The way i want is using multiple vlans/portgroups with different vlan id on the trunk of 3 hosts (each with 1 nic connected to the dvswitch where
the portgroups were configured).
On the hp switch i created a trunk with the 3 esx-nic-ports and set the port mode for each port to trunk.
This alone does not work.
Therefore i tried additionaly add vlans on the hp switch with the vlan ids configured on the portgroups.
In the vlans i tried setting the trunk to tagged, untagged and no - but no option was working.
I restarted the switch after each configuration.
Any ideas?
