I checked the port configuration for the trunk and it says that trk1 is member of default vlan and my vlan ohoh.
I also checked the physical connection for the 3 esx hosts to my 3 trunked ports on the switch and they
are 100% correct connected.
Trunk should be 802.1q as i want to have multiple vlans on this 3 esx-nics connected to the 3 switch ports.
As configuration on switch side seems very simple my suggestion was that there is an error on esx-nic-side?
But here i revered to the vmware guides and tested several settings.
There must be a little mess that keeps everything from working...
