Chapter 1 Configuring QoS
Configuring Standard QoS
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 1-16 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 | class-default ] 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.
A class-default traffic class is pre-defined and can be added to any
policy. It is always placed at the end of a policy map. With an implied
match any included in the class-default class, all packets that have not
already matched the other traffic classes will match class-default .
