COMMAND DESCRIPTION
Get Allows the manager to retrieve an object variable from the agent.
GetNext Allows the manager to retrieve the next object variable from a table or list within an
agent. In SNMPv1, when a manager 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 manager to set values for object variables within an
agent. Trap Used by the agent to inform the manager of some events.
