Authentication Server Settings - D-Link xStack Reference Manual

xStack® DGS-3120 Series Layer 2 Stackable Managed Switch Web UI Reference Guide
Figure 8-60 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 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.
