Example for Configuring Complex Traffic Classification on QinQ Termination Sub-interfaces

This section provides an example of how to configure complex traffic classification on QinQ termination sub-interfaces.

Networking Requirements

On the network shown in Figure 1, SwitchA is connected to the operator network through Device A. SwitchB is connected to the operator network through Device B. Complex traffic classification is configured on GE 0/1/8.1 (a QinQ termination sub-interface) of Device A to limit the rate of traffic sent by users attached to SwitchA to 10 Mbit/s and limit the CBS to 150000 bytes.

For details on how to configure QinQ termination sub-interfaces, see the chapter "QinQ Configuration" in the HUAWEI NetEngine 8000 F Series Router Configuration Guide - LAN Access and MAN Access.

Interfaces 1 through 2 in this example are GE 0/1/0, GE 0/1/8.1, respectively.

Figure 1 Network diagram for configuring complex traffic classification on QinQ termination sub-interfaces

Configuration Roadmap

The configuration roadmap is as follows:

Configure the GE0/1/8.1 interfaces on DeviceA and DeviceB as QinQ termination sub-interfaces.
Configure complex traffic classification-based traffic policing on the QinQ termination sub-interfaces.

Data Preparation

To complete the configuration, you need the following data:

IP address of each interface
Ranges of VLAN IDs in packet tags to be removed by QinQ termination sub-interfaces
Rate (10 Mbit/s) of traffic sent from users attached to SwitchA and CBS (150000 bytes)
Traffic classifier name, traffic behavior name, and traffic policy name, and interface to which the traffic policy is applied

Procedure

Configure an IGP on the backbone network. This example uses OSPF as an IGP. For details on how to configure OSPF, see the chapter "OSPF Configuration" in the HUAWEI NetEngine 8000 F Series Router Configuration Guide- IP Routing.

Verify the configuration.
After you apply the traffic policy to GE 0/1/8.1 of Device A, the sub-interface accepts only 10 Mbit/s traffic and discards nonconforming traffic.
