class-map

To create a class map to be used for matching packets to the class whose name you specify and to enter
class-map configuration mode, use the class-map global configuration command. To delete an existing
class map and to return to global configuration mode, use the no form of this command.

Command History Release

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. Packets are checked against the match criteria
configured for a class map to decide if the packet belongs to that class. If a packet matches the specified
criteria, the packet is considered a member of the class and is forwarded according to the quality of
service (QoS) specifications set in the traffic policy.
After you enter the class-map command, the switch enters class-map configuration mode, and these
configuration commands are available:
•
