Cumulus VX is not a production-ready virtual switch or router. It has the same foundation as Cumulus Linux and Cumulus RMP, including all the control plane elements, but without an actual ASIC or NPU for line rate performance or hardware acceleration.

You can use tools like jdoo to monitor the virtual switch. The same automation, zero touch provisioning, security, and QoS tools are available.

The following table outlines the similarities and differences between Cumulus VX and other Cumulus Networks operating systems:

Feature or FunctionalityCumulus VX
Installation and UpgradeNew images available with every GA release.
Hardware accelerationDatapath forwarding is dependent on the choice of hypervisor and VM resources.
Hardware managementNone
Hardware limitationsNone. Dependent on hypervisor and VM resources. Certain features such as route-table-size might accommodate more routes than are supported in hardware (32K routes), given available memory.
Production-readyNo
Linux extensibilityYes
Layer 2 features
Yes; hypervisor/topology manager dependent.
Layer 3 featuresYes
Network virtualizationYes (software forwarding)
OS management (ZTP, ifupdown2, third party packages)
Yes
Automation, monitoring, troubleshootingYes
SecurityYes
QoSYes
