This window displays the Authentication Server Groups on the Switch. The Switch has four built-in Authentication Server Groups
that cannot be removed but can be modified. To add a new Server Group, enter a name in the Group Name field and then click the
Add button. To modify a particular group, click the Edit button (or the Edit Server Group tab), which will then display the
following Edit Server Group tab:
Figure 6 - 48. Edit Server Group tab of the Authentication 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.
To add a server group other than the ones listed, enter a name of up to 15 characters in the Group Name field, an IP address in the
IP Address field, use the drop-down menu to choose the Protocol associated with the IP address, and then click Apply. The entry
should appear in the Server Group List 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.
