White Paper - Remote Management SNMP SubAgent

7. Intel® Baseboard In-band SNMP Sub-Agent
The Intel®® Baseboard SNMP Sub-agent supports SNMPv1 and SNMPv2c versions. This is in-band
agent. It communicates to the BMC using the driver that supports the IPMI specification. This way sub-
agent runs on an Intel server in the OS, and gets information on all the platform sensors. Different
flavors of Microsoft® Windows*, RHEL* and SUSE* operating systems are supported. The key features
supported by in-band agent for the EPSD server boards include information on the sensors, chassis,
memory, and processor. The details of MIB for voltage and temperature sensors are shown in Exhibit
5. It also provides the health of each sensor and overall health of Intel server board. It supports GET,
GET-NEXT and SET commands to the SNMP management application. The SET command is supported
to modify the sensor thresholds. SNMP traps are generated whenever the state of sensor is changed.
See section 7.1 for details. The out-of-band SNMP agent runs on the BMC FW, and has limited support;
see section 6 for details.
Following is the list of sensors supported by the in-band SNMP sub-agent.
• Chassis intrusions
• Processor
• Memory
• Power supply
• Voltage
• System FAN
• Temperature
• Drive Slot Presence

7.1 SNMP Trap Events
In order to parse and understand the SNMP trap, the management application must know the MIB of
the generated trap such that it can take appropriate action. Additionally, the management application
should be configured, by its IP address, in the SNMP agent to receive the trap. The Intel® SNMP
subagent sends the trap for every new entry in the SEL inserted by the BMC. One or more SNMP
