Interim Update Timeout determines how often to send accounting updates from the access
point to the server for this session. This value can be overridden by the RADIUS server.
Default: 3600 seconds (one hour), Range: 60 seconds (one minute) to 86400 seconds (one day).
Secondary Radius Server Setup is used to configure a second 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.
Using the CLI
From the global configuration mode, use the radius‐server address command to specify the
address of the primary RADIUS server, or the radius‐server secondary address command to
specify the address of the secondary RADIUS server. (The following example configures settings
for the primary RADIUS server.) Use the radius‐server or radius server secondary and key, port,
port‐accounting, retransmit, timeout, and timeout‐iterim commands to configure the other
RADIUS server parameters. Use the show radius command from the Exec mode to display the
current settings for the primary and secondary RADIUS servers.
