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.
