System and Method for Detecting and Reporting Cable Modems with Duplicate Media Access Control Addresses |
摘要 |
The detection of devices with duplicate media access controller (MAC) addresses in a cable network may be accomplished by reference to a value indicative of a DOCSIS version supported by the device or by reference to a having a MAC address/giaddr pair. Where a version value is used, the detection of devices having duplicate MAC addresses looks for changes in the reported version value from a higher version to a lower version. Where MAC address/giaddr pairs are used, a centralized storage of historical cable modem MAC address/giaddr pair data is used to identify cable modems (CM's) that report duplicate MAC addresses. If duplication is detected, an appropriate remedial response is taken.
