The Host-to-ILOM Interconnect interface allows clients on the host operating system to communicate with Oracle ILOM 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. This connection is enabled by default in Oracle Solaris operating system.
Connecting to Oracle ILOM over the Host-to-ILOM 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. 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 LAN interconnect.
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.
