7-3
Table 7-1: Network Function Codes
Hex Code
Value(s): Name: Type: Name:
00, 01 Chassis chassis device
requests/responses
00 = command/request, 01 = response:
common chassis control and status functions
02, 03 Bridge bridge
requests/responses
02 = request, 03 = response:
message contains data for bridging to the next
bus. Typically, the data is another message,
which also may be a bridging message. This
function is only present on bridge nodes.
04, 05 Sensor/
Event
sensor and event
requests/responses
04 = command/request, 05 = response:
for configuration and transmission of Event
Messages and system Sensors. This function
may be present on any node.
06, 07 App application
requests/responses
06 = command/request, 07 = response:
message is implementation-specific for a
particular device, as defined by the IPMI
specification
08, 09 Firmware firmware transfer
requests/responses
08 = command/request, 09 = response:
firmware transfer messages match the format
of application messages, as determined by the
particular device
0A, 0B Storage non-volatile
storage
requests/responses
0A = command/request, 0B = response:
may be present on any node that provides
nonvolatile storage and retrieval services
0C-2F reserved – reserved: 30 network functions (15 pairs)
30-3F OEM – 30 = command/request, 3F = response:
vendor specific: 16 network functions (8 pairs).
The vendor defines functional semantics for
cmd and data fields. The cmd field must hold the
same value in requests and responses for a
given operation to support IPMI message
handling and transport mechanisms. The
controller’s Manufacturer ID value identifies the
vendor or group.
