Alan, Can you tell me where you have the Best Practices document?
Thank You, Terry Martin Lockheed Martin CMS - CITIC 3300 Lord Baltimore Drive, Suite 200, 21244 Engineering Computing Mainframe Support Cell - 443 632-4191 -----Original Message----- From: The IBM z/VM Operating System [mailto:IBMVM@LISTSERV.UARK.EDU] On Behalf Of Alan Altmark Sent: Monday, April 04, 2011 5:03 PM To: IBMVM@LISTSERV.UARK.EDU Subject: New VSWITCH definition Best Practice It's time for me to update my Best Practice for VSWITCH definition With the changes that were made to z/VM 6.1 for zEnterprise ensembles, but which benefit non-ensemble configurations, there's a new sheriff in town. Forget "VLAN 666". Here's what you really want to see: DEFINE VSWITCH ... VLAN AWARE NATIVE NONE This does the following: 1. Sets the VSWITCH in trunk mode 2. Requires that you explicitly authorize a guest to use one or more VLAN IDs. 3. If you don't provide an authorization, outbound traffic from the guest will be discarded. 4. No untagged frames from VLAN-aware guests will be emitted by the VSWITCH. The new "VLAN AWARE" and "NATIVE NONE" are not available on z/VM 5.4. You will have to continue with the VLAN 666 trick.
