[edit class-of-service] Hierarchy Level
This topic shows the complete configuration for class of service (CoS) statements for the [edit class-of-service] hierarchy level, listing all possible configuration statements and showing their level in the configuration hierarchy. When you are configuring the Junos OS, your current hierarchy level is shown in the banner on the line preceding the user@host# prompt.
For a complete list of the Junos configuration statements, see the Junos OS Hierarchy and RFC Reference.

On a Juniper Networks MX Series 3D Universal Edge Routers with Enhanced Queuing DPCs, you can configure the following CoS statements at the [edit class-of-service interfaces] hierarchy level:
interface-set interface-set-name {excess-bandwidth-share (proportional value | equal);internal-node;traffic-control-profiles profile-name;output-traffic-control-profile-remaining profile-name;}
