Intel MPCBL0001 manual SOL User Information, LAN Parameters, Parameter Remarks

Serial Over Lan (SOL)

11.7.2SOL User Information

Intel’s SBCs implement four different users, User1 through User4. User1 has null username which is not editable. The script configures User2. User2 is enabled and specifically enabled for SOL payloads.

The user name is “solusername”, zero-padded to a length of 16 bytes as per the IPMI specification. The password is “soluserpassword”, zero-padded to 20 bytes as per the IPMI 2.0 extension.

11.7.3LAN Parameters

The reference script configures IPMI channel one. The IPMI channel number used by reference_cfg can be changed to any IPMI LAN channel supported by the target SBC.

For the MPCBL0001 SBC, channels one and two are LAN channels on the Base Interface and are enumerated by the OS as eth0 and eth1, respectively.

Since reference_cfg uses IPMI channel one, this means that for any SBC, eth0 will be routed to a switch in slot seven (may vary on different chassis implementations). If a user needs to route the serial data over IPMI LAN channel 2 (eth1 on the OS level), then the LAN channel default value in the reference_cfg script shall be changed to “2”.

Since the IPMC must directly send and receive IP packets (RMCP+), it needs certain information about its LAN connection in order to fill in the packets correctly. It gets this information via the Set LAN Configuration Parameters command. This one command can set many parameters based on the value of the Parameter Selector byte in the command. The following table shows which Parameter Selectors are necessary for establishing an SOL session. Note that each table entry requires a separate instance of the command.
