Platform Management Functional Overview Intel® Server Board S1200V3RP 6.11.3.5.1 Static IP Address (IP Address Source Values 0h, 1h, and 3h) The BMC supports static IP address assignment on all of its management NICs. The IP address source parameter must be set to static before the IP address; the subnet mask or gateway address can be manually set. The BMC takes no special action when the following IP address source is specified as the IP address source for any management NIC:1h - Static address (manually configured). The Set LAN Configuration Parameter command must be used to configure LAN configuration parameter 3, IP Address, with an appropriate value. The BIOS does not monitor the value of this parameter, and it does not execute DHCP for the BMC under any circumstances, regardless of the BMC configuration. 6.11.3.5.2 Static LAN Configuration Parameters When the IP Address Configuration parameter is set to 01h (static), the following parameters may be changed by the user:  LAN configuration parameter 3 (IP Address)  LAN configuration parameter 6 (Subnet Mask)  LAN configuration parameter 12 (Default Gateway Address) When changing from DHCP to Static configuration, the initial values of these three parameters will be equivalent to the existing DHCP-set parameters. Additionally, the BMC observes the following network safety precautions: 1. The user may only set a subnet mask that is valid, per IPv4 and RFC 950 (Internet Standard Subnetting Procedure). Invalid subnet values return a 0xCC (Invalid Data Field in Request) completion code, and the subnet mask is not set. If no valid mask has been previously set, default subnet mask is 0.0.0.0. 2. The user may only set a default gateway address that can potentially exist within the subnet specified above. Default gateway addresses outside the BMC's subnet are technically unreachable and the BMC will not set the default gateway address to an unreachable value. The BMC returns a 0xCC (Invalid Data Field in Request) completion code for default gateway addresses outside its subnet. 3. If a command is issued to set the default gateway IP address before the BMC's IP address and subnet mask are set, the default gateway IP address is not updated and the BMC returns 0xCC. If the BMC's IP address on a LAN channel changes while a LAN session is in progress over that channel, the BMC does not take action to close the session except through a normal session timeout. The remote client must re-sync with the new IP address. The BMC's new IP address is only available in-band through the Get LAN Configuration Parameters command. 6.11.3.5.3 Enabling/Disabling Dynamic Host Configuration (DHCP) Protocol The BMC DHCP feature is activated by using the Set LAN Configuration Parameter command to set LAN configuration parameter 4, IP Address Source, to 2h: "address obtained by BMC 56 Revision 1.0

Platform Management Functional Overview
Intel® Server Board S1200V3RP
6.11.3.5.1
Static IP Address (IP Address Source Values 0h, 1h, and 3h)
The BMC supports static IP address assignment on all of its management NICs. The IP address
source parameter must be set to
static
before the IP address; the subnet mask or gateway
address can be manually set.
The BMC takes no special action when the following IP address source is specified as the IP
address source for any management NIC:1h – Static address (manually configured).
The
Set LAN Configuration Parameter
command must be used to configure LAN configuration
parameter 3,
IP Address
, with an appropriate value.
The BIOS does not monitor the value of this parameter, and it does not execute DHCP for the
BMC under any circumstances, regardless of the BMC configuration.
6.11.3.5.2
Static LAN Configuration Parameters
When the IP Address Configuration parameter is set to 01h (static), the following parameters
may be changed by the user:
LAN configuration parameter 3 (IP Address)
LAN configuration parameter 6 (Subnet Mask)
LAN configuration parameter 12 (Default Gateway Address)
When changing from DHCP to Static configuration, the initial values of these three parameters
will be equivalent to the existing DHCP-set parameters. Additionally, the BMC observes the
following network safety precautions:
1.
The user may only set a subnet mask that is valid, per IPv4 and RFC 950 (
Internet
Standard Subnetting Procedure
). Invalid subnet values return a 0xCC (Invalid Data Field
in Request) completion code, and the subnet mask is not set. If no valid mask has been
previously set, default subnet mask is 0.0.0.0.
2.
The user may only set a default gateway address that can potentially exist within the
subnet specified above. Default gateway addresses outside the BMC’s subnet are
technically unreachable and the BMC will not set the default gateway address to an
unreachable value. The BMC returns a 0xCC (Invalid Data Field in Request) completion
code for default gateway addresses outside its subnet.
3.
If a command is issued to set the default gateway IP address before the BMC’s IP
address and subnet mask are set, the default gateway IP address is not updated and the
BMC returns 0xCC.
If the BMC’s IP address on a LAN channel changes while a LAN session is in progress over that
channel, the BMC does not take action to close the session except through a normal session
timeout. The remote client must re-sync with the new IP address. The BMC’s new IP address is
only available in-band through the
Get LAN Configuration Parameters
command.
6.11.3.5.3
Enabling/Disabling Dynamic Host Configuration (DHCP) Protocol
The BMC DHCP feature is activated by using the
Set LAN Configuration Parameter
command
to set LAN configuration parameter 4,

e, to 2h: “address obtained by BMC
