631xESB / 632xESB I/O Controller Hub Embedded LAN Channels
Even though the Intel
®
631xESB / 632xESB I/O Controller Hub embedded NICs are shared by
the BMC and the server, sharing means only that both the BMC and the server use the same
NIC. These shared NICs provide a dedicated MAC address solely for BMC use. As a result, in
some ways these channels are more similar to a dedicated LAN channel than a shared channel.
The IP address for the server is always different from the BMC IP address for a particular
embedded NIC.
For these channels, support can be enabled for IPMI-over-LAN, ARP, and DHCP.
As an integral part of the I/O Controller Hub, the BMC has a high degree of access to and
control over its primary network interfaces. Subsequent sections describe how the BMC
configures the I/O Controller Hub to enable these enhanced features.
All LAN features for a given LAN channel are disabled unless the channel’s access mode is set
to Always Enabled.
If an Intel
®
RMM add-in card is installed, then the I/O Controller Hub embedded LAN channels
are configured differently than for a server that does not include this device. See section
4.21
for information.
4.29.4 Address Resolution Protocol Support
The BMC can receive and respond to ARP requests on Intel
®
631xESB / 632xESB I/O
Controller Hub NICs, and can also generate gratuitous ARPs.
The BMC’s default configuration on its first power on, or when the private store map changes or
is corrupted, is for all ARP generation to be disabled.
4.29.5 Internet Control Message Protocol Support
The BMC supports the following ICMP message types targeting the BMC over Intel
®
631xESB /
632xESB I/O Controller Hub NICs:
 Echo request (ping) – The BMC sends an Echo Reply
 Destination unreachable – If message is associated with an active socket connection
within the BMC, the BMC closes the socket
 Redirect – The BMC updates its internal routing table
 Timestamp Request – The BMC sends a Timestamp Reply
4.29.6 Serial-over-LAN (SOL) 2.0
The BMC supports the IPMI 2.0 defined SOL feature. Platforms that use the Intel® 5000 Series
Chipset do not support the previous generation Intel proprietary SOL, now known as SOL 1.0.
IPMI 2.0 introduces a standard serial-over-LAN feature, which is implemented as a standard
payload type (01h) over RMCP+.
