Detecting Cable Faults

Parameter

Description

The time that the link has to continuously stay up before the "link up" decision is made

by the device.
(The device performs de-bouncing of Ethernet link detection to avoid multiple responses

to an occasional link bouncing event, e.g. when a cable is shaking while being plugged-

in or unplugged).

Section 3.6.11

Detecting Cable Faults

Connectivity issues can sometimes be attributed to faults in Ethernet cables. To help detect cable faults, short

circuits, open cables or cables that are too long, ROS includes a built-in cable diagnostics utility.
The following sections describe how to run diagnostics on Ethernet cables:
•

Section 3.6.11.1, “Viewing Cable Diagnostics Results”

•

Section 3.6.11.2, “Performing Cable Diagnostics”

•

Section 3.6.11.3, “Clearing Cable Diagnostics”

•

Section 3.6.11.4, “Determining the Estimated Distance To Fault (DTF)”

Section 3.6.11.1
