I have a few 3560 switches and if I log into them via a console cable and type show arp, I only get the switches IP and one other system that pings everything on the network to verify it is up. All the other ports with systems connected and working do not show up. I thought as soon as you plugged a system into a port the switch should cache that info for a while to decreased broadcasts? Something else I can do to get that working? On a side note, if I ping the switch itself from my system, my IP will show up, but that is all.
