Cisco Cable Spectrum Flap Insertion Fails

1.3.6.1.4.1.9.9.114.1.1.5.1.4

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.
