Oracle ILOM 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.
|
|
|
Dedicated Local Management Connection
|
SER MGT
|
-
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 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.
|
Dedicated Network Management Connection
|
NET MGT
|
-
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.
|
Shared Sideband Network Management Connection
|
NET0–NET3
Note -
The number of ports varies depending on the server
model.
|
-
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 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,
NETN,
where N is the port number
(for example, 0, 1, 2, or 3) depending on how your
server is equipped.
-
To establish a remote sideband management connection
to Oracle ILOM, see Configuring SP Sideband Management or refer to Sideband
Network Management Connection in the Oracle ILOM Administrator's Guide for
Configuration and Maintenance, Firmware Release
4.0.

Host-to-ILOM Interconnect
|
Internal
|
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:
-
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 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.
Note -
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.

To enable the Host-to-ILOM Interconnect, refer to one
