Baseboard SNMP Subagent Details
The baseboard SNMP Subagent has more features and allows more user interaction than the other
SNMP subagents installed by Intel® Server Manager 8. Consequently, this chapter is devoted
entirely to the baseboard SNMP subagent.
Figure 2 describes how the baseboard SNMP subagent interfaces with the SNMP master agent and
the BMC on the platform.

Figure 2. Baseboard SNMP Agent Architecture
There are two sources of information for the SNMP subagent on the server. The SNMP subagent
communicates with the Baseboard Management Controller (BMC) using an Intelligent Platform
Management Interface (IPMI) driver. Through the IPMI driver, the SNMP subagent has access to
information on components such as power supplies, voltages, temperature sensors, cooling devices,
chassis intrusion sensors, and the System Event Log (SEL). The SNMP subagent also has access to
information on processors and memory stored in the System Management BIOS (SMBIOS) tables.
