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.
