Roundup of my mind.

Posted August 27th, 2010 by bcarroll and filed in General, General Information

Today I thought I’d write a post that just sorta captures my interests for today. So… blank page.

Just kidding. Actually my mind has been all over the place today. First off as some of you may know, I was chosen as a delegate for Gestalt IT’s special Networking Field Day this September 16th and 17th in San Jose, Ca. Well I got my flight confirmation and I am totally looking forward to it. Can’t wait to see what the vendors have going on as well as networking with some of my peers.

I also have a bit going on with some security updates so that has kept me busy. It’s interesting when courses come up for revision because you basically upgrade every pod, redo the topology if needed, install all the new OS’s and build images for the servers. Sounds fun right?

I’m also heading up to San Jose for a quick day trip tomorrow. Any of my readers in San Jose? If so and you’re at Cisco let me know.

Anyhow, hopefully I can be a little more consistent with my posts from now on. I’m nice and settled back in at Ascolta. The big hinderance has been some family issues as well as the loss of my blog. Apparently my host lost EVERYTHING and had no backups. Oh well. Makes me do some spring cleaning I suppose.

Anyhow, im glad to be back and Ill get some technical posts in the next day or two.

Until then..Happy Labbing!

Woes with VoIP

Posted September 2nd, 2010 by bcarroll and filed in Rants

I’m not much of a voice guy. It’s just not what I do. But today I got roped into an issue with calls dropping about 5 seconds of voice and then picking back up again. I have no drops on the interfaces and the service-policy for QOS has no drops either. I cannot personally recreate the issue, but people are complaining about it. I love this kinda troubleshooting. Did I mention that if you ask one person it’s only happening at one site, but another says its at all sites. Still another end user says this has been happening for months while another says its only been going on for two weeks.

I’m going to have to think about this one for a bit. I guess that’s what I’ll spend my evening doing.

Happy Labbing!

Apology to my readers

Posted August 25th, 2010 by bcarroll and filed in General

I want to take a moment to apologize to my readers.  I have been inconsistent in posting as well as have had to redirect the blog to Ascolta Certification Resource temporarily while dealing with some issues.  I have not 100% recovered but I’m working on it and the site should be back soon- and even better than before.

Thanks for your patience.

Sorry for the inconsistent posts as of late. There is no doubt that I am super busy since moving to IPexpert. Recently I have been working on the Volume 1 Video Solutions as well as the Audio Bootcamp for CCIE Security. It’s a ton of fun but consumes almost every free minute. I’m almost done and will be back soon. Until then you can find some other Cisco related posts at http://blog.ipexpert.com

Un-Productive

Posted February 2nd, 2010 by bcarroll and filed in CCIE General, General Information, Rants

For the last few weeks I have been using Windows 7. Now don’t get me wrong, Windows 7 is really pretty (Like a guy is even supposed to use that word). My Issue is that I feel Less productive than when I was using a Mac full time. I think its time to make a change so I can get back to work. My thought is that I want an iMac for my desktop at home. The only catch there is that I do a great deal of development these days with Camtasia. Why can’t the Mac version be as good as the Windows version? I suppose the same is true with Microsoft office, but we all know the answer to that one.

At any rate, my plan over the next few months…iMac, MacBook Pro, iPad.

Maybe I should take up stocks in Apple!

It's a new year. Is it the year you get your CCIE?

Posted January 6th, 2010 by bcarroll and filed in CCIE General, Polls, Question for Readers

Many people that follow this blog are studying for the CCIE. Others are working on lower level certs. I don’t want to take a lot of time in this post since i’m halfway through my first week with IPexpert, but I’m curious…What are you going to do different this year?

By way of comments- yes comments- what is your plan of attack this year and what do you hope to accomplish?

Mine is! I have the opportunity to take a really quick trip to San Jose and meet my new Boss and fellow instructors. I am really looking forward to it! 2010 is going to be a great year!

In other news….I have 1 class left at Ascolta- SNAA, which is advanced ASA training. A week of VPN with certificates lies ahead of me.

Also 2 for 1 vRack time this weekend at ipexpert. If you didnt catch their post on Facebook you can Email sales@proctorlabs.com to take advantage!

Time for me to hop on an R&S rack and lab a bit.

Change in Venue

Posted December 6th, 2009 by bcarroll and filed in CCIE General, News

As many of you have already heard I have accepted a position with Industry renowned IPexpert. I have had many good years working for Ascolta training and I thank them for all that they have supported me in over the years. They are some of the finest people I have ever met.

I will be finishing up my teaching schedule over the next few weeks at Ascolta but will be more active in the Online Study List for Security and R&S, as well as here on the blog.

As I look forward into 2010 I am excited to see the wonderful changes that will come about. I believe that 2010 is really going to rock.

Stay tuned for posts here related to my new task…CCIE R&S and CCIE Voice.

Can you count the days?

CCNA Routing Protocol Comparison Chart Revised

Posted October 28th, 2009 by bcarroll and filed in CCNA Corner

Routing Protocols Comparison for CCNA 

I have always said I was going to make this chart since I draw it on the board for nearly every CCNA class I teach.  Well, here it is.  I may add to it later.

Name

There is obviously more to it than what you see here but for the CCNA this should be pretty good.
