Hi Simon,
I have noticed that in some cases after the upgrade you will need to follow the below proces, which I just added to my original post:
- Remove the original VXLAN configuration.
- Restart the vCNS web service (Exact commands were listed in my post vCloud Networking & Security 5.1.1 create dvPort Groups, but fails to create vmknic interfaces)
- Re-Add vCenter to vCNS
- Add the VXLAN Configuration again.
This seems for me to fix the problem in my lab and at a couple of customers.
Good luck!
