6.13.4 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 responses to them.
To enable the LAN support after parameter setup this command has to be issued:

ipmitool lan set access on

Please note that the following commands must use the IP address which belongs to the
enabled channel.
The open tool ‘ipmitool’ can serve as a control program and user interface for this. ipmitool
allows to issue generic IPMI commands such as:

ipmitool -I lanplus -H 192.168.3.189 -U admin -P admin –A PASSWORD raw 6 1

or to call complex functions like ‘mc .info’:

ipmitool -I lanplus -H 192.168.3.189 -U admin -P admin –A PASSWORD mc info

This uses many generic IPMI commands to get all needed information.

6.13.5 Serial Over LAN (SOL)

Serial over LAN connects the COM1 or /dev/ttyS0 respectively of the AM5010’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 AM5010 e.g. 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
AM5010’s serial interface.
The serial interface can be used as a connection
1) to a user program on the AM5010 payload, or
2) to the BIOS console redirection function. Refer to the BIOS setup menu

“Advanced>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.

3) to a Linux login console. This can be activated after payload start, for example. by the

command
getty –h 115200 /dev/ttyS0

4) etc.
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.
Other commands which are possible are shown when issuing “ipmitool sol help”.
