Configuring VLANs

• Add/remove member ports to/from a VLAN.
• Create or delete VLAN interfaces.
• Configure VLAN interface parameters.
Overview
Ethernet is a network technology based on the CSMA/CD mechanism. As the medium is shared,
collisions and excessive broadcasts are common on Ethernet networks. 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.
For hosts of different VLANs to communicate, you must use a router or Layer 3 switch to perform
Layer 3 forwarding. To achieve this, VLAN interfaces are used. VLAN interfaces are virtual interfaces
used for Layer 3 communication between different VLANs. They do not exist as physical entities on
devices. For each VLAN, you can create one VLAN interface. You can configure VLAN interfaces to
forward traffic at the network layer.
