Think of a vswitch a bridge between between a guest LAN and your physical LAN. You take the subnet you have on VM and use a vswitch to extend that subnet to the physical world. Within a layer 3 switch there is a router, or you have physical routers plugged into a layer 2 switch; it doesn't matter which. The point is that the routing occurs outboard and is something your networking people can set up. Just tell them to create a new VLAN and/or subnet for you that matches the subnet of your virtual network. > Also, as I mentioned in my original posting, this OSA is > also set up for SNA traffic. Is there any problem with > an OSA being used for SNA and also virtual switch? Yes, that's a problem since it requires the OSA to operate in OSE (non-QDIO) mode. You need another chpid. If you can't get it, then your only choice is to use a virtual router (guest). Alan Altmark z/VM Development IBM Endicott
