How Do I Apply a Traffic Policy to a VLANIF Interface to Allow only TCP Packets in ESTABLISHED State to Pass Through?

Only the CE12800E equipped with FD-X series cards, CE6850HI, CE6850U-HI, CE6851HI, CE6855HI, CE6856HI, CE6857EI, CE6860EI, CE6865EI, CE7850EI, CE7855EI, CE8850EI, CE8861EI, CE8868EI, and CE8860EI support this mode.

Networking Requirements

You want to apply a traffic policy to allow only TCP packets in ESTABLISHED state to be sent from VLANIF 30 to VLANIF 150 and discard other packets sent in this direction.


  1. Configure the traffic classifiers c1, c2, and c3.

    <HUAWEI> system-view
    [~HUAWEI] acl 3000
    [*HUAWEI-acl4-advance-3000] rule permit tcp tcp-flag established  
    [*HUAWEI-acl4-advance-3000] quit
    [*HUAWEI] traffic classifier c1
    [*HUAWEI-classifier-c1] if-match acl 3000
    [*HUAWEI-classifier-c1] quit
    [*HUAWEI] traffic classifier c2
    [*HUAWEI-classifier-c2] if-match vlan 30                          
    [*HUAWEI-classifier-c2] quit
    [*HUAWEI] traffic classifier c3
    [*HUAWEI-classifier-c3] if-match qos-local-id 1                   
    [*HUAWEI-classifier-c3] quit
    [*HUAWEI] commit
  2. Configure traffic behaviors b1, b2, and b3.

    [~HUAWEI] traffic behavior b1
    [*HUAWEI-behavior-b1] permit                                      
    [*HUAWEI-behavior-b1] quit
    [*HUAWEI] traffic behavior b2
    [*HUAWEI-behavior-b2] remark qos-local-id 1                       
    [*HUAWEI-behavior-b2] quit
    [*HUAWEI] traffic behavior b3
    [*HUAWEI-behavior-b3] deny                                        
    [*HUAWEI-behavior-b3] quit
    [*HUAWEI] commit
  3. Configure traffic policies p1 and p2.

    [~HUAWEI] traffic policy p1
    [*HUAWEI-trafficpolicy-p1] classifier c1 behavior b1 precedence 1 
    [*HUAWEI-trafficpolicy-p1] classifier c2 behavior b2 precedence 5 
    [*HUAWEI-trafficpolicy-p1] quit
    [~HUAWEI] traffic policy p2
    [*HUAWEI-trafficpolicy-p2] classifier c3 behavior b3              
    [*HUAWEI-trafficpolicy-p2] quit
    [*HUAWEI] commit
  4. Apply the traffic policy p1 in the inbound direction of VLANIF 30.

    [~HUAWEI] interface Vlanif 30
    [~HUAWEI-Vlanif30] traffic-policy p1 inbound
    [*HUAWEI] commit
  5. Apply the traffic policy p2 in the outbound direction of VLANIF 150.

    [~HUAWEI] interface Vlanif 150
    [~HUAWEI-Vlanif150] traffic-policy p2 outbound
    [*HUAWEI] commit
