Thanks for the comments. However I am not in the position to upgrade so I get vDS now and I have understood that I cannot use LACP unless I use vDS.
I read the links to articles for HP and Cisco switches but they used LACP too...
So isn't there really ANY possibility to do NIC teaming / aggregating between my ESXi 6.5 vSwitch and the HPE switches with the properties I mention in my original post?
If NOT can you suggest other switch model(s) where this feature is possible..:?
Thanks again
