All Oracle servers with Oracle ILOM have a dedicated management port used for connecting to Oracle ILOM over a network. Using the dedicated management port provides a private and secure network for management. Some systems also support sideband management that allows both the host and Oracle ILOM to be accessible on the standard server data ports. Using sideband management simplifies cable management and network configuration by preventing the need for two separate network connections. However, it also means that Oracle ILOM traffic could potentially be sent over an untrusted network if the dedicated or sideband management port is not connected to a trusted network.
To maintain the most reliable and secure environment for Oracle ILOM, the dedicated network management port or the sideband management port on the server must always be connected to an internal trusted network or dedicated secure management/private network.
