64, it would then generate for itself an IP of 1:2:3:4:215:17ff:fefe:2f62. The IP, Prefix, and Gateway are read-
only parameters to the BMC user in this mode.
IPv6 can be used with the BMC’s Web Console, JViewer (remote KVM and Media), and Systems Management
Architecture for Server Hardware – Command Line Protocol (SMASH-CLP) interface (ssh). There is no
standard yet on how IPMI RMCP or RMCP+ should operate over IPv6 so that is not currently supported.
6.10.3.4 LAN Failover
The BMC FW provides a LAN failover capability such that the failure of the system HW associated with one
LAN link will result in traffic being rerouted to an alternate link. This functionality is configurable via IPMI
methods as well as via the BMC’s Embedded UI, allowing for user to specify the physical LAN links constitute
the redundant network paths or physical LAN links constitute different network paths. BMC will support only a
all or nothing” approach – that is, all interfaces bonded together, or none are bonded together.
The LAN Failover feature applies only to BMC LAN traffic. It bonds all available ethernet devices but only one
is active at a time. When enabled, If the active connection’s leash is lost, one of the secondary connections is
automatically configured so that it has the same IP address(the next active LAN link will be chosen randomly
from the pool of backup LAN links with link status as “UP”). Traffic immediately resumes on the new active
connection.
The LAN Failover enable/disable command may be sent at any time. After it has been enabled, standard IPMI
commands for setting channel configuration that specify a LAN channel other than the first will return an error
code.
6.10.3.5 BMC IP Address Configuration
Enabling the BMC’s network interfaces requires using the Set LAN Configuration Parameter command to
configure LAN configuration parameter 4, IP Address Source. The BMC supports this parameter as follows:
 1h, static address (manually configured): Supported on all management NICs. This is the BMC’s default
value.
 2h, address obtained by BMC running DHCP: Supported only on embedded management NICs.
IP Address Source value 4h, address obtained by BMC running other address assignment protocol, is not
supported on any management NIC.
Attempting to set an unsupported IP address source value has no effect, and the BMC returns error code
0xCC, Invalid data field-in request. Note that values 0h and 3h are no longer supported, and will return a 0xCC
error completion code.
6.10.3.5.1 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.
