Cisco CMTS Configuration Commands
An enforced QoS profile must have been already created on the CMTS before you can assign it to an
enforce-rule. If the rule does not exist, the system displays an error message.
When the no-persistence option is specified, the enforced QoS profile is still automatically applied to
subscribers that violate their bandwidth requirements. However, when the cable modem reboots, the
Cisco CMTS allows the cable modem to use the QoS profile that is specified in its DOCSIS
configuration file.
The no-persistence option can be used when initially using the subscriber traffic management option so
as to identify potential problem applications and users. When repeat offenders are identified, they can
then be assigned enforce-rules that do not use the no-persistence option, so that they remain in the
penalty period even if they reboot their cable modems.
The system automatically applies the enforced QoS profile to violators only if the enforce option has

Examples
The following example shows profile 12 being assigned as the enforced QoS profile to an enforce-rule:
Router# configure terminal
Router(config)# cable qos enforce-rule residential
Router(enforce-rule)# enforced qos-profile 12
Router(enforce-rule)# exit
Router(config)#
The following example shows profile 12 being assigned as the enforced QoS profile to an enforce-rule,
but with the no-persistence option specified, so that the enforced QoS profile does not remain in force
if the cable modem reboots:
Router# configure terminal
Router(config)# cable qos enforce-rule residential
Router(enforce-rule)# enforced qos-profile 12 no-persistence
Router(enforce-rule)# exit
Router(config)#
The following example shows the error message that is displayed when the specified QoS profile does
not exist on the CMTS:
Router# configure terminal
Router(config)# cable qos enforce-rule test
Router(enforce-rule)# enforced qos-profile 98
The qos profile 98 doesn't exist or it's a cm created QoS profile
Router(enforce-rule)#
