Users Guide

If a VRF is not congured on the TACACS group, then servers congured in the group are considered to be
on the default VRF. TACACS servers that are congured in the CONFIGURATION mode are also considered
to be on the default VRF.
For AAA servers to use a group of TACACS servers, you must explicitly congure the group using the aaa
tacacs group group-name command. The order in which the TACACS servers are tried depends on
the order in which they are congured.
Example
Dell(conf)# tacacs-server group group1
Dell(conf-tacacs-group)# tacacs-server host 1.1.1.1 key secr-et
Dell(conf-tacacs-group)# no tacacs-server host 1.1.1.1
Dell(conf-tacacs-group)#
