Command History
Usage Guidelines Use this command to specify the name of the class for which you want to create or to modify class-map
match criteria and to enter class-map configuration mode.
The switch supports a maximum of 1024 unique class maps.
You use the class-map command and class-map configuration mode to define packet classification as
part of a globally named service policy applied on a per-port basis. When you configure a class map, you
can use one or more match commands to specify match criteria. Packets arriving at either the input or
output interface (determined by how you configure the service-policy interface configuration command)
are checked against the class-map match criteria to determine if the packet belongs to that class.
A match-all class map means that the packet must match all entries and can have no other match
statements.
After you are in 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 QoS class-map configuration mode.
match-all (Optional) Perform a logical-AND of all matching statements under this class
map. Packets must meet all of the match criteria.
match-any (Optional) Perform a logical-OR of the matching statements under this class
map. Packets must meet one or more of the match criteria.
class-map-name Name of the class map.
