Vmkernel port

I have seen in our enviironment vmkernel port with IP address, I am not sure what is it used for. when I open the properties of the vswitch and select the port then edit, I see the page displayed below..
The iSCSI Port Binding option greyed out.

Any idea?

Thank you

VMKernel Portgroups are used to carry NFS, iSCSI, vMotion, Storage vMotion, and Fault Tolerance traffic and Management traffic.

If using iSCSI you would bind a network interface to the VMKernel Portgroup.

You can see that in my EE Article

HOW TO: Add an iSCSI Software Adaptor and Create an iSCSI Multipath Network in VMware vSphere Hypervisor ESXi 5.0

So in your example, it may not be used for iSCSI, but could for NFS as vMotion, Storage vMotion and FT are not selected.

I do not think the Vmkernel port is used for anything, since the Vswitch it is on has no physical Nic, as shown in the screenshot:

No physical network interface on vSwitch, then it will no pass any traffic.

so not in use.
