In the toolbar located above the topology map, open the Device statuses drop-down list.
You will see a list containing the names of statuses for known devices (Unauthorized, Authorized, Archived), and the Unmanaged switch status for unmanaged switches.
In the drop-down list, select the check boxes for the statuses of devices that need to be displayed on the topology map.
Click OK.
The topology map will display only those nodes that have the selected statuses.
By default, the topology map displays all nodes regardless of whether they have links to other nodes. If necessary, you can disable the display of all nodes that do not have links with other nodes on the topology map.
To enable or disable the display of nodes that do not have links to other nodes:
Use the Display unlinked nodes toggle button in the toolbar located above the topology map.
