Mcowger,
I'm aware of the vswitch concept from the vcp course I did late last year. If memory serves, there is a standard switch, then an extended (functionality) switch, I don't know, I'm still sketchy on the details, and haven't revisited the course materials in a while. The thing is that this bridging takes place to bridge a virtual connection ( a VM) to a host's physical connection...so far I don't have any VM's installed, just ESXi as a bare metal install.
