Configuring CoS Three-Level Hierarchical Scheduling for MPLS Pseudowire Subscriber Interfaces (Logical Interfaces over a Pseudowire Interface Set)

Before configuring three-level scheduling on pseudowire logical interfaces over a pseudowire logical interface set, you must first complete the following tasks:

1. Configure the pseudowire logical interfaces. See Configuring a Pseudowire Subscriber Logical Interface.
2. Configure the pseudowire device count. See Configuring the Maximum Number of Pseudowire Logical Interface Devices Supported on the Router.
3. Configure the pseudowire device including the logical tunnel anchor point. See Configuring a Pseudowire Subscriber Logical Interface Device.
4. Configure the pseudowire transport logical interface. See Configuring the Transport Logical Interface for a Pseudowire Subscriber Logical Interface.
5. Configure the pseudowire signaling (either Layer 2 circuit signaling or Layer 2 VPN signaling). See Configuring Layer 2 Circuit Signaling for Pseudowire Subscriber Logical Interfaces or Configuring Layer 2 VPN Signaling for Pseudowire Subscriber Logical Interfaces.
6. Configure the pseudowire logical interfaces. See Configuring the Service Logical Interface for a Pseudowire Subscriber Logical Interface.

1. Configure the hierarchical scheduler for the physical interface used for the logical tunnel (anchor point). For three-level scheduling the hierarchical scheduler must be set to implicit-hierarchy.
   [edit]user@host#edit interfaces ps-anchor-device-nameuser@host#set hierarchical-scheduler implicit-hierarchy
2. Specify the traffic-control profile to use on the pseudowire logical interfaces.
   [edit class-of-service]user@host#edit interfaces ps ps-device-name user@host#edit unit logical-unit-numberuser@host#set output-traffic-control-profile profile-name
3. Define a pseudowire logical interface set and configure the traffic-control profile used for the interface set.
   [edit class-of-service]user@host#edit interfacesuser@host#edit interface-set interface-set-nameuser@host#edit output-traffic-control-profile profile-name
4. Group the pseudowire logical interfaces in the pseudowire logical interface set.
   [edit ]user@host#edit interfacesuser@host#edit interface-set interface-set-nameuser@host#edit interface ps ps-device-name user@host#edit unit logical-unit-number
5. Configure the rewrite rule.

   The available rewrite rule types for pseudowire interfaces are dscp and inet-precedence.

   [edit class-of-service]user@host#edit interfaces ps ps-device-name user@host#edit unit logical-unit-numberuser@host#edit rewrite-rules (dscp | inet-precedence) rewrite-nameuser@host#edit forwarding-class class-nameuser@host#set loss-priority class-name code-point (alias | bits)
6. Configure the classifier.

   The available classifier types for pseudowire interfaces are dscp and inet-precedence.

   [edit class-of-service]user@host#edit interfaces ps ps-device-name user@host#edit unit logical-unit-numberuser@host#edit classifiers (dscp | inet-precedence) classifier-nameuser@host#edit forwarding-class class-nameuser@host#set loss-priority class-name code-points [aliases] [bit-patterns]
7. Apply the rewrite rule and classifier to the pseudowire interfaces.

   For the interface_name parameter, specify the ps device name.

   [edit class-of-service interfaces interface_name unit logical-unit-number]user@host#set rewrite-rule (dscp | inet-precedence) (rewrite-name | default) protocol protocol-typesuser@host#set classifiers (dscp | inet-precedence) (classifier-name | default)
