Example of VLAN connections
Full-duplex operation only applies to point-to-point access (such as when a
switch is attached to a workstation, server, or another switch). When the
switch is connected to a hub, both devices must operate in half-duplex mode.
Avoid using flow control on a port connected to a hub unless it is actually
required to solve a problem. Otherwise, back pressure jamming signals may
degrade overall performance for the segment attached to the hub.
