Where:
Returns the LUN that was passed in the Request Message.LUN
A return of the NetFn code that was passed in the Request Message. Except that an odd NetFn value
is returned.
NetFn
Return of the Cmd code that was passed in the Request Message.Cmd
Indicates whether the request completed successfully.Completion
Code
Zero or more bytes of data. The MC always returns a response to acknowledge the request, regardless
of whether data is returned.

LAN Interface
The LAN interface specifications define how IPMI messages can be sent to and from the MC
encapsulated in Remote Management Control Protocol (RMCP) packet datagrams. This capability
is also referred to as IPMI over LAN. IPMI also defines the associated LAN specific configuration
interfaces for settings things such as IP address other options, as well as commands for discovering
IPMI based systems.
The Distributed Management Task Force (DMTF) specifies the RMCP format. This same packet
format is used for non-IPMI messaging via the DMTF’s Alert Standard Forum (ASF) specification.
Using the RMCP packet format enables more commonality between management applications that
operate in an environment that includes both IPMI based and ASF based systems.
IPMI v2.0 defines and extended packet format and capabilities that are collectively referred to as
RMCP+ and defined under the IPMI specific portion of an RMCP packet. RMCP+ utilizes
authentication algorithms that are more closely aligned with the mechanisms used for the ASF 2.0
specification. In addition, RMCP+ adds data confidentiality (encryption) and payload capability.
In Moonshot, IPMI v2.0/RMCP+ is implemented for the LAN interface.
Remote Management Control Protocol (RMCP)
The Distributed Management Task Force (DMTF) has defined a RMCP for supporting pre-OS and
OS absent management. RCMP is a simple request-response protocol that can be delivered using
UDP datagrams. IPMI-over-LAN uses version 1 of the RMCP protocol and packet format.
RMCP includes a field that indicates the class of messages that can be embedded in an RMCP
message packet, including a class for IPMI messages. Other message classes are ASF and OEM.
An IPMI LAN implementation can also use ASF-class Ping and Pong messages to support the
discovery of IPMI managed systems on the network.
RMCP port numbers
RMCP uses two well-known ports under UDP. “RMCP Port Numbers” (page 154) describes these
ports and summarizes their use.
Table 122 RMCP Port Numbers
DescriptionNamePort#
The Primary RMCP Port — This port and the required RMCP messages must be
provided to conform with RMCP specifications.
Aux bus Shunt
(Primary RMCP Port)
623 (26Fh)
There is a mandatory set of messages required to be supported on this port.
These messages are always sent in the clear so that system software can discover
systems that have RMCP support.
Referred to as the secondary RMCP port or secure port, it is only used when it
is necessary to encrypt packets using an algorithm or specification that prevents

Port)

also sending unencrypted packets from being transferred via the same port.
