Usage Guidelines
iPXE is an open source implementation of the Preboot eXecution Environment (PXE). Bootloaders boot an
image located on an HTTP, FTP, or a TFTP server.
If the forever keyword is configured, the switch sends Dynamic Host Configuration Protcol (DHCP) requests
forever. If the timeout keyword is configured, DHCP requests are sent for the specified amount of time, and
when the timeout expires, the switch reverts to device boot.
