1INTRODUCTION
The EliteConnectTM SMCE21011 is an IEEE 802.11n access point (AP) that
meets draft 2.0 standards. It is fully interoperable with older 802.11a/b/g
standards, providing a transparent, wireless high speed data
communication between the wired LAN and fixed or mobile devices. The
unit includes three detachable dual-band 2.4/5 GHz antennas with the
option to attach higher specification external antennas that boost network
coverage.
KEY HARDWARE FEATURES
The following table describes the main hardware features of the AP.
DESCRIPTION OF CAPABILITIES
The SMC21011 supports up to eight Virtual Access Point (VAP) interfaces,
which allow traffic to be separated for different user groups within the
same AP service area. Each VAP can support up to 64 wireless clients,
whereby the clients associate with each VAP in the same way as they would
with physically separate access points. This means that each VAP can be
configured with its own Service Set Identification (SSID), security settings,
VLAN assignments, and other parameters, allowing the AP to serve a
diverse range of client needs in an area from a single unit.

ANTENNAS The access point includes three integrated external MIMO (multiple-input
and multiple-output) antennas. MIMO uses multiple antennas for
transmitting and receiving radio signals to improve data throughput and
link range.
Each antenna transmits the outgoing signal as a toroidal sphere (doughnut
shaped), with the coverage extending most in a direction perpendicular to
the antenna. Therefore, the antennas should be adjusted to an angle that
provides the appropriate coverage for the service area.
EXTERNAL ANTENNA
CONNECTOR
The access point supports external antennas for improving the coverage of
the 802.11n signal. The antennas supplied with the unit screw off in a
clockwise manner and can be replaced with with alternative antennas that
extend or shape the coverage area.

CONSOLE PORT This port is used to connect a console device to the access point through a
serial cable. The console device can be a PC or workstation running a VT-
100 terminal emulator, or a VT-100 terminal. A crossover RJ-45 to RS-232
cable is supplied with the unit for connecting to the console port.
ETHERNET PORT The access point has one 1000BASE-T RJ-45 port that can be attached
directly to 10BASE-T/100BASE-TX/1000BASE-TX LAN segments.
This port supports automatic MDI/MDI-X operation, so you can use
straight-through cables for all network connections to PCs, switches, or
hubs.
The access point appears as an Ethernet node and performs a bridging
function by moving packets from the wired LAN to remote workstations on
the wireless infrastructure.
N
OTE
:
The RJ-45 port also supports Power over Ethernet (PoE) based on
the IEEE 802.3af standard. Refer to the description for the “Power
Connector” for information on supplying power to the access point’s
network port from a network device, such as a switch or power injector,
that provides Power over Ethernet (PoE).
POWER CONNECTOR The access point does not have a power switch. It is powered on when
connected to the AC power adapter, and the power adapter is connected to
a power source. The power adapter automatically adjusts to any voltage
between 100~240 volts at 50 or 60 Hz, and supplies 48 volts DC power to
the unit. No voltage range settings are required.
The access point may also receive Power over Ethernet (PoE) from a switch
or other network device that supplies power over the network cable based
on the IEEE 802.3af standard.
POWER Off Indicates that there is no power or the power
source has been disconnected.
Flashing Green Indicates that the system is rebooting or has
started a reset.
Green Indicates that power is being supplied and the
system is functioning normally.
Red Indicates that there has been a system

2NETWORK TOPOLOGIES
Wireless networks support a standalone configuration as well as an
integrated configuration with 10/100/1000 Mbps Ethernet LANs. The
SMCE21011 also provides bridging services that can be configured
independently on either the 5 GHz or 2.4 GHz radio interfaces.
Access points can be deployed to support wireless clients and connect
wired LANs in the following configurations:
◆Infrastructure for wireless LANs
◆Infrastructure wireless LAN for roaming wireless PCs
◆Infrastructure wireless bridge to connect wired LANs
INTERFERENCE ISSUES
The 802.11b, 802.11g and 802.11n frequency band operating at 2.4 GHz
can easily encounter interference from other 2.4 GHz devices, such as
other 802.11b/g/n wireless devices, cordless phones and microwave
ovens. If you experience poor wireless LAN performance, try the following
measures:
◆Limit any possible sources of radio interference within the service area
◆Increase the distance between neighboring access points
◆Decrease the signal strength of neighboring access points
◆Increase the channel separation of neighboring access points (e.g. up
to 3 channels of separation for 802.11b, or up to 4 channels for
802.11a, or up to 5 channels for 802.11g)
INFRASTRUCTURE WIRELESS LAN
The access point also provides access to a wired LAN for wireless
workstations. An integrated wired/wireless LAN is called an Infrastructure
configuration. A Basic Service Set (BSS) consists of a group of wireless PC
users, and an access point that is directly connected to the wired LAN.
Each wireless PC in this BSS can talk to any computer in its wireless group
via a radio link, or access other computers or network resources in the
wired LAN infrastructure via the access point.

Infrastructure Wireless LAN for Roaming Wireless PCs
– 36 –
The infrastructure configuration extends the accessibility of wireless PCs to
the wired LAN.
A wireless infrastructure can be used for access to a central database, or
for connection between mobile workers, as shown in the following figure.
Figure 7: Infrastructure Wireless LAN
INFRASTRUCTURE WIRELESS LAN FOR ROAMING WIRELESS PCS
The Basic Service Set (BSS) defines the communications domain for each
access point and its associated wireless clients. The BSS ID is a 48-bit
binary number based on the access point’s wireless MAC address, and is
set automatically and transparently as clients associate with the access
point. The BSS ID is used in frames sent between the access point and its
clients to identify traffic in the service area.
The BSS ID is only set by the access point, never by its clients. The clients
only need to set the Service Set Identifier (SSID) that identifies the service
set provided by one or more access points. The SSID can be manually
configured by the clients, can be detected in an access point’s beacon, or
can be obtained by querying for the identity of the nearest access point.
For clients that do not need to roam, set the SSID for the wireless card to
that used by the access point to which you want to connect.
A wireless infrastructure can also support roaming for mobile workers.
More than one access point can be configured to create an Extended
Service Set (ESS). By placing the access points so that a continuous

coverage area is created, wireless users within this ESS can roam freely. All
wireless network cards and adapters and wireless access points within a
specific ESS must be configured with the same SSID.
Figure 8: Infrastructure Wireless LAN for Roaming Wireless PCs
INFRASTRUCTURE WIRELESS BRIDGE
The IEEE 802.11 standard defines a Wireless Distribution System (WDS)
for bridge connections between BSS areas (access points). The access
point uses WDS to forward traffic on links between units.
The access point supports WDS bridge links that are independently
configurable on each VAP. There are two WDS modes; WDS-AP and WDS-
STA. Otherwise, VAPs operate in a normal AP mode.
◆AP Mode: Provides services to clients as a normal access point.
◆WDS-AP Mode: Operates as an access point in WDS mode, which
accepts connections from client stations in WDS mode.
◆WDS-STA Mode: Operates as a client station in WDS mode, which
connects to an access point in WDS mode. The user needs to specify
the MAC address of the access point in WDS mode to which it intends to
connect.

3INSTALLING THE ACCESS POINT
This chapter describes how to install the access point.
LOCATION SELECTION
Choose a proper place for the access point. In general, the best location is
at the center of your wireless coverage area, within line of sight of all
wireless devices. Try to place the access point in a position that can best
cover its service area. For optimum performance, consider these
guidelines:
◆Mount the access point as high as possible above any obstructions in
the coverage area.
◆Avoid mounting next to or near building support columns or other
obstructions that may cause reduced signal or null zones in parts of the
coverage area.
◆Mount away from any signal absorbing or reflecting structures (such as
those containing metal).
The access point can be mounted on any horizontal surface, or a wall.

MOUNTING ON A WALL
To mount on a wall follow the instructions below.
Figure 11: Wall Mounting
The access point should be mounted only to a wall or wood surface that is
at least 1/2-inch plywood or its equivalent. To mount the access point on a
wall, always use its wall-mounting bracket. The access point must be
mounted with the RJ-45 cable connector oriented upwards to ensure
proper operation.
1. Mark the position of the three screw holes on the wall. For concrete or
brick walls, you will need to drill holes and insert wall plugs for the
screws.
2. Insert the included screws into the holes, leaving about 2-3 mm
clearance from the wall.
3. Line up the three mounting points on the AP with the screws in the wall,
then slide the AP down onto the screws until it is in a secured position.

