When the sub interface is added to a trunk vNic backed by distributed portgroup, VLAN or VXLAN trunk is automatically configured on the trunk port. When the sub interface is added to a trunk vNic backed by standard portgroup, only VLAN trunk is supported.
Verify that a sub interface with a trunk vNic backed by standard portgroup is available. See Add a Sub Interface.
