Sun Microsystems X4150 manual SNMP MIB Files, MIBs Integration

Managed nodes are any number of devices, including servers, routers, and hubs, that host SNMP management agents responsible for carrying out the requests from management stations. 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 the management stations and agents.

The SNMP agent is preinstalled and runs on the ELOM, so all SNMP management of the server should occur through the ELOM. To utilize this feature, your operating system must have an SNMP client application. See your operating system vendor for more information. The SNMP agent on your ELOM provides inventory management and sensor and system state monitoring capabilities.

SNMP MIB Files

The base component of an SNMP solution is the management information base (MIB). MIB is a text file that describes a managed node’s available information and where it is stored. When a management station requests information from a managed node, the agent receives the request and retrieves the appropriate information from the MIBs. The Sun server supports the following MIB files. Download and install the MIB files from the Tools and Drivers CD. The files are located in the /SNMP/mib directory.

■The system group and SNMP group from RFC1213 MIB

■SNMP-FRAMEWORK-MIB

■SNMP-USER-BASED-MIB

■SNMP-MPD-MIB

■SUN-PLATFORM-MIB

■ENTITY-MIB

MIBs Integration

Use the MIBs to integrate the management and monitoring of the server into SNMP management consoles. The MIB branch is a private enterprise MIB, located at MIB object iso(1).org (3). dod (6) .internet (1) .private (4) .enterprises (1) .sun (42)

.products (2). See FIGURE 8-1. The standard SNMP port, 161, is used by the SNMP agent on the ELOM.
