9.4(0.0) Introduced on the S-Series and Z9000.
Usage
Information You can use this command to associate a group of RADIUS servers with a VRF and
source interface. You can configure the source interface only with the VRF
attribute and source interface is optional with the VRF attributes.
If VRF is not configured on the RADIUS group, then the group is considered to be
on the default VRF. It is possible to use the default VRF name; however, you cannot
configure the source interface with the default VRF as such a configuration results
in conflicts between the source interfaces corresponding to the 802.1x supplicants
on that default VRF.
RADIUS groups and VRFs have one-to-one mapping. If a VRF is configured with
one RADIUS group, then you cannot use the same VRF with another RADIUS
group. When the VRF is removed, then the corresponding RADIUS group is also
removed automatically.
Example Dell(conf)#radius-server group group1
Dell(conf-radius-group)#radius-server vrf vrf1 source-
interface tengigabitethernet 1/40
Dell(conf)#radius-server group group2
Dell(conf-radius-group)#radius-server vrf default
Configure a key for all RADIUS communications between the switch and the RADIUS host server.
