1. When ping is enabled and Intel AMT shares its IP address with the host, then Intel AMT will only respond to pings when the host OS is down or the OS is up but the interface driver (wired or wireless) is not present.
2.. When Intel AMT device is connected via a VPN tunnel or by an MPS connection, it will not respond to pings, even if ping response was enabled.
There is more about the General Settings here:http://software.intel.com/sites/manageability/AMT_Implementation_and_Reference_Guide/DOCS/Implementa...
Shut down the system using button in cabinet.
I'm able to get ping response(not RMCP ping), webui(http: // ipaddress:16992) and execute winrm commands
In AMT SDK It's mentioning about rmcp as below
Use RMCP Ping to Determine the Platform State
The following steps use the RMCP ping response to determine the state of a platform with Intel AMT.
1. Send an RMCP ping to the IP address of the platform under examination.
2. If there is no response, the cause may be one of the following reasons:
a. The platform is powered down or off the network.
b. The platform does not support Intel AMT.
c. The version of Intel AMT is earlier than Release 4.0, which was the first to support RMCP ping response.
d. The version is release 4.0 or later but the platform is not yet set up. (Intel AMT Release 6.1 and later releases will respond to an RMCP ping before setup is started or complete. The host must be active with a dynamic IPv4 address.)
e. The version is release 4.0 or later and the platform is configured, but the RMCP ping response is disabled.
f. The platform is Intel Small Business Technology, which does not support the ping feature.
All the above conditions are invalid . So can you explain whether AMT needs OS for responding RMCP ping. As per my understanding, sinceAMT is OOB, it can respond without OS, please correct me if I'm wrong
The short answer is that RMCP ping is mostly used for AMT discovery when AMT is un-provisioned(after AMT is provisioned you have easier ways to discover AMT). While AMT is un-provisioned , it will not stay powered in Sx (by default) in order to save power.
