Configuring Ingress Hierarchical CoS on MIC and MPC Interfaces

You can configure ingress CoS parameters, including hierarchical schedulers, on MIC and MPC interfaces on MX Series routers. 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 MIC and MPC interfaces. To enable ingress CoS on a MIC or MPC interface, configure the traffic-manager statement with ingress-and-egress mode 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 MIC and MPC interfaces:

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