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

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

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

Context

A traffic policy is configured by binding traffic classifiers to traffic behaviors. The switch 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.

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

Pre-configuration Tasks

Before configuring a traffic policy to implement intra-VLAN Layer 2 isolation, perform the task of assign VLANs.

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 "Packet Filtering Configuration" in the S12700 V200R010C00 Configuration Guide - QoS.

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

    For details about how to configure an ACL-based simplified traffic policy, see Configuring ACL-based Packet Filtering in "ACL-based Simplified Traffic Policy Configuration" in the S12700 V200R010C00 Configuration Guide - QoS.
