Introduction
Cisco Aironet Access Points are wireless LAN transceivers that can act as the connection point between
wireless and wired networks or as the center point of a standalone wireless network. Cisco Aironet
Bridges are wireless LAN transceivers that connect two or more remote networks into a single LAN.

New Features
Firmware version 11.23T includes these new software features:
•
Configurable radius message transmission interval
•
Displayable active authentication servers
•
Configurable time interval for automatic reattempt to return to the primary server
The radius retransmission interval and primary server reattempt interval features are configurable using
the web, console, or SNMP interfaces.

Radius Message Transmission Interval
The Request Radius Retransmission interval is now configurable for both authentication and accounting
servers. The default value is 5 seconds. The total number of maximum transmissions is also configurable
and has a default value of 3. Using this value, if nothing is heard from the server within 5 seconds, a
second retransmission request is transmitted. After three retransmission requests with no reply, the
server is assumed to be down.

and has a default value of 3. Using this value, if nothing is heard from the server within 5 seconds, a
second retransmission request is transmitted. After three retransmission requests with no reply, the
server is assumed to be down.
If the access point and the AAA server are connected through a low-speed network and the Radius
Message Retransmission Interval is set too low, the network may become congested because the access
point retransmits unacknowledged requests that have not yet reached the server.

Display of Active Authentication Servers
By viewing the authentication server screens, an administrator can determine the most recently used
authentication server for the following authentication functions:
authentication server for the following authentication functions:
•
EAP (802.1X) authentication such as LEAP, EAP-TLS, and EAP-MD5
•
MAC address authentication
For each authentication function, the access point configuration specifies one or more authentication
servers, with the first one designated the primary or default server. The remaining servers act as backup
servers. By default, the primary server is the currently selected server for the respective categories.

An administrator can view any server currently selected for a particular function. The currently selected
server for each of these functions is displayed in green text so that the administrator can easily determine
the active server in each category. On the console or Telnet interface, the active server is identified
numerically.
