VLAN Workgroups and Traffic Management

The AP assigns clients to a VLAN based on a Network Name (SSID). The AP can support up to 9 SSIDs per radio

interface, with a unique VLAN configurable per SSID.

The AP matches packets transmitted or received to a network name with the associated VLAN. Traffic received

by a VLAN is only sent on the wireless interface associated with that same VLAN. This eliminates unnecessary

traffic on the wireless LAN, conserving bandwidth and maximizing throughput.

In addition to enhancing wireless traffic management, the VLAN-capable AP supports easy assignment of

wireless users to workgroups. In a typical scenario, each user VLAN represents a department workgroup; for

example, one VLAN could be used for a marketing department and the other for a human resource department.

In this scenario, the AP would assign every packet it accepted to a VLAN. Each packet would then be identified

as marketing or human resource, depending on which wireless client received it. The AP would insert VLAN

headers or "tags" with identifiers into the packets transmitted on the wired backbone to a network switch.

Finally, the switch would be configured to route

packets from the marketing department to the

appropriate corporate resources such as printers and

servers. Packets from the human resource

department could be restricted to a gateway that

allowed access to only the Internet. A member of the

human resource department could send and receive

e-mail and access the Internet, but would be

prevented from accessing servers or hosts on the

local corporate network.
