Abstract
A mechanism for identifying link failures in a network is disclosed. To identifying link failures, a failed-link discovery mechanism receives information that represents a physical topology of the network. A management station that is associated with the network is identified and a path between one or more devices of the network and the management station is determined. For each link, a set of beyond link devices, that identifies only those devices that are beyond a particular link relative to the management station, is identified. Thereafter, a first message is sent to each active device within the network. Based on the responses that are returned in response to the first messages, a set of non-responding devices within the network is determined. The set of non-responding devices is then compared to each set of beyond link devices to identify link failures within the network.
