Port Auto-Negotiation

When a link LED does not light (indicating loss of link between two devices),
the most common reason is a failure of port auto-negotiation between the
connecting ports. If a link LED fails to light when you connect the switch to a
port on another device, do the following:
1. Ensure that the switch port and the port on the attached end-node are
both set to Auto mode.
2. If the attached end-node does not have an Auto mode setting, then you
must manually configure the switch port to the same setting as the end-
node port. Refer to Chapter 10, "Port Status and Basic Configuration".
