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.
If the attached end-node does not have an Auto mode setting, then you
2.
must manually configure the switch port to the same setting as the end-
node port. See Chapter 9, "Optimizing Traffic Flow with Port Controls,
Port Trunking, and Port-Based Priority".

Ping and Link Tests

The Ping test and the Link test are point-to-point tests between your switch
and another IEEE 802.3-compliant device on your network. These tests can
tell you whether the switch is communicating properly with another device.
