Configuring the Intel AMT IP Address

The Intel AMT IP address can be either an IPv4 address or, starting with Release 6.0, an IPv6 address. There are three ways that the address can be configured:

   Intel AMT and the host have a shared dynamic IP address (IPv4 only). The IP address is issued by a DHCP server on request by the host. Intel AMT either detects DHCP address requests and responses, or starting with Release 7.0, requests IP address updates via the Local Manageability Server (from Release 9.0) or the User Notification Service (UNS) (releases prior to 9.0).

   Intel AMT and the host have different static IP addresses (wired interface only). This is valid but requires two IP addresses per platform. Set the two IP addresses directly.

   Starting with Release 7.0, Intel AMT and the host can share a static IP address (wired interface only). There are two ways to do this:

Configure the Intel AMT IP address directly using the AMT_EthernetPortSettings and set the SharedIP property to true.

With Release 7.0, Intel AMT, in conjunction with the LMS (Release 9.0) or UNS (prior to Release 9.0), can detect the host IP address and synchronize the Intel AMT address to the host address (IPv4 only).

Note that using static IP addresses limits access to certain Intel AMT features that depend on the presence of a DHCP server.

A configuration where Intel AMT gets its IP address dynamically, while the host has a static IP, is invalid.

Earlier releases supported a configuration where the host has a dynamic IP and Intel AMT has a static IP. Starting with Release 7.0, this is an invalid configuration.

To summarize,

Intel AMT Setting

Host Set to Static IP

Host Set to DHCP

Static IP

Applies only to wired interface

Not supported, starting from Release 7.0

DHCP

Not supported

Supported on both wired and wireless interfaces

IPv4: Shared IP

IPv6: Dedicated IP

 

 Note:

   Intel AMT and the host never share the same IPv6 address, whether it is a DHCPv6, Router Advertisement or manually configured IP address.

   Intel AMT does not support a static IP address on a wireless interface.
