Cisco IOS release naming

Calin — Mon, 11 Jul 2011 13:42:26 +0000

Most probably you already know this, but for those who are interested, here is a list of the letter definitions for Cisco IOS release trains. In more human terms, if you have loaded an IOS image like c2900-universalk9-mz.SPA.150-1.M5.bin, what those letters (in this case SPA) mean:

A = Aggregation/Access Server/Dial technology B = Broadband C = Core routers (11.1CA, 11.1CT, 11.1CC) D = xDSL technology E = Enterprise feature set F = Feature Specific enhancements (11.2F) G = Gigabit Switch Routers (GSR) H = SDH/SONET [...]

Cisco CCDA: 640-863 and 640-864

Calin — Wed, 27 Apr 2011 14:11:18 +0000

As you probably know the CCDA exam 640-863 will be replaced by the newer version 640-864. The problem is not that Cisco is changing them (this is actually a good thing) but the fact that are too less materials regarding new exam and a lot of contradictory information.

First of all the official Cisco guide: CCDA 640-864 Official Cert Guide, 4th Edition is not yet available. Ciscopress.com announce it to be available June 10, 2011. [...]

Cisco Network Magic – funny marketing video

Calin — Wed, 07 Jul 2010 10:22:40 +0000

Not too much to say about. We all know that Cisco is investing a lot into it’s image on the market and sometimes we are dissapointed that what marketing is showing is different from the final product, but the next video worth every penny. At least is funny and can bring a smile on your network engineer face.

Enjoy!

Cisco Cius

It seems to me that Cisco want to compete with Apple on the touch screen devices market. The Cisco Cius product confirm this.

OK, skipping the funny part of this story, honestly I believe that Cisco is making efforts to take the (still) open part of the tablet devices market that is not so developed in this moment, and by this I mean the touch screen devices for professional use.

While companies like Apple focus their efforts to develop home use friendly devices, Cisco want [...]

New benefits for Cisco 360 Learning Program

Calin — Tue, 22 Jun 2010 10:19:03 +0000

Today I’ve received an e-mail with the following content:

Cisco: Multiple Vulnerabilities in Cisco PGW Softswitch

Calin — Mon, 17 May 2010 09:36:58 +0000

Cisco EnergyWise is a key part of the Borderless Network concept. According to this document:
