Platform Management ArchitectureIntel® Server Board SE7520BD2 Technical Product Specification
88 Revision 1.3
4.2.5.5 LAN Interface
The baseboard supports one DPC LAN interface via a UDP port 26Fh. The mBMC supports a
maximum of one simultaneous session across all authenticated channels. The baseboard
implements gratuitous ARP support according to the IPMI 1.5 Specification.
The IPMI Specification v1.5 defines how IPMI messages, encapsulated in RMCP packet format,
can be sent to and from the mBMC. This capability allows a remote console application to
access the mBMC and perform the following operations:
• Chassis Control, e.g., get chassis status, reset chassis, power-up chassis, power-down
chassis
• Get system sensor readings
• Get and Set system boot options
• Get Field Replaceable Unit (FRU) information
• Get System Event Log (SEL) entries
• Get Sensor Data Records (SDR)
• Set Platform Event Filtering (PEF)
• Set LAN configurations
In addition, the mBMC supports LAN alerting in the form of SNMP traps that conform to the IPMI
Platform Event Trap (PET) format.

4.2.6 Direct Platform Control (IPMI over LAN)
Direct Platform Control provides a mechanism for delivering IPMI Messages directly to the
management controllers via a LAN connection. The NICs and the management controllers
remain active on standby power, enabling the IPMI Messaging when the system is powered up,
powered down, and in a system sleep state. This allows a remote console application to be able
to access the management controller capabilities, including:
• Power on/off and reset control with the ability to set BIOS boot flags
• FRU, SDR, and SEL access
• BMC configuration access
• Remote NMI Generation
• Ability to transfer IPMI messages between the LAN interface and other interfaces, such
as the System Interface, IPMB, and PCI SMBus. This capability enables messages to be
