Cisco CMTS Configuration Commands
monitoring-duration
To specify the time period and sample rate to be used for monitoring subscribers, use the monitoring-
duration command in enforce-rule configuration mode. To reset an enforce-rule to its default values,
use the no form of this command.
Syntax Description
minutes
sample-rate minutes
Defaults
The monitoring-duration value defaults to 360 minutes (6 hours), and the sample-interval value
defaults to 15 minutes.

Usage Guidelines
When you an enable an enforce-rule, the CMTS periodically checks the bandwidth being used by
subscribers, so as to determine whether any subscribers are consuming more bandwidth than that
specified by their registered QoS profile. The CMTS keeps track of the subscribers using a sliding
window that begins at each sample-rate interval and continues for the monitoring-duration period.
For example, with the default sample-rate interval of 15 minutes and the default monitoring-duration
window of 360 minutes, the CMTS samples the bandwidth usage every 15 minutes and determines the
total bytes transmitted at the end of each 360 minute period. Each sample-rate interval begins a new
sliding window period for which the CMTS keeps track of the total bytes transmitted.
The sample-rate interval must be less than or equal to the monitoring-duration period. If you attempt
Note
to set the sample-rate to a value greater than the monitor-duration period, the command is ignored and
the parameters are unchanged.

monitoring-duration minutes [sample-rate minutes]
no monitoring-duration
Modification
This command was introduced.
The minimum sample-rate was reduced to 1 minute. Also, the sample-rate
is not allowed to be set to a value greater than the monitor-duration period.
If you attempt to do so, the command is ignored and both parameters remain
set to their current values.
The valid range is 10 to 10080 minutes, with a default of 360 minutes
(6 hours).
(Optional) Rate of sampling, in minutes. The valid range is 1 to 30
minutes, with a default value of 15 minutes.
The sample-rate minutes must be less than or equal to the
Note
monitoring-duration minutes period.
