AirWorks AWK-3131A Web Console Configuration
Advanced Settings
Several advanced functions are available to increase the functionality of your AWK-3131A and wireless
network system. A VLAN is a collection of clients and hosts grouped together as if they were connected to
the broadcast domains in a layer 2 network. The DHCP server helps you deploy wireless clients efficiently.
Packet filters provide security mechanisms, such as firewalls, in different network layers. Moreover, the
AWK-3131A can support STP/RSTP protocol to increase reliability across the entire network, and SNMP
support can make network management easier.
Using Virtual LAN
Setting up Virtual LANs (VLANs) on your AWK series increases the efficiency of your network by dividing the
LAN into logical segments, as opposed to physical segments. In general, VLANs are easier to manage.
The Virtual LAN (VLAN) Concept
What is a VLAN?
A virtual LAN, commonly known as a VLAN, is a group of hosts with a common set of requirements that
communicate as if they were attached to the same broadcast domain, regardless of their physical location. A
VLAN has the same attributes as a physical LAN, but it allows for end stations to be grouped together even if
they are not located on the same network switch. Network reconfiguration can be done through software
instead of physically relocating devices.
VLANs now extend as far as the reach of the access point signal. Clients can be segmented into wireless
sub-networks via SSID and VLAN assignment. A Client can access the network by connecting to an AP
configured to support its assigned SSID/VLAN.
Benefits of VLANs
VLANs are used to conveniently, efficiently, and easily manage your network in the following ways:
• Manage adds, moves, and changes from a single point of contact
• Define and monitor groups
• Reduce broadcast and multicast traffic to unnecessary destinations
• Improve network performance and reduce latency
• Increase security
• Secure network restricts members to resources on their own VLAN
• Clients roam without compromising security
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.
