Not all functionalities are covered with a standard set of IPMItool commands. Therefore, a set of custom NVIDIA IPMItool raw commands have been added. The first two parameters of the raw command are NetFN and CMD.

IPMItool raw commands follow the following format:

ipmitool -C 17 -I lanplus -H <bmc_ip_addr> -U <username> -P <password> raw <netfunc> <cmd> <data>


  • netfunc – network function which identifies the functional message class, and clusters IPMI commands into sets
  • cmd – one byte command within a network function
  • data – optional element which provides additional parameters for a request or response message

The following table lists the supported IPMItool raw commands. Use the following template to run these commands: 

ipmitool -C 17 -I lanplus -H <bmc_ip_addr> -U <username> -P <password> raw <netfunc> <cmd> <data>
