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
DellEMC(conf)#radius-server group group1
DellEMC(conf-radius-group)#radius-server vrf vrf1 source-interface
tengigabitethernet 1/40
DellEMC(conf)#radius-server group group2
DellEMC(conf-radius-group)#radius-server vrf default
