When a PXE boot occurs, it can impact Intel AMT features that may be active at the time of the boot. This occurs because the PXE boot protocol requires that the boot client release the IP address at the end of the process. When Intel AMT shares its IP address with the host, Intel AMT also loses its IP address. The following features may be impacted when this occurs.
• Storage Redirection – in the unlikely event that there is a Storage Redirection session active at the same time as a PXE boot, the session will be dropped immediately. The management console cannot recover until Intel AMT acquires an IP address. If this IP address is not the same as the released address, the console will have to wait for DNS registration of the new IP before it can reconnect.
• SOL – as with USB-R, the session may be dropped, although SOL is less time sensitive and may recover if the platform receives the same IP address. Otherwise, the console will have to wait for DNS registration.
• KVM – the behavior is similar to SOL: the session may be dropped, but if there is no activity on the management console side (keystrokes or mouse movements), the session may be maintained if the same IP is assigned. Otherwise, the console will have to wait for DNS registration.
• Remote Access – the session with the MPS will be dropped, but Intel AMT will reestablish the session within two minutes.
