NOTE: The user must configure Authentication Server Hosts using the Authentication Server
Hosts window before adding hosts to the list. Authentication Server Hosts must be configured for
their specific protocol on a remote centralized server before this function can work properly.
NOTE: The three built in server groups can only have server hosts running the same TACACS
daemon. TACACS/XTACACS/TACACS+ protocols are separate entities and are not compatible
with each other.

Authentication Server Host

This window will set user-defined Authentication Server Hosts for the TACACS / XTACACS / TACACS+ / RADIUS security
protocols 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 / 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.
