Optional, global "encryption key"


key <key-string>

Specifies the optional, global "encryption key" that is also assigned in the TACACS+ servers that the switch will access for authentication. This option is subordinate to any "per-server" encryption keys you assign, and applies only to accessing TACACS+ servers for which you have not given the switch a "per-server" key. (See the host <ip-addr> [key <key-string>] entry above.)

You can configure a TACACS+ encryption key that includes a tilde (~) as part of the key, for example, "hp~switch".

For more on the encryption key, see Using the encryption key and the documentation provided with your TACACS+ server application.

Configuring a host-specific key
