Tundra, Here's an answer from one of our networking experts: The main difference is that with VNICs, a high priority (dladm command) could be assigned so that all cluster interconnect traffic gets higher priority treatment. It is not clear how this can be done with the basic VLAN method. Thanks, Nick
