LAN Functions
10.1
Overview
The two Ethernet channels on the AMC Fabric Interface and also the two Ethernet channels on
the front panel can - in parallel to their 'normal' use - be used for the following special purposes:
• IPMI over LAN (IOL)
• Serial over LAN (SOL)
Common for both kinds of communication is the use of the RMCP/RMCP+ for the packing of
the data to be transferred. On Ethernet the port 623 is used for transfers with this protocol.
While IOL serves to transport IPMI commands and their responses, the SOL serves to
transport any serial data. In each case the MMC serves as a protocol encoder and decoder.
Please note that IOL is able to use both RMCP and RMCP+ protocols. SOL works only with the
RMCP+ protocol. In addition, both IOL and SOL require that the payload Ethernet device be
powered. Therefore the module (payload) must be fully powered.
The following table shows the assignment of the four IOL / SOL channels to the Gigabit
Ethernet interfaces.

Setting up the Ethernet Channel
There are two methods to prepare the MMC's SOL and IOL LAN parameters for the four
possible Ethernet channels:
• In the uEFI BIOS from the EFI-Shell using ‘
kipmi net
’
• By use of the open tool “ipmitool” or raw IPMI commands (via KCS or IPMB-L)
Both of the methods are compatible with one another, meaning that they both set or show the
exact same parameters as the other.
The setup is separate for all four channels. When the MAC addresses are set the ones which
are programmed into the hardware must be re-used. This is a restriction. The IP addresses of
a channel being used by 'normal' payload traffic and IOL/SOL traffic may differ but need not
differ as long as the RMCP port 623 is not used in parallel by payload and IOL/SOL.
