Communicating with a RADIUS Server
To enable communication between the RADIUS security (database) server and the access server,
enter the commands listed in Table 4-4.
You can use any of the following optional commands to interact with the RADIUS server host:
•
radius-server retransmit number
This command specifies the number of times that the access server transmits each RADIUS
request to the server before the access server gives up.
•
radius-server timeout seconds
This command specifies the number of seconds that the access server waits for a reply to a
RADIUS request before the access server retransmits the request. The default is 5 seconds. If the
RADIUS server’s response is slow (because of support for a large number of users or large
network latency), increase the timeout value.
For more information about these commands, refer to the Security Command Reference, available
online at
