Switches and Routers: A Comprehensive Hands-On Introduction

You Will Learn How To

Build and design scalable networks
Compare the operational benefits of Ethernet and WLAN
Deploy switches using Spanning Tree and VLANs
Employ a variety of LAN interconnection techniques
Determine the optimum routing protocol for various internetworking environments
Integrate network management and security

Course Benefits

Switches and routers are the critical building blocks of a successful internetwork infrastructure. In this course, you gain the essential knowledge required to deploy and use switches and routers in IP networks. Through a combination of written and hands-on exercises, you acquire the skills to effectively select and deploy appropriate internetworking technologies.

Who Should Attend

Network managers, technicians, engineers and consultants involved in designing, implementing or managing networks. Knowledge of computer networking principles at the level of Course 450, "Networking Comprehensive Introduction", is assumed.

Hands-On Training

Hands-on exercises provide you with experience deploying routers and switches. Exercises include:

Setting up a new switch and router from initial factory configuration
Building and optimising a switched LAN
Network testing using ping and traceroute
Implementing an IP address design
Exposing switch and router security weaknesses
Deploying and optimising VLANs and Spanning Tree
Comparing RIPv1 and RIPv2 with a protocol analyser
