The serial port provides access to the ILOM web interface, the command-line interface (CLI), and the system console stream using serial port redirection.
The internal serial port is the connection between the host server and ILOM that allows an ILOM user to access the host serial console. The ILOM internal serial port speed must match the speed of the serial console port on the host server, often referred to as serial port 0, COM1, or /dev/ttyS0.
The external serial port is the RJ-45 serial port on ILOM. Typically the internal and external serial port connections should run at the same speed to avoid flow control issues when connecting to the host console from the ILOM external serial port.