Connecting and Powering On
– 42 –
CONNECTING AND POWERING ON
Connect the power adapter to the access point, and the power cord to an
AC power outlet.
Otherwise, the access point can derive its operating power directly from
the RJ-45 port when connected to a device that provides IEEE 802.3af
compliant Power over Ethernet (PoE).
C
AUTION
:
Use ONLY the power adapter supplied with this access point.
Otherwise, the product may be damaged.
N
OTE
:
If the access point is connected to both a PoE source device and an
AC power source, AC will be disabled.
1. Observe the Self Test – When you power on the access point, verify
that the Power indicator stops flashing and remains on, and that the
other indicators start functioning as described under “LED Indicators”
on page 32.
If the PWR LED does not stop flashing, the self test has not completed
correctly. Refer to “Troubleshooting” on page 241.
2. Connect the Ethernet Cable – The access point can be connected to
a 10/100/1000 Mbps Ethernet through a network device such as a hub
or a switch. Connect your network to the RJ-45 port on the back panel
with Category 5E or better UTP Ethernet cable. When the access point
and the connected device are powered on, the Ethernet Link LED
should light indicating a valid network connection.
N
OTE
:
The RJ-45 port on the access point supports automatic MDI/MDI-X
operation, so you can use straight-through cables for all network
connections to PCs, switches, or hubs.
3. Position the Antennas – Each antenna emits a radiation pattern that
is toroidal (doughnut shaped), with the coverage extending most in the
direction perpendicular to the antenna. Therefore, the antennas should
be oriented so that the radio coverage pattern fills the intended
horizontal space. Also, the antennas should both be positioned along
the same axes, providing the same coverage area. For example, if the
access point is mounted on a horizontal surface, all antennas should be
positioned pointing vertically up to provide optimum coverage.
4. Connect the Console Port – Connect the RJ-45 console cable
(included with access point) to the RS-232 console port for accessing
the command-line interface. You can manage the access point using
the console port, the web interface, or SNMP management software.

IP ADDRESS
Configuring the access point with an IP address expands your ability to
manage the access point. A number of access point features depend on IP
addressing to operate.
You can use the web browser interface to access IP addressing only if the
access point already has an IP address that is reachable through your
network.
By default, the access point will be not be automatically configured with IP
settings from a Dynamic Host Configuration Protocol (DHCP) server. The
default IP address is 192.168.1.1, subnet mask 255.255.255.0 and a
default gateway of 192.168.1.254.
You will first be prompted to enter the primary and secondary DNS address

(WPA) wireless security. A secondary RADIUS server may also be specified
as a backup should the primary server fail or become inaccessible.
In addition, the configured RADIUS server can also act as a RADIUS
Accounting server and receive user-session accounting information from
the access point. RADIUS Accounting can be used to provide valuable
information on user activity in the network.
This guide assumes that you have already configured RADIUS server(s) to

SYSTEM TIME
Simple Network Time Protocol (SNTP) allows the access point to set its
internal clock based on periodic updates from a time server (SNTP or NTP).
Maintaining an accurate time on the access point enables the system log to
record meaningful dates and times for event entries. If the clock is not set,
the access point will only record the time from the factory default set at the
last bootup.
The access point acts as an SNTP client, periodically sending time
synchronization requests to specific time servers. You can configure up to
two time server IP addresses. The access point will attempt to poll each
server in the configured sequence.

◆Secondary Server — The IP address of a secondary SNTP or NTP time
server. The access point first attempts to update the time from the
primary server; if this fails it attempts an update from the secondary
server.
TIME ZONE SETTING SNTP uses Greenwich Mean Time, or GMT (sometimes referred to as
Coordinated Universal Time, or UTC) based on the time at the Earth’s
prime meridian, zero degrees longitude. To display a time corresponding to
your local time, you must indicate the number of hours your time zone is

SPECTRALINK VOICE PRIORITY
SpectraLink Voice Priority (SVP) is a voice priority mechanism for WLANs.
SVP is an open, straightforward QoS approach that has been adopted by
most leading vendors of WLAN APs. SVP favors isochronous voice packets
over asynchronous data packets when contending for the wireless medium
and when transmitting packets onto the wired LAN.
Figure 25: SVP Settings
The following items are displayed on this page:
◆SVP Status — Enables/disables SVP on the access point.
VLAN CONFIGURATION
VLANs (virtual local area networks) are turned off by default when first
installing the access point. If turned on they will automatically tag any
packets received by the WAN port before sending them on to the relevant
VAP (virtual access point).
The access point can employ VLAN tagging support to control access to
network resources and increase security. VLANs separate traffic passing
between the access point, associated clients, and the wired network. There
can be a VLAN assigned to each associated client, a default VLAN for each
VAP (Virtual Access Point) interface, and a management VLAN for the
access point.
Note the following points about the access point’s VLAN support:

VLAN Configuration
– 61 –
◆The management VLAN is for managing the access point through
remote management tools, such as the web interface, SSH, SNMP, or
Telnet. The access point only accepts management traffic that is tagged
with the specified management VLAN ID.
◆All wireless clients associated to the access point are assigned to a
VLAN. If IEEE 802.1X is being used to authenticate wireless clients,
specific VLAN IDs can be configured on the RADIUS server to be
assigned to each client. If a client is not assigned to a specific VLAN or
if 802.1X is not used, the client is assigned to the default VLAN for the
VAP interface with which it is associated. The access point only allows
traffic tagged with assigned VLAN IDs or default VLAN IDs to access
clients associated on each VAP interface.
◆When VLAN support is enabled on the access point, traffic passed to the
wired network is tagged with the appropriate VLAN ID, either an
assigned client VLAN ID, default VLAN ID, or the management VLAN ID.
Traffic received from the wired network must also be tagged with one of
these known VLAN IDs. Received traffic that has an unknown VLAN ID
or no VLAN tag is dropped.
◆When VLAN support is disabled, the access point does not tag traffic
passed to the wired network and ignores the VLAN tags on any received
frames.
N
OTE
:
Before enabling VLAN tagging on the access point, be sure to
configure the attached network switch port to support tagged VLAN frames
from the access point’s management VLAN ID, default VLAN IDs, and other
client VLAN IDs. Otherwise, connectivity to the access point will be lost
when you enable the VLAN feature.
Using IEEE 802.1X and a central RADIUS server, up to 64 VLAN IDs can be
mapped to specific wireless clients, allowing users to remain within the
same VLAN as they move around a campus site. This feature can also be
used to control access to network resources from clients, thereby
improving security.
A VLAN ID (1-4094) can be assigned to a client after successful IEEE
802.1X authentication. The client VLAN IDs must be configured on the
RADIUS server for each user authorized to access the network. If a client
does not have a configured VLAN ID on the RADIUS server, the access
point assigns the client to the configured default VLAN ID for the VAP
interface.

This chapter describes management access settings on the access point. It
includes the following sections:
◆“Remote Management Settings” on page 65
◆“Access Limitation” on page 67
◆“Simple Network Management Protocol” on page 68
REMOTE MANAGEMENT SETTINGS
The Web, Telnet, and SNMP management interfaces are enabled and open
to all IP addresses by default. To provide more security for management
access to the access point, specific interfaces can be disabled and
management restricted to a single IP address or a limited range of IP
addresses.
Once you specify an IP address or range of addresses, access to
management interfaces is restricted to the specified addresses. If anyone
tries to access a management interface from an unauthorized address, the
access point will reject the connection.
Telnet is a remote management tool that can be used to configure the
access point from anywhere in the network. However, Telnet is not secure
from hostile attacks. The Secure Shell (SSH) can act as a secure
replacement for Telnet. The SSH protocol uses generated public keys to
encrypt all data transfers passing between the access point and SSH-
enabled management station clients and ensures that data traveling over
the network arrives unaltered. Clients can then securely use the local user
name and password for access authentication.
Note that SSH client software needs to be installed on the management
station to access the access point for management via the SSH protocol.
Both HTTP and HTTPS service can be enabled independently. If you enable
HTTPS, you must indicate this in the URL: https://device:port_number]
When you start HTTPS, the connection is established in this way:
◆The client authenticates the server using the server’s digital certificate.
◆The client and server negotiate a set of security protocols to use for the
connection.

SIMPLE NETWORK MANAGEMENT PROTOCOL
Simple Network Management Protocol (SNMP) is a communication protocol
designed specifically for managing devices on a network. Equipment
commonly managed with SNMP includes switches, routers and host
computers. SNMP is typically used to configure these devices for proper
operation in a network environment, as well as to monitor them to evaluate
performance or detect potential problems.
Managed devices supporting SNMP contain software, which runs locally on
the device and is referred to as an agent. A defined set of variables, known
as managed objects, is maintained by the SNMP agent and used to manage
the device. These objects are defined in a Management Information Base
(MIB) that provides a standard presentation of the information controlled
by the agent. SNMP defines both the format of the MIB specifications and
the protocol used to access this information over the network.
The access point includes an onboard agent that supports SNMP versions
1, 2c, and 3 clients. This agent continuously monitors the status of the
access point, as well as the traffic passing to and from wireless clients. A
network management station can access this information using SNMP
management software that is compliant with MIB II. To implement SNMP
management, the access point must first have an IP address and subnet
mask, configured either manually or dynamically. Access to the onboard
agent using SNMP v1 and v2c is controlled by community strings. To

VIEW ACCESS
CONTROL MODEL
To configure SNMPv3 management access to the AP, follow these steps:
1. Specify read and write access views for the AP MIB tree.
2. Configure SNMP user groups with the required security model (that is,
SNMP v1, v2c, or v3) and security level (authentication and privacy).
3. Assign SNMP users to groups, along with their specific authentication
and privacy passwords.
Figure 32: SNMP VACM
CREATING VIEWS
SNMPv3 views are used to restrict user access to specified portions of the
MIB tree. The are no predefined views by default.
The following items are displayed on the VACM page.
◆View Name – The name of the SNMP view. (Range: 1-32 characters)
◆Type – Indicates if the object identifier of a branch within the MIB tree
is included or excluded from the SNMP view.
◆OID – Allows you to configure the object identifiers of branches within
the MIB tree. Wild cards can be used to mask a specific portion of the
OID string.

