The ONL Sub-Project is under the direction of the OCP Networking Project Group.
ONL currently supports 110+ Networking Switches of which many are either OCP Accepted™ or Inspired™.
ONL maintains a certification program for validation of network switch hardware with ONL. A designation of ONL Certified is applied to switches that pass ONL conformance testing. A separate Gold status certification is available to vendors who provide materials for ongoing testing.
The generic ONL testing guide is located Here
The ONL git repository is hosted on GitHub: https://github.com/opencomputeproject/OpenNetworkLinux.
