Using Flap Lists to Troubleshoot CM Problems
The BSR maintains a database of flapping CMs to assist in locating cable plant
problems. The flap list feature tracks the upstream and downstream performance of all
CMs on the network, without impacting throughput and performance between the CM
and BSR, or creating additional packet overhead on the HFC network.
The following tasks are used to troubleshoot CM Problems:
• Viewing Flap List Statistics to Identify Network Health
• Interpreting Flap List Statistics
Note: If a value is set to the default, the default value does not display after a
show running-configuration command.
