do a cp q vswitch details from tcpmaint. Determine: 1. is the linux machine in the list with an ip address? 2. determine the name of the current vswitch controller. From TCPMAINT: NETSTAT ARP ALL TCPIP <name of current controller> The netstat arp command may need to be issued twice. Does the linux machine show the mac of the OSA along with its IP address?

To answer your question, I am now able to ping the TCPIP stack address (after making the change you recommended). I am still unable to ping the gateway, however. I suppose I'll go back to beating my head against the wall...

Only a guest that needs access to multiple VLANs on the VSWITCH need be granted PORTTYPE TRUNK (VLAN-aware). The others shouldo remain VLAN-unaware (PORTTYPE ACCESS).

The ony thing that comes to mind is that the IP address/subnet/gateway on the guests doesn't match what's in the switch. Can the Linux guest ping VM TCP/IP? Alan Altmark z/VM Development IBM Endicott
