IPMI Fimware
By default the MMC waits endlessly for this information. If an endless wait is to be avoided, it is possi-
ble to set a timeout time after which the system will be switched off unconditionally. For the setting of
the timeout refer to the IPMI Chapter of the AMC module’s user guide.
7 LAN Functions
7.1 Over view
The IPMI controller supports IPMI over LAN (IOL) and Serial over LAN (SOL). Common for both types of
communication is the use of the RMCP / RMCP+ protocol for the packing of the data to be transferred.
The RMCP/RMCP+ protocol uses the TCP port 623 by default.
While IOL serves to transport IPMI commands and their responses via Gigabit Ethernet, SOL serves to
transport any serial data via Gigabit Ethernet. In each case, the IPMI controller serves as a protocol
encoder and decoder. IOL is able to use both RMCP and RMCP+ protocols. SOL works only with the
RMCP+ protocol.
Please note that IOL and SOL need the Ethernet device to be powered. Therefore, the board (payload)
must be fully powered.
For information on IOL/SOL support, refer to the user guide provided with the CompactPCI board/AMC
module.
7.2 Setting Up the Ethernet Channel
There are two methods to configure the LAN settings (IOL/SOL) for the Ethernet channels:
» By use of the kIpmi net uEFI Shell command in the uEFI BIOS
» By use of the open-source tool “ipmitool” or IPMI commands
The setup methods are compatible, i.e. both methods show the parameters which are set by the other
one.
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 port 623 is not used in parallel by payload and IOL/SOL.
7.3 Basic Setup from uEFI Shell
With the kIpmi net command from the uEFI Shell some basic settings such as IP address, sub-net mask
and gateway address can be set up for the Ethernet channels.
