QoS policy context

Syntax

no SEQ_NUM class ipv4|ipv6|mac CLASS_NAME action dscp|ip_precedence| priority |rate_limit

The QoS policy context is used to associate classes with policy actions. One is placed in this context after creating a QoS policy. Traffic that matches the rules in the class will have the specified QoS action applied. Traffic that matches an ignore statement in the class will not have an action applied. Traffic that does not match any entries will have the default-mac-class action applied. MAC classes cannot be configured in the same policy with IPv4 and IPv6 classes. The default-class is to be used with policies that contain IPv4 and IPv6 classes whereas the default-mac-class is to be used with MAC classes.
