SNMP functionality requires the following two components:
Network management station – A network management station hosts management applications, which monitor and control managed nodes.
Managed node – A managed node is a device such as a server, router, or hub that hosts SNMP management agents that are responsible for carrying out requests from management stations, such as a service processor (SP) running Oracle ILOM. Managed nodes can also provide unsolicited status information to a management station in the form of a trap.
SNMP is the protocol used to communicate management information between management stations and SNMP agents.
The SNMP agent is preinstalled on your Oracle server and runs on Oracle ILOM, so all SNMP management occurs through Oracle ILOM. To use this feature, your operating system must have an SNMP client application.
Both management stations and agents use SNMP messages to communicate. Management stations can send and receive information. Agents can respond to requests and send unsolicited messages in the form of traps. Management stations and agents use the following functions:
Get
GetNext
GetResponse
Trap
