What's in my toolbag – Update 1 – Fluke LinkSprinter 200

LinkSprinter_200_LG_0 (1) A few years back some of us wrote on a common theme around our tools and tool-bags.  These posts turned out to be quite popular and informative to many in the community, including ourselves.  Since the original post back in 2011, I have added a few new toys tools to my tool-bag and figured it was time to share some of the updates with you. My first post will be about Fluke LinkSprinter 200.  Before I get started, I just want to give a shout-out to a fellow Tech Field Day delegate,  Bob McCouch over at HerdingPackets.Net , for telling me about this tool. So what is so special about the  LinkSprinter 200 and why do you need one? Simple, just ask yourself if have you ever had to…
  • Track down what switch and port a network element (Computer, Server, WAP, etc) is connected to?
  • Find out what VLAN a port is in?
  • Does the port support PoE?
  • Check to make sure DHCP is working?
  • Find out what speed and duplex a port can operating at?
  • Do you have connectivity to your gateway and the internet?

The  LinkSprinter 200 tool can do all of that and fast! I used it for a network migration the other day and it saved us hours of work.  Normally we have to trace cables to find where printers are plugged into so we can change VLANs and port configurations.  Normally this takes about 10–20 minutes per printer,  with the LinkSPrinter we were able to get all the printers done in about 10 minutes.

Cisco Live 2015 – Guest Keynote Speaker

images The time has come to announce the guest closing Keynote speaker for Thursday!  This information is hot off the press so be prepared for some serious excitement! The closing Keynote speaker is going to be just AWESOME.  I have been asking, as well as have others, for a few years to get this man for the closing keynote.  He is a person whom I have a lot  of respect for.  I respect him because he has embraced the cause to teach us about hard work. determination, and perseverance..  I will also admit that he is a man who I have a “man crush” on.  Without further delay and embellishment, it is none other than the former late night host of QVC,_ **Mike Rowe**_! (Yeah OK – he has done a few other great shows like Somebody’s Gotta Do It  and voice overs since his time at QVC). [mike_rowe_dirty_jobs][1]  

Cutting The Cord – Ditching the CableTV Bundle!

Tombstone (1) I finally did it! I cut the cord on cable today (2/7/15). I have been considering cutting the cord for about a year or so now, but never was really motivated to cut it.  My cable bill was high (over $200/mo), but I was in a bundled package with my cable, internet, and phone –  so the amount of work to get out of that just seemed to much.  That was until I received my January 2015 cable bill –  that bill was almost $300/mo!  Not sure what happened, but from what I can understand all the cable companies (not just mine) prices jumped in January 2015.  Finally the pain of paying that bill every month was too great for me to bear anymore and I started the work for cutting the cord. The first thing I actually did was start to look at ordering TV from a satellite provider as that rate would be less than I was paying now.  I was so close to ordering oh so many times, eventually realized that I would be getting myself back into a long-term contract again.  I said to myself and my wife that it was time to just bite the bullet and figure this out.

Cisco Live 2015 – Announcements – I Don't Want to Miss a Thing

In case the above video has not given it away, the CAE band on Wednesday June 10th @ 7:30 at Petco Park for Cisco Live 2015 is none other than Aerosmith!  We have had some great bands over the years (KISS, Lenny Kravitz, Imagine Dragons, OK GO, just to name a few) and I suspect that this year will be one of those memorable band years.
This also has me wondering if our hat will be one of these that Steve Tyler has worn in the past:

JNCIE Ent Workbook

TITLE

 
Over the past few months I have been preparing to take the JNCIE-ENT lab exam.  As part of my studies I adopted the plan of “Teaching What I Am Studying.”
The culmination of all the study, over 500 pages of text,  will be for sale  via Leanpub shortly. The reason I have chosen Leanpub is because I will be able to publish updates and people who have purchased the workbook will be able to get those updates free.  With my past workbooks, once they have been published – they are final.  Using Leanpub, I will be able to keep them updated with new technology and information when necessary.
Below is a link where you can sign-up to be notified when the workbook is published.
 

Meet the new ISR Series – ISR 4000 running IOS-XE

ISR4400Series In June of 2013 Cisco released the newest member of the ISR family, the ISR4451-X router (Cisco –  blog post).  At that time it was the only model in the ISR44xx line, but today it now has some new siblings.  Today, October 2, 2014, Cisco has introduced some companious, namely the ISR 4321, 4331, 4351, and 4431.   The below graphic from Cisco that shows the new line and the performance characteristcs of each.  You will note, for example, that the ISR4321 says 50–100 Mbps.  The base version of the device will support 50 Mbps, but to move to 100 Mbps on that box you just need a software license.  This will allow a network to grow with it needs without having to replace hardware, you will just have to add a license file.  Back in the ISR G1/G2 days we need to sometime replace hardwre in order to gain additional performance, but that is not the case with the ISR 4000 series.  Much of that comes thanks to Cisco using IOS-XE on these devices.  A quick blurb IOS-XE from the previous link is :
