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.

  1. 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.

  1. NOS Install

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:


  1. Set up the Out-of-Band (OOB) Management.

Open the network interfaces file and add the IP address and other required details.

sudo vim /etc/network/interfaces
# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
auto eth0
iface eth0 inet static
       address <management IP address/prefix length>
       gateway <gateway of management network>

source /etc/network/interfaces.d/*
echo "nameserver <dns server>" | sudo tee /etc/resolv.conf
sudo ifreload -a
  1. Cumulus Linux license installation.

sudo cl-license -i

Copy/paste the Cumulus Linux license string, then press ctrl-d.

  1. Netris agent installation.

Navigate to the Net–>Inventory section and click the three vertical dots (⋮) on the right side of the switch you are provisioning. Then click Install Agent and copy the one-line installer command to your clipboard.