◆Mask (option) – A hexadecimal value with each bit masking the
corresponding ID in the MIB subtree. A “1” in the mask indicates an
exact match and a “0” indicates a “wild card.” For example, a mask
value of 0xFFBF provides a bit mask “1111 1111 1011 1111.” If applied
to the subtree “1.3.6.1.2.1.2.2.1.1.23,” the zero corresponds to the
10th subtree ID. When there are more subtree IDs than bits in the
mask, the mask is padded with ones.
◆View List – Shows the currently configured object identifiers of
branches within the MIB tree that define the SNMP view.
CREATING GROUPS
An SNMPv3 group sets the access policy for its assigned users, restricting
them to specific read, write, and notify views. You can create new groups
to map a set of SNMP users to SNMP views.
◆Group Name – The name of the SNMP group. (Range: 1-32
characters)
◆Security Level – The security level used for the group:
■noAuthNoPriv – There is no authentication or encryption used in
SNMP communications.
■AuthNoPriv – SNMP communications use authentication, but the
data is not encrypted.
■AuthPriv – SNMP communications use both authentication and
encryption.
◆Read View – The configured view for read access. (Range: 1-32
characters)
◆Write View – The configured view for write access. (Range: 1-32

LINK LAYER DISCOVERY PROTOCOL
This page allows you to configure the Link Layer Discovery Protocol (LLDP).
LLDP allows devices in the local broadcast domain to share information
about themselves. LLDP-capable devices periodically transmit information
in messages called Type Length Value (TLV) fields to neighbor devices.
Advertised information is represented in Type Length Value (TLV) format
according to the IEEE 802.1ab standard, and can include details such as
device identification, capabilities and configuration settings.
This information can be used by SNMP applications to simplify
troubleshooting, enhance network management, and maintain an accurate
network topology.

◆Message Transmission Hold Time — Configures the time-to-live
(TTL) value sent in LLDP advertisements as shown in the formula
below. (Range: 2-10; Default: 4)
The time-to-live tells the receiving LLDP agent how long to retain all
information pertaining to the sending LLDP agent if it does not transmit
updates in a timely manner. TTL in seconds is based on the following
rule: (Transmission Interval * Hold time) ? 65536. Therefore, the
default TTL is 4*30 = 120 seconds.
◆Message Transmission Interval (seconds) — Configures the
periodic transmit interval for LLDP advertisements. (Range: 5-32768
seconds; Default: 30 seconds)
This attribute must comply with the following rule: (Transmission
Interval * Hold Time) ? 65536, and Transmission Interval >= (4 *
Delay Interval)
◆ReInitial Delay Time (seconds) — Configures the delay before
attempting to re-initialize after LLDP ports are disabled or the link goes
down. (Range: 1-10 seconds; Default: 2 seconds)
When LLDP is re-initialized on a port, all information in the remote
systems LLDP MIB associated with this port is deleted.
◆Transmission Delay Value (seconds) — Configures a delay between
the successive transmission of advertisements initiated by a change in
local LLDP MIB variables. (Range: 1-8192 seconds; Default: 4 seconds)
The transmit delay is used to prevent a series of successive LLDP
transmissions during a short period of rapid changes in local LLDP MIB
objects, and to increase the probability that multiple, rather than single
changes, are reported in each transmission.
This attribute must comply with the rule: (4 * Delay Interval) ?

8WIRELESS SETTINGS
This chapter describes wireless settings on the access point. It includes the
following sections:
◆“Spanning Tree Protocol (STP)” on page 82
◆“Authentication” on page 85
◆“Radio Settings” on page 89
◆“Virtual Access Points (VAPs)” on page 93
◆“QoS” on page 99
SPANNING TREE PROTOCOL (STP)
The Spanning Tree Protocol (STP) can be used to detect and disable
network loops, and to provide backup links between switches, bridges or
routers. This allows the wireless bridge to interact with other bridging
devices (that is, an STP-compliant switch, bridge or router) in your network
to ensure that only one route exists between any two stations on the
network, and provide backup links which automatically take over when a
primary link goes down.
STP uses a distributed algorithm to select a bridging device (STP-compliant
switch, bridge or router) that serves as the root of the spanning tree
network. It selects a root port on each bridging device (except for the root
device) which incurs the lowest path cost when forwarding a packet from
that device to the root device. Then it selects a designated bridging device
from each LAN which incurs the lowest path cost when forwarding a packet
from that LAN to the root device. All ports connected to designated
bridging devices are assigned as designated ports. After determining the
lowest cost spanning tree, it enables all root ports and designated ports,
and disables all other ports. Network packets are therefore only forwarded
between root ports and designated ports, eliminating any possible network
loops.
Once a stable network topology has been established, all bridges listen for
Hello BPDUs (Bridge Protocol Data Units) transmitted from the root bridge.
If a bridge does not get a Hello BPDU after a predefined interval (Maximum
Age), the bridge assumes that the link to the root bridge is down. This
bridge will then initiate negotiations with other bridges to reconfigure the
network to reestablish a valid network topology.

numeric values indicate higher priority.)
(Default:32768; Range: 0-65535)
◆Max Age — The maximum time (in seconds) a device can wait without
receiving a configuration message before attempting to reconfigure. All
device ports (except for designated ports) should receive configuration
messages at regular intervals. Any port that ages out STP information
(provided in the last configuration message) becomes the designated
port for the attached LAN. If it is a root port, a new root port is selected
from among the device ports attached to the network.
(Default: 20 seconds; Range: 6-40 seconds)
■Minimum: The higher of 6 or [2 x (Hello Time + 1)].
■Maximum: The lower of 40 or [2 x (Forward Delay - 1)]
◆Hello Time — Interval (in seconds) at which the root device transmits
a configuration message. (Default: 2 seconds; Range: 1-10 seconds)
■Minimum: 1
■Maximum: The lower of 10 or [(Max. Message Age / 2) -1]
◆Forwarding Delay — The maximum time (in seconds) this device
waits before changing states (i.e., discarding to learning to forwarding).
This delay is required because every device must receive information
about topology changes before it starts to forward frames. In addition,
each port needs time to listen for conflicting information that would
make it return to a discarding state; otherwise, temporary data loops
might result. (Default: 15 seconds; Range: 4-30 seconds)
■Minimum: The higher of 4 or [(Max. Message Age / 2) + 1]
■Maximum: 30

Range: 1-65535
◆Link Port Priority — Defines the priority used for this port in the
Spanning Tree Protocol. If the path cost for all ports on a switch are the
same, the port with the highest priority (i.e., lowest value) will be
configured as an active link in the spanning tree. This makes a port
with higher priority less likely to be blocked if the Spanning Tree
Protocol is detecting network loops. Where more than one port is
assigned the highest priority, the port with lowest numeric identifier will
be enabled. (Default: 128; Range: 0-240, in steps of 16)

AUTHENTICATION
Wireless clients can be authenticated for network access by checking their
MAC address against the local database configured on the access point, or
by using a database configured on a central RADIUS server. Alternatively,
authentication can be implemented using the IEEE 802.1X network access
control protocol.
The access point can also operate in a 802.1X supplicant mode. This
enables the access point itself and any bridge-connected units to be
authenticated with a RADIUS server using a configured MD5 user name
and password. This mechanism can prevent rogue access points from
gaining access to the network.
You can configure a list of the MAC addresses for wireless clients that are
authorized to access the network. This provides a basic level of
authentication for wireless clients attempting to gain access to the
network. A database of authorized MAC addresses can be stored locally on
the access point or remotely on a central RADIUS server. (Default: Local
MAC)
LOCAL
AUTHENTICATION
Local MAC Authentication – Configures the local MAC authentication
database. The MAC database provides a mechanism to take certain actions
based on a wireless client’s MAC address. The MAC list can be configured to

RADIO SETTINGS
The IEEE 802.11n interfaces include configuration options for radio signal
characteristics and wireless security features.
The access point can operate in two modes, mixed 802.11g/n, or mixed
802.11a/n only. Also note that 802.11g is backward compatible with
802.11b, and 802.11n is backward compatible with both 802.11b/g and
802.11a at slower data transmit rates.
Each radio supports eight virtual access point (VAP) interfaces, referred to
as VAP0 ~ VAP7. Each VAP functions as a separate access point, and can
be configured with its own Service Set Identification (SSID) and security
settings. However, most radio signal parameters apply to both VAP
interfaces. The configuration options are nearly identical, and are therefore
both covered in this section of the manual. Traffic to specific VAPs can be
segregated based on user groups or application traffic. Both VAPs can have
up to 64 wireless clients, whereby the clients associate with these VAPs the
same as they would with a physical access point.
Packets from 802.11n clients are referred to as High Throughput (HT)
Greenfield packets, in other words packets that can be transmitted at rates
of up to 300 Mbps assuming that HT Channel Bandwidth is set to 20/
40Mhz, see HT Channel Bandwidth next page.
802.11b/g packets are referred to as non-HT packets, being transmitted at
lower throughput rates (see Radio Mode). HT mixed format frames contain
a preamble compatible with the non-HT receivers. HT Greenfield frames do
not contain a non-HT compatible part. Support for HT Greenfield format is
optional. An HT station that does not support the reception of an HT
Greenfield format frame must be able to detect that an HT Greenfield

