Overview
Your complete guide to Running the network like a pro
Monitoring with SNMP, modern telemetry and logs, quality of service for voice and video, network automation with Python, Ansible and a source of truth, then a full branch project you build and fail-test.
Non-technical and technical learners alike. Every part opens two ways in: a plain path built on an analogy for someone starting from zero, and a detailed path for someone who knows the basics and wants depth.
An animation, then what you need before you start, then the idea with code you run, then a worked example, then review cards and "test your understanding" questions.
Do not leave a part before you can answer its questions without guessing. Reading alone proves nothing.

A look at Running the network like a pro
You see the network first, then decide who goes first when it is busy, then let the machine write the settings for you, then pull it all together in a branch project.
| Part | Topic | You learn |
|---|---|---|
| 1 | Monitoring the network: SNMP, logs and flows | What to measure, SNMPv3 polling and traps, syslog levels and NTP, NetFlow and IPFIX, streaming telemetry, baselines and the 95th percentile, sensible alerting |
| 2 | Quality of service: voice first when the link is busy | When you need QoS, latency, jitter and loss, classifying, marking, DSCP and EF, trust boundaries, the LLQ priority queue, policing versus shaping, sizing voice bandwidth |
| 3 | Network automation: a source of truth, templates and checks before change | A source of truth, templates, desired versus running, idempotency, NETCONF, RESTCONF and YANG, Ansible and Netmiko, pre and post checks, Git and review, containerlab |
| 4 | Project: a branch with no single point of failure | A design with no single point of failure, the build order, failing things on purpose, documenting the design, a portfolio on GitHub |
