• 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.
The RADIUS Accounting features supported by this access point are standard and non‐vendor
specific. For a full understanding of RADIUS Accounting attributes supported, refer to RFC 2865.

RADIUS Accounting enables or disables the AP to send RADIUS accounting information
for clients to the RADIUS accounting server. Default: Disable
Accounting Port specifies the specific destination port for RADIUS accounting packets. A
value between 1024 and 65535. This value must match the configuration of your primary
RADIUS accounting server. Default: 1813
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).
