Hi Denny, Since I didn't see any other responses to you, I'll respond with my newly gained perspective on VLAN-aware VSWITCHs. You may want to read my thread "VSWITCH VLAN-aware not connecting" starting in May 2008, and continuing into June. I think the definitions you've given us look correct, based on what I know. But as you see from the other thread, my connections still aren't working either. I wonder if you are experiencing the same thing I am.
Do this. Take some VM TRSOURCE traces. Here's the commands I'm using: trso id trc1 type lan owner system lanname vsw20x vlan 304 (define the trace) trso disp (just to see that it is there) trso en id trc1 (enable the trace) Do a simple PING from your PC trso disa id trc1 ("stop" the trace) Then, the trace records should be in a TRF file in the spool. q trf * (to get the spoolid number) tracered -spoolid- cms trc1 trace (all Then, acc 592 t (TCPAMAINTs 592 disk) ipformat trc1 trace Look at the records in the IPFORMAT trace. Mine show that the "ping" (i.e. an ECHO) are actually coming from my PC into VM, into my Linux guest, and the ECHO REPLY is coming all the way back out. But, similar to you, it's not getting out to the real network switch somehow. IBM hasn't been able to tell me why it's not getting out, yet. Cleanup: trso drop id trc1 q trf * I'll be eager to hear of your progress.

I will put the trunk in place on core switch 2 tonight. I will trunk VLANs 390, 391, 393 and 389(new vlan for this project). I will use a native vlan of 499. Will that work for you?" I tentatively told him I thought it was OK, but I have not found a way to successfully configure the NATIVE VLAN (I *think* that's the problem). It appears there is a way to do this with the NATIVE option on the DEF VSWITCH command on z/VM 5.3, but I am at 5.2. If I issue the following: DEF VSWITCH VSW1 RDEV 9160 VLAN 499 SET VSWITCH VSW1 GRANT TCPIP VLAN 389 That combination allows me to ping the gateway on his switch, but I can go no further out. I cannot get to my TCPIP stack from outside the network either, as I expected. I have tried several permutations of VLAN identifiers on the DEF VSWITCH command, and the only way to reach the gateway is to use VLAN 499 or VLAN 1. I have left VLAN 389 on the SET VSWITCH VSW1 GRANT command for TCPIP for each attempt, as they requested the hosts go on VLAN 389. Before I go back to the network guys, does anyone know of a way to accommodate (on 5.2) the NATIVE VLAN configuration the network guy specified above?
