Section I
Getting Started
This section provides an overview of the access point, and introduces some basic
concepts about wireless networking. It also describes the basic settings required to
access the management interface.
This section includes these chapters:
◆
“Introduction” on page 16
◆
“Initial Configuration” on page 22
– 15 –
1
Introduction
The access point (AP) runs software that includes a network management agent.
The agent offers a variety of management options, including SNMP and a webbased interface. A PC may also be connected directly to the AP’s console port for
configuration using a command line interface (CLI).
Configuration Options
The AP’s HTTP web agent allows you to configure AP parameters, monitor wireless
connections, and display statistics using a standard web browser such as Internet
Explorer 6.x or above, and Mozilla Firefox 3.6.2/4/5. The AP’s web management
interface can be accessed from any computer attached to the network.
The CLI program can be accessed by a direct connection to the RS-232 serial
console port on the AP, or remotely by a Telnet or Secure Shell (SSH) connection
over the network.
The AP’s management agent also supports SNMP (Simple Network Management
Protocol). This SNMP agent permits the AP to be managed from any computer in
the network using network management software.
The AP’s web interface, console interface, and SNMP agent allow you to perform
management functions such as:
◆
Set management access user names and passwords
◆
Configure IP settings
◆
Configure SNMP parameters
◆
Configure 2.4 GHz and 5 GHz radio settings
◆
Control access through wireless security settings
◆
Filter packets using Access Control Lists (ACLs)
◆
Upload and download system firmware or configuration files
◆
Display system information and statistics

Chapter 1 | Introduction
Console Port Connection
Console Port Connection
The AP provides an RS-232 serial console port that enables a connection to a PC or
terminal for monitoring and configuring the AP. A null-modem console cable is
provided with the AP.
Attach a VT100-compatible terminal, or a PC running a terminal emulation program
to the AP. You can use the console cable provided with this package, or use a nullmodem cable that complies with the wiring assignments shown in the Installation
Guide.
To connect a terminal to the console port, complete the following steps:
1. Connect the console cable to the serial port on a terminal, or a PC running
terminal emulation software, and tighten the captive retaining screws on the
DB-9 connector.
2. Connect the other end of the cable to the console port on the AP.
3. Make sure the terminal emulation software is set as follows:
■
Select the appropriate serial port (COM port 1 or COM port 2).
■
Set the baud rate to 115200 bps.
■
Set the data format to 8 data bits, 1 stop bit, and no parity.
■
Set flow control to none.
■
Set the emulation mode to VT100.
■
When using HyperTerminal, select Terminal keys, not Windows keys.
Note: Once you have set up the terminal correctly, the console login screen will be
displayed.
For a description of how to use the CLI, see “Using the Command Line Interface” on
page 111. For a list of all the CLI commands, refer to “Index of CLI Commands” on
page 282.
Console Login Access to the CLI is controlled by user names and passwords. The AP has a default
user name and password. To log into the CLI using the default user name and
password, perform these steps:
1. To initiate your console connection, press . The “User Access
Verification” procedure starts.
– 17 –
Chapter 1 | Introduction
Network Connections
2. At the login prompt, enter “admin.”
3. At the Password prompt, press . There is no default password.
4. The session is opened and the CLI displays the “EC#” prompt indicating you
have access to the CLI commands.
Example
(none) login: admin
Password:
Jan 1 11:33:13 login[1918]: root login on 'ttyS0'
EC#
Network Connections
Prior to accessing the AP’s management agent through a network connection, you
must first configure it with a valid IP address, subnet mask, and default gateway
using a console connection, or the DHCP protocol.
The AP has a static default management IPv4 address of 192.168.1.10 and a subnet
mask of 255.255.255.0.
Once the AP’s IP settings are configured for the network, you can access the AP’s
management agent from anywhere within the attached network. The
management agent can be accessed using Telnet from any computer attached to
the network. The AP can also be managed by any computer using a web browser,
or from a network computer using SNMP network management software.
Connecting to the Web Interface
The AP offers a user-friendly web-based management interface for the
configuration of all the unit’s features. Any PC directly attached to the unit can
access the management interface using a web browser, such as Internet Explorer
(version 6.x or above) or Firefox (version 2.x or above).
You may want to make initial configuration changes by connecting a PC directly to
the AP’s LAN port. The AP has a default management IP address of 192.168.1.10 and
a subnet mask of 255.255.255.0. You must set your PC IP address to be on the same
subnet as the AP (that is, the PC and AP addresses must both start 192.168.1.x).
To access the AP’s web management interface, follow these steps:
1. Use your web browser to connect to the management interface using the
default IP address of 192.168.1.10.

Connecting to the Web Interface
2. Log into the interface by entering the default username “admin” with no
password, then click Login.
Note: It is strongly recommended to change the default user name and password
the first time you access the web interface. For information on changing user
names and passwords, See “Administration Settings” on page 32.

