TACACS+ authentication enables you to use a central server to allow or deny
access to the Series 5300XL switches (and other TACACS-aware devices) in
your network. This means that you can use a central database to create
multiple unique username/password sets with associated privilege levels for
use by individuals who have reason to access the switch from either the
switch's console port (local access) or Telnet (remote access).
