Text Command Format
Text commands do not support the bridging and sequence number fields present in the hex-
ASCII commands, are case sensitive, and are preceded by a prefix consisting of the string SYS.
Examples
Hex-ASCII command example (IPMI Reset Watchdog Cmd):
[18 00 22]<CR>
[1C 00 22 00]<CR-LF>
Text command example:
[SYS TMODE]<CR>
[OK TMODE]<CR-LF>
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 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 field set
to 00b.

to the BMC by the remote console
