Description: The number of times a Cable Modem registered more frequently than expected. Excessive registration is defined as the presence of a time span between two successive registration cycles which is less than a threshold span (ccsFlapInsertionTime).

A Cable Modem may fail the ranging or registration process due to not being able to get an IP address. When the Cable Modem can not finish registration within the insertion time, it retries the process and sends the Initial Maintenance packet again. CMTS will receive the Initial Maintenance packet from the Cable Modem sooner than expected and the Cable Modem is considered a flapping modem.

This object may indicate: Intermittent downstream sync loss, or DHCP or modem registration problems.

The Flap number (ccsFlapTotalNum) will be incremented when this object is incremented.

This object is going to replace the object ccsFlapInsertionFails and the value of this object can be reset to zero if this entry is removed from the table and then re-added, or if a user resets all the statistical objects for this entry. The value of the object ccsFlapLastResetTime indicates the last reset time.
