A Look Back at 2015 at AJSNetworking.com

January 1, 2016 at 3:51 pm


Thank you to all of the faithful readers here at AJSNetworking.com for an incredible year.


2015 in Review

Just wanted to recap some fun facts as we get ready for an even better 2016 here at the blog!

  • I finally surpassed the 100,000 view mark. I was obviously super excited about this. I cannot wait to help even more around the world this year.
  • The busiest day of the year for the blog was an easy one to see – November 21st, 2015. This was thanks to a massive announcement from none other than Cisco Systems. All of the CCIE Written Exams changed at once. 🙂 I posted about it here, and this was the most popular post of the year – http://www.ajsnetworking.com/all-ccie-written-exams-changing/
  • I created only 125 posts in 2015. I was really disappointed by this number and will crush it in 2016.
  • I was thrilled to see that the total site article archive has grown to 318 posts.
  • What was the second most popular post? Well, I think this headline grabbed a lot of attention. 🙂 I am a CCNA Data Center Bad Ass!
  • Where did most of my traffic come from? Facebook. My fan page there Anthony Sequeira – Trainer gets a lot of traction around the world. Especially in the super awesome country of India.
  • You can also find me active on Twitter, LinkedIn, and Google+.
  • A surprising big time referral site was techexams.net – I checked it out briefly today and it looks pretty cool – I will be sure to register over there and give it a deeper look.
  • The top countries that enjoyed my site were the United States, UK, and India. Three places I love!
  •  The top contributors here were Ian, Pieterjan Denys, Mark, John, and Arindam Kar. Check your email guys as I sent correspondence today. 🙂

Thank you once again for an incredible year here – and you are going to be AMAZED at what 2016 brings!

Learning Product Review – Cisco Learning Labs for CCNP SWITCH v2.0

December 31, 2015 at 12:24 am

I was very excited to check out the Cisco Learning Labs for CCNP SWITCH v2.0 50-hour 180-day Labs. So many students are looking for SWITCH practice since GNS3 falls short here (in my opinion) and sometimes we do not have access to the horsepower required for Cisco VIRL. Or more accurately for me, I do not feel like making my VPN connection to my central VIRL box. 🙂

Lab Product Overview:

So here is the premise – for a price tag of $85 (at this time), we get 50 hours of access (over a maximum of 180 days) to the routers and switches we need to practice for SWITCH. We also get plenty of lab exercises to follow if we are not feeling creative enough to create our own. If my math is correct – this is $1.70 per hour of lab time. That is a screaming deal. The rack rental vendor I sometimes use is $10 for 3 hours. I thought that was a deal before this came along!

Purchasing the Labs:

The purchase was painless, although my password was not synced in the lab site to the Cisco.com site. I took care of this with a simple password reset procedure that was available. To purchase, just use this link – Cisco Learning Labs for CCNP SWITCH v2.0 50-hour 180-day Labs. For some reason the price shows as $100 from that link, but I believe you get a discount once you log in.

The Lab Experience:

Logging in provides a friendly interface that shows the labs and provides information on how much time I have remaining.

Lab Interface

NOTE: The picture above is not showing all of the many labs that are available…that was cut off.

Choosing Start Lab brings you to a topology map complete with clickable router and switch images. Click on one of these and a terminal window appears ready for you to follow the lab steps that are also provided.

The Lab

I was thrilled to see that I could not tell this equipment from live gear. In fact, I had no idea what I was dealing with from a technology standpoint. The devices sure seemed “real”, which is exactly what you want in your practice lab. Out of intense curiosity I ran a show version to learn that this is indeed powered by virtual images (Cisco IOS on UNIX for the device I checked).


I would be sure to check the requirements for these labs, of course. I was on a Mac and tested them in Safari and Google Chrome. They worked flawlessly in each browser. Just be sure you are on equipment they support and obviously your Internet connection is stable. Also, I would recommend you have a printer handy. Even though your instructions pop out, I am guessing that freshers would want to print out instructions to go over them very carefully as they sit at their command line windows.

Enjoy this incredible learning opportunity at an incredible price tag! Bravo Cisco!

How I Will Crush My 2016 Goals!

December 29, 2015 at 11:19 pm


Goals, Goals, and More Goals

I cannot recall ever being as excited for a New Year. It certainly is not like the last one was bad, I am just super excited for what is to come. Are you like me and looking to crush some goals in 2016? Here are some notes on my planning and conquering…

A Goal Reaching Head Start

There was no way I was going to wait until Jan 1, 2016 to begin making progress on some of my goals. Hey, some of them are just too damn difficult without a head start. For example, one of my goals is to run a half marathon. OK, OK, it is to jog a half marathon, but still, this was something I was absolutely too scared to try and start on the first of the new year. So I started running and tracking these runs in October, gearing up for the actual half marathon in 2016.

What Do I Really Want to Make a Goal?

I tend to leap headfirst at ideas and then try and achieve them. Sadly, I do this without a lot of thought. I just get really excited to try new stuff or learn new skills. In preparation for next year, I am really being careful about what I set out to achieve. I am focusing on the WHY I want to do things more than ever. To go back to the half marathon example, I realized there was a ton of reasons WHY I wanted to try and accomplish it. Weight loss, increased stamina, increased energy, they all added up to a big resounding GO FOR IT! Other goal ideas got scratched. Maybe some other year they would make more sense…


Why do I love my iPhone so much? That is simple – one word – TRACKING. I want to be a safer driver, the Automatic app tracks that. I want to run a half marathon, the RunKeeper app tracks that. I need to drink more water, WaterMinder tracks that…you get the idea. Most people never accomplish New Year’s Resolutions – only about 8% make it. Why is this? One big reason is they never track their progress throughout the year.

What are your goals for 2016? What are you doing to make sure you accomplish them? Let me know in the comments area below!

Subnetting – What Mask to Use

December 28, 2015 at 10:13 pm

SPeed Subnetting


Remember, it is totally worth repeating in this series of posts on subnetting – while practicing just how fast you can ace subnetting questions in the certification environment is always worthwhile and fun, you do want to make sure you understand exactly why you are going through the exercise to being with. You also want to be sure you understand how subnetting fundamentally works. This is often referred to as subnetting “longhand”. This is why a course like the CBT Nuggets IPv4 Subnetting – The Ultimate Guide is so critical.

ICND1 Sample Subnetting Question:

Your co-worker has decided upon use of the address space for a section of your network. This section requires 14 subnets. What subnet mask will you recommend?

Step 1: I reference the Powers of Two chart I created on my scratch paper when I encountered the first question. The formula for the number of subnets you can create based on subnet bits is 2 ^ S where S is the number of subnet bits borrowed. From the chart I see if we “borrow” 4 bits we can create 16 subnets. This is two more than we need in this scenario, but that is great as it will allow for future expansion with ease.

2^7=128  |  2^6=64  |  2^5=32  |  2^4=16  |  2^3=8  |  2^2-=4 | 2  ^1=2  |  2^0=1

Step 2: Borrowing 4 bits beyond the Class B boundary results in 255.255.128+64+32+16 = 240. Our mask is
