Oracle ILOM In-band (Sideband) Management

Note -
By default, you connect to the server's SP using the out-of-band NET MGT port. The Oracle
ILOM sideband management feature enables you to select either the NET MGT port or one of
the server's Gigabit Ethernet ports (named NET n), which are in-band ports, to send and receive
Oracle ILOM commands to and from the server SP. In-band ports are also called sideband ports.
The advantage of using a sideband management port to manage the server's SP is that one
fewer cable connection and one fewer network switch port are needed. In configurations where
numerous servers are being managed, such as data centers, sideband management can represent
a significant savings in hardware and network utilization.
When sideband management is enabled in Oracle ILOM, the following conditions might occur:
Connectivity to the server SP might be lost when the SP management port configuration is
■
changed while you are connected to the SP using a network connection, such as SSH, web,
or Oracle ILOM Remote Console.
In-chip connectivity between the SP and the host operating system might not be supported
■
by the on-board host Gigabit Ethernet controller. If this condition occurs, use a different port
or route to transmit traffic between the source and destination targets instead of using L2
bridging or switching.
Server host power cycles might cause a brief interruption of network connectivity for server
■
Gigabit Ethernet ports that are configured for sideband management. If this condition
occurs, configure the adjacent switch or bridge ports as host ports.
