Sys Commands (0x32)

There are and will be a variety of sys specific commands.

Cablecheck - SubCommand 0x00

The cablecheck command checks whether the BMC is seeing traffic between itself and the host's NIC. Sys specifies which if_name is expected to be connected. The BMC presently only checks traffic on the interface specified. There are now ethernet statistics available over IPMI, which can be checked directly in lieu of this.

Request

Byte(s)ValueData
0x000x00Subcommand
0x01If_name lengthWhere you expect the cable, eth0 or eth1, etc
0x02 ...The nameThe string, not null-terminated

Response

Byte(s)ValueData
0x000x00Subcommand
0x010x00/0x010 for false, 1 for true

CpldVersion - SubCommand 0x01

Any CPLD on the system that can only be read directly via the BMC can have its version exported to Sys via the cpld version command.

Request

Byte(s)ValueData
0x000x01Subcommand
0x01CPLD IDA one-byte identifier for the CPLD file to read, unsigned byte.

Response

Byte(s)ValueData
0x000x01Subcommand
0x01MajorMajor version
0x02MinorMinor Version
0x03Sub 1Third version number
0x04Sub 2Fourth version number

Per the above, if the version number doesn't fit in a byte it'll be cast to size.

GetNcsiEthDevice - SubCommand 0x02

The BMC itself must have hard-coded into the image, which ethernet device is connected to the host NIC. This is true also in the mapping of ethernet device to channel number. The channel number is used to configure the ethernet device over IPMI, instead of the interface name. This is because we leverage the current IPMI command set to read and write the networking configuration. Sys can be programmed already to have this information in the board protobuf, however, this information -- can be read from the BMC over IPMI.

Request

Byte(s)ValueData
0x000x02Subcommand

Response

Byte(s)ValueData
0x000x02Subcommand
0x01Channel numberThe IPMI channel number for use with the network configuration commands (such as reading the MAC or IP address of the BMC).
0x02if_name lengthThe length of the if_name in bytes.
0x03...if_nameThe interface name, not null-terminated

DelayedHardReset - SubCommand 0x03

Sys needs to be able to tell the BMC to reset the host but given a delay in seconds.

Request

Byte(s)ValueData
0x000x03Subcommand
0x01..0x04Seconds to delay (uint32)

Response

Byte(s)ValueData
0x000x03Subcommand