In this case the receiver must decode the high throughput signal (HT-SIG)
in the packet header and determine if the HT-SIG cyclic redundancy check
(CRC) passes. (Default: Mixed)

The following items are displayed on this page:
◆High Throughput Mode — The access point provides a channel
bandwidth of 20 MHz by default giving an 802.11g connection speed of
54 Mbps and a 802.11n connection speed of up to 108 Mbps, and
ensures backward compliance for slower 802.11b devices. Setting the
HT Channel Bandwidth to 40 MHz (sometimes referred to as Turbo
Mode) increases connection speed for 802.11g and 802.11n to 74 Mbps
and 300 Mbps respectively. HT40plus indicates that the secondary
channel is above the primary channel. HT40minus indicates that the
secondary channel is below the primary channel.
(Default: HT20; Range:HT20, HT40PLUS, HT40MINUS)
N
OTE
:
Some 802.11n wireless clients may be capable of transmission rates
of up to 600 Mbps, however the access point will only be able to connect to
them at a maximum transmission rate of 300 Mbps.
◆Radio Channel — The radio channel that the access point uses to
communicate with wireless clients. When multiple access points are
deployed in the same area, set the channel on neighboring access
points at least five channels apart to avoid interference with each other.
For example, you can deploy up to three access points in the same area

using channels 1, 6, 11. Note that wireless clients automatically set the
channel to the same as that used by the access point to which it is
linked. (The supported channels are dependent on the country code
setting.)
◆Auto Channel Select — Selecting Auto Select enables the access point
to automatically select an unoccupied radio channel.
◆Transmit Power — Adjusts the power of the radio signals transmitted
from the access point. The higher the transmission power, the farther
the transmission range. Power selection is not just a trade off between
coverage area and maximum supported clients. You also have to
ensure that high-power signals do not interfere with the operation of
other radio devices in the service area. (Default: Minimum; Range:
min, 12.5%, 25%, 50%, 100%)
◆Maximum Association Client per VAP — The maximum number of
clients that may associate with each VAP is preset top 64.
◆Radio Mode — Defines the radio mode for the VAP interface. (Default:
11n (g compatible); Range: 11n (b&g compatible), 11n)
N
OTE
:
Enabling the access point to communicate with 802.11b/g clients in
both 802.11b/g/n Mixed and 802.11n modes also requires that HT
Operation be set to HT20.
◆Protection Method — Selects between Request to Send (RTS) and
mixed RTS-CTS (clear to send) packet transmission threshold.
◆Preamble Length — The radio preamble (sometimes called a header)
is a section of data at the head of a packet that contains information
that the wireless device and client devices need when sending and
receiving packets. You can set the radio preamble to long or short. A
short preamble improves throughput performance, whereas a long
preamble is required when legacy wireless devices are part of your
network.
◆Beacon Interval (20-1000) — The rate at which beacon signals are
transmitted from the access point. The beacon signals allow wireless
clients to maintain contact with the access point. They may also carry
power-management information. (Range: 20-1000 TUs; Default: 100
TUs)
◆Data Beacon Rate (DTIM) (1-255) — The rate at which stations in
sleep mode must wake up to receive broadcast/multicast
transmissions.
Known also as the Delivery Traffic Indication Map (DTIM) interval, it
indicates how often the MAC layer forwards broadcast/multicast traffic,
which is necessary to wake up stations that are using Power Save
mode. The default value of 2 indicates that the access point will save all
broadcast/multicast frames for the Basic Service Set (BSS) and forward
them after every second beacon. Using smaller DTIM intervals delivers
![](/img.php?id=1097647&img=bg5c.png)
C
HAPTER

broadcast/multicast frames in a more timely manner, causing stations
in Power Save mode to wake up more often and drain power faster.
Using higher DTIM values reduces the power used by stations in Power
Save mode, but delays the transmission of broadcast/multicast frames.
(Range: 1-255 beacons; Default: 1 beacon)
◆RTS Threshold (0-2345) — Sets the packet size threshold at which a
Request to Send (RTS) signal must be sent to a receiving station prior
to the sending station starting communications. The access point sends
RTS frames to a receiving station to negotiate the sending of a data
frame. After receiving an RTS frame, the station sends a CTS (clear to
send) frame to notify the sending station that it can start sending data.
If the RTS threshold is set to 0, the access point always sends RTS
signals. If set to 2347, the access point never sends RTS signals. If set
to any other value, and the packet size equals or exceeds the RTS
threshold, the RTS/CTS (Request to Send / Clear to Send) mechanism
will be enabled.
The access points contending for the medium may not be aware of each
other. The RTS/CTS mechanism can solve this “Hidden Node Problem.”
(Range: 0-2345 bytes: Default: 2345 bytes)
◆Short Guard Interval — The 802.11n draft specifies two guard
intervals: 400ns (short) and 800ns (long). Support of the 400ns GI is
optional for transmit and receive. The purpose of a guard interval is to
introduce immunity to propagation delays, echoes, and reflections to
which digital data is normally very sensitive. Enabling the Short Guard
Interval sets it to 400ns. (Default: Disabled)
◆Aggregate MAC Protocol Data Unit (A-MPDU) — Enables / disables
the sending of this four frame packet header for statistical purposes.
(Default: Enabled)
◆A-MPDU Length Limit (1024-65535) — Defines the A-MPDU length.
(Default: 65535 bytes; Range: 1024-65535 bytes)
◆Aggregate MAC Service Data Unit (A-MSDU) — Enables / disables
the sending of this four frame packet header for statistical purposes.

◆A-MSDU Length Limit (2290-4096) — Defines the A-MSDU length.
(Default: 4096 bytes; Range: 2290-4096 bytes)

VIRTUAL ACCESS POINTS (VAPS)
The access point supports up to eight virtual access point (VAP) interfaces
numbered 0 to 7. Each VAP functions as a separate access point, and can
be configured with its own Service Set Identification (SSID) and security
settings. However, most radio signal parameters apply to all eight VAP
interfaces.
The VAPs function similar to a VLAN, with each VAP mapped to its own
VLAN ID. Traffic to specific VAPs can be segregated based on user groups
or application traffic. Each VAP can have up to 64 wireless clients, whereby
the clients associate with these VAPs the same as they would with a
physical access point.

Figure 49: Configuring VAPs - Common Settings
The following items are common to all three modes:
◆Association Mode — Defines the mode with which the access point
will associate with other clients.
■Open System: The VAP is configured by default as an “open
system,” which broadcasts a beacon signal including the configured
SSID. Wireless clients with an SSID setting of “any” can read the
SSID from the beacon and automatically set their SSID to allow
immediate connection.
■WPA: WPA employs a combination of several technologies to
provide an enhanced security solution for 802.11 wireless networks.
■WPA-PSK: For enterprise deployment, WPA requires a RADIUS
authentication server to be configured on the wired network.
However, for small office networks that may not have the resources
to configure and maintain a RADIUS server, WPA provides a simple
operating mode that uses just a pre-shared password for network
access. The Pre-Shared Key mode uses a common password for
user authentication that is manually entered on the access point
and all wireless clients. The PSK mode uses the same TKIP packet
encryption and key management as WPA in the enterprise,
providing a robust and manageable alternative for small networks.
■WPA2: WPA2 – WPA was introduced as an interim solution for the
vulnerability of WEP pending the ratification of the IEEE 802.11i
wireless security standard. In effect, the WPA security features are
a subset of the 802.11i standard. WPA2 includes the now ratified
802.11i standard, but also offers backward compatibility with WPA.
Therefore, WPA2 includes the same 802.1X and PSK modes of
operation and support for TKIP encryption.
■WPA2-PSK: Clients using WPA2 with a Pre-shared Key are
accepted for authentication.

■WPA-WPA2 Mixed: Clients using WPA or WPA2 are accepted for
authentication.
■WPA-WPA2-PSK-mixed: Clients using WPA or WPA2 with a Pre-
shared Key are accepted for authentication.
◆Encryption Method — Selects an encryption method for the global
key used for multicast and broadcast traffic, which is supported by all
wireless clients.
■WEP: WEP is used as the multicast encryption cipher. You should
select WEP only when both WPA and WEP clients are supported.
■TKIP: TKIP is used as the multicast encryption cipher.
■AES-CCMP: AES-CCMP is used as the multicast encryption cipher.
AES-CCMP is the standard encryption cipher required for WPA2.
◆802.1X — The access point supports 802.1X authentication only for
clients initiating the 802.1X authentication process (i.e., the access
point does not initiate 802.1X authentication). For clients initiating
802.1X, only those successfully authenticated are allowed to access the
network. For those clients not initiating 802.1X, access to the network
is allowed after successful wireless association with the access point.
The 802.1X mode allows access for clients not using WPA or WPA2
security.
◆Pre-Authentication — When using WPA2 over 802.1X, pre-
authentication can be enabled, which allows clients to roam to a new
access point and be quickly associated without performing full 802.1X
authentication. (Default: Disabled)
◆802.1x Reauthentication Time — The time period after which a
connected client must be re-authenticated. During the re-
authentication process of verifying the client’s credentials on the
RADIUS server, the client remains connected the network. Only if re-
authentication fails is network access blocked. (Range: 0-65535
seconds; Default: 0 means disabled)
WIRED EQUIVALENT
PRIVACY (WEP)
WEP provides a basic level of security, preventing unauthorized access to
the network, and encrypting data transmitted between wireless clients and
the access point. WEP uses static shared keys (fixed-length hexadecimal or
alphanumeric strings) that are manually distributed to all clients that want
to use the network.
WEP is the security protocol initially specified in the IEEE 802.11 standard
for wireless communications. Unfortunately, WEP has been found to be
seriously flawed and cannot be recommended for a high level of network
security. For more robust wireless security, the access point provides Wi-Fi
Protected Access (WPA) for improved data encryption and user
authentication.

