Setting the Default RADIUS Server Timeout Interval and Retransmits
Procedure
Step 1
switch# configure terminal
Enters configuration mode.
Step 2 switch(config)# radius-server timeout 30
Configures the global timeout period in seconds for the switch to wait for a response from all RADIUS+
servers before the switch declares a timeout failure. The time ranges from 1 to 1440 seconds.
Step 3 switch(config)# no radius-server timeout 30
Reverts the transmission time to the default value (1 second).
Setting the Default RADIUS Server Timeout Interval and Retransmits
By default, a switch retries transmission to a RADIUS server only once before reverting to local authentication.
You can increase this number up to a maximum of five retries per server. You can also configure the timeout
value for the RADIUS server.
To specify the number of times that RADIUS servers should try to authenticate a user, follow these steps:
Procedure
Step 1
switch# configure terminal
Enters configuration mode.
Step 2 switch(config)# radius-server retransmit 3
Configures the number of times (3) the switch tries to connect to a RADIUS server(s) before reverting to local
authentication.
Step 3
switch(config)# no radius-server retransmit
Reverts to the default retry count (1).
Configuring RADIUS Server Monitoring Parameters
You can configure parameters for monitoring RADIUS servers. You can configure this option to test the
server periodically, or you can run a one-time only test.
This section includes the following topics:
Configuring the Test Idle Timer
The test idle timer specifies the interval during which a RADIUS server receives no requests before the MDS
switch sends out a test packet.
