D-Link DES-3028 User Manual - Authentication Server Host

DES-3028 DES-3028P DES-3052 DES-3052P Layer 2 Fast Ethernet Managed Switch 

Figure 10- 31. Add a Server Host to Server Group (radius) window 

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. 

To add a user-defined group to the list, click the Add button in the Authentication Server Group window, which will display the 

following window. 

Figure 10- 32. Authentication Server Group Table Add Settings 

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.
