Following module IR.1101 (Networks Fundamentals), this module is dedicated to technologies and protocols required to conceive and implement a local switched network, including an introduction to wireless local networks.

Learning Objectives

Regarding skills, the goal of this module is to understand the ways to interconnect switches together, and their setup to provide network access to users of the local area network.
It also teaches how to integrate wireless peripherals into a local area network.

Concepts being exposed in this module are :

  • related to specificities of switched local area networks (based on Ethernet).


  • Ethernet switching
  • Virtual local area networks (VLAN)
  • Redundancy (Spanning Tree)
  • Wireless local area networks (WiFi)

The acquired know-how at the end of this module are :

  • being able to recognise a well conceived local area network, and choose the appropriate equipments to implement the network specifications for a mid-size enterprise ;
  • know how to configure, manage and repair virtual LANs and trunks ;
  • know how to use the STP protocol to avoid creating loops in the network ;
  • being able to identify the components (norms, devices) required to setup a wireless infrastructure.

Teaching method

This module is taught in traditionnal lectures in front of students (not based on e-learning).
It is partly based on the content of the Cisco Academy related to LAN switching and wireless (part of Cisco CCNA certification).
The class will focus mainly on principles and protocols, more than on specific Cisco implementation (IOS). It is still possible, for curious students, to study these Cisco specificities by reading the on-line class available on Moodle as a complement (not required for the exam).
