Do you have any sort of SNMP running?

Essentially an SNMP trap is a trigger to PUSH from a device to the server.

SNMP has different flavors of authentication, but you should make sure the community and passwords match.

If you know the device info, you may be able to get it from there.  (eg: see what the device is trying to use and get that info from the device).
