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. Interfaces on most devices can dynamically
adapt to straight-through cables and crossover cables. For interfaces that cannot dynamically
adapt to either type of cable, connect interfaces at the same layer using the crossover cables
and interfaces at different layers using the straight-through cables.
