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
Dedicated 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 Management Connection
The SER MGT port on the chassis provides a secure local serial
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
The number of ports varies depending on the server
You can optionally connect to Oracle ILOM and manage the
server remotely through one of the NET 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 might: (1) potentially decrease the connection
performance to Oracle ILOM, and (2) potentially create security
risks if Oracle ILOM traffic is transmitted over an untrusted
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,
N is the port number (0 through
3) depending on how your server is equipped.
A communication channel known as the Host-to-ILOM Interconnect
enables communication between the host OS and Oracle ILOM
without the use of the network management port. The Host-to-ILOM
Interconnect is particularly useful when you want to perform
these Oracle ILOM tasks locally:
The Host-to-ILOM Interconnect is also known as the
Dedicated Interconnect SP Management
Connection. Use this name when searching for
it in the Oracle ILOM documentation.
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.
