Command Modes Global configuration
Command History
Usage Guidelines We recommend that you configure the seconds and number parameters as follows:
• Use the radius-server timeout seconds global configuration command to specify the time in
seconds during which the switch waits for a RADIUS server to respond before the IEEE 802.1x
authentication times out. The switch dynamically determines the default seconds value that is from
10 to 60 seconds.
• Use the radius-server retransmit retries global configuration command to specify the number of
times the switch tries to reach the radius servers before considering the servers to be unavailable.
The switch dynamically determines the default tries value that is from 10 to 100.
• The seconds parameter is less than or equal to the number of retransmission attempts times the time
in seconds before the IEEE 802.1x authentication times out.
• The tries parameter should be the same as the number of retransmission attempts.
Examples This example shows how to configure 60 as the time and 10 as the number of tries, the conditions that
determine when a RADIUS server is considered unavailable
Switch(config)# radius-server dead-criteria time 60 tries 10
You can verify your settings by entering the show running-config privileged EXEC command.
