You can configure ingress CoS parameters, including hierarchical schedulers, on MX-series routers with Enhanced Queuing DPCs. In general, the supported configuration statements apply to per-unit schedulers or to hierarchical schedulers.
To configure ingress CoS for per-unit schedulers, include the following statements at the [edit class-of-service interfaces interface-name] hierarchy level:
- [edit class-of-service interfaces interface-name]
- input-excess-bandwith-share (proportional value | equal);
- input-scheduler-map map-name;
- input-shaping-rate rate;
- input-traffic-control-profile profiler-name shared-instance instance-name;
- unit logical-unit-number;
- input-scheduler-map map-name;
- input-shaping-rate (percent percentage | rate);
- input-traffic-control-profile profile-name shared-instance instance-name;
- }
To configure ingress CoS for hierarchical schedulers, include the interface-set interface-set-name statement at the [edit class-of-service interfaces] hierarchy level:
- [edit class-of-service interfaces]
- interface-set interface-set-name {
- input-excess-bandwith-share (proportional value | equal);
- input-traffic-control-profile profiler-name shared-instance instance-name;
- input-traffic-control-profile-remaining profile-name;
-
- interface interface-name {
- input-excess-bandwith-share (proportional value | equal);
- input-traffic-control-profile profiler-name shared-instance instance-name;
- input-traffic-control-profile-remaining profile-name;
-
- unit logical-unit-number;
- input-traffic-control-profile profiler-name shared-instance instance-name;
- }
- }
- }
By default, ingress CoS features are disabled on the Enhanced Queuing DPC.
You must configure the traffic-manager statement with ingress-and-egress mode to enable ingress CoS on the ED DPC:
- [edit chassis fpc slot-number pic pic-number]
- traffic-manager mode ingress-and-egress;
Configured CoS features on the ingress are independent of CoS features on the egress except that:
The following behavior aggregate (BA) classification tables are supported on the ingress side of the Enhanced Queuing DPC:
