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. Search locally attached storage devices for one of the ONIE default installer filenames—for example, the filename is: onie

self update from the USB.

2. Query to the IPv4 and IPv6 link-local neighbors using HTTP for an installer.

3. Exact URLs from DHCPv4.

4. Discover TFTP-based image from the DHCP server.

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, you must 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 UP

Verify the network connection with ping.

ONIE:/ # ping 10.11.8.12
