When a Front panel port is disabled or the port mode is mismatched, it can cause incorrect register reads. This may manifest as port interface flapping on other unrelated ports.
The status on other interfaces may incorrectly show ‘down’ when the interface is ‘up’ or other unexpected behavior.
Front Panel Port is disabled or a port mode mismatch, such as a 100GE optic installed when the port is configured for 40GE operating mode.
Enable all Front Panel ports, even those not in use, and ensure there are no port mode mismatches.
