Please advise how to troubleshooting and fix the incorrect operational speed of the network port e0d. This is a switchless with the offical cables, and it should operate as 10000 Mbps but it operates it as 100Mbps
This is defintely an interesting problem. You may want to try upgrading to the GA release of 8.3 that went live today. Even if you were not having issues with the port I would recommend the move to GA from a RC.
If that does not work you may have a hardware problem and NetApp support would be your best bet there.
