VLANs are an IEEE thing. Logon Here and Guest LANs (with attendant virtual NICs) are a VM thing.

Broadcast was added to virtual HiperSockets in z/VM v4.3, as were virtual OSA Express (QDIO) adapters. P.S. VM folk need to be REALLY CAREFUL when talking to Network folk. If you tell a network person "I've got VLANs!", they will be very confused when you can't answer the follow-up question: "What is your VLAN id?". (I can't emphasize this point enough. Trust me on this.) Or you will be confused when they ask you if VM supports VLANs. (The answer is "If you mean IEEE VLANs, no, but VM does have a virtualized LAN capability.") I wish IEEE had used the term "Logical LAN", but "LLAN" isn't so. For those who don't know, an IEEE VLAN is a way to overlay multiple logical LAN segments on a single physical segment. The switch handles the segregation. Some hosts can belong to more than one logical segment using a single physical ethernet connection. A broadcast by a member of VLAN 5, for example, is delivered only to other members of VLAN 5. Alan Altmark Sr. Software Engineer IBM z/VM Development
