Primary Radius Server Setup – Configure the following settings to use RADIUS
authentication on the access point.
• IP Address: Specifies the IP address or host name of the RADIUS server.
• Port: The UDP port number used by the RADIUS server for authentication
messages. (Range: 1024-65535; Default: 1812)
• Key: A shared text string used to encrypt messages between the access point and
the RADIUS server. Be sure that the same text string is specified on the RADIUS
server. Do not use blank spaces in the string. (Maximum length: 255 characters)
• Timeout: Number of seconds the access point waits for a reply from the RADIUS
server before resending a request. (Range: 1-60 seconds; Default: 5)
• Retransmit attempts: The number of times the access point tries to resend a
request to the RADIUS server before authentication fails. (Range: 1-30; Default: 3)
• Interim Update Timeout: The interval between transmitting accounting updates to
the RADIUS server. (Range: 60-86400; Default: 3600 seconds)
Note: For the Timeout and Retransmit attempts fields, accept the default values unless
you experience problems connecting to the RADIUS server over the network.
Secondary Radius Server Setup – Configure a secondary RADIUS server to provide
a backup in case the primary server fails. The access point uses the secondary
server if the primary server fails or becomes inaccessible. Once the access point
switches over to the secondary server, it periodically attempts to establish
communication again with primary server. If communication with the primary server
is re-established, the secondary server reverts to a backup role.
