When I implemented the "port isolation" rule I posted earlier. I logged the traffic first to make sure I was not blocking anything I didn't intend. The only traffic I saw was broadcast based; EGMP, UBNT Discovery, CDP, etc. This doesn't rule out the switching function of a bridge since this traffic isn't destined for a known host MAC. It doesn't prove it either because there probably wasn't any real port-to-port host-to-host traffic on that router at that time.
I would love to know that a bridge is the same as a hardware switch but just in software and thus manageable by ROS. -Ty On Wed, Feb 5, 2014 at 11:04 AM, Bill Prince < [email protected]> wrote: > Google is your friend.
