FRINX UniConfig introduction

The purpose of UniConfig is to manage configuration state and to retrieve operational state of physical and virtual networking devices. UniConfig provides a single API for many different devices in the network. UniConfig can be run as an application on bare metal in a VM or in a container, standalone or as part of our automation solution FRINX Machine. UniConfig has a built-in data store that can be run in memory or with an external database.

UniConfig key feature overview

  • Retrieves and stores current startup and running configuration from mounted network devices

  • Pushes configuration data to devices via NETCONF or CLI

  • Allows for diffs to be built between actual and intended execution of atomic configuration changes

  • Retrieves operational data from devices via NETCONF or CLI

  • Provides subtree filtering capabilities in NETCONF

  • Transactions can be managed on one or multiple devices

  • Offers the ability to do a dry-commit to evaluate the functionality of a configuration before it is executed on devices

  • Provides snapshots of previous configurations if you need to rollback

  • Translates between CLI, native model and standard data models (i.e. OpenConfig) via our open-source device library (

  • A ‘Lazy CLI’ feature to suspend and resume connections without having to maintain keepalives

  • Can read and store proprietary data models from network devices that follow the YANG data model

  • Data export and import via blacklist and whitelist functions

  • Provides templates for device configuration

  • Supports PostgreSQL as an external database

  • Support for YANG 1.1 and Tail-f actions

  • Subscription to NETCONF notifications via web sockets

  • Support for 3-phase commit by using NETCONF confirmed-commit

  • High availability

  • The ability to log specific devices as needed

  • Can execute commands in parallel on multiple devices

  • Choose between NETCONF or RESTCONF to connect to devices

  • The UniConfig client allows for simple, full-service access to the UniConfig features

  • Python microservices are used to integrate with the FRINX machine

  • The UniConfig UI allows users to interact with the network controller through a web-based user interface

UniConfig enables users to communicate with their network infrastructure via four options:

  1. Execute & Read API - Unstructured data via SSH and Telnet

  2. OpenConfig API – Translation provided by our open source device library

  3. UniConfig Native API – Direct access to vendor specific YANG data models that are native to the connected devices as well as UniConfig functions (i.e. diff, commit, snapshots, etc.)

  4. UniConfig Native CLI API – Programmatic access to the CLI without the need for translation units (experimental)

Execute & Read capable API: Like Ansible, TCL Scripting or similar products strings can be passed and received through SSH or Telnet via REST API. UniConfig provides the authentication and transportation of data without interpreting it.

OpenConfig API: An API that is translated into device specific CLI or YANG data models. The installation of “translation units” on devices is required. FRINX provides an open source library of devices from a variety of network vendors. The open source framework allows anyone to contribute or consume the contents of the expanding list of supported network devices.

UniConfig Native API: A vendor specific YANG data models are absorbed by UniConfig to allow configuration of mounted devices. UniConfig maps vendor specific “native” models into it’s data store to provide stateful configuration capabilities to applications and users.

UniConfig Native CLI API: Allows for interaction with a devices CLI is programmatic through the API without the use of ‘translation units’, only a schema file is needed. (This option is currently experimental, contact FRINX for more information.)

UniConfig solution

UniConfig in a Docker container

Download and activate FRINX UniConfig

Enter the following commands to download, activate and start UniConfig in a Docker container:

docker pull frinx/uniconfig:4.2.8.frinx
docker run -it --hostname uniconfig --name uniconfig -p 8181:8181 frinx/uniconfig:4.2.8.frinx -l $TOKEN


Replace [frinx-licence-secret-token] with your unique token. The token is unique to your user account on and cannot be shared with other users. It can be found here. (you need to be logged in to view your token).

Stop the container

To stop the container type:

docker stop uniconfig
