As a faster alternative to the KCS interface, clients on the host operating system can communicate with Oracle ILOM over an internal high-speed interconnect. The Oracle Hardware Management Pack refers to this feature as Host-to-ILOM Interconnect. The Oracle ILOM interface refers to this feature as Local Host Interconnect. This interconnect is implemented by an internal Ethernet-over-USB connection, running an IP stack. Oracle ILOM and the host are given internal non-routable IP addresses for communication over this channel.
Connecting to Oracle ILOM over the Host-to-ILOM interconnect (Local Host Interconnect) requires authentication, just as if the connection were coming over the network to the Oracle ILOM management port. All services or protocols exposed on the management network are made available over the Host-to-ILOM interconnect to the host. For example, it is possible to use a web browser on the host to access Oracle ILOM's web interface or use a Secure Shell client to connect to Oracle ILOM CLI. In all cases, a valid user name and password must be provided to use the Host-to-ILOM interconnect.
The Oracle Hardware Management Pack installer presents the option of enabling the Host-to-ILOM interconnect. Oracle recommends that the Host-to-ILOM interconnect be enabled only if the networking instruction supports RFC 3927 and the ability to have link-local IPv4 addresses. Also, care should be taken to ensure that the operating system is not acting as a bridge or router. This ensures that management traffic between the host and Oracle ILOM remains private.
