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

Great video and thanks for sharing. But I have a comment, in putting ip address in vlan, you’ve mention that it is for management only? as far as I know it should be a gateway of the client pc (ex.vlan10) in order to travel to different vlan or maybe the router itself(subinterface) is the gateway for 2 vlans.
Thanks and more power to you David.

thank you very much and may the god bless you and your family….
hi i wish information to VLAN if send in formation to me than you
thanks sir it was very simple to understand.
On the first slide “Any connection that carries traffic from more than 1 VLAN is called a trunk port” -> a VLAN port can be assigned to 2 VLANS (ip telephony + normal traffic) without being trunk port.
