Configuring a Traffic Policy to Implement Intra-VLAN Layer 2 Isolation

Configuring a Traffic Policy to Implement Intra-VLAN Layer 2 Isolation

Context

After VLANs are assigned, users in the same VLAN can communication with each other. If users in a VLAN need to be isolated unidirectionally or bidirectionally, configure a traffic policy.

A traffic policy is configured by binding traffic classifiers to traffic behaviors. The device classifies packets according to packet information, and associates a traffic classifier with a traffic behavior to reject the packets matching the traffic classifier, implementing intra-VLAN isolation.

Router provides intra-VLAN Layer 2 isolation based on MQC and based on the simplified ACL-based traffic policy.

Pre-configuration Tasks

Before configuring a traffic policy to implement intra-VLAN Layer 2 isolation, complete the following task:

Procedure

  • Configure MQC to implement intra-VLAN Layer 2 isolation.

    Perform the following MQC configurations to implement intra-VLAN Layer 2 isolation:
    • Specify permit or deny in the traffic behavior.
    • Apply the traffic policy to a VLAN or an interface that allows the VLAN.

    For details about how to configure MQC, see Configuring Packet Filtering in Huawei AR Series IOT Gateway Configuration Guide - QoS.

  • Configure a simplified ACL-based traffic policy to implement intra-VLAN Layer 2 isolation.
