Log into the IPMI web interface by entering the IP address into the URL of a web browser on a client system. Go to Configuration > Network, and scroll down to the drop-down list for LAN Interface, or Default Interfaces.
The default setting is Fail Over, which chooses to use either the dedicated IPMI port or the first LAN port, depending on connection status. Choosing Dedicated LAN forces IPMI through only the dedicated port, and Shared will force IPMI through only the first LAN port.
Example screenshots are shown below for a X9DRW-3F motherboard.
If the IPMI web interface is not available, you can also set the LAN mode from command line with IPMICFG or ipmitool, using raw codes. The raw codes use the following format:
# ipmicfg -raw 0x30 0x70 0x0c
# ipmitool raw 0x30 0x70 0x0c
The options and return codes will be in single or multiple integers ranging from 0 to 2. For instance, showing the current LAN mode on a X9DR3-F motherboard would look like this:
Where the "02" return code indicates that the board is using the failover mode. Bear in mind that the codes will differ depending on your motherboard hardware and BMC firmware, so the various permutations for the option field are presented in the table below. Be sure to insert spaces between each integer.
|X8 ATEN Firmware||X9 ATEN Firmware||X8 AMI Firmware||X9 AMI Firmware|

|Set to dedicated||1 1 0||1 0||1 1 0||1 0|
|Set to shared||1 1 1||1 1||1 1 1||1 1|
