Supplemental
Information
Decreasing this parameter will increase the overhead on the entire system. Increasing this parameter can significantly increase the
time for a cable modem to re-register after an outage.
When changing this parameter, one should also consider the ranging backoff parameter which is configured per upstream channel.
Ranging backoff defines the number of broadcast ranging opportunities that a cable modem must wait after experiencing a
contention. If you increase the insertion interval, you will increase the time it takes cable modems to range and register. You may
choose to lower the ranging-backoff parameter to offset that.
To reset the default value, use the no option.
Parameters
<mac>
The MAC identifier. Valid numbers are 0-415.
<centiseconds>
Maximum permissible value is 2000. Valid range is 0 to 200 centiseconds.
Default is set at 40 centiseconds
