Slot: Optical Module Speed Mismatches NIC Speed (Major, Port
Possible Causes The optical module is faulty. The optical module speed does not match the speeds supported by the NIC.
Examples include ports being manually shut down, mismatched port speed and duplex mode, or FEC being disabled or misconfigured on high-speed modules above 100G. These issues can be diagnosed by accessing the CLI and using commands to check the configuration. S...
