A.2.1 LAN controller interface selection
The MMC firmware provides an OEM IPMI command to allow users to switch the
MMC connected NC-SI interface between one front panel LAN IO RJ-45 connector
and the Base interface. These commands can be used to read out the actual selected
IPMI-over-LAN / Serial-over-LAN interface and to change the selection.
LAN controller interface selection settings:
00h: Front panel LAN IO
01h: Base Interface LAN BI (default)

A.2.2LAN controller channel selection and priority
In addition to the selected LAN controller interface, users may need to configure each
single LAN controller channel (port) as dedicated NC-SI interface to the BMC.
Additional OEM commands for the configuration of the NC-SI LAN controller channel
selection and priority are provided to allow a flexible configuration.
LAN channel selection priority setting list:
0 = The first channel that links up, gets the NC-SI connection to the BMC.
1 = Channel 1 is the preferred port if it is up, otherwise use channel 2 if it is up.
2 = Channel 2 is the preferred port if it is up, otherwise use channel 1 if it is up.
3 = Channel 1 is the only allowed port, always use it, never change to channel 2.
