Serial Over LAN (SOL)—MPCBL0010 SBC
11.0 Serial Over LAN (SOL)
Serial over LAN (SOL) is a packet format and protocol defined in the IPMI v2.0
specification for transmitting serial port data over Ethernet using IPMI over LAN
(RMCP+) messages. This two-way redirection of a blade's serial port data over Ethernet
is independent of the operating system or any applications executing on it. The BIOS
also supports redirection of its console over serial port, which can be redirected over
the network for remote access.
The SOL mechanism, coupled with a SOL client utility executing on a remote node,
enables viewing of serial port data from any IPMI v2.0-based, SOL-enabled blade, and
thus provides a virtual remote terminal server for accessing a blade’s serial port
character stream.

11.2 SOL Architecture
The SOL implementation on the MPCBL0010 Single Board Computer is based on the
definition in Section 15 of the IPMI v2.0 specification.
11.2.1 SOL Implementation
Serial over LAN (SOL) enables suitably designed blades and servers to transparently
redirect a serial character stream of a baseboard UART to/from a remote client via LAN
over RMCP+ sessions. This capability enables users at remote consoles to access the
serial port of a blade/server and interact with a text-based BIOS console, operating
system, command line interfaces, and serial text-based applications.
