Greetings,
I saw this post and would like to get some verification on running both layer 2 and layer 3 on the same OSA. So we can now have say a z/VM running Linux guest on a layer 2 to an OSA along with a layer 3 TCP stack on the same z/VM using the same OSA? Would we be able to also have other LPARS either z/VM or z/OS share this same OSA with layer 3 as well ? >From my understanding you had to have OSPF to share the OSA’s with other LPARS >( mainly with the z/OS ) We currently have the new Z10 box Thanks Russell Gendreau Time Customer Service, Inc. 813-554-2064 ________________________________ From: The IBM z/VM Operating System [mailto:[email protected]] On Behalf Of Anson Sent: Monday, September 21, 2009 8:28 PM To: [email protected] Subject: 回复： Does OSA Express2 Ethernet support zVM layer2 Ronald, Thanks for your information! I checked our z900's configuration. It should be OSA Express in stead of Express2. There is one thing I couldn't understand. The z/OS on another LPAR can work well on ipv6. They used the same OSA adapter.

But what won't work on a z900, is sharing the osa with layer 2 and layer 3 traffic. As I recall, the first to connect to the OSA could set the mode (2 or 3) and all other shared connections have to use the same mode (just like the portname). The restriction got lifted with z990, there you can use the same shared OSA, mixing layer 2 and layer 3 connections.
