Hi FreeIPMI Team,

I have been struggling with an issue for couple of days now. I am using an
open source tool called MAAS (v1.9) for provisioning OS on physical
servers. This tool primarily relies uses bmc-config commands.

Target hardware is some proprietary Intel based server (not HP/Dell) which
has BMC chip on it. It also has multiple LAN channels (1,2,3) where 1 & 2
being an in band NIC and channel 3 being dedicated BMC interface. Eth
interfaces of Channel 1 and  Channel 3 are connected in a common broadcast
domain and get the IPs from a common DHCP server.

The following are the set of bmc-config commands that gets triggered by
MAAS on the host (on which OS will be installed).

bmc-config, --checkout, --key-pair=Lan_Conf:IP_Address_Source
bmc-config, -L
bmc-config, --checkout, --key-pair=User2:Username
bmc-config, --checkout, --key-pair=User3:Username
bmc-config, --checkout, --key-pair=User4:Username
bmc-config, --checkout, --key-pair=User5:Username
bmc-config, --checkout, --key-pair=User6:Username
bmc-config, --checkout, --key-pair=User7:Username
bmc-config, --checkout, --key-pair=User8:Username
bmc-config, --checkout, --key-pair=User9:Username
bmc-config, --checkout, --key-pair=User10:Username
bmc-config, --checkout, --key-pair=User11:Username
bmc-config, --checkout, --key-pair=User12:Username
bmc-config, --checkout, --key-pair=User13:Username
bmc-config, --checkout, --key-pair=User14:Username
bmc-config, --checkout, --key-pair=User15:Username
bmc-config, --commit, --key-pair=User6:Username=maas
bmc-config, --commit, --key-pair=User6:Password=DYJuTLXmrljoGl
bmc-config, --commit, --key-pair=User6:Enable_User=Yes
bmc-config, --commit, --key-pair=User6:Lan_Privilege_Limit=Administrator
bmc-config, --commit, --key-pair=User6:Lan_Enable_IPMI_Msgs=Yes
bmc-config, --checkout, --key-pair=User6:Username
bmc-config, --checkout, --key-pair=User6:Lan_Privilege_Limit
bmc-config, --checkout, --key-pair=User6:Lan_Enable_IPMI_Msgs
bmc-config, --checkout, --key-pair=Lan_Conf:IP_Address


All of these commands gets executed successfully however on *Lan Channel 1
interface*. I* want this to be set to IP address assigned to Lan Channel 3*
(i.e Dedicated BMC interface). Thats my objective because MAAS tool uses
Lan_Conf:IP_Address for provisioning OS & it achieves this over couple of
power cycles of target host. The problem is that, since *Lan_Conf:IP_Address
*is pointing to the IP on Lan Channel 1, that IP would not  be available
once the server is switched off and that blocks the provisioning workflow.

So I have tried following so far,

I tried appending '*--lan-channel-number=3*' on those bmc-config commands
(listed above) & got '*invalid channel number*' in response.

But when i execute *ipmitool -H 10.6.0.21 -U tocp -P tocp lan print 3*
