CentOS - Jun 2018 - Semi-OT: ipmitool or ipmicfg: set BMC to use NIC 2

The man page isn't helping, nor have I been able to find examples that work.

For example, the man page claims I can do ipmitool lan get active, and I
try, and it says, "invaling lan command, get".

Do I set the MAC address for the lan to NIC 2? Anyone have a clue - I do
*not* want martians on the real network.

get isn't a recognized subcommand under lan in the ipmitool I have
installed.

This will be very dependent on your motherboard and its BMC capabilities.
Some can do IPMI on specific ports and not others. On the Intel S2600
series that I use they can use port 1, 2, and a dedicated RMM port, but not
ports 3 and 4. You'll need to check your mobo suppport docs to see if it
can even handle IPMI on  the second port. If so, you just configure it with
the IP setting you want for static, or configure the MAC shown by issuing
'lan print 2' in the ipmitool shell. Very often the MACs is sequential ,
so
you can guess it by looking at the MACs of the normal ethernet ports and
adding 1, 2 or whatever.

I should finish that sentence.

... or configure the MAC (shown by issuing 'lan print 2'  in the
ipmitool
shell) in your DHCP server. Though, running server management IPs in DHCP
isn't a great idea, because how do you access the management if the DHCP
server is down?

So you're saying I should set the MAC address for the lan channel 1 to the
MAC address of the second NIC?
