Table 21 Send message data fields (continued)
Message data for sending requests (RQ) and
responses (RS)
Target channel protocolTarget channel type
NOTE: Terminal mode has a single, fixed SWID
for the remote console. Software using send
message to deliver a message to a terminal mode
remote console should use their SWID or slave
address as the source of the request or response,
and the terminal mode SWID (40h) as the
destination.

NOTE: MC adds session handle information
when it puts the message into the receive message
queue .
1
The session handle identifies a particular active session on the given channel. The MC assigns a different value to each
time a new session is activated. A typical implementation keeps track of the last value that was assigned and increment
it before assigning it to a new active session when the activate session command has been accepted. Software
must include this field for channels where the get channel info command indicates that the channel supports sessions.
Get system GUID command
This command is available to the MC.
This optional, though highly recommended, command can be used to return a GUID (also known
as a UUID), for the managed system to support the remote discovery process and other operations.
The format of the ID follows the octet format specified in [RFC 4122]. [RFC4122] specifies four
different versions of UUID formats and generation algorithms suitable for use for a GUID in IPMI.
Time based — version 1 (0001b)
Name based:
version 3 (0011b) MD5 hash
version 4 (0100b) Pseudo-random
version 5 SHA1 hash
[SMBIOS] does not specify a particular specification or version for UUID generation. In general,
if it remains unspecified, the version 1 format is recommended by the IPMI specification for new
