Auto-Negotiation Best Practices

Using auto-negotiation to your advantage is as easy as remembering one simple rule:

Make sure that both sides of the link are configured the same way.

If one side of the link is set to auto-negotiation, make sure the other side is also set to auto-negotiation. If one side is set to 100/full, make sure the other side is also set to 100/full.

Tip

Be careful about using 10/full, as full duplex is not supported on all 10Base-T Ethernet devices.

Gigabit Ethernet uses a substantially more robust auto-negotiation mechanism than the one described in this chapter. Gigabit Ethernet should thus always be set to auto-negotiation, unless there is a compelling reason not to do so (such as an interface that will not properly negotiate). Even then, this should be considered a temporary workaround until the misbehaving part can be replaced.
