Profile Network Configuration
A Virtual LAN (VLAN) is separately administrated virtual network within the same physical managed network. VLANs
are broadcast domains to allow control of broadcast, multicast, unicast and unknown unicast within a Layer 2 device.
For example, say several computers are used into conference room X and some into conference Y. The systems in
conference room X can communicate with one another, but not with the systems in conference room Y. The creation
of a VLAN enables the systems in conference rooms X and Y to communicate with one another even though they are
on separate physical subnets. The systems in conference rooms X and Y are managed by the same single device, but
ignore the systems that aren't using same VLAN ID.
Administrators often need to route traffic to interoperate between different VLANs. Bridging VLANs are only for
non-routable traffic, like tagged VLAN frames destined to some other device which will untag it. When a data frame
is received on a port, the VLAN bridge determines the associated VLAN based on the port of reception. Using
forwarding database information, the Bridge VLAN forwards the data frame on the appropriate port(s). VLAN's are
useful to set separate networks to isolate some computers from others, without actually having to have separate
cabling and Ethernet switches. Another common use is to put specialized devices like VoIP Phones on a separate
network for easier configuration, administration, security, or quality of service.
To define a bridge VLAN configuration:
1. Select the Configuration tab from the Web UI.
2. Select Devices.
3. Select System Profile from the options on left-hand side of the UI.
4. Expand the Network menu and select Bridge VLAN.
