No I think I have the terminology correct. I run multiple virtual VLANs accessed via redundant zVM VSWITCHs connected to redundant Cisco 3550 trunk ports using HSRP. Each host within a VLAN has its own VLAN interface associated via eth0 with the VSWITCH virtual devices and the Cisco 3550 contains multiple vlan interfaces for default gateways. This allows me to separate production, test, development, whatever servers and services into their own broadcast domains. At least that works with SLES8. I have had some trouble cloning SLES9 from a guest lan master. I hope to get back to working with the SLES9 and I thought I would get the list thoughts. Thanks, Al Schilla State of Minnesota

VLAN is the technique to tag packets with a VLAN ID. Systems will only see traffic that matches their own VLAN ID, so it allows you to create virtual networks on a single physical network. The z/VM VSWITCH allows you to have the trunk connection (that carries traffic from multiple VLANs) into z/VM and have CP do some of the work that others do in their outboard switch. The VSWITCH really is a Guest LAN with an extra. The virtual NIC coupled to the VWITCH looks very much like one coupled to the Guest LAN.
