Prestige 334 User’s Guide
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.
