NMSs use these operations to determine which variables a managed device supports and to sequentially
gather information from variable tables (such as the IP routing table) in the managed devices.

Traps
The managed devices asynchronously report certain events to NMSs using traps.
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.
