Example for Configuring Traffic Statistics

Networking Requirements

As shown in Figure 13-40, the tenant device is connected to the external network device through the Switch Module on the data center network. 802.1p priorities of storage service packets and data service packets are 6 and 2 respectively. The tenant requires that statistics on storage service packets be collected to determine bandwidth allocation.

Configuration Roadmap
The traffic statistics function is enabled so that the Switch Module can collect statistics on storage service packets. The configuration roadmap is as follows:
  1. Create VLANs and configure interfaces so that the Switch Module can connect to external network devices.
  2. Configure an ACL to match packets with 802.1p priorities of 6.
  3. Configure a traffic classifier and reference the ACL in the traffic classifier.
  4. Configure a traffic behavior so that the Switch Module collects statistics on packets matching rules.
  5. Configure a traffic policy, bind the traffic policy to the traffic classifier and traffic behavior, and apply the traffic policy to 10GE1/17/2 in the inbound direction so that the Switch Module collects statistics on packets with 802.1p priorities of 6.


  1. Create a VLAN and configure interfaces.

    # Create VLAN 100.

    <HUAWEI> system-view
    [~HUAWEI] sysname Switch Module
    [*HUAWEI] commit
    [~Switch Module] vlan 100
    [*Switch Module-vlan100] quit
    [*Switch Module] commit

    # Configure 10GE1/17/1 on the Switch Module as a trunk interface and add 10GE1/17/1 and 10GE1/17/2 to VLAN 100.

    [~Switch Module] interface 10ge 1/17/1
    [~Switch Module-10GE1/17/1] port link-type trunk
    [*Switch Module-10GE1/17/1] port trunk allow-pass vlan 100
    [*Switch Module-10GE1/17/1] quit
    [*Switch Module] interface 10ge 1/17/2
    [*Switch Module-10GE1/17/2] port default vlan 100
    [*Switch Module-10GE1/17/2] quit
    [*Switch Module] commit

  2. Configure an ACL.

    # Create ACL 4000 (Layer 2 ACL) on the Switch Module to match packets with 802.1p priorities of 6.

    [~Switch Module] acl 4000
    [*Switch Module-acl-L2-4000] rule permit 8021p 6
    [*Switch Module-acl-L2-4000] quit
    [*Switch Module] commit

  3. Configure a traffic classifier.

    Create a traffic classifier c1 on the Switch Module and reference ACL 4000 in the traffic classifier.

    [~Switch Module] traffic classifier c1
    [*Switch Module-classifier-c1] if-match acl 4000
    [*Switch Module-classifier-c1] quit
    [*Switch Module] commit

  4. Configure a traffic behavior.

    # Create a traffic behavior b1 on the Switch Module and configure the traffic statistics action in the traffic behavior.

    [~Switch Module] traffic behavior b1
    [*Switch Module-behavior-b1] statistics enable
    [*Switch Module-behavior-b1] quit
    [*Switch Module] commit

  5. Configure a traffic policy and apply the traffic policy to an interface.

    # Create a traffic policy p1 on the Switch Module and bind the traffic policy to the traffic classifier and traffic behavior.

    [~Switch Module] traffic policy p1
    [*Switch Module-trafficpolicy-p1] classifier c1 behavior b1
    [*Switch Module-trafficpolicy-p1] quit
    [*Switch Module] commit

    # Apply the traffic policy p1 to the inbound direction of 10GE1/17/2.

    [~Switch Module] interface 10ge 1/17/2
    [~Switch Module-10GE1/17/2] traffic-policy p1 inbound
    [*Switch Module-10GE1/17/2] quit
    [*Switch Module] commit
    [*Switch Module] quit

  6. Verify the configuration.

    # View the ACL configuration.

    <Switch Module> display acl 4000
    L2 ACL 4000, 1 rule
    ACL's step is 5
     rule 5 permit 8021p 6 (0 times matched)

    # View the traffic classifier configuration.

    <Switch Module> display traffic classifier c1
      Traffic Classifier Information:
        Classifier: c1
          Type: OR
            if-match acl 4000

    # View the traffic policy configuration.

    <Switch Module> display traffic policy p1
      Traffic Policy Information:
        Policy: p1
          Classifier: c1
            Type: OR
          Behavior: b1
            Statistics: enable

    # View the traffic statistics.
