Preferred Authenticated Host Interconnect Access

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 interconnect is implemented by an internal Ethernet-over-USB connection, running an IP stack. Oracle ILOM is given an internal, non-routable IP address that a client on the host can use to connect to it.

Unlike the KCS interface, which relies on protected access to a hardware device, the LAN interconnect is available to all operating system users by default. Therefore, connecting to Oracle ILOM over the LAN interconnect requires authentication, just as if the connection were coming over the network to the Oracle ILOM management port.

In addition, all services or protocols exposed on the management network are made available over the LAN interconnect to the host. It is possible to use a web browser on the host to access the Oracle ILOM web interface or use a Secure Shell client to connect to the Oracle ILOM command-line interface. In all cases, a valid user name and password must be provided to use the LAN interconnect.

The LAN interconnect is disabled by default. When it is disabled, there is no Ethernet device visible to the host operating system and the channel does not exist. Oracle Hardware Management Pack helps provision and configure the LAN interconnect.

For information about managing Oracle ILOM through a secure dedicated host interconnect connection, see one of the following:
