Hello Jon,
As for #2, thats kinda where I was going with my original question -- why would a switch that is processing a session between two endpoints suddently forget the MAC? Yes, there are timeouts in play here, but aren't those along the lines of several minutes?
I'm no switch expert, but your last comment caused an hypothesis to pop into mind. Do any of your hosts have hard-coded MAC addresses set up? This isn't common, but if you're trying to prevent ARP poisoning, one might do this. If you were to do this, and not tell the switch which ports had those MACs, then it wouldn't get a chance to learn those MACs since those hosts wouldn't bother sending ARP requests, right? Just a thought. ------------------------------------------------------------------------ This List Sponsored by: Cenzic Need to secure your web apps? Cenzic Hailstorm finds vulnerabilities fast.
