I just added a AAA tacacs server group to a switch. I made sure to take turns disabling tacacs on both servers one at a time so that I could see that each server was responding as respected to tacacs requests from the switch.
I have noticed since going from a single tacacs server to a group there is a delay in privileged exec mode. As soon as I go into global config mode, commands from there seem to be fine. Just to type conf t to though in priv exec mode is really slow.
Anyone encounter this?
