The switch can provide the same bandwidth of FDDI and ATM at much lower costs.
In addition, all current adapters and network devices can still be used. The
switching cross-domain connection is better than bridge and router because users
can retain LAN structure in which any node can freely communicate with any other
node.

IEEE 802.1Q VLAN Application
The switch supports up to 4096 Group ID, IEEE 802.1Q-compatible virtual LAN
(VLANs).
Port-based VLAN Workgroup12s
You can group the switch ports into broadcast domains by assigning them to the
same VLAN to increase network capacity and performance. With network
segmentation, each switch port connects to a segment that is a single broadcast
domain. Packets received in one VLAN can only be forwarded within that VLAN.
VLAN allows the grouping of end stations logically, based not on physical location
but on business policies such as job function or department. Members of a group
can be dispersed throughout a facility - they do not have to be connected in close
physical locations.
