Prestige 2302 Support Notes

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
