2. SNMPv1 Operations
SNMP itself is a simple request/response protocol. 4 SNMPv1 operations are defined as below.
•
Get
Allows the NMS to retrieve an object variable from the agent.
•
GetNext
Allows the NMS to retrieve the next object variable from a table or list within an agent. In
SNMPv1, when a NMS wants to retrieve all elements of a table from an agent, it initiates a Get
operation, followed by a series of GetNext operations.
•
Set
Allows the NMS to set values for the object variables within an agent.
•
Trap
Used by the agent to inform the NMS of some events.
There are two parts in an SNMPv1 message. The first part contains a version number and a community name.
The second part contains the actual SNMP protocol data unit (PDU) specifying the operation to be performed
