The following is a list of the Dell Networking OS version history for this command.
Version Description
9.7(0.0) Introduced on the S6000–ON.
9.4.(0.0) Introduced on the S-Series and Z-Series.
Usage
Information You can use this command to associate a group of TACACS 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 TACACS group, then the group is considered to be
on the 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.
