Hi, fivealive:

I'll bet David H. Lipman will know EXACTLY what this is (seems to be related to networking and something right up his alley). :)

In the interim, a quick Google search of "SNMP trap" turned up a wikepedia article and several more:


Mostly geek-speak to me, but it seems to be legit?

LOL, yes I do.

SNMP - Simple Network Management Protocol

There are two parts for SNMP which uses the UDP protocol (SNMP 161 & SNMP Trap 162).

SNMP is loaded on a system or device and using an associated platform related Management Information Base (MIB) you can query the device for its state and health.

Additionally there is a SNMP Trap daemon loaded on a centralized system (Network Management Station - NMS) that receives alerts from systems and devices and keeps records of the alert events. For example if a system has a fault it will send a datagram over UDP port 162 message to the NMS (SNMP Trap IP address).

SNMP is well known and there is a plethora of information on the 'net describing SNMPv1, SNMPv2 and SNMPv3.

Wireshark can decode SNMP trap messages and in "C:\Program Files\Wireshark\snmp\mibs" are various Management Information Bases (MIBs).

SNMP can also be used internally by a Windows system through the Windows Management Instrumentation (WMI)
