Configuration Task Description

Configuring VLAN Assignment

VLANs can isolate the hosts that do not need to communicate with each other, which improves network security, reduces broadcast traffic, and mitigates broadcast storms.

Configuring Inter-VLAN Communication

After VLANs are assigned, users in different VLANs cannot directly communicate with each other. If users in different VLANs need to communicate, configure VLANIF interfaces to implement inter-VLAN Layer 3 connectivity.

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

After VLANs are assigned, users in the same VLAN can directly communicate with each other. If some users in the same VLAN need to be isolated, configure MQC-based intra-VLAN Layer 2 isolation.


Intra-VLAN isolation can also be implemented using port isolation. For details about port isolation, see Configuring Interface Isolation in Huawei AR Series IOT Gateway Configuration Guide - Interface Management.

Configuring a Traffic Policy to Implement Inter-VLAN Layer 3 Isolation

After VLANIF interfaces are configured to implement inter-VLAN connectivity, users in different VLANs can communicate at Layer 3. If some users in different VLANs require unidirectional communication or need to be isolated, configure a traffic policy.

Configuring an mVLAN

To use the NMS to manage devices in a centralized manner, assign VLANs and configure a VLAN as the management VLAN.
