Packet Tracer NetSim/Walkthrough Labs
NetSim/Walkthroughs labs are similar to guided labs available elsewhere. They provide structured, step-by-step learning experiences that help learners explore new or unfamiliar concepts.
These walkthroughs give students the chance to get hands-on practice and build confidence through direct keyboard interaction.
Packet Tracer NetSim/Walkthrough
Switch Walkthrough
Difficulty: Easy · Approx. 20 min
Ever wonder how a switch “remembers” who’s who on the network? In this lab, we follow the frames as they enter the switch, watch the MAC table come alive, and break down learning, flooding, and forwarding in a simple, visual way. Perfect for beginners who want to finally see Layer 2 in action.
