The following diagram shows the layout of interfaces on the rear panel of the 5200.
The current link status is displayed on the right side of the page: Up means all are up and
Down means all are down. If the status is mixed, the first status listed is the managed/
protected interface, and the second status listed is E1/E2.
Creating a VLAN on the Protected Side (Optional)
You can create one or more virtual LANs on the protected side of your network. A VLAN
is a logical grouping of nodes within a LAN. The nodes in a VLAN do not have to be
physically connected to the same switch or hub to communicate with each other.
You might want to create VLANs on the protected side of your network to define different
groups of enterprise hosts and resources to which to route traffic from BSC users based on
their assigned role. For example, if you create a "guest" role, you might want to route
guest traffic away from the enterprise network backbone to a lower bandwidth Internet
connection. You could accomplish this by creating a VLAN on the protected side of your
network and then tagging all data from users assigned the role of "guest" with that
protected-side VLAN ID.
See "Defining a Role" on page 8-4 for more information about tagging user data based
on the user's assigned role. See Appendix A, "An Overview of Virtual LANs," for more
information about the use of VLANs on Bluesocket BSC networks.

BSC until you have completely finished configuring the BSC for use in your network.

Top/Down – The protected physical port and the E2 interface are one trunk. The
managed physical port and the E1 interface are one trunk. This logically groups
the ports together on the same NIC.
Crisscross - The protected physical port and the E1 interface are one trunk. The
managed physical port and the E2 interface are one trunk. This puts the second
interface on a different NIC, protecting against NIC failure – if the NIC fails, then
protected and managed interfaces continue to work
