In a policy, multiple class-to-traffic-behavior mappings can be configured, and these mappings are
executed according to the order configured.
Follow these steps to define a policy:
To do… Use the command… Remarks
Enter system view system-view —
Create a policy and enter policy
view
qos policy policy-name Required
Specify the traffic behavior for a
class in the policy classifier tcl-name behavior
behavior-name
Required
Display the specified class and
its associated traffic behavior in
the QoS policy
display qos policy
user-defined [ policy-name
[ classifier tcl-name ] ]
Optional
Available in any view
If an ACL is referenced by a QoS policy for defining traffic match criteria, , packets matching the ACL
are organized as a class and the behavior defined in the QoS policy applies to the class regardless of
whether the match mode of the ACL clause is deny or permit .
QoS Policy Configuration Example
Network requirements
Configure a QoS policy test_policy to drop the packets with IP precedence 6.
Configuration procedure
# Create a class test_class to match the packets with IP precedence 6.
<Sysname> system-view
[Sysname] traffic classifier test_class
[Sysname-classifier-test_class] if-match ip-precedence 6
[Sysname-classifier-test_class] quit
# Create a traffic behavior test_behavior and configure the action of drop the packets for it.
[Sysname] traffic behavior test_behavior
[Sysname-behavior-test_behavior] filter deny
[Sysname-behavior-test_behavior] quit
# Create a QoS policy test_policy and associate the traffic behavior with the class.
[Sysname] qos policy test_policy
