Configuring VLANs
VLANs are key to helping enterprises improve network traffic flow, increase load, and deliver
varying levels of service and access to different groups of users. For example, Figure 75 shows how
Acme Works uses two VLANs: one for normal corporate traffic and one for Finance Department
traffic. When a Finance Department user logs in to the network, the Finance group tag is passed to
the Airgo AP, and the Finance service profile, including Finance VLAN, is applied to the user.
Database transaction traffic, which was previously a burden on the overall network, is now handled
through the Finance VLAN and is transparent to normal corporate users.
Figure 75: Example Use of VLANs to Manage Enterprise Traffic
The Airgo AP supports up to 16 VLANs including the default VLAN. Use the VLAN
Configuration panel, accessible from the Networking Services menu, to add new VLANs and map
VLANs to specific AP interfaces (“VLAN Table” on page 112). The VLAN panel contains a list of
users assigned to user VLANs; to make user VLAN assignments, use service profiles (“SSIDs and
Service Profiles” on page 84).
The VLAN Configuration panel contains the following tabs:
• VLAN Table — View the list of currently defined VLANs and add or modify VLANs.
• Interface VLAN—Assign VLANs for untagged frames arriving at the AP.
• User VLAN — View the list of client stations assigned to each VLAN by virtue of user group
membership.
• VLAN Stats — View packet statistics for each VLAN.
