A.8 Command Line Interface (CLI)
A.8.1 Invoking the CLI
When the boot process begins, the computer starts its Power On Self Test (POST) sequence.

A.8.2 Operation
The CLI resembles a Linux shell, where the user can run commands to configure and manage one
or more PXE port network interfaces. Each port is assigned a network interface called neti,
where i is 0, 1, 2,...<#of interface>. Some commands are general and are applied to all network
interfaces. Other commands are port specific, therefore the relevant network interface is speci-
fied in the command.
