• Network Device Groups—This table lists the name of each NDG that has
been configured, and the number of AAA clients and AAA servers assigned
to each NDG. If you are using NDGs, the AAA Clients table and AAA
Servers table do not appear on the opening page. To configure a AAA client
or AAA server, you must click the name of the NDG to which the device is
assigned. If the newly configured device is not assigned to an NDG, it
automatically belongs to the (Not Assigned) group.
This table appears only when you have configured the interface to use NDGs.
For more information about this interface configuration, see the “Advanced
Options” section on page 3-4.

This table appears only when you have configured the interface to enable
