Some devices does not support the network neighbour discovery protocols ( e.g. Firewalls), or you might not have the discovery protocol enabled. This section allows the manual addition of network links to such devices.

Enter the IP address and physical port of each side of the link. The port should be given in the full port name format (e.g. FastEthernet1/1, as it appears on the network device).

To delete a particular link, fill in its “ip address/port” for both sides, select the “remove” option and click “OK” button.

To delete ALL links, select the “delete all” option and click the “OK” button.
