CoS Configuration Restrictions

The following restrictions apply to adaptive services CoS configuration:

The adaptive services interface does not support scheduling, only DiffServ marking and queue assignment. You must configure scheduling at the [edit class-of-service] hierarchy level on the output interface or fabric.
In the default configuration, queues 1 and 2 receive 0 percent bandwidth. If packets will be assigned to these queues, you must configure a scheduling map.
You must issue a commit full command before using custom forwarding-class names in the configuration.
Only the JUNOS standard DiffServ names can be used in the configuration. Custom names are not recognized.
