Command History
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.
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.
After you are in quality of service (QoS) class-map configuration mode, these configuration commands
are available:
• description: describes the class map (up to 200 characters). The show class-map privileged EXEC
command displays the description and the name of the class-map.
• exit: exits from QoS class-map configuration mode.
• match: configures classification criteria. For more information, see the match (class-map
configuration) command.
• no: removes a match statement from a class map.
• rename: renames the current class map. If you rename a class map with a name that is already in
use, this message appears:
A class-map with this name already exists
match-all (Optional) Perform a logical-AND of all matching statements under this class
map. All criteria in the class map must be matched.
match-any (Optional) Perform a logical-OR of the matching statements under this class
map. One or more criteria must be matched.
class-map-name Name of the class map.