Initial Configuration
The AP’s initial configuration steps can be made through the CLI or web browser
interface. If the AP is not configured with an IP address that is compatible with your
network. You can first use the command line interface (CLI) as described below to
configure a valid IP address.
CLI Initial Configuration Steps
First connect to the AP’s console port and log in to the CLI, as described in “Console
Port Connection” on page 17. Then proceed with the required configuration.
Setting an IP Address If the default IP address is not compatible with your network or a DHCP server is not
available, the AP’s IP address must be configured manually using the CLI.
Type “configure” to enter configuration mode, then type “interface ethernet” to
access the Ethernet interface-configuration mode.
#configure
(config)#interface ethernet
(config-if)#
First type “no ip dhcp” to disable DHCP client mode. Then type “ip address ipaddress netmask gateway,” where “ip-address” is the access point’s IP address,
“netmask” is the network mask for the network, and “gateway” is the default
gateway router. Check with your system administrator to obtain an IP address that
is compatible with your network.
(if-ethernet)#no ip dhcp
(if-ethernet)#ip address 192.168.2.2 255.255.255.0 192.168.2.254
(if-ethernet)#
After configuring the access point’s IP parameters, you can access the management
interface from anywhere within the attached network. The command line interface
can also be accessed using Telnet from any computer attached to the network.
Note: Command examples later in this manual show the console prompt as “AP”.
– 22 –
Chapter 2 | Initial Configuration
CLI Initial Configuration Steps
Setting a Password If you are logging in to the CLI for the fist time, you should define management
access passwords for an administrator and guest (used for CLI and web
management), record them, and then keep them in a safe place.
Note: If you loose your management access passwords, you will need to use the
Reset button on the AP to set the configuration back to factory default values.
Passwords can consist of 5 to 32 alphanumeric characters and are case sensitive. To
prevent unauthorized access to the AP, set the passwords as follows:
Open the console interface to access the CLI prompt. Type “configure” and press
. Type “password admin null password,” where “null” is the default old
password, and “password” is your new password. Press .
Example
AP#configure
AP(config)#password admin null tpschris
AP(config)#
Setting the Country You must set the country code of the AP to be sure that the radios operate
Code according to permitted local regulations. That is, setting the country code restricts
operation of the AP to the radio channels and transmit power levels permitted for
wireless networks in the specified country.
Caution: You must set the country code to the country of operation. Setting the
country code ensures that the radios operate within the local regulations specified
for wireless networks.
Note: The country code selection is for non-US models only and is not available to
all US models. Per FCC regulation, all Wi-Fi products marketed in the US must be
fixed to US operation channels only.
From the CLI prompt, type “country ?” to display the list of country codes. Select the
code for your country, and enter the command again, following by your country
code (for example., “tw” for Taiwan).

Security
◆
◆
Association Mode — Defines the mode with which the VAP will associate with
clients. (For more information on security modes, see “Wireless Security
Settings” on page 68.)
■
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: 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. AESCCMP is the standard encryption cipher required for WPA2.

Authentication
◆
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)
Note: When 802.1X is enabled, be sure to configure RADIUS server details. For
more information, see “Primary and Secondary RADIUS Server Setup” on page 76.

IPv4 Address
Caution: You must set the country code to the country of operation. Setting the
country code restricts operation of the AP to the radio channels and transmit
power levels permitted for wireless networks in the specified country.
IPv4 Address
Configuring the AP with an IPv4 address expands your ability to manage the AP. A
number of the AP’s features depend on IPv4 addressing to operate.
You can use the web browser interface to access IPv4 addressing only if the access
point already has an IPv4 address that is reachable through your network.
By default, the AP will be not be automatically configured with IPv4 settings from a
Dynamic Host Configuration Protocol (DHCP) server. The default IPv4 address for
management access is 192.168.1.10, with a subnet mask 255.255.255.0.

IPv6 Address
This section describes how to configure an IPv6 interface for management access
over the network. This AP supports both IPv4 and IPv6, and can be managed
through either of these address types.
By default, the AP will be not be automatically configured with IPv6 settings from a
DHCPv6 server. The default IPv6 address is 2001:db8::1, subnet mask 64 and a
default gateway of 2001:db8::2.

(Default: 2001:db8::1)
◆
Subnet Mask — Indicates the local subnet mask. (Default: 64)
◆
Default Gateway — The default gateway is the IPv6 address of the router for
the access point, which is used if the requested destination address is not on
the local subnet.
If you have management stations, DNS, RADIUS, or other network servers
located on another subnet, type the IPv6 address of the default gateway router
in the text field provided.
◆
Primary and Secondary DNS Address — The IPv6 address of Domain Name
Servers on the network. A DNS maps numerical IPv6 addresses to domain
names and can be used to identify network hosts by familiar names instead of
the IPv6 addresses.
If you have one or more DNS servers located on the local network, type the IPv6
addresses in the text fields provided.
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.

