Passing the CCIE Collaboration Lab was really hard and a very nice and entertaining experience, which I feel very happy to say that I completed the challenge!!
I will be very short on this post and will make it technical and a bit emotional for the people out there that may benefit from it at all
How many times is enough? Well I started this year thinking that it was going to take as many times as it needed to take… Financially this could be brutal and indeed it is. But the reality is that you need to make everything possible to make it happen. Just make sure you will get it, no matter what! and put every effort possible to achieve the goal.
While my experience on my first attempt was not the brightest one because I failed, I was able to open my mind and think on endless possibilities and maybe potential recommendations. I hope this helps other with their studies and strategies.
Studying and Muscle Memory: Do you studying… I think many instructors across the globe could not stress this one enough… but its right, going into the Lab with just few practice is not enough, muscle memory plays and interesting role on your experience. The need to know your IOS commands without Context Sensitive help is key (this one got me very bad).
I promise this will be a very short one. This week I purchased 3 9971 with the camera in order to get ready for my rack rentals for CCIE Collaboration, well when I got them I noticed that the phones belonged to someone else(Duhhh!!).
I needed to do a factory reset on those guys, or at least be able to remove the ITL files.
My problem was that I could not do any of these because the Admin Settings was locked by a password. Of course you can remove this password but if only if your phone is able to get the SEP config from your CME (off course if you are using CME) - TCLSH procedure here http://collabengineer.com/2014/11/15/cisco-sip-phones-admin-password-removal-cme-tclsh-operation/
On this one I wanted to share a really nice way to remove the Admin password from Cisco SIP phones.
It really is annoying to type the Admin password every time you need to modify or at least take a look at the configuration on your phone.
As you may know when you configure a SIP phone on CME you need to give it a username and password, also SIP is kind enough to publish the SEPXXXXX.cnf.xml file to Flash
Just for curiosity, I would like to know how is the people on this group preparing for the CCIE Collaboraiton Lab, right now here is my preparation and roadmap:
I have completed a lab in order to be able to study most of the technologies included in the blueprint, here is what I have:
3 Cisco 2811 64 PVDM2 1 Cisco 2821 128 PVDM2 1 Cisco 3750G 24 Port 1 Poweredge 1950 III 32GB - 2 TB HD - 2 XeonQuadCore E5240 2.4Ghz 5 Cisco 7961 2 Cisco 7965
Hi there, today I have a customer that wanted to upgrade from CUCM 9.1.2 to 10.5 - which sounds pretty easy… think again, so this is a BE6K deployment where CUCM instance was configured with the recommended OVA from CCO. When starting the upgrade I found that the upgrade didn’t wanted to proceed as expected. and I was getting the following error:
Installation of UCSInstall_UCOS_10.5.1.10000-7.sgn.iso failed
An error has occured but no messages are available. This can happen when another administrator is working on the system at the same time and triggers an error.
Hi people, I wanted to take this opportunity and share my toolbox and workflow with you. In case you don’t know who I am and what I do here is a quick reference note.
What I do and who I am:
I’m a Lead Technical consultant specialized in Cisco Unified Communications and Collaboration (a mouthful, but really cool stuff … that, I can assure you!) – yes I do some other stuff but I could not call myself an expert, such as in routing & switching, Network design and architecture. I’m learning a bit more about security, which I though I knew something but not really!
Cisco Live 2014 – San Francisco
Just wanted to take this time to talk about my experience at Cisco Live 2014, representing the Modcomp team.
It was a great experience and a nice way to meet with people that is in the same boat you are, Engineers that are seeing the same issues you see and others that have it all figured out (You want to be like them!!).
So just to get you started off the narration of this adventure, I wanted to start by adding few things that I think deserve to be mentioned:
So in the traditional Campus Design it used to be Layer 2 from the Access Layer to the Distribution and to the Endpoints, running Layer 3 on the Distribution and the Core, and in most of the cases, you will have a Core/Distribution approach called Collapsed Distribution Core. as shown in the example:
Now moving from that model to a new and recommended approach you can take a look at the Layer 3 or Route Access layer Design, this one has many benefits as follows:
Hi there, I have been looking at the new collaboration edge deployments, in order to support Jabber from remote networks without the need of using a VPN (What a relief!!! - I was actually getting slammed from customers because of the lack of options from Cisco). Doing some research I was able to find the following documents:
