Intel® Server Board S1200V3RP Platform Management Functional Overview running DHCP". Once this parameter is set, the BMC initiates the DHCP process within approximately 100 ms. If the BMC has previously been assigned an IP address through DHCP or the Set LAN Configuration Parameter command, it requests that same IP address to be reassigned. If the BMC does not receive the same IP address, system management software must be reconfigured to use the new IP address. The new address is only available in-band, through the IPMI Get LAN Configuration Parameters command. Changing the IP Address Source parameter from 2h to any other supported value will cause the BMC to stop the DHCP process. The BMC uses the most recently obtained IP address until it is reconfigured. If the physical LAN connection is lost (that is, the cable is unplugged), the BMC will not reinitiate the DHCP process when the connection is re-established. 6.11.3.5.4 DHCP-related LAN Configuration Parameters Users may not change the following LAN parameters while the DHCP is enabled: LAN configuration parameter 3 (IP Address) LAN configuration parameter 6 (Subnet Mask) LAN configuration parameter 12 (Default Gateway Address) To prevent users from disrupting the BMC's LAN configuration, the BMC treats these parameters as read-only while DHCP is enabled for the associated LAN channel. Using the Set LAN Configuration Parameter command to attempt to change one of these parameters under such circumstances has no effect, and the BMC returns error code 0xD5, "Cannot Execute Command. Command, or request parameter(s) are not supported in present state." 6.11.3.6 DHCP BMC Hostname The BMC allows setting a DHCP Hostname using the Set/Get LAN Configuration Parameters command. DHCP Hostname can be set regardless of the IP Address source configured on the BMC. But this parameter is only used if the IP Address source is set to DHCP. When Byte 2 is set to Update in progress, all the 16 Block Data Bytes (Bytes 3 - 18) must be present in the request. When Block Size is less than 16, it must be the last Block request in this series. In other words Byte 2 is equal to Update is complete on that request. Whenever Block Size is less than 16, the Block data bytes must end with a NULL Character or Byte (=0). All Block write requests are updated into a local Memory byte array. When Byte 2 is set to Update is Complete, the Local Memory is committed to the NV Storage. Local Memory is reset to NULL after changes are committed. When Byte 1 (Block Selector = 1), firmware resets all the 64 bytes local memory. This can be used to undo any changes after the last Update in Progress. Revision 1.0 57
