This section provides some additional configuration specific to Cumulus VX and shows some basic commands you can try to get started with Cumulus Linux. Additional resources for further reading and more advanced configuration are also provided.
Perform Additional Configuration
To provide easier access in video-focused hypervisors (such as VirtualBox), Cumulus VX is configured by default to redirect the grub menu and the kernel output to the video console. Follow the steps below to send both the grub menu and the kernel output back to the serial console.
If the VM has not been booted:
Interrupt the boot process at the GRUB prompt.
Modify the Linux command line directly, removing all references to the console entries:
Configured Version:The example images above are for the ONIE-RESCUE entry, not the standard boot entry. The configuration process is the same for both entries.
Start the VM.
If the VM is already running:
Run the following commands as the sudo user:
- Restart the VM to implement the change.
Try Basic Commands
After you have configured the Cumulus VX instances and performed additional configuration, use the wider Cumulus Linux documentation suite to help you configure and test features, and fine tune the network topology.
This section provides some basic commands to get you started. You can run the commands on each VM to see system information, as well as interface and LLDP details and to change the hostname of a switch.
To get information about the switch itself, run the
net show system command:
To show every available interface that is physically UP, run the
net show interface command:
To get topology verification, run the
net show lldp command.
The example output below shows the two-leaf/two-spine Cumulus VX network topology from CumulusVX-leaf1, where local port swp1 is connected to remote port swp1 on CumulusVX-spine1 and local port swp2 is connected to remote port swp1 on CumulusVX-spine2.
To change the hostname, run the
net add hostname command.
This command updates both the
