operations.

GetBulk --

New for SNMPv2. The GetBulk operation was added to make it easier to

acquire large amounts of related information without initiating repeated get
operations. GetBulk was designed to virtually eliminate the need for GetNext
operations.

Set --

Allows the NMS to set values for object instances within an agent.

Trap --

Used by the agent to asynchronously Inform the NMS of some event. The

SNMPv2 trap message is designed to replace the SNMPv1 trap message.
Inform --

New for SNMPv2. The Inform operation was added to allow one NMS to

send trap information to another.

SNMPv1 messages (packets) contain two parts

unit (PDU) specifying the operation to be performed ("Get," "Set," and so on) and the
object instances involved in the operation.
