Troubleshooting Cable Flap Lists
The Cisco uBR7100 series maintains a database of flapping cable modems to assist in locating cable
plant problems. The flapping cable interface 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 interface flap list keeps track of:
• the cable interface MAC address
• up and down transitions
• registration events
• missed periodic ranging packets
• upstream power adjustments
• the physical interface on the Cisco uBR7100 series CMTS
