One requirement with building proxy guests for GDPS/xDR is that you do not use virtual switches (since everything gets quiesed during a hyperswap). So in order to setup DEDICATED OSA adapters I think I'm forced to use VLAN tagging in LINUX. They also recommend using bonding. Which goes back to my original question. When I clone a guest I'm coming up on a VSWITCH connected via eth0, on VLAN 14.
So I putty in at that point and try to configure ifcfg-eth1 and ifcfg-eth2, then ifcfg-bond0, then ifcfg-vlan10. The free IP addresses I have are on VLAN10. I found something on the net about loading a module (8021q) so I did that and rebooted, when it comes up I'm getting the following Mar 7 14:44:29 lxqmq001 kernel: 8021q: adding VLAN 0 to HW filter on device eth0 Mar 7 14:44:29 lxqmq001 kernel: eth0: no IPv6 routers present Mar 7 14:44:29 lxqmq001 kernel: bonding: Ethernet Channel Bonding Driver: v3.7.1 (April 27, 2011) Mar 7 14:44:29 lxqmq001 kernel: bonding: bond0 is being created...

I am unable to ping the 193.91.10.113 address from another server. I tried changing /etc/sysconfig/network/routes from this: default 205.145.91.254 - - to this: default 193.91.10.254 - - But I lose my connection on eth0 as well as the new vlan10 bonded address. -----Original Message----- From: Linux on 390 Port [mailto:LINUX-390@VM.MARIST.EDU] On Behalf Of Alan Altmark Sent: Tuesday, March 07, 2017 1:37 PM To: LINUX-390@VM.MARIST.EDU Subject: Re: DEDICATED OSA, LINUX VLAN tagging and bonding On Tuesday, 03/07/2017 at 06:18 GMT, "Vitale, Joseph" <joseph.vit...@bnymellon.com> wrote: > Hello, > > Interested to know if VLAN Tagging can be done via zLinux if zVM currently adding VLAN Tag.

If you do that, you can use vconfig on Linux to let it do the tagging (eeewwww!) Alternatively, you can use a PORTBASED VSWITCH and assign a VLAN to a virtual NIC, so that Linux can remain VLAN unaware. In this mode, you: a) Add the PORTBASED option to DEFINE VSWITCH b) Use the SET VSWITCH PORTNUMBER command to assign guests to a port number. c) Use the SET VSWITCH VLANID command to assign a port number to a VLAN d) Remove the VSWITCH name from the NICDEF in the directory e) Add COMMAND COUPLE to the directory to connect a vdev to a port. Folks at SHARE in San Jose this week can see my presentation on this Wednesday, along with a preview of the PORTBASED/USERBASED VSWITCH unification and simplification that will be coming soon to a z/VM system near you.
