Hello,
I am running a ESXi 5.0 host with Intel 82599EB 10G NICs which are part of a Distributed Switch and when I go to Managed Physical Adapters I do not have the option to set the Configured Speed, Duplex option to Auto-Negotiate for this adapter. The only selection available is 10000MB, Full Duplex. My 1000MB adapters I am able to select Auto-Negotiate. I am curious as to why this is.
Any details on this is greatly appreciated.
