I hope you don't mind me asking a real world question here, I think the content is plenty relevant to the studies at hand.
I have ARP watch running on my network and I am regularly seeing a flip flop occur from one of the hosts in a fairly new VLAN. Two 4506's have an interface in this VLAN with HSRP running between them. The host IP keeps flipping between the MAC of the laptop, and the MAC of the standby switch. This doesn't happen rapidly, but maybe a few times a day. To me this implies that the secondary switch is occasionally answering ARP query's for the host's IP address. Can anyone give an explanation or a theory of why the switch would do that?
