5.2.6.10 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.

Lists the numerical identifier defined for the Bridge VLAN when it was initially created.
The available range is from 1 - 4095. This value cannot be modified during the edit
process.
Lists a description of the VLAN assigned when it was created or modified. The
description should be unique to the VLAN's specific configuration and help differentiate
it from other VLANs with similar configurations.
