Ten years ago I’ve passed my first Cisco exam: CCNA! What was supposed to be just a marginal skill for a junior systems engineer became both my job and my passion.
Ten years and 21 Cisco exams later (and a bunch of other vendors), with 2 labs in Brussels, 1 FAIL and 1 PASS, I’m still excited about networking and I hope the next ten year will be as valuable and inspired.
Last week I had the opportunity to attend Cisco Live in Milan. This is my second time at Cisco Live, I’ve been in London last year .
Some people still doesn’t know what Cisco Live is. Is it an event for pre-sales? A technical training? A party with free beer for nerds? I can say it is it all and much more.
At Cisco Live you have the opportunity to participate in very deep technical sessions, some with hands-on labs, and to talk with the smartest guys in Cisco.
Questo post e' dedicato ai networkers iscritti al CUG di AreaNetworking.it per condividere la mia esperienza del Cisco Live! 2013 a Londra.
Ho visto diversi messaggi in ML e dato che la risposta sarebbe un po' lunga e magari puo' interessare a piu' persone ho deciso di scrivere direttamente un post qui. Ho avuto il piacere di partecipare al Live! 2013 a Londra e salvo imprevisti a Gennaio parteciperò anche a quello di Milano.
Today I’ve passed 642-874 ARCH exam that in conjunction with CCIE and CCNP entitles to obtain the CCDP certification.
To prepare the exam I’ve used the official study guide along with the documents in the Cisco Design Zone .
The hardest part of the exam preparation was to study technologies I’ve never really implemented and to focus on design, scalability and restrictions more than on the commands.
Quite often I have to debug a wireless client roaming across lighweight Cisco APs to confirm it moves between APs as expected in the network design.
On the WLC the command is “debug client MAC”. The command shows all the events related to the specific client including:
Reassociation received from mobile on AP 00:23:ab:ba:YY:XX that means client moved to the AP with radio MAC 00:23:ab:ba:YY:XX. Since I’ve named all the APs and and I’ve a map with all the positions, I’d like to see the names in the debug instead of MAC.
Got mail from Cisco:
In really enjoyed to read all the blog post of people passing the CCIE lab exam over the years. I’ve found the stories very inspirational so now it’s time for me to give back.
I started working as a system engineer in 2001 supporting Microsoft Windows 2000 client and server for a bank. I had the opportunity to work with some network engineers for a project and being intrigued by the new world I started to study what seemed to be the right choice for the moment: Cisco CCNA.
I noticed that not everybody knows how to download Cisco certs PDF files or order additional printed copies. Just open this link , login with your Cisco credentials and enter the menu “Certification Fulfillment”.
An additional CCIE plaque costs 150USD, paper certs cost 15USD.

I’ve passed the CCIE RS lab exam yesterday in Brussels, results arrived this morning:
Cisco stopped to publish CCIE statistics some time ago but in Cisco Live presentations we can find some slides like this:
A couple of days ago on twitter Bob McCouch who passed his lab on February 21st posted this:
I know 14 days are not enough to make statistics, but let’s play with the numbers since they’re very fresh.
There’re 9 CCIE lab locations worldwide , suppose each lab locations ha 5 seats per day.

Cisco Live! Europe : I’m in!
First time here, the impression is like being in the Willy Wonka chocolate factory with the big difference you can touch everything without disappear.
As my job is not focused on a single technology I’m registered to many different sessions, from WiFi to Security, from FCoE to Routing/Switching.
A longer review will follow. It’ll be a long week.
