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.

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.
