An IPMI response message (see Table 7-4 ) is similar to an IPMI request message. The main
difference is that the seventh byte contains the Completion Code, and the eighth byte and
beyond hold data received from the controller (rather than data to send to the controller). Also,
the Slave Address and Logical Unit Number for the requester and responder are swapped.
7.5 SIPL Protocol
The IPMC supports the Serial Interface Protocol Lite (SIPL) protocol. It supports raw IPMI
messages in SIPL and handles these messages the same way as it handles IPMI messages from
the IPMB-0 bus, except that the replies route to either the payload or serial debug interface.
Messages are entered as case-insensitive hex-ASCII pairs, separated optionally by a space, as
shown in the following examples:
[18 00 22]
[180022]
The IPMC does not, however, support SIPL ASCII text commands, as defined by the IPMI
specification.
