What is Cisco Telepresence & an amazing video demo from John Chambers!

Leave a reply

Recently, I published an article over at the Petri Knowledgbase, entitled “What is Cisco Telepresence and what does it take?“. In that article, I covered why you should care about telepresence, what it can do for you, and what you need to do to prepare your network to support telepresence. Believe me, there is a lot more to telepresence than just “video conferencing”.

A friend passed the following YouTube video along to me. In this video, telepresence looks more like the “holodeck” from Star Trek. Check it out, it is truly amazing!

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

Network summarization — Supernetting and wildcard masks

9 Replies

Supernetting was created as a way to solve the problem of routing tables growing beyond our current ability to manage the exhaustion of Class B network address space. Much like one area code represents an aggregation of telephone numbers in an area, supernetting allows one routing table entry to represent an aggregation of networks. If you need to enter a static route to several subnetted networks, you can use network summarization to reference them all in one route. Just the same, you need to understand how to read routes received from other providers. You must also know how to create an access list that references these multiple networks in a single summarized statement. In this tip, you’ll learn more about the IP addressing-related topics of network summarization, supernetting and wildcard masks.
