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”.

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.
