Decision gist · record as of 2026-08-14
Yes, if you are working with Cisco pyATS or need to automate NETCONF/GNMI interactions with network devices. The package is actively maintained, has no known vulnerabilities, and integrates well with the pyATS ecosystem. Install it only if you have NETCONF or gRPC-capable devices to connect to; it is not useful as a standalone utility.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires network connectivity to a NETCONF-enabled device; paramiko and ncclient must be able to establish SSH connections.
- Low friction installation with a pure-Python wheel.
- Active maintenance with a release within the last week.

What it is and what it does
yang.connector is a NETCONF and gRPC/GNMI client library for Cisco's pyATS test automation framework. It abstracts the complexity of connecting to network devices that expose YANG data models, allowing you to send configuration commands, retrieve operational state, and automate network testing workflows. The package wraps lower-level libraries like ncclient (for NETCONF) and grpcio (for gRPC) to provide a unified interface aligned with pyATS conventions.
The library is intended for network engineers and test automation developers who need to programmatically interact with Cisco devices or other NETCONF/GNMI-capable equipment. It handles the protocol-level details of SSH tunneling, XML parsing (via lxml), and gRPC serialization (via protobuf), so you focus on the test logic rather than connection management.
Use it for
- Automate NETCONF configuration changes on network devices as part of a pyATS test suite
- Retrieve operational state and configuration snapshots from YANG-modeled devices for validation
- Build gRPC/GNMI clients to interact with modern Cisco devices supporting telemetry
- Integrate network device connectivity into CI/CD pipelines for infrastructure testing
- Compare before-and-after configurations during network automation workflows

Before you install
Low friction installation with a pure-Python wheel. Active maintenance with a release within the last week. Five runtime dependencies (paramiko, lxml, ncclient, grpcio, protobuf) are all established libraries, though grpcio and protobuf add some weight to the dependency tree.
Requires network connectivity to a NETCONF-enabled device; paramiko and ncclient must be able to establish SSH connections.
