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.
