The Host-to-ILOM Interconnect Interface

The Host-to-ILOM interconnect is an alternative to the standard, slower Keyboard Controller Style (KCS) internal interface for service processor communication. The Host-to-ILOM interconnect allows clients on the host operating system to communicate with the Oracle ILOM service processor over an internal high-speed 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. For systems that support it, the Host-to-ILOM interconnect is enabled by default in Oracle Solaris.

From the host, you can connect and log in to Oracle ILOM over the Host-to-ILOM interconnect just as if the connection were coming over the network to the system's network management (NET MGT) port. All services or protocols exposed on the management network are made available over the Host-to-ILOM interconnect. As long as valid Oracle ILOM credentials are provided, the Host-to-ILOM interconnect can be used for both browser-based web access or CLI-based Secure Shell client access to Oracle ILOM.

Oracle recommends that your network support 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 over the Host-to-ILOM interconnect remains private.

Oracle recommends unique passwords be created for each user on each Oracle ILOM service processor so that a compromised password could not be used against other systems with Oracle ILOM.
