Automatic Synchronization of IP Addresses

Release 7.0 adds the capability to Intel AMT to synchronize to the host’s IP address. Set the following property in the AMT_EthernetPortSettings instance for the wired LAN interface to enable this feature (CIM_EthernetPort.DeviceID equals “Intel(r) AMT Ethernet Port 0”; use the CIM_ElementSettingData association to find the correct instance of AMT_EthernetPortSettings):

Property

Value

AMT_EthernetPortSettings.IpSyncEnabled

TRUE (Default value is FALSE)

With this setting, Intel AMT notifies the LMS to monitor the host IP address. When the LMS detects that the host has a dynamic IP address, it sets IPS_HostIPSettings.DHCPEnabled to TRUE. Intel AMT gets its IP address by monitoring DHCP packets.

note-icon Note:

Prior to Intel AMT Release 9.0, it was the UNS which was notified to monitor the host IP address.  Beginning in Release 9.0, the UNS and LMS were combined under the title LMS.  See Local Manageability Service.

 

When the LMS detects that the host has a static IP address, it verifies that the host also has a valid DNS server address and a valid default gateway address. Then the LMS updates the IPS_HostIpSettings object with the host values for IP address, subnet mask, DNS server(s) and default gateway. The LMS also detects when the host IP address changes.

 Note:

   This feature only applies to the wired interface, using IPv4 addressing.  Therefore, this feature is not available on LAN-less platforms.

   If the host does not have a static IP address, Intel AMT waits until the host acquires one. This can lock out access to Intel AMT.
