ONIE service discovery ONIE attempts to locate the installer through a number of discovery methods, as shown. To download and run an installer, the ONIE Service Discovery feature uses the first successful method found. 1. Passed 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. Inexact URLs based on DHCPv4 responses. 5. Query to IPv6 link-local neighbors using HTTP for an installer. 6. TFTP waterfall - from DHCPv4 option 66 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 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. The following is an example of the ifconfig eth0 command. 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 inet6 addr: fe80::92b1:1cff:fef4:9c76/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:18 errors:0 dropped:0 overruns:0 frame:0 TX packets:24 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:1152 (1.1 KiB) TX bytes:6864 (6.7 KiB) Interrupt:21 Memory:ff300000-ff320000 To assign an IP address to the management interface (eth0) and verify the network connectivity, use the ifconfig eth0 command, as shown in the following example.

ONIE service discovery
ONIE attempts to locate the installer through a number of discovery methods, as shown. To download and run an installer, the
ONIE Service Discovery feature uses the first successful method found.
1.
Passed 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.
Inexact URLs based on DHCPv4 responses.
5.
Query to IPv6 link-local neighbors using HTTP for an installer.
6.
TFTP waterfall — from DHCPv4 option 66
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.
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.
The following is an example of the
ifconfig eth0
command.
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 the network connectivity, use the
ifconfig eth0
<ip address>
command, as shown in the following example.
ONIE:/ # ifconfig eth0 10.11.53.33/16
Verify the network connection with ping.
ONIE:/ # ping 10.11.8.12
