Abstract
Methods and systems are described for detecting data path loops between ports on a device in a network system. Data path loops may be detected by first detecting data path loop characteristics exhibited by ports on a device. Upon detection of data path loop characteristics, the existence of a data path loop may be verified through the transmission of a broadcast packet through the potentially loopy ports. By first detecting characteristics of a data path loop and thereafter confirming the presence of a loop, the methods and systems described herein ensure that anomalies in data packet and/or port movement are not the product of configuration changes in the network system, but are instead the result of data path loops. By more intelligently identifying data path loops, false positives may be reduced.
