Nvidia Cumulus v3.7 Switch Initial Setup

Note

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.

onie-discovery-stop

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.

Example:

onie-nos-install http://192.168.100.10/cumulus-linux-3.7.15-mlx-amd64.bin

After completion of the installation, the switch will automatically reboot.

To login use the default username and password for Cumulus v3.7:

cumulus/CumulusLinux!

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

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

# 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
