This architecture requires the following three components to perform Serial over LAN operations.

1.SOL-capable firmware executing on the Intelligent Platform Management Controller (IPMC)

The IPMC also provides a dedicated SMBus connection to the base interface Ethernet controller. This connectivity is not shared with IPMB-0 or any other I2C/ SMBus/IPMB connections that the IPMC may provide on the blade for hardware management.

2.The base interface Ethernet controller, which provides a sideband interface port to the IPMC over which SOL traffic is redirected

The Ethernet controller also filters packets based on MAC address, RMCP port number, or IP address and forwards the packets to the IPMC over the sideband interface.

3.Client software running on any remote node that has LAN access to the blade whose serial port data is to be accessed

The IPMC is responsible for controlling the serial hardware MUX, the transformation
