NOTE
Straight-Through and Crossover Cables
Ethernet cables are classified into straight-through and crossover cables according to the
wiring scheme used at the two ends of the cables. The interfaces of most devices can
dynamically adapt to straight-through cables and crossover cables. For interfaces that cannot
dynamically adapt to the two types of cables, connect interfaces at the same layer using the
crossover cables and interfaces at different layers using the straight-through cables.
