Setting the RADIUS Dead Time

You can configure the switch so that when a RADIUS server does not respond to an authentication
request, the switch marks that server as dead for the length of time specified by the dead time. Any
authentication requests received during the dead time interval (such as other users attempting to log in
to the switch) are not sent to a RADIUS server marked dead. Configuring a dead time speeds up the
authentication process, by eliminating timeouts and retransmissions to the dead RADIUS server.
If you configure only one RADIUS server, or if all of the configured servers are marked dead, the dead
time is ignored because there are no alternate servers available.
To set the RADIUS dead time, perform this task in privileged mode:
Task
Step 1
Configure the RADIUS server dead time interval. set radius deadtime minutes
Step 2 Verify the RADIUS configuration.
This example shows how to set the RADIUS deadtime interval and verify the configuration:
Console> (enable) set radius deadtime 5
Radius deadtime set to 5 minute(s).
Console> (enable) show radius
