Feature Profiles

Feature profiles define groups of OpenConfig paths that can be invoked on network devices. A feature profile may contain configuration, telemetry, operational or any other paths that a device exposes. Example management plane device APIs are gNMI, and gNOI. Example control plane APIs are gRIBI, and protocols such as BGP, IS-IS.

Feature profiles also include a suite of tests for validating the network device behavior for each defined feature.

Examples

Tests below are implemented using the ONDATRA test framework with the Kubernetes Network Emulation binding.

Arista cEOS

Arista cEOS images can be obtained by contacting Arista.

Nokia SR-Linux

SR Linux images can be found here and will require the SRL Controller to be installed on the KNE Kubernetes cluster.

Static Binding (Experimental)

The static binding supports ATE based testing with a real hardware device. It assumes that there is one ATE hooked up to one DUT in the testbed, and their ports are connected pairwise. They are defined in topologies/atedut_*.testbed with three variants: 2 ports, 4 ports, and 12 ports.

• The 2 port variant is able to run the vast majority of the control plane tests.
• The 4 port variant is required by some VRF based or data plane tests.
• The 12 port variant is required by the aggregate interface (static LAG and LACP) tests.

Setup: edit topologies/atedut_12.binding to specify the mapping from testbed topology to the actual hardware as well as the dial options.

Testing:

cd ./topologies/ate_tests/topology_test
go test . -testbed ../../atedut_12.testbed -binding ../../atedut_12.binding

❗ NOTE: when go test runs a test, the current working directory is set to the path of the test package, so the testbed and binding files are relative to the test package and not to the source root. It is recommended to just cd to the test package to be consistent.

⚠️ WARNING: the topology_test is derived from a similar test used at Google. The test code compiles but is not tested because we have not hooked up Google's testing environment to the open-sourced static binding. This is an early preview meant to demonstrate Ondatra API usage.

Path validation

The make validate_paths target will clone the public OpenConfig definitions and report Feature Profiles that have invalid OpenConfig paths.
