This KB intends to explain why the physically plugged in transceivers are not shown in 'show chassis hardware' output and where to see them
On NFX devices, the physical transceivers are not detected in 'show chassis hardware' output, which is expected.
To get this information, we have another command that can be used - show system inventory hardware optics
Sample output:
root> show system inventory hardware optics
Port information:
Serial Xcvr vendor
Port Cable type number Xcvr vendor part number
