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 eld
• Whether the message is a request or a response
• The message direction with respect to the BMC and the LUN.
Table 23 lists the supported BMC combinations for IPMI message bridging. No other combinations
are supported. IPMI messages to and from the system interface are transferred using the BMC SMS
(System Management Software) LUN, 10b, and with the bridge eld set to 00b.

functionality Message is a response to an earlier
request from the remote console to the BMC
00b Request In 10b Remote Console request to SMS Message is a
request from the remote console to SMS via the
Receive Message Queue
00b Response Out 10b SMS Response to Remote Console Message is a
response to an earlier request from SMS
01b Response Out Any Response to earlier Bridged Request from
Remote Console Message is the asynchronous
response from an earlier bridged request that
was encapsulated in a Send Message command
issued to the BMC by the remote console
Table 24. Terminal Mode Text Commands
Command Switches Description
SYS PWD -U USERNAME
<password>
Used to activate a terminal mode session. USERNAME
corresponds to the ASCII text for the username. <password>
represents a printable password (up to 16 characters). If
<password> is not provided, then a null password (all binary 0) is
submitted. Passwords are case sensitive.
Either the SYS PWD command (or Activate Session IPMI message)
must be successfully executed before any command or IPMI
messages are accepted. Note that a modem connection may be
automatically dropped if multiple bad passwords are entered.
-N <password> -N represents a Null username. <password> represents a printable
password (up to 16 characters). If <password> is not provided,
then a null password (all binary 0) is submitted. Passwords are
case sensitive.
Either the SYS PWD command (or Activate Session IPMI message)
must be successfully executed before any command or IPMI
messages are accepted. Note that a modem connection may be
automatically dropped if multiple bad passwords are entered.
-X -X immediately logs out any presently active session. Entering an
invalid password with -U or -N also has the same effect.
