DXS-3350SR Gigabit Layer 3 Switch 

Authentication Server Group Settings 

This window will allow users to set up Authentication Server Groups on the Switch. A server group is a technique used to 

group TACACS/XTACACS/TACACS+/RADIUS server hosts into user-defined categories for authentication using method 

lists. The user may define the type of server group by protocol or by previously defined server group. The Switch has three 

built-in Authentication Server Groups that cannot be removed but can be modified. Up to eight (8) authentication server 

hosts may be added to any particular group. 

To view the following window, click Security Management > Access Authentication Control > Authentication Server 

Group: 

Figure 7- 7. Authentication Server Group Settings window 

This screen displays the Authentication Server Groups on the Switch. The Switch has three built-in Authentication Server 

Groups that cannot be removed but can be modified. To modify a particular group, click its hyperlinked Group Name, 

which will then display the following window. 

Figure 7- 8. Add a Server Host to Server Group (tacacs) 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. 

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.
