PurposeCommand or Action
(Optional) Specifies the IP protocol to which the class map applies:
match protocol [ip | ipv6]
Step 3
Example:
Switch(config-cmap)# match protocol
•
Use the argument ip to specify IPv4 traffic and ipv6 to specify IPv6
traffic.
•
When you use the match protocol command, only the match-all
keyword is supported for the class-map command.
ip
Defines the match criterion to classify traffic.
match {ip dscp dscp-list | ip precedence
ip-precedence-list}
Step 4
By default, no match criterion is defined.
Example:
Switch(config-cmap)# match ip dscp
•
For ip dscp dscp-list, enter a list of up to eight IP DSCP values to
match against incoming packets. Separate each value with a space.
The range is 0 to 63.
10
•
For ip precedence ip-precedence-list, enter a list of up to eight
IP-precedence values to match against incoming packets. Separate
each value with a space. The range is 0 to 7.
To remove a match criterion, use the no match {access-group
acl-index-or-name | ip dscp | ip precedence} class-map
configuration command.

Returns to privileged EXEC mode.end
Example:
Switch(config-cmap)# end
Step 5
Verifies your entries.show class-map
Example:
Switch# show class-map
Step 6
(Optional) Saves your entries in the configuration file.copy running-config startup-config
