Connection
A straight-through cable can connect devices at different network layers in the following
scenarios:
l
Connect a switch or hub to an industrial switching router.
l
Connect a computer (server or workstation) to a switch or hub.
l
Connect a switch to an upper-layer switch through an uplink interface.
A crossover cable can connect devices at the same network layer in the following scenarios:
l
Connect a computer to an industrial switching router.
l
Connect two switches at the same layer.
l
Connect two hubs.
l
Connect two computers.
l
Connect two industrial switching routers.
l
Connect an Ethernet interface of an ADSL modem to the network interface of a
computer.
NOTE
Most network devices support auto-negotiation on their interfaces. After auto-negotiation is enabled, the
local and remote interfaces can automatically negotiate about communication parameters. In this case,
the two interfaces can be connected by either a straight-through cable or a crossover cable.
