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.
