can communicate as if they were attached to the same wire, 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.
