Looking at the actual forwarding databases, we're running one MAC per port on all but the trunks - we're *very* diligent about preventing non-PAIX layer 2 devices from contaminating our layer 2 fabric. Given that, I think you're suffering from GSR's not being able to do MAC accounting (as Leo suggested) rather than there being any "layer 2 noise" in the switch fabric. The PAIX engineering folks (send mail to <[email protected]>) would be happy to take any follow-up questions you might have about PAIX infrastructure. Stephen
