Version pre-6.2.1.0 Description Introduced on the E-Series. Usage Information To configure any number of RADIUS server hosts for each server host that is configured, use this command. Dell Networking OS searches for the RADIUS hosts in the order they are configured in the software. The global default values for the timeout, retransmit, and key optional parameters are applied, unless those values are specified in the radius-server host or other commands. To return to the global default values, if you configure the timeout, retransmit, or key values, include those keywords when using the no radiusserver host command syntax. You can use duplicate host names or IP addresses among RADIUS groups. However, you cannot use duplicate host names or IP addresses within the same RADIUS group. If a VRF is not configured on the RADIUS group, then servers configured in the group are considered to be on the default VRF. RADIUS servers that are configured in the CONFIGURATION mode are also considered to be on the default VRF. You must configure the RADIUS group explicitly with the aaa radius group command in order for the AAA servers to use the group of RADIUS servers. The 802.1x servers use the group of RADIUS servers based on the VRF where the 802.1x request is received. As a result, it is possible that both globally configured RADIUS servers as well as the group-configured RADIUS servers (without VRF or default VRF) are used for processing the 802.1x requests that are received at the default VRF. The order in which the RADIUS servers are tried depends on the order in which the RADIUS servers are configured. Example Dell(config)#radius-server host 192.100.0.12 Force all logged-in users to re-authenticate (y/n)? Dell(config)#no radius-server host 192.100.0.12 Force all logged-in users to re-authenticate (y/n)? Related Commands • login authentication - sets the database to be checked when a user logs in. • radius-server key - sets an authentication key for RADIUS communications. • radius-server retransmit - sets the number of times the RADIUS server attempts to send information. • radius-server timeout - sets the time interval before the RADIUS server times out. radius-server vrf Create an association between a RADIUS server group and a VRF and source interface. ud Syntax radius-server vrf vrf-name [source-interface interface] To delete the association between a RADIUS server group and a VRF and source interface, use the no radiusserver vrf vrf-name [source-interface interface] command. Parameters vrf vrf-name interface Enter the keyword vrf and then the name of the VRF to associate a RADIUS server group with that VRF. Enter the following keywords and slot/port or number information: • For a 1-GigabitEthernet interface, enter the keyword GigabitEthernet then the slot/port information. Security 1471
