How does an SNMP trap work?

It only sends out SNMP messages when prompted by a request from the SNMP manager. However, if the agent detects an emergency event on the device that it is monitoring, it will send out a warning message to the manager without waiting to be polled for data. This emergency message is called a trap.

What are SNMP tools?

SNMP monitoring tools are programs or hardware that help network administrators manage their network using - you guessed it - the Simple Network Management Protocol (SNMP).
