Applying a Traffic Policy

Procedure

1. Run system-view

   The system view is displayed.

2. Perform the following operations based on the interfaces on which a traffic policy is used:
   • Apply an MF classification-based traffic policy to a Layer 3 interface.
     1. To enter the Layer 3 interface view, run the interface interface-type interface-number command.
     2. (Optional) To apply an MF classification-based traffic policy to incoming traffic based on the source and destination QoS policy IDs, run the qppb-policy qos-local-id both inbound command.

        

        The if-match qos-local-id source source-qos-local-id destination destination-qos-local-id command must be run prior to the qppb-policy qos-local-id both inbound command. For details, see section defining a traffic classifier.

     3. To apply a traffic policy to the Layer 3 interface, run the traffic-policy policy-name { inbound | outbound } [ all-layer | link-layer | mpls-layer ] command.
        

        • If link-layer is configured, the device performs MF classification based on Layer 2 information of packets.
        • If mpls-layer is configured, the device performs MF classification based on MPLS packet header information.
        • If all-layer is configured, the device first performs MF classification based on Layer 2 information of packets. If packets do not match any rule based on Layer 2 information, the device performs MF classification based on Layer 3 information of packets.
   • Apply an MF classification-based traffic policy to a Layer 2 interface, with a VLAN ID range specified.
     1. To enter the Layer 3 interface view, run the interface interface-type interface-number command.
     2. To change the interface mode from Layer 3 to Layer 2, run the portswitch command.
     3. To add the Layer 2 interface to a specific VLAN in tagged mode, run the port trunk allow-pass vlan { { vlan-id1 [ to vlan-id2 ] } &<1-10> | all } command.
     4. To apply a traffic policy to the Layer 2 interface, run the traffic-policy policy-name { inbound | outbound } vlan { vlan-id1 [ to vlan-id2 ] | all } [ all-layer | link-layer | mpls-layer ] command.
   • Apply an MF classification-based traffic policy to an EVC Layer 2 sub-interface, with the bandwidth allocation mode specified.
     1. To enter the EVC Layer 2 sub-interface view, run the interface interface-type interface-number.subnum mode l2 command.
     2. To apply a traffic policy to the EVC Layer 2 sub-interface, run the traffic-policy policy-name { inbound | outbound } identifier { none | vid | ce-vid | vid-ce-vid } [ all-layer | link-layer | mpls-layer ] command.
        

        The bandwidth allocation mode specified using the identifier parameter must be the same as the one configured on the EVC Layer 2 sub-interface.

   • Apply an MF classification-based traffic policy to a QinQ VLAN tag termination sub-interface, with the PVLAN ID and CVLAN ID ranges specified.
     1. To enter the sub-interface view, run the interface interface-type interface-number.subinterface-number command.
     2. To set a VLAN ID range for the sub-interface and configure the sub-interface to remove the tags from double-tagged packets, run the encapsulation qinq-termination [ local-switch | rt-protocol ] command.
     3. To configure the sub-interface as a QinQ VLAN tag termination sub-interface, run the qinq termination pe-vid pe-vid [ to high-pe-vid ] ce-vid ce-vid [ to high-ce-vid ] [ vlan-group group-id ] command.
     4. To apply a traffic policy to the QinQ VLAN tag termination sub-interface, run the traffic-policy policy-name { inbound | outbound } pe-vid pe-vid ce-vid ce-vid1 [ to ce-vid2 ] [ all-layer | link-layer | mpls-layer ] command.
   • Apply an MF classification-based traffic policy to a VBDIF interface.
     1. To create a bridge domain (BD), run the bridge-domain bd-id command.
     2. To return to the system view, run the quit command.
     3. To create a VBDIF interface and enter the VBDIF interface view, run the interface vbdif bd-id command.
     4. To apply a traffic policy to the VBDIF interface, run the traffic-policy policy-name { inbound | outbound } command.
   • (Optional) Apply an MF classification-based traffic policy to a VPN instance.
     1. To enter the VPN instance view, run the ip vpn-instance vpn-instance-name command.
     2. To apply a traffic policy to the VPN instance, run the traffic-policy policy-name network inbound command.
   • (Optional) Apply an MF classification-based traffic policy to a VSI.
     1. To enter the VSI view, run the vsi vsi-name command.
     2. Perform either of the following operations as required:
        • Run the traffic-policy policy-name network inbound link-layer command to apply a network-side traffic policy to the VSI.
        • Run the traffic-policy policy-name ac-mode { inbound | outbound } [ link-layer | all-layer ] command to apply a user-side traffic policy to the VSI.
   • (Optional) Apply an MF classification-based traffic policy to an EVPN.
     1. To enter the EVPN view, run the evpn vpn-instance vpn-instance-name bd-mode command.
     2. To apply a traffic policy to the EVPN, run the traffic-policy policy-name network inbound command.

3. (Optional) Run qos traffic-car member-link-scheduler distribute in the Eth-Trunk interface view

   When CAR is configured on a trunk interface, the sum of all the member interfaces' bandwidth complies with the CAR settings.

4. Run commit

   The configuration is committed.
