4.29 LAN Interface
The BMC implements both the IPMI 1.5 and IPMI 2.0 messaging models. These provide out-of-
band local area network (LAN) communication between the BMC and the external world.
The BMC supports a maximum of three LAN interfaces:
Two of the LAN interfaces utilize the embedded Intel
Controller Hub NICs (one channel per embedded NIC).
One LAN interface utilizes an optional external NIC known as the Intel
NIC requires the presence of the optional Intel
card.
See the IPMI 2.0 specification for details about the IPMI-over-LAN protocol.
4.29.1
IPMI 1.5 Messaging
The communication protocol packet format consists of IPMI requests and responses
encapsulated in an IPMI session wrapper for authentication, and wrapped in an RMCP packet,
which is wrapped in an IP/UDP packet. Although authentication is provided, no encryption is
provided, so administrating some settings, such as user passwords, through this interface is not
advised.
Session establishment commands are IPMI commands that do not require authentication or an
associated session.
The BMC supports None (no authentication), Straight Password / Key and MD5 authentication
types over the LAN interface.