Setting up shared keys enables the basic IEEE 802.11 Wired Equivalent
Privacy (WEP) on the access point to prevent unauthorized access to the
network.
If you choose to use WEP shared keys instead of an open system, be sure
to define at least one static WEP key for user authentication and data
encryption. Also, be sure that the WEP shared keys are the same for each
client in the wireless network.
Note that all clients share the same keys, which are used for user
authentication and data encryption. Up to four keys can be specified. These
four keys are used for all VAP interfaces on the same radio.
Figure 50: WEP Configuration
The following items are displayed on this page:
◆Key Type – Select the preferred method of entering WEP encryption
keys on the access point and enter up to four keys:
■Hexadecimal: Enter keys as 10 hexadecimal digits (0-9 and A-F)
for 64 bit keys, 26 hexadecimal digits for 128 bit keys, or 32
hexadecimal digits for 152 bit keys (802.11a radio only). This is the
default setting.
■Alphanumeric: Enter keys as 5 alphanumeric characters for 64 bit
keys, 13 alphanumeric characters for 128 bit keys, or 16
alphanumeric characters for 152 bit keys (802.11a radio only).
◆Key Number – Selects the key number to use for encryption for each
VAP interface. If the clients have all four keys configured to the same
values, you can change the encryption key to any of the eight settings
without having to update the client keys. (Default: Key 1)
◆Shared Key Setup – Select 64 Bit, 128 Bit, or 152 Bit key length. Note
that the same size of encryption key must be supported on all wireless
clients. (Default: None)

Key index and type must match that configured on the clients.
In a mixed-mode environment with clients using static WEP keys and WPA,
select WEP transmit key index 2, 3, or 4. The access point uses transmit
key index 1 for the generation of dynamic keys.
QOS
Wireless networks offer an equal opportunity for all devices to transmit
data from any type of application. Although this is acceptable for most
applications, multimedia applications (with audio and video) are
particularly sensitive to the delay and throughput variations that result
from this “equal opportunity” wireless access method. For multimedia
applications to run well over a wireless network, a Quality of Service (QoS)
mechanism is required to prioritize traffic types and provide an “enhanced
opportunity” wireless access method.
The access point implements QoS using the Wi-Fi Multimedia (WMM)
standard. Using WMM, the access point is able to prioritize traffic and
optimize performance when multiple applications compete for wireless
network bandwidth at the same time. WMM employs techniques that are a
subset of the developing IEEE 802.11e QoS standard and it enables the
access point to inter operate with both WMM- enabled clients and other
devices that may lack any WMM functionality.
Access Categories — WMM defines four access categories (ACs): voice,
video, best effort, and background. These categories correspond to traffic
priority levels and are mapped to IEEE 802.1D priority tags (see “WMM
Access Categories” on page 99). The direct mapping of the four ACs to
802.1D priorities is specifically intended to facilitate inter operability with
other wired network QoS policies. While the four ACs are specified for
specific types of traffic, WMM allows the priority levels to be configured to
match any network-wide QoS policy. WMM also specifies a protocol that
access points can use to communicate the configured traffic priority levels
to QoS-enabled wireless clients.

QoS
– 100 –
WMM Operation — WMM uses traffic priority based on the four ACs; Voice,
Video, Best Effort, and Background. The higher the AC priority, the higher
the probability that data is transmitted.
When the access point forwards traffic, WMM adds data packets to four
independent transmit queues, one for each AC, depending on the 802.1D
priority tag of the packet. Data packets without a priority tag are always
added to the Best Effort AC queue. From the four queues, an internal
“virtual” collision resolution mechanism first selects data with the highest
priority to be granted a transmit opportunity. Then the same collision
resolution mechanism is used externally to determine which device has
access to the wireless medium.
For each AC queue, the collision resolution mechanism is dependent on two
timing parameters:
◆AIFSN (Arbitration Inter-Frame Space Number), a number used to
calculate the minimum time between data frames
◆CW (Contention Window), a number used to calculate a random backoff
time
After a collision detection, a backoff wait time is calculated. The total wait
time is the sum of a minimum wait time (Arbitration Inter-Frame Space, or
AIFS) determined from the AIFSN, and a random backoff time calculated
from a value selected from zero to the CW. The CW value varies within a
configurable range. It starts at CWMin and doubles after every collision up
to a maximum value, CWMax. After a successful transmission, the CW
value is reset to its CWMin value.
Figure 51: WMM Backoff Wait Times
For high-priority traffic, the AIFSN and CW values are smaller. The smaller
values equate to less backoff and wait time, and therefore more transmit
opportunities.

throughput, it can also result in a high number of errors when traffic
levels are heavy. (Default: Acknowledge)

11 USING THE COMMAND LINE
INTERFACE
When accessing the management interface for the over a direct connection
to the console port, or via a Telnet connection, the access point can be
managed by entering command keywords and parameters at the prompt.
Using the access point’s command-line interface (CLI) is very similar to
entering commands on a UNIX system.
CONSOLE CONNECTION
To access the access point through the console port, perform these steps:
At the console prompt, enter the user name and password. (The default
user name is “admin” and the default password is “smcadmin”) When the
user name is entered, the CLI displays the “Enterprise AP#” prompt.
Enter the necessary commands to complete your desired tasks.
When finished, exit the session with the “exit” command.
After connecting to the system through the console port, the login screen
displays
EXAMPLE
(none) login: accton
Password:
1 03:47:41 login[2222]: root login on `ttyS0'
Accton#
N
OTE
:
Command examples shown later in this chapter abbreviate the
console prompt to “AP” for simplicity.

| Using the Command Line Interface
Telnet Connection
– 117 –
TELNET CONNECTION
Telnet operates over the IP transport protocol. In this environment, your
management station and any network device you want to manage over the
network must have a valid IP address. Valid IP addresses consist of four
numbers, 0 to 255, separated by periods. Each address consists of a
network portion and host portion. For example, if the access point cannot
acquire an IP address from a DHCP server, the default IP address used by
the access point, 192.168.1.1, consists of a network portion (192.168.1)
and a host portion (1).
To access the access point through a Telnet session, you must first set the
IP address for the access point, and set the default gateway if you are
managing the access point from a different IP subnet. For example:
AP#configure
AP(config)#interface ethernet
AP(if-ethernet)#ip address 10.1.0.1 255.255.255.0 10.1.0.254
AP(if-ethernet)#
If your corporate network is connected to another network outside your
office or to the Internet, you need to apply for a registered IP address.
However, if you are attached to an isolated network, then you can use any
IP address that matches the network segment to which you are attached.
After you configure the access point with an IP address, you can open a
Telnet session by performing these steps.
1. From the remote host, enter the Telnet command and the IP address of
the device you want to access.
2. At the prompt, enter the user name and system password. The CLI will
display the “Enterprise AP#” prompt to show that you are using
executive access mode (i.e., Exec).
3. Enter the necessary commands to complete your desired tasks.
4. When finished, exit the session with the “quit” or “exit” command.
After entering the Telnet command, the login screen displays:
Username: admin
Password:
Enterprise AP#
N
OTE
:
You can open up to four sessions to the device via Telnet.

ENTERING COMMANDS
This section describes how to enter CLI commands.
KEYWORDS AND
ARGUMENTS
A CLI command is a series of keywords and arguments. Keywords identify
a command, and arguments specify configuration parameters. For
example, in the command “show interfaces ethernet,” show and
interfaces are keywords, and ethernet is an argument that specifies the
interface type.
You can enter commands as follows:
◆To enter a simple command, enter the command keyword.
◆To enter commands that require parameters, enter the required
parameters after the command keyword. For example, to set a
password for the administrator, enter:
Enterprise AP(config)#username smith
MINIMUM
ABBREVIATION
The CLI will accept a minimum number of characters that uniquely identify
a command. For example, the command “configure” can be entered as
con. If an entry is ambiguous, the system will prompt for further input.
COMMAND
COMPLETION
If you terminate input with a Tab key, the CLI will print the remaining
characters of a partial keyword up to the point of ambiguity. In the
“configure” example, typing con followed by a tab will result in printing the
command up to “configure.”
GETTING HELP ON
COMMANDS
You can display a brief description of the help system by entering the help
command. You can also display command syntax by following a command
with the “?” character to list keywords or parameters.
SHOWING COMMANDS If you enter a “?” at the command prompt, the system will display the first
level of keywords for the current configuration mode (Exec, Global
Configuration, or Interface). You can also display a list of valid keywords
for a specific command. For example, the command “show ?” displays a
list of possible show commands:
AP: show ?
APmanagement Show management AP information.
authentication Show Authentication parameters.
bridge Show bridge.
config Show current configuration.
event-log Show event log on console.

