Usage Guidelines Use this command to specify the name of the class for which you want to create or modify class-map
match criteria and to enter class-map configuration mode. In this mode, you can enter one match
command to configure the match criteria for this class.
The class-map command and its subcommands are used to define packet classification and marking as
part of a globally named service policy applied on a per-interface basis.
In quality of service (QoS) class-map configuration mode, these configuration commands are available:
•
•
•
Only one match criterion per class map is supported. For example, when defining a class map, only one
match command can be entered.
Only one access control list (ACL) can be configured in a class map. The ACL can have multiple access
control entries (ACEs).
The switch does not support any deny conditions in an ACL configured in a class map.
