send authentication packets to a remote TACACS / XTACACS / TACACS+ / RADIUS server host on a remote host.
The TACACS / XTACACS / TACACS+ / RADIUS server host will then verify or deny the request and return the
appropriate message to the Switch. More than one authentication protocol can be run on the same physical server host
but, remember that TACACS / XTACACS / TACACS+ / RADIUS are separate entities and are not compatible with
each other. The maximum supported number of server hosts is 16.
