About this Course

This course is several hours in length and will cover Layer 2 switching in detail. I will explain the Technology and media access control method for Ethernet networks, network segmentation, switching concepts and the operation of Cisco switches.

DISCLAIMER:Please note that the simulators/emulators used in this course are not part of the course. It is the students responsibility to have these to practice with. The Cisco Packet Tracer and/or VIRAL (Virtual Internet Routing Lab) are Cisco proprietary software and can only be obtained through Cisco. It is up to each student to obtain the simulator/emulator of their choice to study along with this course. 

Students will get a thorough understanding of switching and how we would implement it in a real world environment.

We will discuss the following concepts switching services and rules we should follow when segmenting networks. We will also compare bridging vs. LAN switching focusing in great detail on the Spanning-tree protocol. We will look at the switch Functions at layer two, such as how a switch learns about the nodes on the network and how it makes its decisions to forward the information and most definitely how to secure our ports on the switches.

Once get an understanding of how switches work and their administrative configurations we will then go into explain and creating vlans and inter-vlan connectivity and what would be the benefits of using VLANs on our network. You will learn the different port types and encapsulation methods we use when using vlans, and will fully understand the difference between trunking a port and the VTP protocol.

This is a lecture based course using the Touch-IT Technology Smart board, which will make learning very interactive and engaging. Hands on labs will be used to drill down the concepts learned in each lecture using Cisco's Packet Tracer.

My method will make you feel like you are sitting in a classroom environment and give the most needed hands on experience!

Handouts will be available to facilitate learning and practice.

This course will help the student become familiar with layer 2 switching and vlans and how to implement them in your environment…but it will also help in preparing for any networking certification or Computer Science Degree; not to mention the fact that for those already in the field, it will further improve routing decisions in their particular networks.

Who is the target audience?

  • This course is intended for anyone that is preparing for a network certification or Computer Science Degree. However, it does go beyond that, it is also intended for those Networking and/or IT Professionals that are already in the field and need a better understanding of switching
Basic knowledge
  • Students should have an understanding of basic networking
  • The Cisco Packet Tracer or similar simulator
  • The desire to learn and apply the knowledge obtained in a testing environment or real world scenario
What you will learn
  • Once you finish my course, you will have a strong grasp on the switching concepts and the methods to use in different networking environments. You will be able to configure the cisco switch with all its administrative tasks, STP, RSTP, VTP and switch port security. You will learn how to improve the performance of the switches by turning off services on certain ports so information can start transmitting much quicker. The understanding of Layer2 concepts is an essential element for any Networking and/or IT Professional. This course will prepare the student for any networking certification such as N+, CCNA, MCSE to include any Computer Science Degree
  • Mastering this knowledge will make the student, Networking and/or IT Professional a much more valuable asset in any IT environment

Layer 2 Switching
  • Introduction to layer 2 switching  

    This Lesson is an overview of the subjects that you will be learning in this course.

  • How the switch populates its MAC address table  

    In this lesson I will demonstrate using the Packet Tracer how exactly, a switch learns MAC addresses from the nodes that are connected to it.

  • Switching Loops at layer 2  

    This lesson will explain how having redundant switch connections you could have loops at layer 2 and the protocol that will help you prevent those loops.

  • Port Security  

    This lesson will show you how to configure security on individual or a range of ports, to only allow a certain number of mac address on those ports.

Configuring Catalyst Switches
  • Basic Administration Configuration  

    This lesson will demonstrate some of the basic configurations that you would configure on a switch.

  • Advanced Administration Configuration  

    This lesson will demonstrate some of the advanced configurations that you would configure on a switch.

  • Verifying Cisco Catalyst Switches  

    In this lesson you will learn various commands, that you could use to verify your configurations on your Cisco Catalyst Switches.

  • Backing up Switch configurations  

    In this lesson you will learn to back up not only your configuration but your IOS as well to a TFTP server.

Enhanced Switched Techonologies
  • The Spanning-Tree Protocol  

    This lesson will explain to you how the Spanning-Tree Protocol works, specifically when its deciding which switch will be the root bridge and wich switch will have a blocked port to prevent the BPDU's from fowarding out a specific port.

  • Types of Spanning-Tree  

    In this lesson you will briefly learn that there are different types of STP that you could configure on your Cisco Catalyst Switch.

  • Per-vlan Spanning-Tree  

    This lesson will explain how you can have Per-Vlan Spanning-Tree, depending on the STP version you use.

  • Modifying the Switch Bridge ID  
Manipulating Spanning-Tree Protocol
  • Using the Portfast command  

    In this lesson you will learn how to turn off STP, using the portfast command. This will allow the port to quickly turn to a designated fowarding state.

  • Using the BPDUGUARD command  

    In this lesson you will learn how to guard your ports from someone accidentally connecting an internetworking device to them. Since, you turned of STP we must implement a command that would prevent BPDU from propogating out of unwanted ports.

  • Verifying Spanning-Tree Protocol  

    This is a very brief lesson on how to verify that STP is configured according to your needs and how to use the CDP command aswell.

Vlan Basics
  • Broadcast Control using Vlans  

    In this lesson, I will explain how creating vlans, will deacrease the amount broadcast within a broadcast domain.

  • Security using Vlans  

    In this lesson, I will explain how creating vlans enchances your security, since the router is the one that determines the path the packet will take.

  • Flexibility and Scalability  

    In this lesson I will explain to you, how vlans can help you make your network more flexible and scalable to work with.

Identifying Vlans
  • Switchport modes  

    In this lesson I will explain the importance of switchport modes and how to configure them.

  • Frame Tagging  

    In this lesson I will explain how the switch knows where to send each vlan to there correct destination.

  • Vlan Identification Method  

    In this lesson you I will explain the two methods used for Vlan Identification.

Routing Between Vlans
  • Do we need routers?  

    In this lesson I will explain the need to still have routers in our network.

  • Creating Vlans  

    In this lesson I will show you how easy it is to create a vlan.

  • Naming and assigning Vlans  

    In this lesson I will show you how to assign a vlan to a range of ports.

  • Configuring Trunk Ports  

    In this lesson you will finish of from the previous lab in assinging the vlans, configuring port security and so forth. We then are going discuss the trunking of ports and why they are needed.

  • Changing the Native Vlans  

    In this lesson I will show you how to change your Native Vlan from Vlan 1 to some other number and assign the ports to that vlan. I will also discuss the importance of keeping the Native Vlan name consistent accross your switch network.

Router Configuration
  • Inter-Vlan configurations  

    In this lesson you will learn how to configure inter-vlan communication, using sub-interfaces and the correct encapsulation.

Virtual Trunking Protocol
  • Defining VTP  

    In this lesson I will explain what VTP is, what it is used for and how to status VTP.

Summary of Layer 2 Switching
  • The importance of creating a secure, redundant and fast switched network  

    This lesson is simply an overview of everything we covered, stressing to you what points to focus on when you study for the CCNA.
