flap-list power-adj-threshold
Sets the cable flap list power adjustment threshold.
The system maintains a cable modem flap table for every cable modem (whether active or not)
that has difficulty communicating with the CMTS. Flapping refers to the rapid disconnecting and
reconnecting of cable modems. The flap list maintains a flap count and logs the most recent
flapping activity for each cable modem attached to the CMTS.
If a modem is already in the flap list, and requires a ranging adjustment greater than the
power-adj-threshold, then that modem’s power adjust count is incriminated in the flap list.
