Configure Switching Features

Introduction

Welcome to the Configure Switching Features Practice Lab. In this module, you will be provided with the instructions and devices needed to develop your hands-on skills.

Learning Outcomes

In this module, you will complete the following exercises:

• Exercise 1 - Trunk Configuration Part 1
• Exercise 2 - VLAN Trunk Protocol
• Exercise 3 - Trunk Configuration Part 2
• Exercise 4 - Native VLAN Configuration
• Exercise 5 - Adding and Removing VLANs from a Trunk
• Exercise 6 - Configuring EtherChannel

After completing this lab, you will be able to:

• Create a trunk link and pass two VLANs through it
• Configure DTP functions
• Configure VTP to distribute VLAN database information from one switch to another
• Identify Native VLANs, their uses, and vulnerabilities
• Configure Native VLANs for secure connectivity
• Add and remove VLANs to a trunk
• Examine and configure layer 2 and layer 3 static etherchannel

Exam Objectives

The following exam objectives are covered in this lab:

• N10-007 3.2: Compare and contrast business continuity and disaster recovery concepts (Availability concepts, NIC teaming)
• N10-007 3.2: Compare and contrast business continuity and disaster recovery concepts (Availability concepts, Port aggregation)
• N10-007 4.6: Explain common mitigation techniques and their purposes (Change native VLAN)

Lab Duration

It will take approximately 1 hour to complete this lab.

Exercise 1 - Trunk Configuration Part 1

A trunk is a link, usually between two switches, that transmits frames belonging to two or more VLANs. It is because of trunks that you are able to distribute multiple VLANs throughout multiple switches.

Learning Outcomes

After completing this exercise, you will be able to:

• Create a trunk link and pass two VLANs through it
• Configure DTP functions

Exercise 2 - VLAN Trunk Protocol

VTP is a protocol that functions in a client-server model. One device, in this case, NYCORE1, will be configured as the server where all VLAN configurations are made. Client devices, in this case, NYACCESS1 receive the information about the VLANs, created and automatically create them in their own VLAN databases.

Learning Outcomes

After completing this exercise, you will be able to:

• Configure VTP to distribute VLAN database information from one switch to another

Exercise 3 - Trunk Configuration Part 2

In Exercise 1 you partially configured a trunk link between** NYCORE1** and NYACCESS1. The configuration was completed on the NYCORE1 side, however, not on the NYACCESS1 side. You configured VTP in Exercise 2 so that NYCORE1 will automatically share its VLANs with NYACCESS1.

Now that NYACCESS1 has the appropriate VLANs configured, you can finish the trunk configuration.

Learning Outcomes

After completing this exercise, you will be able to:

• Create a trunk link and pass two VLANs through it

Exercise 4 - Native VLAN Configuration

Frames that are placed on a trunk are tagged with the VLAN ID that they belong to. What happens if a frame without a tag is placed on a trunk link? The answer is, the frame is placed on the Native VLAN.

Each trunk is configured with a Native VLAN. If it is not configured properly, it could be a source of network vulnerabilities that attackers can take advantage of.

Learning Outcomes

After completing this exercise, you will be able to:

• Identify Native VLANs, their uses, and vulnerabilities
• Configure Native VLANs for secure connectivity

Exercise 5 - Adding and Removing VLANs from a Trunk

As a network evolves, new VLANs must be created to accommodate the needs of the network. As a result, these VLANs often have to be propagated to multiple switches. Sometimes, VLANs are removed from networks or renumbered.

Learning Outcomes

After completing this exercise, you will be able to:

• Add and remove VLANs to a trunk

Exercise 6 - Configuring EtherChannel

EtherChannel is a port link aggregation technology that enables you to bundle multiple switch interfaces together to act as a single aggregate link, increasing bandwidth with the added advantage of resiliency.

In this exercise, you will learn how to configure Layer 2 and Layer 3 static EtherChannel.

Learning Outcomes

After completing this exercise, you will be able to:

• Examine and configure layer 2 and layer 3 static etherchannel
