Junos Snapshot Administrator (JSNAP)

Junos Snapshot Administrator captures and audits the runtime

environment of network devices running Junos OS, automating

network state verification by capturing and validating the status of a

device. It is used to take pre- and post-snapshots of the

environment, then compare them based on test cases provided. It is

also used to audit a device’s runtime environment against

predefined criteria. JSNAP is the Stylesheet Language Alternative

Syntax (SLAX) version of the tool.

JSNAP using Python (JSNAPy)

JSNAPy is the Python version of the JSNAP tool described above.

JavaScript Object Notation (JSON)

JSON is a popular data exchange format which has become a

standard for simple and lightweight communication between

devices and applications. To enrich native support in several

programming languages, Junos OS operational commands can emit

output in JSON format. Junos OS configuration input can also be

provided in JSON format.

Junos Telemetry Interface

The Junos Telemetry Interface (JTI) is a high-frequency telemetry

export function available on Juniper networking platforms to

optimize network performance and fault management.

Junos User Interface Scripting Environment

The Junos User Interface Scripting Environment (JUISE) is a set of

tools that allows the development and testing of SLAX scripts

targeting devices running Junos OS. Users can develop scripts in

their own desktop environment, performing the necessary code,

test, and debug cycles in a more familiar setting. Tools for

developers are available, including a debugger, a profiler, a call- flow

tracing mechanism, and trace files.

Jxmlease

Jxmlease is a Python module that converts XML to intelligent

Python data structures, and vice versa.

NETCONF

NETCONF is a protocol defined by the IETF for installing,

manipulating, and deleting network device configurations.

NETCONF Libraries

NETCONF libraries support XML-based data encoding, SSH

transport, and RPC support using different languages including

Python, Ruby, PHP, Java, Go, and Perl.

OpenConfig

OpenConfig is an informal working group of network operators that

is focused on compiling a consistent set of vendor-neutral data

models (written in YANG) based on actual operational needs from

use cases and requirements from multiple network operators.

PyEZ

Junos PyEZ is a Python “micro-framework” used to remotely

manage or automate a device running Junos OS.

Python

With native support for Python in Junos OS, users can develop and

execute operational, event, and configuration commit scripts using

Python.

Representational State Transfer (REST) API

The Junos OS REST API is an interface that enables users to

securely connect to Junos OS devices and execute remote

procedure calls. Using the REST API Explorer GUI, users can

conveniently experiment with any REST API and explore a variety

of formatting and display options, including JavaScript Object

Notation (JSON). REST uses HTTP as its application- layer protocol.

RubyEZ

The RubyEZ framework allows users to automate management of

Junos OS devices without requiring specific Junos XML knowledge.

Stylesheet Language Alternative Syntax

SLAX is a language for writing Junos OS Op Scripts, Event Scripts,

Commit Scripts, and SNMP Scripts.

Third-Party Platforms and Tools

Ansible, SaltStack, Chef, and Puppet are IT provisioning tools that

also bring the networking environment closer to the concept of

continuous delivery. Junos OS automation supports all of these

tools.

• Ansible: A free software platform that combines multinode

software deployment, ad hoc task execution, and configuration

management; Ansible works in proxy mode without requiring

an on-box agent.

• SaltStack: A tool that allows users to remotely configure a

number of devices simultaneously, with a single command;

SaltStack works in proxy mode without requiring an on-box

agent.

• Puppet: An open-source configuration management tool that

runs UNIX-like systems or Microsoft Windows and includes its

own declarative language to describe system configuration.

• Chef: An IT provisioning tool that integrates with cloud- based

platforms to automate the process of provisioning, configuring,

and maintaining new servers.