System Time
Figure 12: SNTP Settings
SNTP Server Settings Configures the access point to operate as an SNTP client. When enabled, at least
one time server IP address must be specified.
◆
SNTP Status — Enables/disables SNTP. (Default: enabled)
◆
Primary Server — The IP address of an SNTP or NTP time server that the access
point attempts to poll for a time update.
◆
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 located before (east) or after (west)
GMT.
◆
Time Zone — Select from the scroll down list the locale you are situated most
close to, for example for New York, select ‘(GMT-05) Eastern Time (US & Canada)’.
Daylight Saving The access point provides a way to automatically adjust the system clock for
Settings Daylight Savings Time changes. To use this feature you must define the month and
date to begin and to end the change from standard time. During this period the
system clock is set back by one hour.
◆
Daylight Saving Status — Enalbes/disables daylight savings time. (Default:
disabled)
When enabled, set the month, day, and week to start and stop the daylight
savings time.

VLAN Configuration
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
LAN 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 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:
◆
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.
Wireless clients are assigned to the default VLAN for the VAP interface with
which they are associated. The access point only allows traffic tagged with
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 a VAP 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.
Note: 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 and default VLAN IDs. Otherwise, connectivity to the
access point will be lost when you enable the VLAN feature.

Bridge STP Configuration
The Bridge menu enables configuration of the Spanning Tree Protocol (STP) and
the address table aging time.
Spanning Tree The Spanning Tree Protocol (STP) can be used to detect and disable network loops,
Protocol (STP) 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.

Priority — Used in selecting the root device, root port, and designated port.
The device with the highest priority becomes the STP root device. However, if
all devices have the same priority, the device with the lowest MAC address will
then become the root device. (Note that lower 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

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;

cost takes precedence over port priority.) (Default: 4; 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

Remote Management Settings
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.
◆
The client and server generate session keys for encrypting and decrypting data.

Local Bridge Filter
The access point can employ network traffic frame filtering to control access to
network resources and increase security. You can prevent communications
between wireless clients and prevent access point management from wireless
clients. Also, you can block specific Ethernet traffic from being forwarded by the
access point.
The Local Bridge Filter sets the global mode for wireless-to-wireless
communications between clients associated to Virtual AP (VAP) interfaces on the
access point. (Default: Disabled)

Link Layer Discovery Protocol
◆
Disabled — All clients can communicate with each other through the access
point.
◆
Prevent Intra VAP client communication — When enabled, clients associated
with a specific VAP interface cannot establish wireless communications with
each other. Clients can communicate with clients associated to other VAP
interfaces.
◆
Prevent Inter and Intra VAP client communication — When enabled, clients
cannot establish wireless communications with any other client, either those
associated to the same VAP interface or any other VAP interface.
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.

Link Layer Discovery Protocol
◆
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) ≤ Transmission
Interval

Link Integrity
Link Integrity
The AP provides a link integrity feature that can be used to ensure that wireless
clients are connected to resources on the wired network. The AP does this by
periodically sending Ping messages to a host device in the wired Ethernet network.
If the AP detects that the connection to the host has failed, it can disable the radio
interfaces, forcing clients to find and associate with another AP. When the
connection to the host is restored, the AP re-enables the radio interfaces.
Figure 25: Link Integrity
The following items are displayed on this page:
◆
Link Integrity — Enables the feature. (Default: Disabled)
◆
Destination IP — The link host IP address on the wired network to which Ping
messages are sent. (Default: 192.168.2.254)
◆
Detect Interval — The interval time between each Ping sent to the host IP
address.(Range: 10-86400 seconds; Default: 60 seconds)
◆
Response Timeout — The time to wait for a response to a Ping message.
(Range: 1-10 seconds; Default: 2 seconds)
◆
Retry Count if no response — The number of consecutive failed Ping counts
before the link is determined as lost. (Range: 1-99; Default: 5)
◆
Link Fail Action — When a link integrity test fails you can optionally disable
either radio interface. Note that the shutdown action does not apply for a VAP
interface set to WDS station mode. (Default: Disabled)

Radio Settings
The IEEE 802.11n wireless interfaces include configuration options for radio signal
characteristics and wireless security features.
The AP can operate in several radio modes, mixed 802.11b/g/n (2.4 GHz), or mixed
802.11a/n (5 GHz). Note that the radios can operate at 2.4 GHz and 5 GHz at the
same time. The web interface identifies the radio configuration pages as:
◆
Radio 0 — the 2.4 GHz 802.11b/g/n radio interface
◆
Radio 1 — the 5 GHz 802.11a/n radio interface
Each radio supports 16 virtual access point (VAP) interfaces, referred to as VAP 0 ~
VAP 15. 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 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. The
clients associate with each VAP in the same way as they would with separate
physical access points. The AP supports up to a total of 127 wireless clients across
all VAP interfaces per radio.

