TACACS+ Client
Terminal Access Controller Access Control System (TACACS+) is a logon
authentication protocol that uses software running on a central server to control
access to TACACS-aware devices on the network. An authentication server contains
a database of multiple user name/password pairs with associated privilege levels
for each user or group that require management access to a switch.

the no form to remove the server, or to restore the default values.
