DWS-3000 with TACACS+
When a user attempts to log into the switch, the NAS or switch prompts for a user name 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.
Configuring TACACS+ by Using CLI Commands
