Hi, Tobias, While I don't know the answer to your question, let me take a stab at what I think you maybe asking. The failover for the VSWITCH if the OSA connection goes down is handled by the VSWITCH and specifically the TCPIP Controller. So whether or not the two OSAs communication with BPDU does not affect how the failover situation is determined. I'm sure if this is where you were going with your question or not but hopefully it helped.

So i took the Redpaper REDP-3719-00 "VSWITCH and VLAN Features of z/VM 4.4" and started reading and testing. But in the "High-Availability" chapter there is following note: -- note -- Important: Only one port is used for communication between the VSWITCH and the LAN at any one time. Additional ports defined for the VSWITCH are not connected until required. This means that your backup ports can be in use on other guests, or on other VSWITCHes. -- note -- Question : I want to connect 2 OSA to my VSWITCH. Do the 2 OSA communicate via any LAYER-2 protocol (e.g. BPDU)?
