Abstract

A network process that automatically identifies and isolates faulty stations or group of stations within a token ring communication network by a process running on an agent that is remote from the beaconing token ring network. Beacon frame counters and good frame counters are maintained by a probe station within the token ring network which provides the counter information to an agent running at a remote location. The remote agent detects a beaconing station in the network by either an incrementing of the beacon frame counter or a failure to increment of the good frame counter within predetermined amounts of time. Once a token ring network segment is determined to be beaconing, an iterative process proceeds through the token ring with commands sent from the remotely operating agent. Stations on the network are iteratively wrapped and unwrapped until the beaconing stations can be determined and isolated from the network.
