-Mixed, WEP and none. WPA and
WPA2 are both encryption methods certified by the Wi-Fi Alliance and are the
recommended encryption methods. The Wi-Fi Alliance will be mandating the
removal of WEP due to its security vulnerabilities, and Ruckus Wireless recommends
against using WEP if possible.

Virtualized SmartCell Gateway Getting Started Guide for RuckOS 3.0.3, 800-70797-001 Rev A

75

Configuring the vSCG Carrier for the First Time
Defining the WLAN Settings of an AP Zone

Method
• WPA: Standard Wi-Fi Protected Access with either TKIP or AES encryption.
• WPA2: Enhanced WPA encryption using the stronger AES encryption algorithm.
• WPA-Mixed: Allows mixed networks of WPA and WPA2 compliant devices. Use
this setting if your network has a mixture of older clients that only support WPA
and TKIP, and newer client devices that support WPA2 and AES.
• WEP-64: Provides a lower level of encryption, and is less secure, using 40-bit
WEP encryption.
• WEP-128: Provides a higher level of encryption than WEP-64, using a 104-bit
key for WEP encryption. However, WEP is inherently less secure than WPA.
• None: No encryption; communications are sent in clear text.
CAUTION! If you set the encryption method to WEP-64 (40 bit) or WEP-128 (104
bit) and you are using an 802.11n AP for the WLAN, the AP will operate in 802.11g
mode.

Algorithm (For WPA or WPA2 Encryption Only)
• TKIP: This algorithm provides greater compatibility with older client devices, but
retains many of the security weaknesses of WEP. Therefore, if you select TKIP
encryption, 11n devices will be limited to 11g transfer rates. Furthermore, the
Wi-Fi Alliance will be mandating the removal of TKIP, so it should not be used.
• AES: This algorithm provides enhanced security over TKIP, and is the only
encryption algorithm supported by the 802.11i standard. Choose AES encryption if you are confident that all of your clients will be using 802.11i-compliant
NICs.
• Auto: Automatically selects TKIP or AES encryption based on the client’s
capabilities. Note that since it is possible to have clients using both TKIP and
AES on the same WLAN, only unicast traffic is affected (broadcast traffic must
fall back to TKIP; therefore, transmit rates of broadcast packets from 11n APs
will be at lower 11g rates).
CAUTION! If you set the encryption algorithm to TKIP and you are using an 802.11n
AP for the WLAN, the AP will operate in 802.11g mode.

76

Configuring the vSCG Carrier for the First Time
Defining the WLAN Settings of an AP Zone

CAUTION! If you set the encryption algorithm to TKIP, the AP will only be able to
support up to 26 clients. When this limit is reached, additional clients will be unable
to associate with the AP. On the other hand, if you select AES or none, the AP will
be able to support up to 256 clients (less if wireless mesh is also enabled on the
same radio).

WEP Key/Passphrase
• WEP Key: WEP methods only. Click the Hex field, and then type the required
key text. If the key is for WEP 64 encryption, enter ten hexadecimal characters
(any combination of 0-9, A-F). If it is for WEP 128 encryption, enter 26 hexadecimal characters (any combination of 0-9, A-F).
• Passphrase: WPA-PSK methods only. Click in this field and type the text of the
passphrase used for authentication. The passphrase must contain between
eight and 63 characters (or 64 hexadecimal characters).

Authentication & Accounting Service
• Authentication Service: This option appears only when 802.1x EAP is selected
as the authentication method. Select the authentication server that you want to
use for this WLAN. Only AAA servers that you previously added appear here.
• Accounting Service: This option appears only when 802.1x EAP is selected in
Authentication method. Additionally, you must have added a RADIUS
Accounting server previously. Select the RADIUS Accounting server from the
drop-down list, as a proxy for vSCG.

Options
• Wireless Client Isolation: This option appears only when Standard Usage is
selected as the WLAN usage type. Wireless client isolation enables subnet
restrictions for connected clients. Click Enable if you want to prevent wireless
clients associated with the same AP from communicating with each other locally.
The default value is Disable.
• Priority: Set the priority of this WLAN to Low if you would prefer that other WLAN
traffic takes priority. For example, if you want to prioritize internal traffic over guest
WLAN traffic, you can set the priority in the guest WLAN configuration settings
to “Low.” By default, all WLANs are set to high priority.

