Setting Global Communication Parameters for all RADIUS Server Hosts
You can congure global communication parameters (auth-port, key, retransmit, and timeout parameters) and specic
host communication parameters on the same system.
However, if you congure both global and specic host parameters, the specic host parameters override the global parameters for
that RADIUS server host.
To set global communication parameters for all RADIUS server hosts, use the following commands.
• Set a time interval after which a RADIUS host server is declared dead.
CONFIGURATION mode
radius-server deadtime seconds
– seconds: the range is from 0 to 2147483647. The default is 0 seconds.
• Congure a key for all RADIUS communications between the system and RADIUS server hosts.
CONFIGURATION mode
radius-server key [encryption-type] key
– encryption-type: enter 7 to encrypt the password. Enter 0 to keep the password as plain text.
– key: enter a string. The key can be up to 42 characters long. You cannot use spaces in the key.
• Congure the number of times the system retransmits RADIUS requests.
CONFIGURATION mode
radius-server retransmit retries
– retries: the range is from 0 to 100. Default is 3 retries.
• Congure the time interval the system waits for a RADIUS server host response.
CONFIGURATION mode
radius-server timeout seconds
– seconds: the range is from 0 to 1000. Default is 5 seconds.
To view the conguration of RADIUS communication parameters, use the show running-config command in EXEC Privilege
mode.
Monitoring RADIUS
To view information on RADIUS transactions, use the following command.
• View RADIUS transactions to troubleshoot problems.
