Configuring Protocol Prioritization on an ATM Circuit

You can set priorities for the traffic sent across a HSSI and an ATM line interface

using protocol prioritization.

You must configure protocol prioritization on both a HSSI line interface and an

ATM circuit (interface). For ATM, you can use protocol prioritization for IP traffic

travelling over an ATM PVC.

The steps required to configure protocol prioritization for ATM differ from the

steps for all other circuit types. For instructions on configuring protocol

prioritization on an ATM circuit, see “Configuring Protocol Priority on ATM

Interfaces” on page 9-5.

For more information about protocol prioritization and how to configure an

outbound traffic filter with a priority queue action, see Chapter 7.

Tuning Protocol Prioritization

When you enable Protocol Priority on a circuit, the router uses default values that

help determine how priority filters work. These defaults are designed to work well

for most configurations. However, you can customize (or tune) protocol

prioritization to maximize its impact on your network.

This section covers the following topics:

• Tuning Concepts

• Editing Protocol Prioritization Parameters

• Monitoring Protocol Prioritization Statistics

Tuning Concepts

How you tune protocol prioritization depends on whether you are using the

bandwidth allocation algorithm or strict dequeuing algorithm. (See “The

Dequeuing Process” on page 2-3.)

Note:

You cannot change the percent of bandwidth for the priority queues

when configuring protocol prioritization over ATM at the interface level.
