When a user attempts to log into the switch, the NAS or switch prompts for a username and password. The switch attempts to communicate with the highest priority configured TACACS+ server at

10.10.10.10.Upon successful connection with the server, the switch and server exchange the login credentials over an encrypted channel. The server then grants or denies access, which the switch honors, and either allows or does not allow the user to gain access to the switch. If neither of the two servers can be contacted, the switch searches its local user database for the user.
