Chapter 36 Configuring QoS
Configuring Standard QoS
• If you enter or have used the set ip dscp command, the switch changes this command to set dscp in
its configuration.
• You can use the set ip precedence or the set precedence policy-map class configuration command
to change the packet IP precedence value. This setting appears as set ip precedence in the switch
configuration.
• You can configure a separate second-level policy map for each class defined for the port. The
second-level policy map specifies the police action to take for each traffic class. For information on
configuring a hierarchical policy map, see Classifying, Policing, and Marking Traffic on SVIs by
Using Hierarchical Policy Maps, page 36-58.
Beginning in privileged EXEC mode, follow these steps to create a nonhierarchical 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 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.
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 34-15 for limitations when using the match-all and the
match-any keywords.
Step 3
policy-map policy-map-name Create a policy map by entering the policy map name, and enter
policy-map configuration mode.
By default, no policy maps are defined.
The default behavior of a policy map is to set the DSCP to 0 if the
packet is an IP packet and to set the CoS to 0 if the packet is tagged.
No policing is performed.
Step 4
class class-map-name Define a traffic classification, and enter policy-map class configuration
mode.
By default, no policy map class-maps are defined.
If a traffic class has already been defined by using the class-map global
configuration command, specify its name for class-map-name in this
command.