• Rate Limiting: Rate limiting controls fair access to the network. When enabled,
the network traffic throughput of each network device (client) is limited to the
rate specified in the traffic policy, and that policy can be applied on either the
uplink or downlink.
Toggle the Uplink and/or Downlink drop-down lists to limit the rate at which
WLAN clients upload/download data. The “Disabled” state means rate limiting
is disabled; thus, traffic flows without prescribed limits.
• Access VLAN: By default, all wireless clients associated with APs that the vSCG
is managing are segmented into a single VLAN (with VLAN ID 1). If you want to
tag this WLAN traffic with a different VLAN ID, enter a valid VLAN ID (2-4094) in
the box. Select the Enable Dynamic VLAN check box to allow the vSCG to
assign VLAN IDs on a per-user basis. Before enabling dynamic VLAN, you need
to define on the RADIUS server the VLAN IDs that you want to assign to users.
• Hide SSID: Click this option if you do not want the ID of this WLAN advertised
at any time. This will not affect performance or force the WLAN user to perform
any unnecessary tasks.

Configuring DHCP Option 43

• Proxy ARP: When enabled on a WLAN, the AP provides proxy service for stations
when receiving neighbor discovery packets (for example, ARP requests and
ICMPv6 Neighbor Solicit messages), and acts on behalf of the station in
delivering ARP replies. When the AP receives a broadcast ARP/Neighbor Solicit
request for a known host, the AP replies on behalf of the host. If the AP receives
a request for an unknown host, it forwards the request at the rate limit specified
• Max Clients: Limit the number of clients that can associate with this WLAN per
AP (default is 100). You can also limit the total number of clients that a specific
AP (or radio, on dual radio APs) will manage.
• 802.11d: The 802.11d standard provides specifications for compliance with
additional regulatory domains (countries or regions) that were not defined in the
original 802.11 standard. Enable this option if you are operating in one of these
additional regulatory domains.
• DHCP Option 82: When this option is enabled and an AP receives a DHCP
request from a wireless client, the AP will encapsulate additional information
(such as VLAN ID, AP name, SSID and MAC address) into the DHCP request
packets before forwarding them to the DHCP server. The DHCP server can then
use this information to allocate an IP address to the client from a particular DHCP
pool based on these parameters.
• Client TX/RX Statistics: Select the Ignore statistics from unauthorized clients
check box if you do not want the vSCG to monitor traffic statistics for unauthorized clients.
• Inactivity Timeout: Select the check box and enter a value in minutes (6 to 600
minutes) after which idle clients will be disconnected.
• Client Fingerprinting: If you select this check box, the vSCG will attempt to identify
client devices by their operating system, device type, and host name, if available.
This makes identifying client devices easier on the Dashboard, Monitor and Client
Details pages.
• Disable WLAN: Select this option to disable this WLAN service.

Configuring DHCP Option 43
To enable the vSCG to manage an AP, the AP must be able to locate the vSCG on
the network successfully and register with it. The easiest way to ensure that APs
can successfully locate the vSCG on the network is by configuring DHCP Option
43 on your DHCP server.

Configuring the vSCG Carrier for the First Time
Configuring DHCP Option 43

DHCP Option 43 enables the DHCP server on your network to provide the vSCG
server address – either IP address or FQDN– (specifically, the IP address assigned
to the vSCG’s control plane or cluster plane interface) to DHCP clients, including
APs that are connected to the network.
The procedure for configuring DHCP option 43 varies, depending on the DHCP
server that you are using. Refer to the documentation provided with your DHCP
server software for information on how to configure DHCP option 43.
NOTE: The following procedure describes how to configure DHCP option 43 on a
Linux server (Fedora). If your DHCP server is running on a different platform, refer
to the DHCP server documentation for the relevant instructions.
Follow these steps to configure DHCP option 43 on a Linux server.
1 Log on to your DHCP server via a console terminal (for example, PuTTY).
2 Go to /etc directory.
3 Run vi dhcpd.conf. This command opens the DHCP configuration file for
editing.
4 At the beginning of the DHCP configuration file, insert the following lines:
option space VendorInfo;
option VendorInfo.WSG code 6 = text;
OR
option space VendorInfo;
option VendorInfo.SCG code 6 = text;
CAUTION! Make sure that space characters exist in “6 = text”. Omitting these
space characters could result in AP connectivity issues.
5 Under the subnet section, insert the following lines:
Vendor-option-space VendorInfo;
option VendorInfo.WSG "{control-ip-address-or-fqdn}"
OR
Vendor-option-space VendorInfo;
option VendorInfo.SCG "{control-ip-address-or-fqdn}"

