Overview of SNMP Subagents
Intel
®
Server SNMP (Simple Network Management Protocol) subagents are SNMP extension
agents that provide interfaces and databases for retrieving server hardware information and for
monitoring server health status on the network using SNMP.
The Management Information Base (MIB) file that accompanies each SNMP subagent contains the
definitions of the management information the SNMP subagent can access, with each definition
distinguished by a unique object identifier (OID). Each SNMP subagent listed below has its own
MIB file and OID. The SNMP subagents support SNMP-based access (GETs, SETs and TRAPs)
to the instrumented components on the managed server, collecting and returning information as
requested by a management system. The subagents plug into the SNMP master agent infrastructure
supported by the operating system and respond to queries and sets filtered to the subagents by the
master agent, based on the OID specifying the data defined in the MIB to be retrieved or set.

For systems running the Windows operating system, the SNMP subagent is implemented as a
dynamic link library (DLL) and is configured in the Registration Database. When the SNMP
master agent (Snmp.exe) is started, it queries the registry, then loads and initializes the DLL for the
registered SNMP subagent. The SNMP master agent invokes DLL entry points to request MIB
queries and sets, and obtains events generated by the subagent.
