The Configure, Verify, and Troubleshoot VLANs module provides you with the instructions and Cisco hardware to develop your hands on skills in understanding, configuring and troubleshooting VLAN configurations on switches. This module includes the following activities:
- Understand the fundamentals of VLANs
- Create VLANs and assign them to specific ports
- Understand the Default VLAN and take steps to mitigate its vulnerabilities
- Configure a voice VLAN and verify the configuration
Exercise 1 - VLAN Creation and Management
VLANs are an important part of your network design and are an indispensable tool to make your network versatile and secure.
In this exercise you will review the fundamentals of VLAN creation and management, you will be introduced to extended VLANs, and you will re-examine best practices concerning the default VLAN that will improve security.
Exercise 2 - Creating a Voice VLAN
With the advent of what is known as network convergence, networks have been designed to accommodate various types of payloads including voice. Voice requires special consideration because of its nature as a payload and because of its sensitivity from both a quality of service as well as a privacy standpoint. As such, Cisco has developed a special type of VLAN that accommodates the needs of voice.
Modern voice and data networks only require one port per workstation as most phones have a network port into which a computer can be connected. This way, only one network port is necessary to equip a workstation with both a telephone and a computer. Transmitting voice and data over a single connection while at the same time maintaining quality of service and security demand VLAN mechanisms appropriate to accommodate such requirements.
