Bridge VLAN
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 in conference room X and some in 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). VLANs 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.
