Problem #2:
This scenario is very similar to the first. We have the same problem to solve
but the logistics are simpler, in that all of the devices are local and can be wired into the same
switch.

Solution: We will use a Stride managed switch, utilizing the Port-based VLAN feature. The
question could be posed, “Why not just use two unmanaged switches?” While this would
work, the customer wants to use as few components in the system as possible to minimize
points for possible equipment faults and he would like the enhanced diagnostic capabilities
that a managed switch provides.
Switch Setup:
When using port-based VLANs, VLAN tags don’t determine which VLAN a port is in so it is
not necessary to configure the ports.
