How I became a Networking Enthusiast

I’ve always been curious about networks. I remember opening up an old Linksys Router and discovering the physical circuit, the processor and integrated memory.

But my official networking life didn’t start until my coworker taught me the basics of routing. The first thing I learned was how to log in and enter commands within the command line. The second was CRC errors. These small lessons peaked my interest and by the following week I was digging in and researching how the devices worked. The first Cisco device I had the pleasure to meet was a Catalyst 6500.Cisco Catalyst 6500

I had no idea what I was doing, but I was eager to learn. Software verses firmware, “.bin”’ extensions, encapsulation, connections from LAN to WAN, wiring. The more I researched, the more I liked it and realized this was what I really wanted to do. Read More »

Cisco Instant Access: What Is It?

What is Cisco Instant Access?

Cisco Instant Access is a concept that was launched at Cisco Live Orlando last year. For those of you familiar with the Nexus product line, think Fabric Extender (FEX). The first customers are starting to implement this concept now. The whole point of Instant Access is explained with the picture below.

To the left is the traditional network with multiple access switches located in closets, uplinked to the distribution layer or straight to the core in a collapsed core design. Every access switch is a point of management which needs configuration, software maintenance and feature compatibility with other access switches. Read More »

How does Cisco Backbone Switching help address BYOD, Mobility and Security Needs?

November 25, 2013 at 5:05 am PST

Cisco will host a live backbone switching webcast on Wed Dec 4, 2013 to discuss BYOD, mobility, security and how Cisco backbone switching addresses these customer needs. This is the second webcast in the Cisco switching webcast series. You can view the first one, Cisco access switching webcast, at any time as it is now an on-demand video.

This backbone switching webcast comes at a critical time, as BYOD and mobility are creating major impact to the workplace.  According to a recent study on BYOD and mobility,

  • 75% of employees think that the IT department should help secure personal devices used at work;
  • 63% of IT pros say the biggest network issue will be the increased bandwidth requirements;
  • 39% of them say that network latency is a problem because of mobile devices;
  • And 39% of them have seen serious issues tied to network performance as a result.

Cisco Catalyst Instant Access Dramatically Simplifies Your Network

August 24, 2013 at 6:30 am PST

There are a lot of great technologies that have outstanding business benefits but are not widely deployed. For example, 802.1X for wired networks can determine appropriate network access based on user identity and additional contextual information. The technology is already built into the network to help customers improve their network security. If you ask your peers in the industry, however, you may hear that many of them have not turned on 802.1X on their switching network.  Why? Depending on who you ask, you might get different answers from different people. But one common response is that IT staff is too busy with so many burning issues on their network so they don’t have time for something like 802.1X. It’s not just about this technology. They never have enough time to do testing, troubleshooting and configuration changes. That’s why any solutions that can help simplify and streamline networks and IT operations will go a long way.
