Usage Information
You can use this command to associate a group of RADIUS servers with a VRF and source interface. You
can congure the source interface only with the VRF attribute and source interface is optional with the VRF
attributes.
If VRF is not congured 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 congure the source interface with the default
VRF as such a conguration results in conicts 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 congured 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 1/30/1
Dell(conf)#radius-server group group2
Dell(conf-radius-group)#radius-server vrf default
