FREE VIDEO: How to Configure VLAN s in the Cisco IOS

Recently, I created a short video that shows you how to configure and use VLAN s on a Cisco IOS Router & Switch. It is a step-by-step 15 minute video. It was originally published over at SearchNetworking.com. A virtual LAN (VLAN) is a broadcast domain created by switches. VLANs are a convenient way to connect ports from different switches and different buildings onto the same network and broadcast domain, preventing the need for a complex system of subnets.

In this video, you will learn how to configure a VLAN in this step-by-step, automated, 15-minute demo. I am a CCIE Cisco networking expert and I will walk you through the steps you’ll need to configure your routers and switches, set up and assign the trunk ports, and perform the necessary tests to get traffic moving across your VLAN successfully. You can view the configuration commands I used in the video at the bottom of this page.

Oh - if you would like to see an EXCELLENT video training course that covers all aspects of VLAN configuration, switch configuration, and prepares you for the CCNP, please check out the Train Signal Cisco CCNP Training Video Series - 642-812 BCMSN
