Virtual LAN (VLAN) is a group of devices on one or more LANs that are configured so that they

can communicate as if they were attached to the same LAN, when in fact they are located on a

number of different LAN segments. Because VLANs are based on logical instead of physical

connections, it is very flexible for user/host management, bandwidth allocation and resource

optimization. There are two types of VLAN as follows:

Port-Based VLAN: Each physical switch port is configured with an access list specifying

membership in a set of VLANs.

ATM VLAN: Using LAN Emulation (LANE) protocol to map Ethernet packets into ATM cells and

deliver them to their destination by converting an Ethernet MAC address into an ATM address.

PVID:

Each physical port has a default VID called PVID (Port VID). PVID is assigned to

untagged frames or priority tagged frames (frames with null (0) VID) received on this port.
