setup option to allow one of these baseboard ports to be dedicated to the BMC for
manageability purposes. When this is enabled, that port is hidden from the OS.
6.12.3.2.3 Concurrent Server Management Use of Multiple Ethernet Controllers
The BMC FW supports concurrent OOB LAN management sessions for the following
combination:
 2 on-board NIC ports
 1 on-board NIC and the optional dedicated RMM4 add-in management NIC.
 2 on-board NICs and optional dedicated RMM4 add-in management NIC.
All NIC ports must be on different subnets for the above concurrent usage models. MAC
addresses are assigned for management NICs from a pool of up to 3 MAC addresses allocated
specifically for manageability.
The Intel
®
Server Board S1400SP4 has seven MAC addresses programmed at the factory.
MAC addresses are assigned as follows:
• NIC 1 MAC address (for OS usage)
• NIC 2 MAC address = NIC 1 MAC address + 1 (for OS usage)
• NIC 3 MAC address = NIC 1 MAC address + 2 (for OS usage)
• NIC 4 MAC address = NIC 1 MAC address + 3 (for OS usage)
• BMC LAN channel 1 MAC address = NIC1 MAC address + 4
• BMC LAN channel 2 MAC address = NIC1 MAC address + 5
• BMC LAN channel 3 (RMM) MAC address = NIC1 MAC address + 6
The Intel
®
Server Board S1400SP2 has five MAC addresses programmed at the factory. MAC
addresses are assigned as follows:
 NIC 1 MAC address (for OS usage)
 NIC 2 MAC address = NIC 1 MAC address + 1 (for OS usage)
 BMC LAN channel 1 MAC address = NIC1 MAC address + 2
 BMC LAN channel 2 MAC address = NIC1 MAC address + 3
 BMC LAN channel 3 (RMM) MAC address = NIC1 MAC address + 4
The printed MAC address on the server board and/or server system is assigned to NIC1 on the
server board.
For security reasons, embedded LAN channels have the following default settings:
 IP Address: Static
 All users disabled
IPMI-enabled network interfaces may not be placed on the same subnet. This includes the
Intel
®
Dedicated Server Management NIC and either of the BMC’s embedded network
interfaces.
Host-BMC communication over the same physical LAN connection – also known as “loopback”
– is not supported. This includes “ping” operations.
On server boards with more than two onboard NIC ports, only the first two ports can be used as
BMC LAN channels. The remaining ports have no BMC connectivity.
Maximum bandwidth supported by BMC LAN channels are as follows:
