Patent attributes
This disclosure is directed to a method, system, and device for disabling links within a computer network based on a loop link priority parameter. The method includes detecting a loop in a network in a network communication device having multiple interfaces associated with different priorities. The device may transmit a first network packet as a loop check packet outbound from the network communication device via a first interface port. The device may then receive a second network packet (which may be the first outbound packet returning inappropriately to the device) as an inbound network communication via a second interface port. If the device identifies return of a sent loop check packet, it may disable one of the first interface port or the second interface port based on a comparison of loop link priority parameters to remove the loop in the network.
