7.3 IPMI Messaging
All IPMI messages contain a Network Function Code field, which defines the category for a
particular command. Each category has two codes assigned to it—one for requests and one for
responses. The code for a request has the least significant bit of the field set to zero, while the
code for a response has the least significant bit of the field set to one.
Table 7-1 lists the network
function codes (as defined in the IPMI specification) used by the IPMC.
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

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