Chapter 6 | Wireless Settings
Radio Settings
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 increases connection speed for 802.11n up to 300 Mbps. 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)
◆
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, for 11g/n
HT20 mode 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 available
channels are dependent on the Radio Mode, High Throughput Mode, and
Country Code settings.)
◆
Auto Channel — Selecting Auto Select enables the access point to
automatically select an unoccupied radio channel.
◆
Interference Channel Recover — Rescans all channels when interference is
detected on the current channel, and then changes to a clear channel.
(Default: Disabled)
◆
Wlandev Interference Detection — Enables the detection of nearby APs that
are using the same channel. If the RSSI signal strength of a nearby AP is above
the configured threshold value, the unit switches to another channel.
(Default: Disabled)
◆
Wlandev Interference Detection RSSI —The RSSI signal strength threshold of
a nearby AP above which the unit switches to another channel. (Range: 1-100;
Default: 80)
◆
Wlandev Interference Detection Time —The time duration that a nearby AP
with an RSSI above the set threshold is continuously detected before the unit
restarts the scan process. (Range: 10-300 seconds; Default: 30 seconds)
◆
Antenna — Sets the antenna options for this AP to “system default.”
◆
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.
(Range - Percentage mode: min, 12.5%, 25%, 50%, 100%; Default: 100%)
(Range - dBm mode: 3-20 dBm; Default: 18 dBm)

Chapter 6 | Wireless Settings
Radio Settings
◆
Maximum Association Clients — The total maximum number of clients that
may associate with the radio. (Range: 1-127; Default: 100)
◆
Radio Mode — Defines the radio operation mode.
■
Radio 0 (2.4 GHz Radio) — Default: 11n (g compatible); Options: 11n (b&g
compatible), 11n (g compatible).
■
Radio 1 (5 GHz Radio) — Default: 11n; Options: 11n (a compatible), 11n.
Note: Enabling the AP 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.
◆
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 — 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:
40-3500 TUs; Default: 100 TUs)
◆
Data Beacon Rate (DTIM) — 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 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 — 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 1, the access point always sends RTS signals. If set
to 2346, the access point never sends RTS signals. If set to any other value, and
– 62 –
Chapter 6 | Wireless Settings
Radio Settings
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: 1-2346
bytes: Default: 2346 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. (Default:
Enabled)
◆
Disable HT20/HT40 Coexistance — Prevents 802.11n 20 MHz and 40 MHz
channel bandwidths from operating together in the same network.
(Default: Disabled)
◆
Antenna Selection — Sets the radio to use one or both antennas. (Options:
Left, Right, Right+Left; Default: Right+Left)
◆
Minimum CCK Rate — (2.4 GHz radio only) The minimum CCK data rate at
which the AP transmits packets on the wireless interface. (Options: 1, 2, 5.5,
11 Mbps; Default 1 Mbps)
◆
Minimum OFDM Rate — The minimum OFDM data rate at which the AP
transmits packets on the wireless interface. (Range: 6, 9, 12, 18, 24, 36, 48,
54 Mbps; Default 6 Mbps)
◆
Minimum Single Stream Rate — The minimum 802.11n single stream data
rate at which the AP transmits packets on the wireless interface. (Range: MCS0MCS7; Default MCS0)
◆
Minimum Double Stream Rate — The minimum 802.11n double stream data
rate at which the AP transmits packets on the wireless interface. (Range: MCS8MCS15; Default MCS8)

Virtual Access Points (VAPs)
The AP supports up to 16 virtual access point (VAP) interfaces per radio, numbered
0 to 15. 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 VAP interfaces.
The VAPs function similar to a VLAN, with each VAP mapped to its own default
VLAN ID. Traffic to specific VAPs can be segregated based on user groups or
application traffic. All VAPs can support up to a total of 127 wireless clients,
whereby the clients associate with each VAP the same way as they would with
separate physical access points.
Note: The radio channel settings for the access point are limited by local
regulations, which determine the number of channels that are available. See
“Operating Channels” on page 46 for additional information on the maximum
number channels available.

