What you will learn

Networking, port by port

The skills behind every network job, taught by building and breaking things. Each one has a lab.

Labs

The same config, two vendors

Every lab starts from a topology and a goal. You build it, then compare how each vendor's CLI does the same job. Below is the access-port VLAN setup from lab one.

vlan 10
    name STAFF

How it works

Every topic has the same three parts

The format stays the same from lesson to lesson, so you always know what to do next.

Concept video

A short explanation with the diagram drawn as I talk. Usually 5 to 10 minutes.

Lab

A screen-recorded walkthrough plus the commands as copyable text, so you can repeat it yourself.

Quiz

Practice questions on that topic, written in the style of the exam.
