One of the most popular features of an Intel® vPro™ technology-based device is remote access via remote KVM (Keyboard, Video, Mouse). The KVM feature allows remote control of a client even if the OS isn't running or if the system is asleep (also known as Out of Band). While traditional KVM requires additional software to access a client system, Intel vPro technology’s KVM feature provides KVM over IP with no additional equipment or software required. The only requirement is that Intel® Active Management Technology (Intel® AMT) firmware must be configured.

The KVM feature was first introduced with the release of Intel AMT 6.0, and since then it has gone through various improvements for supported screen resolutions and support for multiple monitors. The specific capabilities of each Intel AMT version can be found on the supported screen resolution and multiple monitor support page of the SDK documentation.

Intel AMT KVM connections are usually made via some sort of virtual network computing (VNC) connection on either the Remote Frame Buffer (RFB) ports or redirection ports.

The RFB port is what VNC viewers normally use. These viewers require RFB protocol version 3.8. Some of the viewers supporting the protocol are Ultra VNC*, Tight VNC*, and Real VNC*. The RFB 3.8 protocol uses port 5900 exclusively.

The redirection port corresponds with RFB protocol RFB 4.0. In this case the viewers that support the protocol are RealVNC Plus*, KVMview*, and MeshCommander*. RFB 4.0 supports ports 16994 and 16995 (Transport Layer Security (TLS)). The authentication for the viewers are handled on ports 16992 and 16993 (TLS).

NOTE: Intel vPro technology-branded devices (Intel® Core™ i5, i7, and m5 processors and Intel® Xeon® processor E3 family-based systems) are the only Intel AMT devices that support the KVM feature.
