This interface is available from either of the available NIC ports in system that can
be shared with the host. Only one NIC may be enabled for management traffic at any time. To
change the NIC enabled for management traffic, please use the “Write LAN Channel Port” OEM
IPMI command. The default active interface is port 1 (NIC1).
Interface 2: This interface is available from the optional RMM3 which is a dedicated
management NIC that is not shared with the host.
For these channels, support can be enabled for IPMI-over-LAN and DHCP.
For security reasons, embedded LAN channels have the following default settings:
