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 Settings

User-defined Authentication Server Hosts for the TACACS / XTACACS / TACACS+ / 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 / 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.

Enter a number between 1 and 65535 to define the virtual port number of the
authentication protocol on a server host. The default port number is 49 for
TACACS/XTACACS/TACACS+ servers and 1812 for RADIUS servers but the user
may set a unique port number for higher security.
Enter the time in seconds the Switch will wait for the server host to reply to an
