Configuring a VLAN
A virtual local area network (VLAN) is a logical grouping of workstations, servers, and network
devices so that they appear to be on the same LAN whether they are part of a larger local LAN or
geographically dispersed. A VLAN allows a network of computers and users to communicate in a
simulated environment as if they exist in a single LAN and are sharing a single broadcast and
multicast domain.
You can create port-based VLANs that act like a straight communication and isolating the traffic
from each other. In setups as seen in
and
the Corporate Network(s) need to
recognize port-based VLANs. The Corporate Networks in
require the ends at
Corporate Network 1 and Corporate Network 2 to be setup as either trunks or port-based VLANs
to prevent loops at either end.
shows a simple connection where each VLAN
terminates in a single device (or isolated subnet). Unlike
, there is no requirement for
additional setup of the Corporate Network as the Fiber Ethernet Switch Transceiver card appears
as a transparent cable extender.
Configuring the VLAN Feature
The Fiber Ethernet Switch Transceiver cards support port-based VLANs. The switching ports are
partitioned into virtual private domains assigned on a per port basis. This provides a simple
partitioning of the switch so that different user groups can share the switch yet be isolated from
each other.

Note
— By default, all ports are automatically assigned to VLAN 1, allowing each
card to operate as a generic ethernet switch (any port to any port). There must always
be at least one VLAN enabled for the card to function as an ethernet switch.
