Virtual LANs

This switch supports the following VLAN features:

•Up to 256 VLANs can be configured based on the IEEE 802.1Q standard

•Distributed VLAN learning across multiple switches using explicit or implicit tagging and GVRP protocol

•Port overlapping, allowing a port to participate in multiple VLANs

•End stations can belong to multiple VLANs

•Passing traffic between VLAN-aware and VLAN-unaware devices

•Priority tagging

•Port trunking with VLANs

Assigning Ports to VLANs

Before enabling VLANs for the switch, you must first assign each port to the VLAN group(s) it will participate in. (By default all ports are assigned to VLAN 1 as untagged ports.) Add a port as a tagged port (that is, a port attached to a VLAN-aware device) if you want it to carry traffic for one or more VLANs and the device at the other end of the link also supports VLANs. Then assign the port at the other end of the link to the same VLAN(s). However, if you want a port on this switch to participate in one or more VLANs, but the device at the other end of the link does not support VLANs, then you must add this port as an untagged port (that is, a port attached to a VLAN-unaware device).

Port-based VLANs are tied to specific ports. The switch’s forwarding decision is based on the destination MAC address and its associated port. Therefore, to make valid forwarding and flooding decisions, the switch learns the relationship of the MAC address to its related port—and thus to the VLAN—at run-time. When the switch receives a frame, it assigns the frame to the port’s default VLAN if the frame is untagged (determined by the PVID of the receiving port), or maps it for output to the broadcast domain associated with the frame’s VLAN tag.

Port Overlapping

Port overlapping can be used to allow access to commonly shared network resources among different VLAN groups, such as file servers or printers. Note that if you implement VLANs which do not overlap, but still need to communicate, you can connect them using a router or Layer 3 switch.

Automatic VLAN Registration (GVRP)

GVRP defines a system whereby the switch can automatically learn the VLANs each endstation should be assigned to. If an endstation (or its network adapter) supports the IEEE 802.1Q VLAN protocol, it can be configured to broadcast a message to your network indicating the VLAN groups it wants to join. When this switch receives these messages, it will automatically place the receiving port in the specified VLANs, and then forward the message to all other ports. When the message arrives at another switch that supports GVRP, it will also place the receiving port in the specified VLANs, and pass the message on to all other ports. VLAN requirements are propagated in this way throughout the network.
