Activity on a link; no faults.
The LED will blink green even when there is very little control traffic.

Link is off due to a fault or because it has exceeded a limit set in the switch software.
Caution Link faults occur when noncompliant cabling is connected to an SFP/SFP+
port. Use only standard-compliant cabling to connect to Cisco SFP/SFP+ ports.
You must remove from the network any cable or device that causes a link fault.
