ONIE service discovery

ONIE attempts to locate the installer through several discovery methods, as shown. To download and run an installer, the ONIE Service
Discovery feature uses the first successful method found.
1 Pass from the boot loader.
2 Search locally attached storage devices for one of the ONIE default installer filenames—for example, USB.
3 Exact URLs from DHCPv4.
4 Report inexact URLs based on the DHCPv4 responses.
5 Query to the IPv6 link-local neighbors using HTTP for an installer.
6 Start TFTP waterfall—from the DHCPv4 option 66
Examples of ONIE ifconfig eth0 commands
If none of the ONIE Service Discovery methods are successful, you can disable this using the onie-discovery-stop command.
