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
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.
