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.

Description
could continue affect the system in terms of response time. This
setting should be used with caution.
• OFF - Turning this parameter OFF will disable FAST LINK
DETECTION completely. The switch will need a longer time to
detect a link failure. This will result in a longer network recovery
time of up to 2s.
Synopsis: 100 ms to 1000 ms
Default: 100 ms
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).
