Specifying a RADIUS Server Host

When configuring a RADIUS server host, you can set different communication parameters, such as the UDP port, the key password, the number of retries, and the timeout.

To specify a RADIUS server host and configure its communication parameters, use the following command.
Enter the host name or IP address of the RADIUS server host.
CONFIGURATION mode
radius-server host {hostname | ip-address} [auth-port port-number] [retransmit retries] [timeout seconds] [key [encryption-type] key]
Configure the optional communication parameters for the specific host:
  • auth-port port-number: the range is from 0 to 65535. Enter a UDP port number. The default is 1812.
  • retransmit retries: the range is from 0 to 100. Default is 3.
  • timeout seconds: the range is from 0 to 1000. Default is 5 seconds.
  • key [encryption-type] key: enter 0 for plain text or 7 for encrypted text, and a string for the key. The key can be up to 42 characters long. This key must match the key configured on the RADIUS server host.
If you do not configure these optional parameters, the global default values for all RADIUS host are applied.
To specify multiple RADIUS server hosts, configure the radius-server host command multiple times. If you configure multiple RADIUS server hosts, Dell EMC Networking OS attempts to connect with them in the order in which they were configured. When Dell EMC Networking OS attempts to authenticate a user, the software connects with the RADIUS server hosts one at a time, until a RADIUS server host responds with an accept or reject response.

If you want to change an optional parameter setting for a specific host, use the radius-server host command. To change the global communication settings to all RADIUS server hosts, refer to Setting Global Communication Parameters for all RADIUS Server Hosts.

To view the RADIUS configuration, use the show running-config radius command in EXEC Privilege mode.

To delete a RADIUS server host, use the no radius-server host {hostname | ip-address} command.
