Update 13th June
VMware have informed me that this is an error in the documentation and there's no dependency on a specific IP address (10.1.0.200) for vmk0.
There also seems to be some confusion over the need for a private switch as part of this solution.
If I receive further information I'll update.
In my case, I used 5-port mini switch to connect management ESXi host and vCF Management Switch(I used Quanta Mgmt Switch). It was work well.
I do not know exactly how it works, but it is important that Port 48 and Mgmt Port of the vCF management switch(Quanta Mgmt Switch) are connected to the private switch.
If either is not connected, the Imaging operation will be failed. I think each port seems to be used for another purpose.
I hope this information helpful.
VMware have educated me this is a blunder in the documentation and there's no reliance on a particular IP address (10.1.0.200) for vmk0. There additionally is by all accounts some disarray over the requirement for a private switch as a feature of this arrangement. On the off chance that I get additional data I'll refresh.
