Traffic policy applications on S series switches

15

The following lists objects to which a traffic policy can be applied on S series switches (except the S1700):
- S series fixed switches: A traffic policy can be applied to the system, an interface, or a VLAN.
- S series modular switches: A traffic policy can be applied to the system, a card, an interface, or a VLAN.
If a traffic policy is applied to the system, it takes effect for all the traffic specified by the matching traffic classifiers in the system.
If a traffic policy is applied to an interface, a VLAN, or a card (only on a modular switch), it takes effect only for traffic specified by the matching traffic classifiers of the specified interface, VLAN, or card.
Note: MQC cannot be configured on the S2700SI.

How to delete an applied traffic policy on an S series switch
For S series switches (except the S1700), a traffic policy that is not applied can be deleted directly. To delete a traffic policy that has been applied, unbind the traffic policy and then delete it. Example 1: The traffic policy p1 has been applied in the inbound direction of GE1/0/1. Run the following commands to delete the traffic policy p1: [HUAWEI] interface GigabitEthernet 1/0/1 [HUAWEI-GigabitEthernet1/0/1] undo traffic-policy p1 inbound [HUAWEI-GigabitEthernet1/0/1] quit [HUAWEI] undo traffic policy p1 Example 2: The traffic policy p2 has been applied in the inbound direction of VLAN 100. Run the following commands to delete the traffic policy p2: [HUAWEI] vlan 100 [HUAWEI-vlan100] undo traffic-policy p2 inbound [HUAWEI-vlan100] quit [HUAWEI] undo traffic policy p2 Example 3: The traffic policy p3 has been applied in the inbound direction of the card in slot 6. Run the following commands to delete the traffic policy p3: [HUAWEI] undo traffic-policy p3 global inbound slot 6 [HUAWEI] undo traffic policy p3 Example 4: The traffic policy p4 has been applied in the inbound direction of the system. Run the following commands to delete the traffic policy p4: [HUAWEI] undo traffic-policy p4 global inbound [HUAWEI] undo traffic policy p4 Before deleting a traffic policy, ensure that you have unbound the traffic policy completely. You can run the display traffic-applied command to check information about applied traffic policies. Note: MQC cannot be configured on the S2700SI.
