Object
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 count may indicate:
Intermittent downstream sync loss, or
DHCP or modem registration problems.
The Flap Count (ccsFlapTotal) will be incremented when this
counter is incremented.
Discontinuites in the value of this counter can occur if
this entry is removed from the table and then re-added, and
are indicated by a change in the value of
ccsFlapCreateTime.
