Hey folks,

when reading documentation i wondered about the switching loop issue on p/vswitches - lets assume:

• we got 5 VMs with each having 1 vNic which are interconnected to the same vSwitch.

• this vSwitch has connection to 2 pNics connecting to a (HP) pSwitch, with configuration route based on the originating port ID.

According to my logic (in a physical world) a connection between 2 switches creates loops, at least when one device is broadcasting, in the physical world, STP adresses this issue.

As i could not find any hint about looping frames in a vSwitch <-> pSwitch environment, could any1 explain

• why a vNic broadcast frame does not loop around the vSwitch / pSwitch?

• if it indeed does, how to adress this issue in the virtual/physical-combined world;)

Regards,

Philipp
