Technical Product Specification

Intel® Server Board S1600JP TPS Platform Management Functional Overview
4.6.4.3
Concurrent Server Management Use of Multiple Ethernet Controllers
Provided the HW supports a management link between the BMC and a NIC port, the BMC FW
supports concurrent OOB LAN management sessions for the following combination:
 Two on-board NIC ports
 One on-board NIC and the optional dedicated add-in management NIC
 Two on-board NICs and optional dedicated 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 three MAC addresses
allocated specifically for manageability. The total number of MAC addresses in the pool is
dependent on the product HW constraints (for example, a board with two NIC ports available for
manageability would have a MAC allocation pool of two addresses).
For these channels, support can be enabled for IPMI-over-LAN and DHCP.
For security reasons, embedded LAN channels have the following default settings:
 IP Address: Static
 All users disabled
Network failover mode must be used for IPMI capable interfaces that are on the same subnet.
Host-BMC communication over the same physical LAN connection – also known as “loopback”
– is not supported. This includes “ping” operations.
On baseboards 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 LAN 1 (Baseboard NIC port)
100M (10M in DC off state)
BMC LAN 2 (Baseboard NIC port)
100M (10M in DC off state)
BMC LAN 3 (Dedicated NIC)
1000M

IPv6 Support
In addition to IPv4, the Intel
®
Server Board S1600JP supports IPv6 for manageability channels.
Configuration of IPv6 is provided by extensions to the IPMI Set and Get LAN Configuration
Parameters commands as well as through a Web Console IPv6 configuration web page.
The BMC supports IPv4 and IPv6 simultaneously so they are both configured separately and
completely independently. For example, IPv4 can be DHCP configured while IPv6 is statically
configured or vice versa. The parameters for IPv6 are similar to the parameters for IPv4 with the
following differences:
 An IPv6 address is 16 bytes versus 4 bytes for IPv4.
 An IPv6 prefix is 0 to 128 bits whereas IPv4 has a 4 byte subnet mask.
