managed objects. SNMP allows a manager and agents to communicate for the purpose of accessing
these objects.
SNMP itself is a simple request/response protocol based on the manager/agent model. The manager
issues a request and the agent returns responses using the following protocol operations:
•
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.
