IPMI Over LAN (IOL)
IPMI over LAN is used to allow the IPMI controller to communicate with the MMC via LAN using
the RMCP or RMCP+ protocol. The data which is transferred are IPMI commands and the re-
sponses to them.
To enable the LAN support after parameter setup this command has to be issued:
Please note that the following commands must use the IP address which belongs to the en-
abled channel.
The open tool “ipmitool” can serve as a control program and user interface for this. “ipmitool”
allows the issuing of raw IPMI commands such as:
or to call complex functions like 'mc info':
This uses many raw IPMI commands to get all needed information.

Serial Over LAN (SOL)
Serial over LAN connects the COM1 or /dev/ttyS0 respectively of the AM5030's payload side
to an Ethernet channel. The MMC resides between this serial interface and one of the Ethernet
channels. It serves as an encoder and a decoder for the used RMCP+ protocol and controls
the data stream. Outside the AM5030 for example, the open tool “ipmitool” can be used to drive
the SOL session i.e. it offers a console function to communicate via Ethernet with the AM5030's
serial interface.
The serial interface can be used as a connection, for example:
• To a user program on the AM5030 payload
• To the BIOS console redirection function. Refer to the BIOS setup menu “Main>Serial
Port Console Redirection”. There the serial parameters for this purpose can be set.
Please note that after BIOS start, the OS gets active in most cases (except e.g. DOS)
and the console redirection stops working because the OS doesn't use BIOS functions
to drive the console.
• To a Linux login console. This can be activated after payload start, for example. by the
command:
SOL supports and requires serial hardware handshake. This should be activated for the serial
port. Otherwise transmitted data might get lost. In any case the same serial parameters for the
used payload side serial interface and the MMC's serial interface must be used. The
parameters for the MMC's serial interface can be set by the ‘ipmitool sol set …’ command.
Calling ‘ipmitool sol set’ shows all options that can be set.
