Hello, Caleb! Layer 2 different from Layer 3 that each system which share OSA Adapter must have it's own MAC address, different from real MAC of OSA device. z/VM VSWITCH technology generates this MAC automatically. It's very useful. When you don't use VSWITCH and directly attach OSA device (in a native LPAR it's the only option) you need to specify some MAC address for your network interface card, so it can listen for a packets.
You can share one OSA Adapter between two systems and use different Layers for their networking, but they cannot communicate with each other, so be careful with that. Just ping me in the sametime if you will have more questions. -- With best regards, Andrew ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
