30.14 radius-server key
Command: radius-server key <string>
no radius-server key
Function: Specifies the key for the RADIUS server (authentication and accounting); the
―no radius-server key‖ command deletes the key for RADIUS server.
Parameters: <string> is a key string for RADIUS server, up to 16 characters are allowed.
Command mode: Global Mode
Usage Guide: The key is used in the encrypted communication between the switch and
the specified RADIUS server. The key set must be the same as the RADIUS server set,
otherwise, proper RADIUS authentication and accounting will not perform properly.
Example: Setting the RADIUS authentication key to be ―test‖.
Switch(config)#radius-server key test
30.15 radius-server retransmit
Command: radius-server retransmit <retries>
no radius-server retransmit
Function: Configures the re-transmission times for RADIUS authentication packets; the
―no radius-server retransmit‖ command restores the default setting.
Parameters: <retries> is a retransmission times for RADIUS server, the valid range is 0
to 100.
Command mode: Global Mode
Default: The default value is 3 times.
Usage Guide: This command specifies the retransmission time for a packet without a
RADIUS server response after the switch sends the packet to the RADIUS server. If
authentication information is missing from the authentication server, AAA authentication
request will need to be re-transmitted to the authentication server. If AAA request
retransmission count reaches the retransmission time threshold without the server
responding, the server will be considered to as not work, the switch sets the server as
invalid.
Example: Setting the RADIUS authentication packet retransmission time to five times.
Switch(config)#radius-server retransmit 5
30.16 radius-server timeout
Command: radius-server timeout <seconds>
