Overview

Overview
An access egress policy defines the queuing for the traffic egressing on the access ports. Access-
egress queue policies are used at the Ethernet port and define the bandwidth distribution for the
various FC/queue traffic egressing on the Ethernet port.
There is one default access egress policy which is identified as policy ID 1. Each policy has 8
queues available. The Forwarding Class to queue mapping is predefined and cannot be changed.
The queue parameters like CIR, PIR, etc. can be modified. The default policy can be copied but
they cannot be deleted or modified.

Basic Configurations

A basic access egress QoS policy must conform to the following:
•
•
•

Create Access Egress QoS Policies

Configuring and applying QoS policies is optional. If no QoS policy is explicitly applied to an
access port, a default QoS policy 1 is applied.

Access Egress QoS Policy

To create an access egress policy, you must define the following:
•
•
•
•
•
Page 338
Have a unique access egress QoS policy ID.
Have a QoS policy scope of template or exclusive.
Queue parameters can be modified, but not deleted.
A new policy ID value. The system will not dynamically assign a value.
Specify the scope. A QoS policy must be defined as having either an exclusive scope for
use with a single port, or a template scope which enables its use with multiple access
ports.
Include a description. The description provides a brief overview of policy features.
By default all FCs are mapped to 8 queues available at the port according to
Forwarding Class to Queue-ID Map, on page
Remark - By default, remarking is disabled. If remarking is enabled by default 'use-dot1p'
is used and the Dot1p values in the customer packets which are egressing on this access
82.