Configuring the vSCG Carrier for the First Time
Configuring DHCP Option 43

NOTE: {control-ip-address-or-fqdn} must be the IP address or FQDN
of the control plane (br0).
Remember to remove the curly brackets ({ }) that enclose the IP addresses or
FQDNs. If the control plane IP addresses are mapped to proper names on the
DNS server, you could also use FQDN host names instead of IP addresses.
The vSCG supports two formats for vendor information:
• Plain IP address or FQDN (for example, 10.2.0.87 or
server.company.com)
• URL-based IP address or FQDN (for example, https://10.2.0.87/
wsg/ap or https://server.company.com/wsg/ap) where
10.2.0.87 or server.company.com is the IP address or FQDN of the
control plane interface, respectively.
Inserting Multiple IP Addresses or URLs
If you want to insert multiple IP addresses or URLs, use any of the following
formats:
• URL format
-

option VendorInfo.WSG "https://10.2.0.87/wsg/
ap,https://10.2.0.88/wsg/ap", or

- option VendorInfo.SCG "https://10.2.0.87/wsg/
ap,https://10.2.0.88/wsg/ap"
• IP address format
-

option VendorInfo.WSG "10.2.0.87,10.2.0.88", or

- option VendorInfo.SCG "10.2.0.87,10.2.0.88"
CAUTION! Take care not to insert any space characters before or after the comma
(,) character that separates the multiple IP addresses or URLs.
6 Save the changes.
7 Restart the DHCP server to apply the new settings.
You have completed configuring DHCP option 43 on a Linux server.

Verifying That Wireless Clients Can Associate with a Managed AP

Verifying That Wireless Clients Can Associate
with a Managed AP
The last step in the vSCG setup process is to verify that APs can register with the
vSCG and that wireless clients can associate with the APs successfully.
Follow these steps to verify that wireless clients can connect to the network.
1 Verify that the vSCG is connected to the backbone network.
2 Physically connect an AP to the same network as the vSCG. If DHCP option 43
was configured correctly, this AP should be able to locate the vSCG on the
network and to register with it successfully.
3 Check the vSCG Dashboard. The AP zone that you created earlier should have
at least one member AP (the AP that you connected to the network in Step 2).
The AP count appears green, which indicates that it is online.
4 Associate a wireless client with the AP. The following describes the procedure if
you are using a Windows-based wireless client.
a In the system tray, right-click the
(Wireless Network Connection) icon, and
then click View Available Wireless Networks.
b In the list of available wireless network, click the wireless network name (SSID)
that you configured on the AP.
c Click Connect.
Your wireless client connects to the wireless network. After the wireless client
connects to the wireless network successfully, the wireless client icon in the
system tray changes to
.
5 Start your web browser, and then enter www.ruckuswireless.com in the
address bar.
If you are able to connect to the Ruckus Wireless website, you have completed
setting up the vSCG on the network. Congratulations!

Ensuring That APs Can Discover the Controller on the Network
Method 1: Perform Auto Discovery of the Controller Using the SmartLicense Server

Method 1: Perform Auto Discovery of the
Controller Using the SmartLicense Server
NOTE: This guide assumes that you have already activated the controller’s licenses
on the SmartLicense server. If you have not activated the controller’s licenses, see
the Virtualized SmartCell Gateway Quick Setup Guide for RuckOS 3.0 for more
information.
The Ruckus Wireless SmartLicense registration server is a cloud-based, HTTPSenabled web server that allows an access point to query information about its parent
controller by sending its serial number and base MAC address.
NOTE: If you do not want to (or cannot) use the cloud-based SmartLicense
registration server, you can install a local version of the registration server (called the
Local License Server). For more information, see the Local License Server User
Guide.
After you ensure that the controller’s licenses have been activated on the SmartLicense server, you only need to connect the AP to the network, ensure that it has
Internet connectivity, and then reboot the AP. Upon reboot, the AP will automatically
attempt to discover its parent controller by sending the following HTTPS query to
ap-registrar.ruckuswireless.com (the SmartLicense server URL):
https://ap-registrar.ruckuswireless.com/
controller?ap_mac=APMAC&ap_serial=APSERIAL
where APMAC is the AP’s MAC address (for example, APMAC: 74:91:1A:20:59:90)
and APSERIAL (for example, APSERIAL: 311003001685) is the AP’s serial number,
both of which are printed on the AP’s product label.
If the AP is unable to discover its parent controller after the first attempt, it will
continue to do so:
• Once every 5 minutes for up to 60 minutes (12 queries)
• Once every hour for the remaining day (23 queries)
• Once every 24-hour for the remaining two weeks (12 queries)
If the AP is still unable to discover its parent controller after two weeks of uptime,
this cloud-based controller discovery method will be disabled permanently. You will
need to reset the AP to factory default settings to re-enable this controller discovery
method.

Ensuring That APs Can Discover the Controller on the Network
Method 2: Perform Auto Discovery on Same Subnet, then Transfer the AP to Intended Subnet

Method 2: Perform Auto Discovery on Same
Subnet, then Transfer the AP to Intended
Subnet
If you are deploying the AP and the controller on different subnets, let the AP perform
auto discovery on the same subnet as the controller before moving the AP to another
subnet. To do this, connect the AP to the same network as the controller. When
the AP starts up, it will discover and attempt to register with the controller. Approve
the registration request if auto approval is disabled. After the AP registers with the
controller successfully, transfer it to its intended subnet. It will be able to find and
communicate with the controller once you reconnect it to the other subnet.
NOTE: If you use this method, make sure that you do not change the IP address
of the controller after the AP discovers and registers with it. If you change the
controller’s IP address, the AP will no longer be able to communicate with it and will
be unable to rediscover it.

