VLAN configuration
Overview
Ethernet is a network technology based on the Carrier Sense Multiple Access/Collision Detect
(CSMA/CD) mechanism. As the medium is shared, collisions and excessive broadcasts are common on
an Ethernet. To address the issue, virtual LAN (VLAN) was introduced to break a LAN down into separate
VLANs. VLANs are isolated from each other at Layer 2. A VLAN is a bridging domain, and all broadcast
traffic is contained within it, as shown in Figure 91 .

You can implement VLANs based on different criteria. The Web interface is available only for port-based
VLANs. Port-based VLANs group VLAN members by port. A port forwards traffic for a VLAN only after
it is assigned to the VLAN.
NOTE:
For more information about VLAN, see H3C WA Series Access Points Layer 2 Configuration Guide.
