Configuring Standard QoS
Beginning in privileged EXEC mode, follow these steps to create a hierarchical policy map:
Command
Step 1
configure terminal
class-map [match-all | match-any]
Step 2

match {access-group acl-index-or-name |
Step 3
ip dscp dscp-list | ip precedence
ip-precedence-list}

Purpose
Enter global configuration mode.
Create a VLAN-level class map, and enter class-map configuration
mode. For information about creating a class map, see the
Traffic by Using Class Maps" section on page
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. See
the "Creating Named Standard and Extended ACLs" section on
page 37-15 for limitations when using the match-all and the
match-any keywords.
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.
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.
