Configuring and validating devices with code instead of a keyboard. Articles tagged Network Automation cover Python tooling, model-driven interfaces and testing changes before they ship.
SD-WAN Manager (vManage) exposes a REST API for the entire Catalyst SD-WAN fabric. This article walks the API's shape for network engineers: monitoring the fabric, pulling tunnel health, and automating policy changes.
Catalyst Center exposes everything through a REST API: inventory, intent, and assurance data at scale. This article explains the API model and the categories of endpoint, with documentation-style request and response examples.
A script that ignores HTTP response codes eventually lies about success. This covers the codes that matter for RESTCONF, Catalyst Center, and SD-WAN Manager APIs, what 200, 404, and 500 tell you, and how to act on each.
YANG is the schema language behind NETCONF, RESTCONF, and gNMI. This post explains data models for network engineers: what a model defines, the difference between native and OpenConfig models, and how to actually explore one.
RESTCONF exposes the same YANG models as NETCONF over ordinary HTTPS: GET to read, PATCH to modify, PUT to replace, DELETE to remove. If you can use curl or Python requests, you can drive a Catalyst 8000v with it.
NETCONF replaces screen-scraping with structured XML over SSH against YANG models. This walkthrough drives Cisco IOS XE with ncclient from a real Linux automation host, from first hello to config change.
EEM runs on the router itself, watching for events and acting on them with no external server to depend on. This article builds three EEM applets on Cisco IOS XE for config automation, troubleshooting, and data collection, and fires all three for real.
RESTCONF, Catalyst Center, and SD-WAN Manager APIs are doors into your infrastructure. Learn tokens, TLS, and least privilege for network APIs, framed for network engineers rather than web developers.
CCNA v1.1 added AI and machine learning to the blueprint. This post covers the learning types, the predictive versus generative split, real network operations use cases, and the honest limits, framed for the exam and the job.
Ansible, Puppet, Chef, and Terraform compared on the axes that separate them, then Ansible runs for real against three live Cisco IOS XE routers, including the idempotency gotcha that bites everyone the first time.
REST is how your scripts talk to a network controller. This guide covers HTTP verbs, status codes, authentication, and JSON structure, grounded in real requests against a live Cisco Modeling Labs controller.
Control plane vs data plane, northbound and southbound APIs, and the overlay, underlay, and fabric vocabulary, mapped to the Cisco products you will meet. CCNA domain 6 concepts with the routing and switching you already know kept at the center.
