P-202H Plus v2 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 object variables within an agent.
• Trap
Used by the agent to inform the NMS of some events.
