I am not sure if there is a command for this, but I have sent this over to our TAC engagement team and they will be reaching out to you shortly to gather some more information regarding your configuration so we can get you in touch with the correct group . I encourage you to continue to post in the community and let me know if there is any way I can help. Once your post is resolved, we will make sure to post the resolution back to the community to help other members.

State changes of a port can be found in the output of the command "fabriclog -s"
Actual activity through "portlogdumpport" althoug the data is only available for the last couple of minutes
If you need the data for a very long time or across firmware updates you need to store the output somewhere else outside of the switch.
