Policy Parameter Configuration

Policy Parameter Configuration

Context

A traffic policy is configured by binding traffic classifiers to traffic behaviors. A traffic classifier defines a group of matching rules to classify packets. A traffic behavior defines actions to be taken for the packets matching the traffic classifier, such as traffic statistics, traffic filtering, and re-marking.

Here, the binding between a traffic classifier and a traffic behavior is defined as classification. By default, the name of the traffic classifier or traffic behavior is the same as the classification name.

Procedure

  • Create a traffic policy.
    1. Choose QoS > Traffic Management > Policy Parameter Setting to open the Policy Parameter Setting page. The page shown in Figure 15-4 is displayed.

      Figure 15-4  Policy Parameter Setting

    2. Click Create in Policy Configuration List.
    3. On the Create Policy page, set parameters and configure the traffic classifier and traffic behavior. Table 15-2 describes the parameters. The page shown in Figure 15-5 is displayed.

      Enter the classification name. The traffic classifier and traffic behavior with the same name as the classification name are created by default.

      Figure 15-5  Create Policy

    4. Click Confirm to confirm the configurations. The page shown in Figure 15-6 is displayed.

      Figure 15-6  Finish Create Policy

    5. (Optional) Click Add Traffic Classifier, and select or enter parameters on the Add Traffic Classifier page. Click Confirm to confirm the configurations. The page shown in Figure 15-7 is displayed.

      To configure multiple traffic classifiers, repeat step 5.

      A traffic policy allows a maximum of 16 traffic classifiers.

      Item

      Description

      Policy name

      Indicates the name of a traffic policy.

      Classification 1

      Indicates the name of the binding between a traffic classifier and a traffic behavior. After parameters on the Create Policy page are set, click Confirm. The value of this field is updated automatically.

      Classification name

      Indicates the classification name.

      Rule relationship

      Indicates the relationship between rules in a traffic classifier:
      • OR: Packets match a traffic classifier as long as the packets match one or more rules in the traffic classifier.

      • AND: Packets match a traffic classifier only when the packets match all rules in the traffic classifier.

      Matched priority

      Indicates the priority used to match packets.
      • IP

      • 802.1p

      • DSCP

      Only one type of priority can be configured in each traffic classifier. A traffic classifier can define eight priority values. The relationship between multiple priority values is OR.

      IPv6 DSCP

      Indicates the DSCP priority is used to match IPv6 packets.

      Matched IPv4 ACL

      Indicates the IPv4 ACL used to match packets. You can configure a basic IPv4 ACL, advanced IPv4 ACL, or Layer 2 IPv4 ACL. If an IPv4 ACL contains multiple rules with different numbers, packets match the IPv4 ACL as long as the packets match one rule.

      Choose Security > ACL and configure an IPv4 ACL on the ACL page.

      Matched IPv6 ACL

      Indicates the IPv6 ACL used to match packets. You can configure a basic or advanced IPv6 ACL. If an IPv6 ACL contains multiple rules with different numbers, packets match the IPv6 ACL as long as the packets match one rule.

      Choose Security > ACL and configure an IPv6 ACL on the ACL page.

      Matched Layer 2 ACL

      Indicates the Layer 2 ACL used to match packets. If an Layer 2 ACL contains multiple rules with different numbers, packets match the Layer 2 ACL as long as the packets match one rule.

      Choose Security > ACL and configure an Layer 2 ACL on the ACL page.

      Advanced Classification Rule

      Indicates the advanced classification rule:
      • Layer 2 protocol: ARP, IP, MPLS, RARP, or user-defined protocol

      • Inbound interface

      Traffic filtering

      Indicates the traffic filtering action in a traffic behavior:
      • Permit: permits packets matching rules to pass through.

      • Deny: rejects packets matching rules.

      Traffic statistics

      Indicates the traffic statistics action in a traffic behavior:
      • Enable: enables traffic statistics.

      • Disable: disables traffic statistics.

      Configure Re-Marking

      Indicates the re-marking action in a traffic behavior. The device can re-mark DSCP priorities, 802.1p priorities, or local precedences in packets.

      Configure Traffic Policing

      Indicates the traffic policing action in a traffic behavior:
      • CIR (kbit/s): specifies the committed information rate (CIR), which is the guaranteed average transmission rate, in kbit/s.

      • CBS (byte): specifies the committed burst size (CBS), which is the average volume of burst traffic that can pass through an interface, in bytes.

      • PIR (kbit/s): specifies the peak information rate (PIR), which is the maximum transmission rate, in kbit/s.

      • PBS (byte): specifies the peak burst size (PBS), which is the maximum volume of burst traffic that can pass through an interface, in bytes.

      Configure Queue Scheduling

      Indicates the queue scheduling action in a traffic behavior. You can specify the queue type and assured bandwidth.

      Queue type

      Indicates the queue type in queue scheduling:
      • AF: AF ensures low drop probability of packets when the rate of outgoing service traffic does not exceed the minimum bandwidth. It is applied to services of heavy traffic that needs to be ensured.

      • EF: After packets matching traffic classification rules enter EF queues, they are scheduled in Strict Priority (SP) mode. Packets in other queues are scheduled only after all the packets in EF queues are scheduled. EF is applied to the services requiring the low delay, low drop probability, assured bandwidth, and occupying low bandwidth, for example, voice packets.

      • LLQ: LLQ queues are special type of EF queues and use the SP mode. The device uses traffic policing to process packets in LLQ queues, ensuring a short delay because traffic policing does not buffer packets.

      NOTE:

      Assured bandwidth is mandatory when Queue type is used.

      Assured bandwidth

      Indicates the assured bandwidth or bandwidth percentage:
      • The guaranteed bandwidth of an AF queue is the minimum bandwidth.

      • The guaranteed bandwidth of an EF queue is the minimum bandwidth.

      • The guaranteed bandwidth of an LLQ queue is the maximum bandwidth.

      When you configure assured bandwidth for queues of the same type in a traffic policy, use either the bandwidth value or bandwidth percentage. If you use both the bandwidth value and bandwidth percentage, the traffic policy may fail to be applied.

  • Modify a traffic policy.
    1. Choose QoS > Traffic Management > Policy Parameter Setting to open the Policy Parameter Setting page. The page shown in Figure 15-4 is displayed.
    2. In Policy Configuration List, select a traffic policy to be modified and click in the Operation column.
    3. On the Modify Policy, you can modify, add, or delete traffic classifiers. The page shown in Figure 15-8 is displayed.

      • To modify classification, select classification to be modified and configure parameters, as shown in Table 15-2. The values of Policy name and Classification name cannot be changed.

      • To add classification, click Add Traffic Classifier and configure parameters, as shown in Table 15-2.

      • To delete classification, select classification to be deleted, click , and click OK in the dialog box that is displayed. If the traffic policy contains only one classification, configured parameters are deleted and the name is restored to be Classification 1.
        NOTE:

        In Policy Configuration List, select the traffic policy to be modified, click , and click in the Operation column to delete classification.

      Figure 15-8  Modify Policy

    4. Click Confirm.
    5. Click OK to save the configurations.
  • Delete a traffic policy.
    1. Choose QoS > Traffic Management > Policy Parameter Setting to open the Policy Parameter Setting page. The page shown in Figure 15-4 is displayed.
    2. In Policy Configuration List, select a traffic policy and click Delete.
    3. Click OK in the displayed dialog box.

      If the traffic policy that you want to delete has been applied to an interface, unbind the traffic policy from the interface on the Policy Application tab page, and perform step 1 to step 3.