Virtual Access Points (VAPs)
VAP Basic Settings Sets the basic operating mode and other settings for the VAP.
Each VAP can operate in one of three modes; normal AP mode, WDS-AP bridge AP
mode, or WDS-STA bridge station mode. The default mode is AP for the VAP to
support normal access point services.
Note: For more information and examples for setting up WDS networks, see “WDS
Setup Examples” on page 45.
Note that the Basic Settings are the same for both AP and WDS-AP modes.
Figure 30: VAP Basic Settings
The following items are displayed on this page:
◆
Closed System — When enabled, the VAP does not include its SSID in beacon
messages. Nor does it respond to probe requests from clients that do not
include a fixed SSID. (Default: Disable)
◆
Mode — Selects the mode in which the VAP will function.
◆
■
AP Mode: The VAP provides services to clients as a normal access point.
■
WDS-AP Mode: The VAP operates as an access point in WDS mode, which
accepts connections from APs in WDS-STA mode.
■
WDS-STA Mode: The VAP operates as a client station in WDS mode, which
connects to an access point VAP in WDS-AP mode. The user needs to
specify the MAC address of the access point in WDS-AP mode to which it
intends to connect.
Maximum Association Clients — The total maximum number of clients that
may associate with this VAP. The maximum is 127, which is the total associated
clients for all VAP interfaces. (Range: 1 to 127; Default 16)
– 66 –
Chapter 6 | Wireless Settings
Virtual Access Points (VAPs)
◆
WLAN Client Association Preemption — When enabled, the AP applies a
priority order for associating clients when the maximum clients for the VAP has
been reached. The priority order is 11n clients, 11a/g clients, then 11b clients.
When the association pool for the VAP is full and the AP receives an association
request from a high-priority (11n) client, the AP sends a disassociation to a
lower priority client (11a/g or 11b) in order to be able to associate the highpriority client. If there are no lower-priority clients to disassociate, the AP will
reject the association request. (Default: Disabled)
◆
Association Timeout Interval — The idle time interval (when no frames are
sent) after which a client is disassociated from the VAP interface. (Range: 5-60
minutes; Default: 30 minutes)
◆
Authentication Timeout Interval — The time within which the client should
finish authentication before authentication times out.
(Range: 5-60 minutes; Default: 60 minutes)
◆
Default VLAN ID — The VLAN ID assigned to wireless clients associated to the
VAP interface that are not assigned to a specific VLAN by RADIUS server
configuration. (Default: 1)
◆
DHCP Relay Server — The IP address of the DHCP relay server. 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 the access point, which then broadcasts them
back to clients. (Default: 0.0.0.0 (disabled))
◆
SSID — The service set identifier for the VAP.
◆
Multicast Enhancement — When a wireless client joins a multicast group, this
feature converts multicast packets to unicast packets to improve multicast
video quality.

◆
■
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: 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.

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 WEP provides a basic level of security, preventing unauthorized access to the
Privacy (WEP) network, and encrypting data transmitted between wireless clients and the VAP.
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)
and WPA2 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.
All clients share the same keys, which are used for user authentication and data
encryption. Up to four keys can be specified.

MAC Authentication Wireless clients can be authenticated for network access by checking their MAC
and RADIUS 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.
Remote Authentication Dial-in User Service (RADIUS) is an authentication protocol
that uses software running on a central server to control access to RADIUS-aware
devices on the network. An authentication server contains a database of user
credentials for each user that requires access to the network.
Local MAC Authentication
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)
The local MAC database provides a mechanism to take certain actions based on a
wireless client’s MAC address. The MAC list can be configured to allow or deny
network access to specific clients.

disabled; Range: 30-65535 seconds)
Primary and Secondary RADIUS Server Setup
A primary RADIUS server must be specified for the access point to implement IEEE
802.1X network access control and Wi-Fi Protected Access (WPA) wireless security.
A secondary RADIUS server may also be specified as a backup should the primary
server fail or become inaccessible.
In addition, you can configure a RADIUS Accounting server to 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 support
the access point. Configuration of RADIUS server software is beyond the scope of

A “rogue AP” is either an access point that is not authorized to participate in the
wireless network, or an access point that does not have the correct security
configuration. Rogue APs can allow unauthorized access to the network, or fool
client stations into mistakenly associating with them and thereby blocking access
to network resources.
The access point can be configured to periodically scan all radio channels and find
other access points within range. A database of nearby access points is maintained
where any rogue APs can be identified. Rogue access points can be identified by
unknown BSSID (MAC address).

Note: While the access point scans a channel for rogue APs, wireless clients will not
be able to connect to the access point. Therefore, avoid frequent scanning or scans
of a long duration unless there is a reason to believe that more intensive scanning is
required to find a rogue AP.
Wi-Fi Multimedia (WMM)
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 IEEE 802.11e QoS standard
and it enables the access point to interoperate 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 81). 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.

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.

SNMP Settings
This chapter describes Simple Network Management Protocol (SNMP) settings on
the access point.
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.
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
communicate with the access point, the management station must first submit a
valid community string for authentication.
Access to the access point using SNMP v3 provides additional security features that
cover message integrity, authentication, and encryption; as well as controlling
notifications that are sent to specified user targets.

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.

UDP port. A user-defined filter can also be assigned to specific targets to limit the
notifications received to specific MIB objects. (Note that the filter must first be
configured. See “SNMPv3 Notification Filters” on page 92.)
To configure a new notification receiver target, define the parameters and select a
filter, if required. Note that the SNMP v3 user name must first be defined (See
“SNMPv3 Users” on page 90.)
Figure 47: SNMPv3 Targets
The following items are displayed on this page:
◆
Target ID — A user-defined name that identifies a receiver of notifications.
(Maximum length: 32 characters)
◆
IP Address — Specifies the IP address of the receiving management station.
◆
UDP Port — The UDP port that is used on the receiving management station
for notification messages.
◆
SNMP User — The defined SNMP v3 user that is to receive notification
messages.
◆

