Map-timer
The Map-timer parameter sets the time interval between the CMTS
transmission of MAP messages for each active upstream channel. Acceptable
values are 1000 – 10000 microseconds. The default is 10 milliseconds.
Setting this value at less than 6 milliseconds causes performance problems.
Perform the following task to set the Map-timer parameter for the current
cable interface.
Periodic-Ranging-Interval
The Periodic-Ranging-Interval parameter defines the period during which the
CMTS will offer a ranging opportunity to each cable modem. By default,
Periodic Ranging is sent every 15 seconds. Acceptable values are 5 to 30
seconds.
You set the Periodic-ranging-interval for the current cable interface by
performing the following tasks.
Task Command
1. Enter interface cable mode. interface cable <c/s/i>
2. Configure Map Timer. map-timer <value>
