is selected) from the list.
• Server IP Address/Name—Enter the IP address or name of the TACACS+ server.

you do not have an encrypted key string (from another device), enter the key string in
plaintext mode and click Apply. The encrypted key string is generated and displayed.
If you enter a key, this overrides the default key string if one has been defined for the
device on the main page.
