Description: The number of times a CM on this upstream channel has reset in Ranging states.
What is cadCmtsCmStatusMacNumRangFlaps?
This counter records how many times a cable modem on a specific upstream channel has reset while in the Ranging state, where it is synchronizing with the CMTS. Ranging flaps indicate instability in the initialization process and can be caused by signal quality problems or modem firmware issues. An operator monitors this to identify unreliable modems or upstream channel problems that degrade service.
