Configuring Ingress Hierarchical CoS on MPC and MIC Interfaces

You can configure ingress CoS parameters, including hierarchical schedulers, on MX Series routers with MPC/MIC interfaces. In general, the supported configuration statements apply to per-unit schedulers or to hierarchical schedulers.

Note: Ingress CoS is not supported on AE interfaces on MPCs.

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-bandwidth-share (proportional value | equal);input-scheduler-map map-name;input-shaping-rate rate;input-traffic-control-profile profile-name;

unit logical-unit-number;input-scheduler-map map-name;input-shaping-rate (percent percentage | rate);input-traffic-control-profile profile-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-traffic-control-profile profile-name;input-traffic-control-profile-remaining profile-name;interface interface-name {input-excess-bandwidth-share (proportional value | equal);input-traffic-control-profile profile-name;input-traffic-control-profile-remaining profile-name;unit logical-unit-number;}}

By default, ingress CoS features are disabled on the MPC and MIC interfaces.

You must configure the traffic-manager statement with ingress-and-egress mode to enable ingress CoS on the MPC/MIC interface, as shown in the following example:

chassis {fpc 7 {pic 0 {traffic-manager {mode ingress-and-egress;}}}}

Configured CoS features on the ingress are independent of CoS features on the egress. Note that for MIC-based MX80 routers, only one MIC can be configured for ingress queuing.

The following behavior aggregate (BA) classification tables are supported on the ingress side of the MPC/MIC interfaces:

DSCP
DSCP for IPv6
exp (MPLS)
IEEE 802.1p
inet-precedence
