Terminal Mode IPMI Message Bridging

Terminal mode supports the ability to bridge IPMI messages to another interface when binary
hex-ASCII IPMI commands are used. The message bridge is determined by the following: the
bridge field, whether the message is a request or a response, the message direction with respect to
the BMC and the LUN. Table 28 lists the supported BMC combinations for IPMI message
bridging. Any other combinations are unsupported.
Note that IPMI messages to and from the system interface are transferred using the BMC SMS
(System Management Software) LUN, 10b, and with the bridge field set to 00b.