NEGATING THE EFFECT
OF COMMANDS
For many configuration commands you can enter the prefix keyword “no”
to cancel the effect of a command or reset the configuration to the default
value. For example, the logging command will log system messages to a
host server. To disable logging, specify the no logging command. This
guide describes the negation effect for all applicable commands.
USING COMMAND
HISTORY
The CLI maintains a history of commands that have been entered. You can
scroll back through the history of commands by pressing the up arrow key.
Any command displayed in the history list can be executed again, or first
modified and then executed.
Using the show history command displays a longer list of recently
executed commands.
UNDERSTANDING
COMMAND MODES
The command set is divided into Exec and Configuration classes. Exec
commands generally display information on system status or clear
statistical counters. Configuration commands, on the other hand, modify
interface parameters or enable certain functions. These classes are further
divided into different modes. Available commands depend on the selected
mode. You can always enter a question mark “?” at the prompt to display a

list of the commands available for the current mode. The command classes
and associated modes are displayed in the following table:
EXEC COMMANDS When you open a new console session on an access point, the system
enters Exec command mode. Only a limited number of the commands are
available in this mode. You can access all other commands only from the
configuration mode. To access Exec mode, open a new console session with
the user name “admin.” The command prompt displays as “Enterprise AP#”
for Exec mode.
Username: admin
Password: [system login password]
AP#
CONFIGURATION
COMMANDS
Configuration commands are used to modify access point settings. These
commands modify the running configuration and are saved in memory.
The configuration commands are organized into four different modes:
◆Global Configuration (GC) - These commands modify the system level
configuration, and include commands such as username and
password.
◆Interface-Ethernet Configuration (IC-E) - These commands modify the
Ethernet port configuration, and include command such as dns and ip.
◆Interface-Wireless Configuration (IC-W) - These commands modify the
wireless port configuration of global parameters for the radio, and
include commands such as channel and transmit-power.
◆Interface-Wireless Virtual Access Point Configuration (IC-W-VAP) -
These commands modify the wireless port configuration for each VAP,
and include commands such as ssid and authentication.
To enter the Global Configuration mode, enter the command configure in
Exec mode. The system prompt will change to “Enterprise AP(config)#”
which gives you access privilege to all Global Configuration commands.

PROCESSING
Commands are not case sensitive. You can abbreviate commands and
parameters as long as they contain enough letters to differentiate them
from any other currently available commands or parameters. You can use
the Tab key to complete partial commands, or enter a partial command
followed by the “?” character to display a list of possible matches. You can
also use the following editing keystrokes for command-line processing:

COMMAND USAGE
◆Both HTTP and HTTPS service can be enabled independently.
◆If you enable HTTPS, you must indicate this in the URL:
https://device:port_number]
◆When you start HTTPS, the connection is established in this way:
◆The client authenticates the server using the server’s digital certificate.
◆The client and server negotiate a set of security protocols to use for the
connection.
◆The client and server generate session keys for encrypting and
decrypting data.
◆The client and server establish a secure encrypted connection.

COMMAND USAGE
◆If anyone tries to access a management interface on the access point
from an invalid address, the unit will reject the connection, enter an
event message in the system log, and send a trap message to the trap
manager.
◆IP address can be configured for SNMP, web and Telnet access
respectively. Each of these groups can include up to five different sets
of addresses, either individual addresses or address ranges.
◆When entering addresses for the same group (i.e., SNMP, web or
Telnet), the access point will not accept overlapping address ranges.
When entering addresses for different groups, the access point will
accept overlapping address ranges.
◆You cannot delete an individual address from a specified range. You
must delete the entire range, and reenter the addresses.
◆You can delete an address range just by specifying the start address, or
by specifying both the start address and end address.

16 DHCP RELAY COMMANDS
Dynamic Host Configuration Protocol (DHCP) can dynamically allocate an
IP address and other configuration information to network clients that
broadcast a request. To receive the broadcast request, the DHCP server
would normally have to be on the same subnet as the client. However,
when the access point’s DHCP relay agent is enabled, received client
requests can be forwarded directly by the access point to a known DHCP
server on another subnet. Responses from the DHCP server are returned to

20 802.1X AUTHENTICATION
COMMANDS
The access point supports IEEE 802.1X access control for wireless clients.
This control feature prevents unauthorized access to the network by
requiring an 802.1X client application to submit user credentials for
authentication. Client authentication is then verified by a RADIUS server
using EAP (Extensible Authentication Protocol) before the access point
grants client access to the network. The 802.1X EAP packets are also used
to pass dynamic unicast session keys and static broadcast keys to wireless
clients.
802.1x enable This command configures 802.1X as enabled for wireless clients. Use the
no form to disable 802.1X support.
SYNTAX
802.1x enable

enable - Authenticates clients that initiate the 802.1X
authentication process. Uses standard 802.11 authentication for all

authentication for any station. After successful 802.11 association,
each client is allowed to access the network.
◆802.1X does not apply to the 10/100Base-TX port.

This command sets the maximum time (in seconds) the root device will
wait before changing states (i.e., discarding to learning to forwarding). This
delay is required because every device must receive information about
topology changes before it starts to forward frames. In addition, each port
needs time to listen for conflicting information that would make it return to
the discarding state; otherwise, temporary data loops might result.

COMMAND MODE
Interface Configuration (Ethernet)
COMMAND USAGE
◆DHCP is enabled by default. To manually configure a new IP address,
you must first disable the DHCP client with the no ip dhcp command.
◆You must assign an IP address to this device to gain management
access over the network or to connect the access point to existing IP
subnets. You can manually configure a specific IP address using this
command, or direct the device to obtain an address from a DHCP server
using the ip dhcp command. Valid IP addresses consist of four
numbers, 0 to 255, separated by periods. Anything outside this format
will not be accepted by the configuration program.
EXAMPLE
AP(config)#interface ethernet
Enter Ethernet configuration commands, one per line.
Enterprise AP(if-ethernet)#ip address 192.168.1.2 255.255.255.0 192.168.1.253
AP(if-ethernet)#

COMMAND MODE
Interface Configuration (Ethernet)
COMMAND USAGE
◆You must assign an IP address to this device to gain management
access over the network or to connect the access point to existing IP
subnets. You can manually configure a specific IP address using the ip
address command, or direct the device to obtain an address from a
DHCP server using this command.
◆When you use this command, the access point will begin broadcasting
DHCP client requests. The current IP address (i.e., default or manually
configured address) will continue to be effective until a DHCP reply is
received. Requests will be broadcast periodically by this device in an
effort to learn its IP address. (DHCP values can include the IP address,
subnet mask, and default gateway.)

◆The available channel settings are limited by local regulations, which
determine the number of channels that are available.
◆When multiple access points are deployed in the same area, be sure to
choose a channel separated by at least two channels for 802.11a to
avoid having the channels interfere with each other, and at least five
channels for 802.11b/g. You can deploy up to four access points in the
same area for 802.11a (e.g., channels 36, 56, 149, 165) and three
access points for 802.11b/g (e.g., channels 1, 6, 11).
◆For most wireless adapters, the channel for wireless clients is
automatically set to the same as that used by the access point to which
it is linked.

◆The “min” keyword indicates minimum power.
◆The longer the transmission distance, the higher the transmission
power required. But to support the maximum number of users in an
area, you must keep the power as low as possible. Power selection is
not just a trade off between coverage area and maximum supported
clients. You also have to ensure that high strength signals do not
interfere with the operation of other radio devices in your area.

interval - The rate for transmitting beacon signals.
(Range: 20-1000 milliseconds)
DEFAULT SETTING
100
COMMAND MODE
Interface Configuration (Wireless)
COMMAND USAGE
The beacon signals allow wireless clients to maintain contact with the

dtim-period This command configures the rate at which stations in sleep mode must
wake up to receive broadcast/multicast transmissions.
SYNTAX
dtim-period <interval>
interval - Interval between the beacon frames that transmit
broadcast or multicast traffic. (Range: 1-255 beacon frames)
DEFAULT SETTING
1
COMMAND MODE
Interface Configuration (Wireless)
COMMAND USAGE
◆The Delivery Traffic Indication Map (DTIM) packet interval value
indicates how often the MAC layer forwards broadcast/multicast traffic.
This parameter is necessary to wake up stations that are using Power
Save mode.
◆The DTIM is the interval between two synchronous frames with
broadcast/multicast information. The default value of 2 indicates that
the access point will save all broadcast/multicast frames for the Basic
Service Set (BSS) and forward them after every second beacon.

C
HAPTER
26
| Wireless Interface Commands
– 211 –
◆Using smaller DTIM intervals delivers broadcast/multicast frames in a
more timely manner, causing stations in Power Save mode to wake up
more often and drain power faster. Using higher DTIM values reduces
the power used by stations in Power Save mode, but delays the
transmission of broadcast/multicast frames.
EXAMPLE
AP(if-wireless g)#dtim-period 100
AP(if-wireless g)#
rts-threshold This command sets the packet size threshold at which a Request to Send
(RTS) signal must be sent to the receiving station prior to the sending
station starting communications.
SYNTAX
rts-threshold <threshold>
threshold - Threshold packet size for which to send an RTS.
(Range: 0-2347 bytes)
DEFAULT SETTING
2347
COMMAND MODE
Interface Configuration (Wireless)
COMMAND USAGE
◆If the threshold is set to 0, the access point always sends RTS signals.
If set to 2347, the access point never sends RTS signals. If set to any
other value, and the packet size equals or exceeds the RTS threshold,
the RTS/CTS (Request to Send / Clear to Send) mechanism will be
enabled.
◆The access point sends RTS frames to a receiving station to negotiate
the sending of a data frame. After receiving an RTS frame, the station
sends a CTS frame to notify the sending station that it can start sending
data.
◆Access points contending for the wireless medium may not be aware of
each other. The RTS/CTS mechanism can solve this “Hidden Node”
problem.

