X440 summit switches port showing the below log messages: <Erro:Kern.Error> bcm_custom_extr_eee_config_set(16700): eee set enable error, port=9, unit=0, enable=0, rv=-16 log messages seems associated with Hardware issue for the switch.
To confirm further on hardware issue we need to gather the below details :
Following outputs from Broadcom shell:
• ps • phy info • port <internal_portname> (from all problematic port) • phy <internal_portname> (from all problematic port)
On further debugging on these outputs if it is confirmed that the external PHY driver is not installed in hardware for all problematic ports then it would be determined as Hardware issue.
Going forward we can with this confirmation raise RMA for the concerned hardware.
