VLANs are software-based and not defined by physical attributes. As a result, VLANs have an unlimited number of ports and can be created per unit, per

device, per stack, or any other logical connection combination.

VLANs function at Layer 2. Since VLANs isolate traffic within the VLAN, a Layer 3 functioning router is needed to allow traffic to flow between VLANs. Layer 3

routers identify segments and coordinate with VLANs. VLANs are broadcast and multicast domains. Broadcast and multicast traffic is only transmitted in the

VLAN where the traffic is generated.

VLAN tagging provides a method for transferring VLAN information between VLAN groups. VLAN tagging attaches a four byte tag to packet headers. The VLAN

tag indicates to which VLAN the packet belongs. VLAN tags are attached to the packet by either the end station or by the network device. VLAN tags also

contain VLAN network priority information. Combining VLANs and GVRP allows network managers to automatically disperse VLAN information.To display the
