match (class-map configuration)

Use the match class-map configuration command on the switch stack or on a standalone switch to define
the match criteria to classify traffic. Use the no form of this command to remove the match criteria.

access-group
acl-index-or-name
ip dscp dscp-list
ip precedence
ip-precedence-list
Defaults No match criteria are defined.
Command Modes Class-map configuration
Command History Release
12.1(11)AX
Usage Guidelines The match command is used to specify which fields in the incoming packets are examined to classify
the packets. Only the IP access group or the MAC access group matching to the Ether Type/Len are
supported.
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.
For the match ip dscp dscp-list or the match ip precedence ip-precedence-list command, you can enter
a mnemonic name for a commonly-used value. For example, you can enter the match ip dscp af11
command, which is the same as entering the match ip dscp 10 command. You can enter the match ip
precedence critical command, which is the same as entering the match ip precedence 5 command. For
a list of supported mnemonics, enter the match ip dscp ? or the match ip precedence ? command to
see the command-line help strings.