Method 3: Register the Controller with the
DNS Server
If you register the controller with your DNS server, supported APs that request IP
addresses from your DHCP server will also obtain DNS related information that will
enable them to discover controllers on the network. Using the DNS information they
obtained during the DHCP request, APs will attempt to resolve the controller IP
address using RuckusController.{DNS domain name} and
zonedirector.{DNS domain name}.
To register the controller with the DNS server, do the following.
1 Open the DNS zone file, and then add two records with the following information:
• Record Key#1: RuckusController
Type: A (IPv4 Domain Name Translation)
Value: (IP address of the controller)
• Record Key#2: zonedirector
Type: A (IPv4 Domain Name Translation)
Value: (IP address of the controller)

3 Open the DHCP configuration file, and then insert the DNS domain name in the
DHCP configuration file. For example, if the DNS domain name is “38.jack”, insert
the following line into the DHCP configuration file:
option domain-name “38.jack”

Method 3: Register the Controller with the DNS Server

Figure 49. Insert option domain-name “38.jack”

4 Save the DHCP configuration file.
When the AP obtains the DNS domain name from the DHCP server (using “Domain
Name option 15” in the DHCP-offer packet), it will resolve
“RuckusController.{domain-name}” and “zonedirector.{domain-name}” through the
DNS server, and then it will obtain the controller’s IP address from the DNS server’s
response.
NOTE: If the AP uses a static IP address or it cannot obtain the DNS domain name
from the DHCP server, the AP will attempt to resolve “RuckusController” and
“zonedirector” without a domain name from the DNS server as the FQDN of
controller's control interface.
You have completed registering the controller with the DNS server.

Method 4: Configure DHCP Option 43 on the DHCP Server

Method 4: Configure DHCP Option 43 on the
DHCP Server
Another method for the AP to discover the controller on the network automatically
is to configure the DHCP server on the network. To do this, you will need to configure
DHCP Option 43 (043 Vendor Specific Info) with the IP address of the controller on
the network. When an AP requests an IP address from the DHCP server, the DHCP
server will send a list of controller IP addresses to the AP. If there are multiple
controller devices on the network, the AP will automatically select a controller to
register with from this list of IP addresses.
DHCP Option 43 enables the DHCP server on your network to provide the
controller’s server address – either IP address or FQDN– (specifically, the IP address
assigned to the controller’s control plane or cluster plane interface) to DHCP clients,
including APs that are connected to the network.
The procedure for configuring DHCP option 43 varies, depending on the DHCP
server that you are using. Refer to the documentation provided with your DHCP
server software for information on how to configure DHCP option 43.
NOTE: The following procedure describes how to configure DHCP option 43 on a
Linux server (Fedora). If your DHCP server is running on a different platform, refer
to the DHCP server documentation for the relevant instructions.
CAUTION! If you have a ZoneDirector controller on the network and you do not
want APs to be managed by this ZoneDirector controller, you must disable auto
approval on the ZoneDirector web interface. Log on to the ZoneDirector web
interface, and then go to Configure > Access Points > Access Points Policies page,
and then clear the Approval check box.
Follow these steps to configure DHCP option 43 on a Linux server.
1 Log on to your DHCP server via a console terminal (for example, PuTTY).
2 Go to /etc directory.
3 Run vi dhcpd.conf. This command opens the DHCP configuration file for
editing.

Method 4: Configure DHCP Option 43 on the DHCP Server

4 At the beginning of the DHCP configuration file, insert the following lines:
option VendorInfo.WSG_sub6 code 6=text;
option VendorInfo.WSG_sub3 code 3=text;
option VendorInfo.WSG_sub6 "";
option VendorInfo.WSG_sub3 "";
For example, if you only have one controller on the network and its IP address
is 120.0.0.3, then these lines in the DHCP configuration file should look like in
Figure 50Sample DHCP Option 43 configuration.
Figure 50. Sample DHCP Option 43 configuration

If you have a two-node controller cluster on the network, use a comma to
separate the control interface IP addresses in option VendorInfo.WSG, for
example:
option VendorInfo.WSG “120.0.0.3,120.0.0.4”
where 120.0.0.3 is the control interface IP address of the first controller and
120.0.0.4 is the control interface IP address of the second controller.
5 Save the DHCP configuration file.
6 Restart the DHCP server to apply the new settings.
7 Verify that the LWAPP2SCG application is enabled on the controller. To verify,
log on to the controller’s CLI, and then enter the following command:
show running-config lwapp2scg
If LWAPP2SCG is enabled, the value for ACL Policy should show as Accept
