• The command is supported only on DOCSIS 1.1 CM primary service flows.
• You can specify the cable modem service-class-name command only after the CM has been online
for at least 200 seconds.
• The parameters defined by the named service class should always be a compatible subset of the
registered set of parameters for the CM. Only certain options can be changed using a CMTS router
service class, such as the max-rate, priority, or tos-overwrite options. The max-burst option in
both the enforced and registered CMTS router service classes must strictly match the value for
max-burst in the registered DOCSIS configuration file. If the service class value does not match,
then CM registration will fail with a reject-c state, or the enforced class will fail.
