This section contains the following:
Creating and Configuring an Enforce-Rule
Every service class name that needs to be monitored will be linked with an enforce-rule. An enforce-rule
defines the monitoring duration, the sample rate, the penalty period, and the registered service class name that
the enforce-rule is linked to and the enforced service class name.
Use the procedure given below to create and configure an enforce-rule. An enforce-rule does not become
active until the enabled command is given.
Before You Begin
• The registered and enforced service (QoS) profiles must be created on the CMTS before creating an

previously configured enforced QoS profile. Any cable modems that enter the penalty period after
this configuration change, however, use the new enforced QoS profile.
QoS profile does not remain in force when a cable modem reboots. Instead, when the cable modem
reboots and reregisters with the Cisco CMTS, the CMTS assigns it the QoS profile that is specified in
its DOCSIS configuration file.
enforce-rule that uses those profiles. If you want to manage a cable modem that currently uses a
modem-created QoS profile, you must first manually create a new QoS profile on the CMTS with the
same QoS parameters as the modem-created profile. Then allow the modem to come online using the
manually created profile before beginning this procedure.
◦ To display quality of service (QoS) profiles for a Cisco CMTS, use the show cable qos profile
command in privileged EXEC mode.
◦ To configure a QoS profile, use the cable qos profile command in global configuration mode. To
set a particular value to its default, or to delete the profile when no specific parameters have been
set, use the no form of this command.
◦ Only DOCSIS 1.1 modems that register with a service class name are monitored.
◦ To ensure that the DOCSIS 1.1 service flow counters remain across a reboot of the CM, configure
the cable primary-sflow-qos11 keep all global configuration command.
