SNMP polling involves retrieving Management Information Base (MIB) variables from devices in order to determine faulty behavior or connection problems. Faulty devices or faulty connections are then diagnosed by applying predefined formulas to the extracted MIB variables.

What is the difference between SNMP poll and SNMP trap?

SNMP works in two ways: by polling or by traps. Polling consists of launching remote queries, either actively or on demand, carrying out operation queries synchronously. Traps, meanwhile, are messages sent by SNMP devices asynchronously, according to changes or events, to configured addresses.

What is SNMP polling and trap?

SNMP polls are queries sent from a monitoring application to a device using the available MIBs for the related devices. These are usually on a schedule say every 5 minutes. Traps are notifications sent from a device to a monitoring application trap receiver.
