Configuring traffic filtering
You can filter in or filter out traffic of a class by associating the class with a traffic filtering action. For
example, you can filter packets sourced from a specific IP address according to network status.
Configuration procedure
To configure traffic filtering:
Step Command Remarks
1. Enter system view. system-view N/A
2. Create a traffic class and
enter traffic class view. traffic classifier classifier-name [ operator
{ and | or } ] By default, no traffic class
exists.
3. Configure match criteria. if-match match-criteria
By default, no match criterion
is configured.
4. Return to system view. quit N/A
5. Create a traffic behavior
and enter traffic behavior
view. traffic behavior behavior-name
By default, no traffic behavior
exists.
6. Configure the traffic
filtering action.
filter { deny | permit }
By default, no traffic filtering
action is configured.
If a traffic behavior has the
filter deny action, all the other
actions except for class-based
accounting in the traffic
behavior do not take effect.
7. Return to system view. quit N/A
8. Create a QoS policy and
enter QoS policy view.
qos policy policy-name
By default, no QoS policy
exists.
9. Associate the traffic class
with the traffic behavior in
the QoS policy.
classifier classifier-name behavior
behavior-name
By default, a traffic class is not
associated with a traffic
behavior.
10. Return to system view. quit N/A
11. Apply the QoS policy.
• Applying the QoS policy to an
interface
• Applying the QoS policy to a VLAN
• Applying the QoS policy globally
• Applying the QoS policy to the control
plane
Choose one of the application
destinations as needed.
By default, no QoS policy is
applied.
