Platform Management Functional Overview
6.10.3.2.3 Concurrent Server Management Use of Multiple Ethernet Controllers
The BMC FW supports concurrent OOB LAN management sessions for the following
combination:
Two on-board NIC ports

One on-board NIC ports and the optional dedicated RMM4 add-in management NIC

Two on-board NIC ports and the 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 server board 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 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 setting:
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:
BMC LAN1 (Baseboard NIC port) ----- 100Mb (10Mb in DC off state)

BMC LAN2 (Baseboard NIC port) ----- 100Mb (10Mb in DC off state)

BMC LAN3 (Dedicated NIC) ----- 1000Mb (10Mb in DC off state)

