Shaping on Dialer Interfaces

The Shaping on Dialer Interfaces feature provides support for Point-to-Point Protocol over Ethernet (PPPoE) and Point-to-Point Protocol over Asynchronous Transfer Mode (PPPoA) configurations on dialer interfaces. The feature provides support for Modular QoS CLI (MQC)-based queuing and shaping that supports per-customer quality of service (QoS). Parent policies are attached to an Ethernet in the First Mile (EFM) interface, and child policies are attached to individual dialer interfaces. Class of service (CoS) values are set by applying a policy to the dialer interface. The feature also enables the collection of queuing statistics on the dialer interface and the polling of traffic counters for dialer interfaces.

Restrictions for Shaping on Dialer Interfaces

  • The output queueing policy must have a parent class-default shaper, and any other queueing actions must be configured in a child policy.

Information About Shaping on Dialer Interfaces

QoS on PPP Session on Dialer Interfaces

The Shaping on Dialer Interfaces feature consolidates the output queueing and classification on the egress interface (where all the queueing features are run). The police and set features (such as CoS marking) also work in the output path.

MQC-based QoS queuing and shaping features can be used to attach flat class-default shaped policies to the EFM and attach HQoS parent-shaped policies to the dialer interface.

Policies are applied to the dialer interface using the service-policy command. In addition the related show and debug commands display policy and queueing statistics associated with the dialer target.

QoS Dialer Interface Topology

The following figure shows the supported topology for the Shaping on Dialer Interfaces feature:

Figure 1. Shaping on Dialer Interfaces Topology

The Customer Premises Equipment (CPE) is shared between several customers. Each customer connects to the CPE through a VLAN on a Gigabit Ethernet port. The CPE connects to the service over a DSL using an EFM interface (this looks like an Ethernet connection but uses DSL) over which all the incoming VLANs will be forwarded. The traffic for each VLAN (customer) is transmitted in a separate PPP session. Each session is set up using a dialer interface.

How to Configure Shaping on Dialer Interfaces

Configuring an Output Queueing Policy for Dialer Interfaces

Before You Begin

Because the dialer target is added to the dynamic target API, the output queueing policy must have a parent class-default shaper with any other queueing actions configured in a child policy.
