Creating a Class Map

Command
awplus> enable
awplus# configure terminal
awplus(config)# class-map cmap1
awplus(config-cmap)#
Filtering
Incoming Traffic
To Do this Task
Use an ACL group name or group number
as a matching criterion for IPv4 ACLs only.
Use the specified CoS value as a matching
criterion.
To define filtering criteria, you need to create a class map. You create a
class map and then add it to a policy map to define an action for the
matched traffic. (This is the example shown in this section.) Or, you can
create a class map after you create a policy map. It is important to
understand that class maps filter incoming packets only.
For more information about the CLASS-MAP command, see "CLASS-
MAP" on page 1601.
The following example creates a class map named "cmap1" and enters the
Class Map mode. It is only within the Class Map mode that you can add
filters to the class map.

Table 193. Creating a Class Map

The following sections describe the extensive list of filtering options
available within a class map and provide configuration examples:

"Filtering Incoming Traffic" on page 1645

"Filtering Procedures" on page 1646
After you create a class map, you want to filter incoming traffic by placing
matching criteria on the class map. All of the QoS filtering commands
begin with "MATCH." There are ten commands that allow you to set
matching criteria for a class map. See Table 194.
