Abstract
A network has a plurality of devices connected together in pairs. When a physical connection between a pair of devices is initiated, the devices exchange information regarding a unique device identifier, and details of the physical connection. This information is provided in a report to a network manager. When a failure occurs on the network, the connection information is used to locate the failure.
