RE: Dell 4064F and Copper SFP (100BASE-T) - Link Status no detected
The transceiver shows to be Dell qualified, but is it a Dell transceiver? or 3rd party? If you shutdown the interface and then bring it back up, does the status update? The latest firmware is 126.96.36.199, and includes several overall improvements, including some SFP improvements. I am interested to see if it helps at all with this behavior.
