1. Ask yourself and your colleagues "what changed?" 2. Look at the TCPIP console and see if you have any errors. 3. Issue "ifconfig -a" and see if everything you expect to be UP is up. 4. QUERY VSWITCH to see if they are in the state you expect. 5. At some point in the past you drew a picture of the network into which you placed VM TCP/IP. Confirm with your network architects that the picture is still correct (subnet masks & routers). Alan Altmark z/VM Development IBM Endicott
