4.21.3.1 SEL Forwarding
When BMC SEL events are generated through any mechanism other than the Add SEL Entry
command, the BMC will send time-stamped copies of these events to the Intel
®
RMM). Events
are forwarded even if the BMC’s SEL is full.
4.21.3.2 BMC Status Change Forwarding
The BMC sends notifications of other status change events that may be of interest to the
registered add-in device. The BMC does not require the add-in device to take any action based
on the event data.
4.21.4 Serial Routing
The BMC provides support for the optional IPMI command, Set Serial Routing Mux, which
supports implementations where an add-in card can take over responsibility for serial port
sharing from the BMC. The command enables an add-in card or adjunct management controller
to direct the BMC to route serial connections to the add-in card or to allow the connections to be
handled by the BMC. Logically, this action can be viewed as controlling a hardware multiplexer
(serial routing mux) that routes the serial signals between the BMC and the add-in card,
although this specification does not describe or require a particular hardware implementation for
supporting this capability.
4.21.4.1 Serial Routing and SOL
SOL may be supported by either the BMC, using SOL in accordance with the IPMI 2.0
Specification, or by the Intel
®
RMM using Telnet. For the Intel
®
RMM-based method, the Intel
®
RMM must gain control of the serial mux from the BMC.
If the BMC is utilizing its UART interface when the command is received (for instance for BMC-
based SOL or EMP) then it will immediately close the session and the serial channel will appear
as disabled.
SOL cannot be routed through both the Intel
®
RMM and the BMC simultaneously.
4.21.5 Messaging Interfaces
This section describes the supported BMC communication interfaces:
 Host SMS Interface via low pin count (LPC) / (KCS) interface
 Host SMM Interface via low pin count (LPC) / keyboard controller style (KCS) interface
 Intelligent platform management bus (IPMB) I
2
C interface
 PCI SMBus
 Emergency management port (EMP) using the IPMI over Serial / Modem protocols for
serial remote access.
 LAN interface using the IPMI-over-LAN protocols
