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 an SP running ILOM.
The management station monitors nodes by polling management agents for the appropriate information using queries. 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 agents.
The SNMP agent is preinstalled on your Sun server platform and runs on ILOM, so all SNMP management occurs through ILOM. To utilize this feature, your operating system must have an SNMP client application.
