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 109 .
Figure 109 A VLAN diagram
You can implement VLANs based on a variety of criteria. The web interface, however, is available only
for port-based VLANs, which group VLAN members by port. A port forwards traffic for a VLAN only after
it is assigned to the VLAN.
For more information about VLAN, see H3C WX Series Access Controllers Layer 2 Configuration Guide.
