[Tfug] duplicate ip address (off topic)

[Tyler Kilian]

The MAC table is separate from the ARP table.  You wouldn't DoS a MAC
table with an IP address conflict, you'd DoS it by filling up the MAC
table with MACs, at which point the switch does usually default to either
broadcast or to crash. ;)  In the case of an IP conflict, however, there
is a 1:1 mapping of MAC to IP, so the table won't be more full by having x
number of machines competing for the same IP.
