Oracle ILOM Management Connection Options

Before you can access Oracle ILOM, you must cable the server for a remote network management connection or a local serial management connection. You have the following options for establishing a management connection to the server service processor.

Management Connection
Management Port
Dedicated Remote Network Management Connection
The NET MGT port on the chassis is a dedicated in-band Ethernet port that securely segregates management traffic away from the host. By attaching an active LAN connection to the network management port (NET MGT), you can log in to Oracle ILOM through the web or through an SSH connection from a remote system on the network.
To maintain the most reliable and secure environment for Oracle ILOM, the dedicated network management port on the server must always be connected to an internal trusted network or dedicated secure management/private network.
Dedicated Local Serial Management Connection
The SER MGT port on the chassis provides a secure local connection to the Oracle ILOM command-line interface using a serial terminal or terminal emulator.
This connection is particularly useful when a local console is the only way to access and diagnose system failures, or when you need to modify the preconfigured Oracle ILOM network properties prior to establishing a LAN connection.
Shared Sideband Network Management Connection

Note -  Ethernet ports NET2 and NET3 are non-functional in single-processor systems.

You can optionally connect to Oracle ILOM and manage the server remotely through one of the 10GbE ports on the chassis by configuring a sideband management connection to Oracle ILOM. This eliminates the need to support two separate network connections for host and management traffic. However, this approach could: (1) potentially decrease the connection performance to Oracle ILOM, and (2) potentially create security risks if Oracle ILOM traffic is transmitted over an untrusted network.
To configure Oracle ILOM to transmit management traffic through a sideband management connection, you must change the default management port value from MGMT to one of the data ports on the server, NET0, NET1, NET2, or NET3.
Host-to-ILOM Interconnect
A communication channel known as the Host-to-ILOM Interconnect enables you to communicate locally with Oracle ILOM from the host operating system (OS) without the use of a network management connection (NET MGT) to the server. The Host-to-ILOM Interconnect is particularly useful when you want to perform these Oracle ILOM tasks locally:
  • All server management functions in Oracle ILOM that you typically perform from the command line, web, or IPMI interfaces through the network management (NET MGT) connection on the server.

  • All data transfers, such as firmware upgrades, to Oracle ILOM that you typically perform from the host over a Keyboard Controller Style (KCS) interface using IPMI flash tools. For these types of server management environments, the Host-to-ILOM Interconnect can provide a more reliable and potentially faster data transfer rate than traditional KCS interfaces.

  • All future server monitoring and fault detection operations that you typically perform from the host operating system through the use of Oracle enabled software tools and agents installed on the server.
