Chapter 37 Configuring QoS
Configuring Standard QoS
• When you configure a default traffic class by using the class class-default policy-map configuration
command, unclassified traffic (traffic that does not meet the match criteria specified in the traffic
classes) is treated as belonging to the default traffic class (class-default).
Beginning in privileged EXEC mode, follow these steps to create a hierarchical policy map:
Command Purpose
Step 1
configure terminal Enter global configuration mode.
Step 2
class-map [match-all | match-any]
class-map-name
Create a VLAN-level class map, and enter class-map configuration
mode. For information about creating a class map, see the “Classifying
Traffic by Using Class Maps” section on page 37-54.
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 mat
ch-all or match-any keyword is specified, the default
is match-all.
Note Because only one match command per class map is supported,
the match-all and match-any keywords function the same. See
the “Creating Named Standard and Extended ACLs” section on
page 35-15 for limitations when using the mat
ch-all and the
match-any k
eywords.
Step 3
match {access-group acl-index-or-name |
ip dscp dscp-list | ip precedence
ip-precedence-list}
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
pe
r 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.
