To delete an existing policy map, use the no policy-map policy-map-name global configuration
command. To delete an existing class map, use the no class-map [match-all | match-any]
class-map-name global configuration command. To remove a match criterion, use the no match
{access-group acl-index-or-name | ip dscp | ip precedence} class-map configuration command.
This example shows how to configure the class map called class1. The class1 has one match criterion,
which is access list 103. It permits traffic from any host to any destination that matches a DSCP value
of 10.
Switch(config)# access-list 103 permit ip any any dscp 10
Switch(config)# class-map class1
Switch(config-cmap)# match access-group 103
Switch(config-cmap)# end
Switch#
This example shows how to create a class map called class2, which matches incoming traffic with DSCP
values of 10, 11, and 12.
Switch(config)# class-map class2

Purpose
Create a class map, and enter class-map configuration mode.
By default, no class maps are defined.
• (Optional) Use the match-all keyword to perform a logical-AND
of all matching statements under this class map. All match criteria
in the class map must be matched.
• (Optional) Use the match-any keyword to perform a logical-OR
of all matching statements under this class map. One or more
match criteria must be matched.
For class-map-name, specify the name of the class map.
•
If neither the match-all or match-any keyword is specified, the default
is match-all.
Because only one match command per class map is supported,
Note
the match-all and match-any keywords function the same.
Define the match criterion to classify traffic.
By default, no match criterion is defined.
Only one match criterion per class map is supported, and only one ACL
per class map is supported.
For access-group acl-index-or-name, specify the number or name
•
of the ACL created in Step 2.
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.
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.
Return to privileged EXEC mode.
Verify your entries.
(Optional) Save your entries in the configuration file.