The commands described in this section configure parameters for wireless
security on the 802.11a and 802.11g interfaces.
auth This command configures authentication for the VAP interface.
SYNTAX
auth <open-system | shared-key | wpa | wpa-psk | wpa2 |
wpa2-psk | wpa-wpa2-mixed | wpa-wpa2-psk-mixed | >
open-system - Accepts the client without verifying its identity
using a shared key. “Open” authentication means either there is no
encryption (if encryption is disabled) or WEP-only encryption is used
(if encryption is enabled).
shared-key - Authentication is based on a shared key that has
been distributed to all stations.
wpa - Clients using WPA are accepted for authentication.
wpa-psk - Clients using WPA with a Pre-shared Key are accepted
for authentication.
wpa2 - Clients using WPA2 are accepted for authentication.
wpa2-psk - Clients using WPA2 with a Pre-shared Key are
accepted for authentication.

COMMAND MODE
Interface Configuration (Wireless-VAP)
COMMAND USAGE
◆The auth command automatically configures settings for each
authentication type, including encryption, 802.1X, and cipher suite. The
command auth open-system disables encryption and 802.1X.
◆To use WEP shared-key authentication, set the authentication type to
“shared-key” and define at least one static WEP key with the key
command. Encryption is automatically enabled by the command.
◆To use WEP encryption only (no authentication), set the authentication
type to “open-system.” Then enable WEP with the encryption
command, and define at least one static WEP key with the key
command.
◆When any WPA or WPA2 option is selected, clients are authenticated
using 802.1X via a RADIUS server. Each client must be WPA-enabled or
support 802.1X client software. The 802.1X settings (see “802.1X
Authentication Commands” on page 175) and RADIUS server details
(see “RADIUS Client Commands” on page 170) must be configured on
the access point. A RADIUS server must also be configured and be
available in the wired network.
◆If a WPA/WPA2 mode that operates over 802.1X is selected (WPA,
WPA2, WPA-WPA2-mixed, or WPA-WPA2-PSK-mixed), the 802.1X
settings (see “802.1X Authentication Commands” on page 175) and
RADIUS server details (see “RADIUS Client Commands” on page 170)
must be configured. Be sure you have also configured a RADIUS server
on the network before enabling authentication. Also, note that each
client has to be WPA-enabled or support 802.1X client software. A
RADIUS server must also be configured and be available in the wired
network.
◆If a WPA/WPA2 Pre-shared Key mode is selected (WPA-PSK, WPA2-PSK
or WPA-WPA2-PSK-mixed), the key must first be generated and
distributed to all wireless clients before they can successfully associate
with the access point. Use the wpa-preshared-key command to
configure the key (see “key” on page 221 and “transmit-key” on
page 222).
◆WPA2 defines a transitional mode of operation for networks moving
from WPA security to WPA2. WPA2 Mixed Mode allows both WPA and
WPA2 clients to associate to a common VAP interface. When the

encryption cipher suite is set to TKIP, the unicast encryption cipher
(TKIP or AES-CCMP) is negotiated for each client. The access point
advertises it’s supported encryption ciphers in beacon frames and
probe responses. WPA and WPA2 clients select the cipher they support
and return the choice in the association request to the access point. For
mixed-mode operation, the cipher used for broadcast frames is always
TKIP. WEP encryption is not allowed.

◆If you use WEP key encryption option, the access point uses the
transmit key to encrypt multicast and broadcast data signals that it
sends to client devices. Other keys can be used for decryption of data
from clients.
◆When using IEEE 802.1X, the access point uses a dynamic key to
encrypt unicast and broadcast messages to 802.1X-enabled clients.
However, because the access point sends the keys during the 802.1X
authentication process, these keys do not have to appear in the client’s
key list.
◆In a mixed-mode environment with clients using static and dynamic
keys, select transmit key index 2, 3, or 4. The access point uses
transmit key index 1 for the generation of dynamic keys.

aes-ccmp - Use AES-CCMP encryption for the unicast and multicast

DEFAULT SETTING

COMMAND MODE
Interface Configuration (Wireless-VAP)
COMMAND USAGE
◆WPA enables the access point to support different unicast encryption
keys for each client. However, the global encryption key for multicast
and broadcast traffic must be the same for all clients.
◆TKIP provides data encryption enhancements including per-packet key
hashing (i.e., changing the encryption key on each packet), a message
integrity check, an extended initialization vector with sequencing rules,
and a re-keying mechanism. Select TKIP if there are clients in the
network that are not WPA2 compliant.
◆TKIP defends against attacks on WEP in which the unencrypted
initialization vector in encrypted packets is used to calculate the WEP
key. TKIP changes the encryption key on each packet, and rotates not
just the unicast keys, but the broadcast keys as well. TKIP is a
replacement for WEP that removes the predictability that intruders
relied on to determine the WEP key.
◆AES-CCMP (Advanced Encryption Standard Counter-Mode/CBCMAC
Protocol): WPA2 is backward compatible with WPA, including the same
802.1X and PSK modes of operation and support for TKIP encryption.
The main enhancement is its use of AES Counter-Mode encryption with
Cipher Block Chaining Message Authentication Code (CBC-MAC) for
message integrity. The AES Counter-Mode/CBCMAC Protocol (AES-
CCMP) provides extremely robust data confidentiality using a 128-bit
key. The AES-CCMP encryption cipher is specified as a standard
requirement for WPA2. However, the computational intensive
operations of AES-CCMP requires hardware support on client devices.
Therefore to implement WPA2 in the network, wireless clients must be
upgraded to WPA2-compliant hardware.

COMMAND USAGE
◆WPA2 provides fast roaming for authenticated clients by retaining keys
and other security information in a cache, so that if a client roams away
from an access point and then returns reauthentication is not required.
◆When a WPA2 client is first authenticated, it receives a Pairwise Master
Key (PMK) that is used to generate other keys for unicast data
encryption. This key and other client information form a Security
Association that the access point names and holds in a cache. The
lifetime of this security association can be configured with this
command. When the lifetime expires, the client security association
and keys are deleted from the cache. If the client returns to the access
point, it requires full reauthentication.
◆The access point can store up to 256 entries in the PMKSA cache.

29 VLAN COMMANDS
The access point can enable the support of VLAN-tagged traffic passing
between wireless clients and the wired network. Up to 64 VLAN IDs can be
mapped to specific wireless clients, allowing users to remain within the
same VLAN as they move around a campus site.
When VLAN is enabled on the access point, a VLAN ID (a number between
1 and 4094) can be assigned to each client after successful authentication
using IEEE 802.1X and a central RADIUS server. The user VLAN IDs must
be configured on the RADIUS server for each user authorized to access the
network. If a user does not have a configured VLAN ID, the access point
assigns the user to its own configured native VLAN ID.
C
AUTION
:
When VLANs are enabled, the access point’s Ethernet port drops
all received traffic that does not include a VLAN tag. To maintain network
connectivity to the access point and wireless clients, be sure that the
access point is connected to a device port on a wired network that supports
IEEE 802.1Q VLAN tags.
The VLAN commands supported by the access point are listed below.

COMMAND DESCRIPTION
◆When VLANs are enabled, the access point tags frames received from
wireless clients with the VLAN ID configured for each client on the
RADIUS server. If the VLAN ID has not been configured for a client on
the RADIUS server, then the frames are tagged with the access point’s
native VLAN ID.
◆Traffic entering the Ethernet port must be tagged with a VLAN ID that
matches the access point’s native VLAN ID, or with a VLAN tag that
matches one of the wireless clients currently associated with the access
point.

