NOTE:
The three built-in server groups can only have server hosts running the same TACACS
daemon. TACACS/XTACACS/ protocols are separate entities and are not
compatible with each other.
Authentication Server Settings
User-defined Authentication Server Hosts for the TACACS / XTACACS / / RADIUS security protocols
can be set on the Switch. When a user attempts to access the Switch with Authentication Policy enabled, the
Switch will send authentication packets to a remote TACACS / XTACACS / / RADIUS server host on a
remote host. The TACACS / XTACACS / / 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 / / RADIUS are separate entities and are
not compatible with each other. The maximum supported number of server hosts is 16.
