junos-eznc

What it is and what it does

Junos PyEZ abstracts the complexity of Junos device management by providing a Python interface to NETCONF, the standard network configuration protocol. It retrieves device facts (serial number, software version, model), operational state as structured tables and views, and configuration data without requiring users to write or parse Junos XML directly. The library is designed for two audiences: network engineers who want to use Python as an interactive shell for common automation tasks like conditional testing and templating, and software developers who need an extensible foundation for integrating Junos automation into larger IT systems.

The package depends on ncclient for NETCONF communication, paramiko for SSH, lxml for XML processing, and several utilities like Jinja2 for templating and PyYAML for configuration handling. It supports modern Python versions and is actively maintained. The library provides utilities for common operations such as secure file copy, software updates, and configuration changes in both unstructured and structured formats.

Use it for:

• Retrieve device inventory facts (model, serial number, software version) from multiple Junos devices in a loop for asset tracking.
• Automate configuration changes across a fleet of firewalls or routers using Jinja2 templates and structured configuration APIs.
• Build a network monitoring dashboard that periodically queries operational state (interface statistics, routing tables) from Junos devices.
• Perform conditional network tasks—e.g., update software only on devices matching certain criteria—using Python control flow.
• Integrate Junos device management into a larger DevOps or orchestration pipeline without writing custom XML parsers.

Worth the install?

AI-flagged interpretation of the facts on this page — verify before relying

Junos PyEZ is a Python library for remotely managing and automating Junos devices via NETCONF, enabling both interactive scripting and programmatic control without requiring deep Junos XML API knowledge.

Yes. Junos PyEZ is actively maintained, has no known vulnerabilities, uses permissive licensing, and offers low installation friction. It is well-suited for teams managing Junos infrastructure who want to automate tasks without deep XML API expertise. Install it if you need to programmatically manage Junos devices; skip it if you have no Junos devices or prefer CLI-only management.

Install

junos-eznc on PyPI

pip install junos-eznc

uv add junos-eznc

poetry add junos-eznc

Installing junos-eznc

Before you install

Low friction installation via pip; the package is actively maintained with a recent release and depends on well-established libraries like ncclient, lxml, and paramiko. Requires Python >=3.8 and ncclient version 0.6.15 or later.

License in practice

Licensed under Apache 2.0 (permissive), allowing free use, modification, and distribution in both open-source and commercial projects with minimal restrictions.

Quickstart

pip install junos-eznc

from jnpr.junos import Device

with Device(host='device_ip', user='admin', password='pass') as dev:
    print(dev.facts)

Requires network connectivity to a Junos device; on macOS Mojave and higher, SSH keys must be in RSA format, not OPENSSH format.

Verify before relying

• Whether the package works with Junos Evolved devices as claimed in the description.
• Performance characteristics when managing large numbers of devices or complex configurations.
• Compatibility with specific Junos product families beyond the SRX examples shown.