SNMPv3 Notification Filters
SNMPv3 Notification Filters
SNMP v3 users can be configured to receive notification messages from the access
point. An SNMP Target ID is created that specifies the SNMP v3 user, IP address, and
UDP port. A user-defined notification filter can be created so that specific
notifications can be prevented from being sent to particular targets.
Figure 48: SNMP Notification Filter
The following items are displayed on this page:
◆
Filter ID — A user-defined name that identifies the filter. (Maximum length: 32
characters)
◆
Subtree — Specifies MIB subtree to be filtered. The MIB subtree must be
defined in the form “.1.3.6.1” and always start with a “.”.
◆
Type — Indicates if the filter is to “include” or “exclude” the MIB subtree objects
from the filter. Note that MIB objects included in the filter are not sent to the
receiving target and objects excluded are sent. By default all traps are sent, so
you can first use an “include” filter entry for all trap objects. Then use “exclude”
entries for the required trap objects to send to the target. Note that the filter
entries are applied in the sequence that they are defined.
◆
Action — Adds the notification filter.

Upgrading Firmware
You can upgrade new access point software from a local file on the management
workstation, or from an FTP or TFTP server. New software may be provided
periodically from your distributor.
After upgrading new software, you must reboot the access point to implement the
new code. Until a reboot occurs, the access point will continue to run the software
it was using before the upgrade started. Also note that new software that is
incompatible with the current configuration automatically restores the access
point to the factory default settings when first activated after a reboot.

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 AP through the console port, first set up a console connection to the
AP. See “Console Port Connection” on page 17 for more information.
At the console prompt, enter the user name and password. (The default user name
is “admin” with no default password.) After the password is entered, the CLI displays
the “EC#” prompt.
Example
(none) login: admin
Password:
Jan 1 11:33:13 login[1918]: root login on 'ttyS0'
EC#
Note: Command examples later in this chapter show the console prompt as “AP”.
Enter the necessary commands to complete your desired tasks.
When finished, exit the session with the “exit” command.
– 111 –
Chapter 10 | Using the Command Line Interface
Telnet Connection
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. If the access point does not acquire an IP
address from a DHCP server, the default IP address used by the access point for
management is 192.168.1.10.
To access the AP through a Telnet session, you must first set the IP address for the
AP, and set the default gateway if you are managing the AP 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)#
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 “AP#” prompt to show that you are using executive access mode (that is,
Exec).
(none) login: admin
Password:
AP#
3. Enter the necessary commands to complete your desired tasks.
4. When finished, exit the session with the “quit” or “exit” command.
Note: You can open up to four sessions to the device through Telnet.
– 112 –
Chapter 10 | Using the Command Line Interface
Entering Commands
Entering Commands
This section describes how to enter CLI commands.
Keywords and A CLI command is a series of keywords and arguments. Keywords identify a
Arguments 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:
AP(config)#password admin tpschris
Minimum The CLI will accept a minimum number of characters that uniquely identify a
Abbreviation command. For example, the command “configure” can be entered as con. If an
entry is ambiguous, the system will prompt for further input.
Command If you terminate input with a Tab key, the CLI will print the remaining characters of a
Completion 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 You can display a brief description of the help system by entering the help
Commands 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 ?

Negating the Effect of For many configuration commands you can enter the prefix keyword “no” to cancel
Commands 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 The CLI maintains a history of commands that have been entered. You can scroll
History 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.
Understanding The command set is divided into Exec and Configuration classes. Exec commands
Command Modes 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

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 “AP#” for Exec mode.
(none) login: 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 system name 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 beacon-interval.
◆
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 encryption.
To enter the Global Configuration mode, enter the command configure in Exec
mode. The system prompt will change to “AP(config)#” which gives you access
privilege to all Global Configuration commands.
– 115 –
Chapter 10 | Using the Command Line Interface
Entering Commands
AP#configure
AP(config)#
To enter Interface mode, you must enter the “interface ethernet” while in Global
Configuration mode. The system prompt will change to “AP(if-ethernet)#,” or
“AP(if-wireless 0)” indicating that you have access privileges to the associated
commands. You can use the exit command to return to the Exec mode.
AP(config)#interface ethernet
AP(if-ethernet)#
Command Line Commands are not case sensitive. You can abbreviate commands and parameters
Processing 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.

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 the access point, which then broadcasts them back to clients.

no snmp-server vacm view  [included | excluded] 
name - A user-defined name that identifies an SNMP v3 view. (Maximum
length: 32 characters)
– 159 –
Chapter 16 | SNMP Commands
include - Defines a filter type that includes objects in the MIB subtree.
exclude - Defines a filter type that excludes objects in the MIB subtree.
subtree - The part of the MIB subtree that is to be filtered.
mask - An optional hexadecimal value bit mask to define objects in the MIB
subtree.
Default Setting
None
Command Mode
Global Configuration
Command Usage
The access point allows multiple notification filters to be created. Each filter can
be defined by up to 20 MIB subtree ID entries.
◆
◆
Use the command more than once with the same filter ID to build a filter that
includes or excludes multiple MIB objects. Note that the filter entries are
applied in the sequence that they are defined.
◆
The MIB subtree must be defined in the form “.1.3.6.1” and always start with a “.”.
◆
The mask is 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.
Example
AP(config)#snmp-server vacm view testview include .1
AP(config)#snmp-server vacm view testview exclude .1.3.6.1.2.1.2.2.1.1.23

