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

98 Replies

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.

    i like to ask if pc 1 from vlan 10 have a ip address 142.3.1.1 while pc 2 have from vlan 20 have a ip address of 142.41.1.21 ,from what i know all i need to do is change the ip address on the router itself .but for my router have only 2 interface port and one of interface port FA 0/1 is connect into my vlan switch while the other FA 0/0 is connected into my firewall .right now from my router i can ping to my pc2 but cant to my pc 1 ,i like to ask is it my subnet mask got a problem as i using 255.255.255.240 for both pc1 and pc 2 or could it be the configuration got a problem ???as i believe is my subnet mask got a problem .i can’t seem get the both PC to talk to each other
