Most likely someone on your network is trying to do an SNMP poll on that
switch with an invalid community string. Some devices will send the IP
address of the machine doing the polling in the trap, but it doesn't look
like yours does. In your case, it sounds like the only way to catch it
would be to put a sniffer on it, or maybe even look at it's arp cache right
after it happens and see if any of the machines in the cache are the
culprit.
