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-port 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 used,
the message
A class-map with this name already exists
appears.
To define packet classification on a physical-port basis, only one
match
command per class map is
supported. In this situation, the
match-all
and
match-any
keywords are equivalent.
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.
