The interval for cdxCmtsCmOnOffNotification sent by CMTS
for one online/offline state change if
cdxCmtsCmOnOffTrapEnable is true.
If there are more than one state changes to online/offline
for a cable modem during this interval, only one
cdxCmtsCmOnOffNotification is sent by CMTS for the first
state change to online and one cdxCmtsCmOnOffNotification
for the first state changing to offline if
cdxCmtsCmOnOffTrapEnable is true.
This is to avoid too many notifications sent for a cable
modem online/offline state changes during a short period
of time.
If the value is 0, then cdxCmtsCmOnOffNotification will be
sent for every state changes to online/offline for a cable
modem if cdxCmtsCmOnOffTrapEnable is true.
If cdxCmtsCmOnOffTrapEnable value changes from true to
false or from false to true, this value will remain no
change as before.
The default value is 600 seconds.
