Make sure your VNICs remain ACCESS (not trunk) with the correct VLAN/subnet and zLinux will see no difference.
VSWITCH will sort out the trunking on behalf of the zLinux guest. If you need to communicate between zLinux instances in different VLANs/subnets IP traffic will need to be routed instead of going directly on the VSWITCH.

(CMS/CTR) (CTR) Sent: 24 March 2011 17:01 To: IBMVM@LISTSERV.UARK.EDU Subject: Supporting Dot.1q trunk in z/Linux Hi We have run out of the IPs on a certain SUBNET. The network folks say we need to set the VSWITCHES up as a Dot.1q trunk on both their side and the z/Linux side. We are not currently using Dot.1q trunk. So my question is from my z/Linux side what changes to I need to make and where are these changes reflected In my setup on the z/Linux. Just so you know my z/VM TCP/IP stack is not really being used for the z/Linux guests that is being done within z/Linux in my case RHEL 5.2 Thanks for the help!
