| 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. |