Command Usage
◆ The access point supports two software image files (A and B), one of which is
set as the boot image, or “Active” file, and the other acts as a “Backup” file.
◆
You can upgrade new access point software from a local file on the
management workstation, or from an FTP or TFTP server. The new software file
replaces the image (A or B) that is not currently set as the boot image.
◆
After upgrading new software, you must reboot the access point to implement
the new code. Until a reboot occurs, the access point will continue to run the
software it was using before the upgrade started. Also note that new software
that is incompatible with the current configuration automatically restores the
access point to the factory default settings when first activated after a reboot.

RADIUS Client Commands
Remote Authentication Dial-in User Service (RADIUS) is a logon authentication
protocol that uses software running on a central server to control access for
RADIUS-aware devices to the network. An authentication server contains a
database of credentials, such as users names and passwords, for each wireless
client that requires access to a VAP interface.

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.

The minimum value is the higher of 4 or [(max-age / 2) + 1].
Default Setting
15 seconds
Command Mode
Global Configuration
Command Usage
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.
Example
AP(config)#bridge stp br-conf forwarding-delay 20

Global Configuration
Command Usage
This command sets 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

Default Setting
Automatic channel selection
Command Mode
Interface Configuration (Wireless)
Command Usage
◆ The available channel settings are limited by local regulations, which
determine the number of channels that are available.
◆
The available channels depend on the radio interface, either 11b/g/n (2.4 GHZ)
or 11a/n (5 GHz).
◆
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 increases connection speed for
802.11n up to 300 Mbps.
◆
HT40plus indicates that the secondary channel is above the primary channel.
HT40minus indicates that the secondary channel is below the primary channel.
◆
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.

Command Usage
◆ 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.

Disabled
Command Mode
Interface Configuration (Wireless)
Command Usage
The 802.11n draft specifies two guard intervals: 400ns (short) and 800ns (long).
Support of the 400ns guard interval 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.

If want to take effect, please execute make-RF-setting-effective command !
AP(if-wireless 0)#
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 between the beacon frames that transmit broadcast or
multicast traffic. (Range: 1-255 beacon frames)
Default Setting
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 1 indicates that the access point will
save all broadcast/multicast frames for the Basic Service Set (BSS) and forward
them after every beacon.
◆
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
– 219 –
Chapter 25 | Wireless Interface Commands
stations in Power Save mode, but delays the transmission of broadcast/
multicast frames.

AP(if-wireless 0)#
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 packet size for which to send an RTS.
(Range: 1-2346 bytes)
Default Setting
2346
Command Mode
Interface Configuration (Wireless)
Command Usage
◆ If the threshold is set to 1, the access point always sends RTS signals. If set to
2346, 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.

Command Usage
When enabled, the AP applies a priority order for associating clients when the
maximum clients for the VAP has been reached. The priority order is 11n clients,
11a/g clients, then 11b clients.
◆
◆
When the association pool for the VAP is full and the AP receives an association
request from a high-priority (11n) client, the AP sends a disassociation to a
lower priority client (11a/g or 11b) in order to be able to associate the highpriority client. If there are no lower-priority clients to disassociate, the AP will
reject the association request.

When you have long-distance links in the wireless network, some timing
parameters require an adjustment to maintain communications. You can enable
this feature and then use the long-distance reference-data command to suggest
settings based on an approximate distance.

auth This command configures authentication for the VAP interface.
Syntax
auth 
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 WEP 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.
– 239 –
Chapter 26 | Wireless Security Commands
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
Default Setting
open-system
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 opensystem disables encryption and 802.1X.
◆
To use WEP shared-key authentication, set the authentication type to “sharedkey” 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 177) and RADIUS server details (see “RADIUS Client
Commands” on page 171) 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, WPAWPA2-mixed, or WPA-WPA2-PSK-mixed), the 802.1X settings (see “802.1X
Authentication Commands” on page 177) and RADIUS server details (see
“RADIUS Client Commands” on page 171) 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 WPAWPA2-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 242 and “transmit-key” on page 243).
– 240 –
Chapter 26 | Wireless Security Commands
◆
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.

Command Mode
Interface Configuration (Wireless-VAP)
Command Usage
Selecting a security method using the auth command, automatically enables
data encryption (WEP, TKIP, or AES-CCMP) for the VAP. Only use this command
when using WEP encryption with an Open System.
◆
◆
Encryption is implemented in this device to prevent unauthorized access to
your wireless network. For more secure data transmissions, enable encryption
by selecting a security method using the auth command, or by using the
encryption command when using WEP encryption only.
◆
The encryption settings must be the same on each client in your wireless
network.
◆
Note that encryption protects data transmitted between wireless nodes, but
does not protect any transmissions over your wired network or over the
Internet.

