Abstract
An inter-networking device comprises a plurality of ports. Each port is operable to communicatively couple the inter-networking device to a respective ETHERNET segment. The inter-networking device further comprises ETHERNET link-integrity test functionality to determine a link status of a first port included in the plurality of ports. The inter-networking device monitors the link status of the first port. When the link status of the first port changes, the inter-networking device sends update information to at least one port included in the plurality of ports other than the first port indicating that the link status of the first port has changed.
