Quality of Service (QoS) Commands

OL-32830-01 Command Line Interface Reference Guide

User Guidelines

The class-map command and its subcommands are used to define packet

classification, marking, and aggregate policing as part of a globally-named service

policy applied on a per-interface basis.

A class map consists of one or more ACLs. It defines a traffic flow by determining

which packets match some or all of the criteria specified in the ACLs.

All class map commands are only available when QoS is in advanced mode.

The class-map enters Class-map Configuration mode. In this mode, up to two

match commands can be entered to configure the criteria for this class. Each

match specifies an ACL.

When using a few match commands, each must point to a different type of ACL,

such as: one IP ACL, one IPv6 ACL, and one MAC ACL. The classification is by first

match, therefore, the order of the ACLs is important.

Error messages are generated in the following cases:

There is more than one

There is a repetitive classification field in the participating ACLs.

After entering the Class-map Configuration mode, the following configuration

commands are available:

exit: Exits the Class-map Configuration mode.

match: Configures classification criteria.

no: Removes a match statement from a class map.

The following example creates a class map called Class1 and configures it to

check that packets match all classification criteria in the ACL specified.

switchxxxxxx(config)# class-map

switchxxxxxx(config-cmap)# match access-group
