The following figure gives an illustration of how the Spanning Tree

Algorithm assigns bridging device ports.

Virtual LANs

Switches do not inherently support broadcast domains, which can

lead to broadcast storms in large networks that handle a lot of IPX or

NetBeui traffic. In conventional networks with routers, broadcast

traffic is split up into physically separate domains to confine broadcast

traffic to the originating group and provide a much cleaner network

environment. This switch creates segregated broadcast domains based

on easily configurable VLANs, these are then linked, as required, via a

router or Layer 3 switch.

An IEEE 802.1Q VLAN is a group of ports that can be located

anywhere in the network, but communicate as though they belong to

the same physical segment. VLANs help to simplify network

management by allowing you to move devices to a new VLAN

without having to change any physical connections. VLANs can be

easily organized to reflect departmental groups (such as Marketing or

R&D), usage groups (such as e-mail), or multicast groups (used for

multimedia applications such as video conferencing).

VLANs provide greater network efficiency by reducing broadcast
