Nvidia Cumulus v3.7 Switch Initial Setup¶
Further installation requires a Console and Internet connectivity via the management port!
If the switch has pre-installed network operating system (NOS), it needs to be uninstalled first.
NOS Uninstall (if pre-installed)
To uninstall the current NOS, access ONIE from the GRUB menu and select the Uninstall OS option.
Once it’s done, the switch will automatically reboot and get ready for the installation of the Cumulus Linux.
If there is no DHCP in the management network, stop the onie-discovery service and configure an IP address and default gateway manually.
ip addr add <management IP address/prefix> dev eth0
ip route add default via <gateway of the management network>
echo "nameserver <DNS server address>" > /etc/resolv.conf
The Cumulus image should be available on a web server to which the switch has access through the local network or the Internet.
After completion of the installation, the switch will automatically reboot.
To login use the default username and password for Cumulus v3.7:
