xStack® DGS-3600 Series Layer 3 Managed Gigabit Ethernet Switch To add an Authentication Server Host to the list, enter its IP address in the IP Address field, choose the protocol associated with the IP address of the Authentication Server Host and click Add to Group to add this Authentication Server Host to the group.

Authentication Server Group Table Add Settings window Simply enter a group name of no more than 15 alphanumeric characters to define the user group to add. After clicking Apply, the new user-defined group will be displayed in the Authentication Server Group window. Here, it can be configured as the user desires. 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 four 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. To view this window, click Security > Access Authentication Control > Authentication Server Host, as shown below: Figure 7- 49.
