ccna_certifiedIf you get the networking joke in the title, laugh a little.  I thought I was clever.

But I got my CCNA a while ago.  Loved it.  ICND-1 was a cinch but INCD-2 had me worried though the exam but I passed both with flying colors.  WAN technologies had me worried and I still have a little trouble with MPLS but I think it is similar to Frame-Relay but Frame-Relay is static whereas MPLS is more dynamic.  If anyone reads this let me know if you have questions about CCNA.  I’d love to talk about it.  Unfortunately I don’t get a lot of poeple to talk about it with.  The CCNA track was a ton of fun with the home labs and Jeremy from CBTNuggets was awesome.  Odom’s bookwas great too.

But now I am on to bigger things.  I debated a lot wether to follow another CCNA track like Security, Wireless, or Voice but I kept reading about folks who got to those after you got to CCNP.  I can understand that.  Where I live I doubt I’ll need much past CCNP but the dream of day being CCIE is something I’ll just toy with for now.  The job market around here isn’t great for IT.  A lot people think I should move but my wife and I are very involved in the church we goto and really like staying there.

To study the CCNP track I’m going with the Route Exam fist.  Using Jeremy from CBTNuggets and Diane Teare’s Cisco Press book at the moment.  I like the idea of going with the CCNP Routing and Switching Track so far.  It’s a ton of fun and make soooooo much more sense to me than the MCITP track I followed with Microsoft.

Not to knock against Microsoft but a lot of how to the application works in the background (Like DFS Replication) is unknown!  I know how to set it up, but I’d really like to know how it knows when files match!  Does it use checksums?  I hate that grey area of understanding IT.  With Cisco and networking I can totally understand the logic of everything I work with.  How does dot1q work?  Well the switch adds the vlan tag in the layer 2 header of an IP packet so that the switch at the other end of trunk link know what VLAN it is for!  It’s a 4 byte tag!  I know that information down to that level!

Anyway.  Really excited for CCNP.  I’ll likely post things about what I learn on here.  A lot of the material is likely gonna be new so I’m quite excited to jump in.

For those who didn’t get the joke.  In a Cisco, there is to states for an Ethernet (Or Serial) Interface; Link Status and Protocol Status.  If you have Up and Up that means the cable is connected and the Line Protocol is up and everything should be working.  So CCNA Up and Up means I have started and understand the content.  An Up and Down in networking is where the cable is plugged in but the Line Protocol is Down.  This means I have started the process but don’t completely understand the content.
