Figure 8-54 Authentication Server Group Settings – Edit Server Group window
To add an Authentication Server Host to the list, enter its name in the Group Name field, IP address in the IP
Address field, use the drop-down menu to choose the Protocol associated with the IP address of the
Authentication Server Host, and then click Add to add this Authentication Server Host to the group. The entry
should appear in the Host List at the bottom of this tab.
NOTE: The user must configure Authentication Server Hosts using the Authentication Server Settings
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.
