Troubleshooting Using Cable Flap Lists
The Cisco uBR7200 series universalbroadband routers maintain a database of flapping cable modems
to assist in locating cable plant problems. The flappingcable modem detector tracks the upstream and
downstream performance of all cable modems on the network, without impacting throughput and
performance,or creating additional packet overhead on the broadband network. The cable modem flap
