Hi, In z/VM 5.3, we broke the native VLAN out from the default VLAN. So you can set a default and a native vlan id. DEFINE VSWITCH name RDEV rdev VLAN this_is_the_default NATIVE this_is_the_native. In z/VM 5.2, the native and the default vlan are the same. So DEFINE VSWITCH name RDEV rdev VLAN this_is_both_default_and_native.
I hope that information helps you.

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?
