Onie Service Discovery - Dell EMC S4112F-ON Installation Manual

During the initial setup, the switch boots to ONIE Install. ONIE Install boots with ONIE Discovery to the console (ONIE:).
NOTE: For more information, see the
After you have securely installed and powered on the S4112-ON Series switch, to configure your switch, see your third-party ONIE-
compatible OS or the Dell EMC OS documentation.

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.
You can install an operating system manually from HTTP, FTP, or TFTP using the onie-nos-install <URL> command.
NOTE: If you have a recovery USB plugged into your switch, remove it before installing the DIAG-OS using the onie-nos-
install command.
The ONIE Install environment uses DHCP to assign an IP address to the management interface—eth0. If that fails, it uses the default IP
address 192.168.3.10/255.255.255.0.
To display the IP address, use the ifconfig eth0 command, as shown.
ONIE:/ # ifconfig eth0
eth0 Link encap:Ethernet HWaddr 90:B1:1C:F4:9C:76
inet addr:10.11.53.33 Bcast:10.255.255.255 Mask:255.0.0.0

To assign an IP address to the management interface, eth0, and verify network connectivity, use the ifconfig eth0 <ip
address> command, as shown.
ONIE:/ # ifconfig eth0 10.11.53.33/16
Verify the network connection with ping.
ONIE:/ # ping 10.11.8.12
