Creating virtual switch in VMware

We are trying to add a network using vsphere client for VMkernel port while creating a virtual switch. But it prompts us a red cross between the physical adapter and VMkernel port. We did test all the network cables and the network adapters. We tried creating virtual switch for service console but no gains.

• What hardware are you using for your NICs? Is it on the vSphere compatibility list? If not, vSphere may not be able to use an appropriate driver that would enable it to use VLANs and other features of a vSwitch.

• We have used NIC's which are VMware certified. I have even tried to update bios to check the hardware compatibility but didn't work.

  Chopper3 : Any chance of you answering my questions and maybe showing a screen grab of the issue?

• Did you check if your link is currently working, try verifying it connectivity by other means.