30 WMM COMMANDS
The access point implements QoS using the Wi-Fi Multimedia (WMM)
standard. Using WMM, the access point is able to prioritize traffic and
optimize performance when multiple applications compete for wireless
network bandwidth at the same time. WMM employs techniques that are a
subset of the developing IEEE 802.11e QoS standard and it enables the
access point to inter-operate with both WMM- enabled clients and other
devices that may lack any WMM functionality.
The WMM commands supported by the access point are listed below.
wmm This command sets the WMM operational mode on the access point. Use
the no form to disable WMM.
SYNTAX

COMMAND MODE
Interface Configuration (Wireless)
COMMAND USAGE
◆WMM defines four access categories (ACs) – voice, video, best effort,
and background. These categories correspond to traffic priority levels
and are mapped to IEEE 802.1D priority tags (see Table 6-1). The
direct mapping of the four ACs to 802.1D priorities is specifically
intended to facilitate interpretability with other wired network QoS
policies. While the four ACs are specified for specific types of traffic,
WMM allows the priority levels to be configured to match any network-
wide QoS policy. WMM also specifies a protocol that access points can
use to communicate the configured traffic priority levels to QoS-
enabled wireless clients.
◆Although turning off the requirement for the sender to wait for an
acknowledgement can increases data throughput, it can also result in a
high number of errors when traffic levels are heavy.

levels and are mapped to IEEE 802.1D priority tags as shown in
Table 6-1. (Range: 0-3)
LogCwMin - Minimum log value of the contention window. This is the
initial upper limit of the random backoff wait time before wireless
medium access can be attempted. The initial wait time is a random
value between zero and the LogCwMin value. Specify the LogCwMin
value. Note that the LogCwMin value must be equal or less than the
LogCwMax value. (Range: 1-15 microseconds)
LogCwMax - Maximum log value of the contention window. This is
the maximum upper limit of the random backoff wait time before
wireless medium access can be attempted. The contention window
is doubled after each detected collision up to the LogCwMax value.
Note that the CWMax value must be greater or equal to the
LogCwMin value. (Range: 1-15 microseconds)
AIFS - Arbitrary InterFrame Space specifies the minimum amount of
wait time before the next data transmission attempt. (Range: 1-
15 microseconds)
TXOPLimit - Transmission Opportunity Limit specifies the maximum
time an AC transmit queue has access to the wireless medium.
When an AC queue is granted a transmit opportunity, it can transmit
data for a time up to the TxOpLimit. This data bursting greatly
improves the efficiency for high data-rate traffic. (Range: 0-65535

■If MAC address filtering is enabled, be sure the client’s address is
included in the local filtering database or on the RADIUS server
database.
■If the wireless clients are roaming between access points, make
sure that all the access points and wireless devices in the Extended
Service Set (ESS) are configured to the same SSID, and
authentication method.
2. If the access point cannot be configured using the Telnet, a web
browser, or SNMP software:
■Be sure to have configured the access point with a valid IP address,
subnet mask and default gateway.
■If VLANs are enabled on the access point, the management station
should be configured to send tagged frames with a VLAN ID that
matches the access point’s management VLAN (default VLAN 1,
page 17). However, to manage the access point from a wireless
client, the AP Management Filter should be disabled (page 17).
■Check that you have a valid network connection to the access point
and that the Ethernet port or the wireless interface that you are
using has not been disabled.
■If you are connecting to the access point through the wired Ethernet
interface, check the network cabling between the management
station and the access point. If you are connecting to access point
from a wireless client, ensure that you have a valid connection to
the access point.
■If you cannot connect using Telnet, you may have exceeded the
maximum number of concurrent Telnet sessions permitted (i.e, four
sessions). Try connecting again at a later time.
3. If you cannot access the on-board configuration program via a serial
port connection:
■Be sure you have set the terminal emulator program to VT100
compatible, 8 data bits, 1 stop bit, no parity and 9600 bps.
■Check that the null-modem serial cable conforms to the pin-out
connections provided on page B-3.
4. If you forgot or lost the password:
■Set the access point to its default configuration by pressing the
reset button on the back panel for 5 seconds or more. Then use the
default user name “admin” and password “smcadmin” to access the
management interface.
5. If all other recovery measure fail, and the access point is still not
functioning properly, take any of these steps:

CCABLES AND PINOUTS
TWISTED-PAIR CABLE ASSIGNMENTS
For 10/100BASE-TX connections, a twisted-pair cable must have two pairs
of wires. For 1000BASE-T connections the twisted-pair cable must have
four pairs of wires. Each wire pair is identified by two different colors. For
example, one wire might be green and the other, green with white stripes.
Also, an RJ-45 connector must be attached to both ends of the cable.
N

:
DO NOT plug a phone jack connector into the RJ-45 port. Use
only twisted-pair cables with RJ-45 connectors that conform with FCC
standards.
The following figure illustrates how the pins on the RJ-45 connector are

10/100BASE-TX PIN ASSIGNMENTS
Use unshielded twisted-pair (UTP) or shielded twisted-pair (STP) cable for
RJ-45 connections: 100-ohm Category 3 or better cable for 10 Mbps
connections. Also be sure that the length of any twisted-pair connection
does not exceed 100 meters (328 feet).
The RJ-45 port on the access point supports automatic MDI/MDI-X
operation, so you can use straight-through or crossover cables for all
network connections to PCs, switches, or hubs. In straight-through cable,
pins 1, 2, 3, and 6, at one end of the cable, are connected straight through
to pins 1, 2, 3, and 6 at the other end of the cable.
STRAIGHT-THROUGH WIRING
If the twisted-pair cable is to join two ports and only one of the ports has
an internal crossover (MDI-X), the two pairs of wires must be straight-
through. (When auto-negotiation is enabled for any RJ-45 port on this
switch, you can use either straight-through or crossover cable to connect
to any device type.)
You must connect all four wire pairs as shown in the following diagram to
support Gigabit Ethernet connections.

1000BASE-T operation, all four pairs of wires are used for both transmit
and receive.
Use 100-ohm Category 5, 5e or 6 unshielded twisted-pair (UTP) or shielded
twisted-pair (STP) cable for 1000BASE-T connections. Also be sure that the
length of any twisted-pair connection does not exceed 100 meters (328
feet).
CABLE TESTING FOR
EXISTING CATEGORY 5
CABLE
Installed Category 5 cabling must pass tests for Attenuation, Near-End
Crosstalk (NEXT), and Far-End Crosstalk (FEXT). This cable testing
information is specified in the ANSI/TIA/EIA-TSB-67 standard. Additionally,
cables must also pass test parameters for Return Loss and Equal-Level Far-
End Crosstalk (ELFEXT). These tests are specified in the ANSI/TIA/EIA-
TSB-95 Bulletin, “The Additional Transmission Performance Guidelines for
100 Ohm 4-Pair Category 5 Cabling.”
Note that when testing your cable installation, be sure to include all patch
cables between switches and end devices.
ADJUSTING EXISTING
CATEGORY 5 CABLING
TO RUN 1000BASE-T
If your existing Category 5 installation does not meet one of the test
parameters for 1000BASE-T, there are basically three measures that can be
applied to try and correct the problem:
1. Replace any Category 5 patch cables with high-performance Category
5e or Category 6 cables.

ACCESS POINT An internetworking device that seamlessly connects wired and wireless
networks. Access points attached to a wired network, support the creation
of multiple radio cells that enable roaming throughout a facility.
ADVANCED ENCRYPTION
STANDARD (AES)
An encryption algorithm that implements symmetric key cryptography. AES
provides very strong encryption using a completely different ciphering
algorithm to TKIP and WEP.
AUTHENTICATION The process to verify the identity of a client requesting network access.
IEEE 802.11 specifies two forms of authentication: open system and
shared key.
BACKBONE The core infrastructure of a network. The portion of the network that
transports information from one central location to another central location
where it is unloaded onto a local system.
BEACON A signal periodically transmitted from the access point that is used to
identify the service set, and to maintain contact with wireless clients.
BROADCAST KEY Broadcast keys are sent to stations using dynamic keying. Dynamic
broadcast key rotation is often used to allow the access point to generate a
random group key and periodically update all key-management capable
wireless clients.

MAC ADDRESS The physical layer address used to uniquely identify network nodes.
NETWORK TIME
PROTOCOL (NTP)
NTP provides the mechanisms to synchronize time across the network. The
time servers operate in a hierarchical-master-slave configuration in order
to synchronize local clocks within the subnet and to national time
standards via wire or radio.
OPEN SYSTEM A security option which broadcasts a beacon signal including the access
point’s configured SSID. Wireless clients can read the SSID from the
beacon, and automatically reset their SSID to allow immediate connection
to the nearest access point.
ORTHOGONAL
FREQUENCY DIVISION
MULTIPLEXING (ODFM)
OFDM allows multiple users to transmit in an allocated band by dividing the
bandwidth into many narrow bandwidth carriers.
REPEATER AND BRIDGE Repeater and bridge can provide an extended link to a remote access point
from the wired LAN. Access Point working in this mode could connect to
another AP in Access Point mode or Repeater and Bridge mode. Whenever
there are two APs having wireless link together (one in Access Point or
Repeater and Bridge mode, another using Repeater and Bridge mode), and
also have wired link separately, these two APs are also working as
.bridging. for the two wired links.
SERVICE SET IDENTIFIER
(SSID)
An identifier that is attached to packets sent over the wireless LAN and
functions as a password for joining a particular radio cell; i.e., Basic Service
Set (BSS).
SESSION KEY Session keys are unique to each client, and are used to authenticate a
client connection, and correlate traffic passing between a specific client and
the access point.
SHARED KEY A shared key can be used to authenticate each client attached to a wireless
network. Shared Key authentication must be used along with the 802.11
Wireless Equivalent Privacy algorithm.
SIMPLE NETWORK TIME
PROTOCOL (SNTP)
SNTP allows a device to set its internal clock based on periodic updates
from a Network Time Protocol (NTP) server. Updates can be requested from
a specific NTP server, or can be received via broadcasts sent by NTP
servers.

the problems of WEP static keys by dynamically changing data encryption
keys.
TRIVIAL FILE TRANSFER
PROTOCOL (TFTP)
A TCP/IP protocol commonly used for software downloads.
VIRTUAL ACCESS POINT
(VAP)
Virtual AP technology multiplies the number of Access Points present within
the RF footprint of a single physical access device. With Virtual AP
technology, WLAN users within the device.s footprint can associate with
what appears to be different access points and their associated network
services. All the services are delivered using a single radio channel,
enabling Virtual AP technology to optimize the use of limited WLAN radio
spectrum.