Command Usage
◆ 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 dynamic keys with 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.

cipher-suite This command defines the cipher algorithm used to encrypt the global key for
broadcast and multicast traffic when using WPA or WPA2 security.
Syntax
multicast-cipher 
aes-ccmp - Use AES-CCMP encryption for the unicast and multicast cipher.
tkip - Use TKIP encryption for the multicast cipher. TKIP or AES-CCMP can
be used for the unicast cipher depending on the capability of the client.
Default Setting
None
Command Mode
Interface Configuration (Wireless-VAP)
Command Usage
◆ WPA and WPA2 enable a VAP 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 WPA2compliant 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.

Rogue AP Detection Commands
A “rogue AP” is either an access point that is not authorized to participate in the
wireless network, or an access point that does not have the correct security
configuration. Rogue APs can potentially allow unauthorized users access to the
network. Alternatively, client stations may mistakenly associate to a rogue AP and
be prevented from accessing network resources. Rogue APs may also cause radio
interference and degrade the wireless LAN performance.
The access point can be configured to periodically scan all radio channels and find
other access points within range. A database of access points is maintained so that
any rogue APs can be identified.

Command Usage
◆ While the access point scans a channel for rogue APs, wireless clients will not be
able to connect to the access point. Therefore, avoid frequent scanning or scans
of a long duration unless there is a reason to believe that more intensive
scanning is required to find a rogue AP.
◆
A “rogue AP” is either an access point that is not authorized to participate in the
wireless network, or an access point that does not have the correct security
configuration. Rogue access points can be identified by unknown BSSID (MAC
address). A database of nearby access points should therefore be maintained
on the AP, allowing any rogue APs to be identified (see rogue-ap add friendly).
The rogue AP database can be viewed using the show rogue-ap command.

Link Integrity Commands
The access point provides a link integrity feature that can be used to ensure that
wireless clients are connected to resources on the wired network. The access point
does this by periodically sending Ping messages to a host device in the wired
Ethernet network. If the access point detects that the connection to the host has
failed, it disables the radio interfaces, forcing clients to find and associate with
another access point. When the connection to the host is restored, the access point
re-enables the radio interfaces.

Command Usage
◆ When link integrity is enabled, the IP address of a host device in the wired
network must be specified.
◆
The access point periodically sends an ICMP echo request (Ping) packet to the
link host IP address. When the number of failed responses (either the host does
not respond or is unreachable) exceeds the limit set by this command, the link
is determined as lost. The link-integrity link-fail-action command can be used to
disable radio interfaces when the host link is lost.
◆
The AP continues to send Ping messages to determine if the link to the host is
restored. When the connection to the host is restored, the access point reenables the radio interfaces if they have been shut down.
Example
AP(config)#link-integrity 10.20.30.40 interval 500 timeout 5 retry 3

Link Layer Discovery Commands
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.

VLAN Commands
The access point can enable the support of VLAN-tagged traffic passing between
wireless clients and the wired network. VLAN IDs can be mapped to specific VAP
interfaces, allowing users to remain within the same VLAN as they move around a
campus site.
Caution: 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.

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 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.

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. 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.

◆
Be sure the AP is powered up.
Check network cabling between the management station and the
AP.
Check that you have a valid network connection to the AP and
that intermediate switch ports have not been disabled.
Be sure you have configured the AP with a valid IP address, subnet
mask and default gateway.
Be sure the management station has an IP address in the same
subnet as the AP’s IP.
If you are trying to connect to the AP using a tagged VLAN group,
your management station, and the ports connecting intermediate
switches in the network, must be configured with the appropriate
tag.
If you cannot connect using Telnet, you may have exceeded the
maximum number of concurrent Telnet/SSH sessions permitted.
Try connecting again at a later time.
Be sure you have set the terminal emulator program to VT100
compatible, 8 data bits, 1 stop bit, no parity, and the baud rate set
to 115200 bps.
Check that the null-modem serial cable conforms to the pin-out
connections provided in the Installation Guide.
Reset the AP to factory defaults using its Reset button.
Using System Logs
If a fault does occur, refer to the Installation Guide to ensure that the problem you
encountered is actually caused by the AP. If the problem appears to be caused by
the AP, follow these steps:
1. Enable logging.
2. Set the error messages reported to include all categories.
3. Enable SNMP.
4. Enable SNMP traps.

Appendix A | Troubleshooting
Using System Logs
5. Designate the SNMP host that is to receive the error messages.
6. Repeat the sequence of commands or other actions that lead up to the error.
7. Make a list of the commands or circumstances that led to the fault. Also make a
list of any error messages displayed.
8. Set up your terminal emulation software so that it can capture all console
output to a file. Then enter the “show config” command to record all system
settings in this file.
9. Contact your distributor’s service engineer, and send a detailed description of
the problem, along with the file used to record your system settings.
For example:
AP(config)#logging on
AP(config)#logging host 1 10.1.0.3
AP(config)#logging level alert
AP(config)#snmp-server host 1 10.1.0.23 batman
