Wi-Fi device IE-WL-VL-AP-BR-CL  Web Console Configuration

NOTE 
The WLAN certificate will remain after the IE-WL-VL-AP-BR-CL reboots. Even though it is expired, it can still 
be seen on the Current Certificate. 
Advanced Setup 
Several advanced functions are available to increase the functionality of your IE-WL-VL-AP-BR-CL 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 
IE-WL-VL-AP-BR-CL 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 IE-WL-VL-AP-BR-CL 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.
