Chapter 30 Configuring Switch Access Using AAA
Setting the RADIUS Retransmit Count
You can set the number of times the switch will attempt to contact a RADIUS server before the next
configured server is tried. By default, each RADIUS server will be tried two times.
To set the RADIUS retransmit count, perform this task in privileged mode:
Task
Step 1
Set the RADIUS server retransmit count.
Step 2 Verify the RADIUS configuration.
This example shows how to set the RADIUS retransmit count as 4 and how to verify the configuration:
Console> (enable) set radius retransmit 4
Radius retransmit count set to 4.

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 that is specified in the set radius
deadtime command. Any authentication requests that are received during the dead time interval (such
as other users attempting to log in to the switch) are not sent to a RADIUS server that is 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.
