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 communicate with each other. You must configure a traffic policy if users in a VLAN need to be isolated unidirectionally or bidirectionally.

Context

A QoS policy is configured by binding traffic classifiers to traffic behaviors. The switch implements intra-VLAN isolation by classifying packets according to packet information, and associating a traffic classifier with a traffic behavior to reject the packets matching the traffic classifier.

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

Pre-configuration Tasks

Before configuring a traffic policy to implement intra-VLAN Layer 2 isolation, perform the task of assigning 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 S1720, S2700, S5700, and S6720 V200R012(C00&C20) 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 S1720, S2700, S5700, and S6720 V200R012(C00&C20) Configuration Guide - QoS.
