authentication.
If you configure a global encryption key, the switch uses it only with servers
for which you have not also configured a server-specific key. Thus, a global
key is more useful where the TACACS+ servers you are using all have an
identical key, and server-specific keys are necessary where different
TACACS+ servers have different keys.
If TACACS+ server "X" does not have an encryption key assigned for the
switch, then configuring either a global encryption key or a server-specific key
in the switch for server "X" will block authentication support from server "X".
