First off let's start out by saying that Isolated VLANs and Private VLANs are two completely different things... they are not at all the same. To a network administrator, this should make perfect sense. However, a Server or Virtualization Administrator may or may not know the different. Because of this, I hear many non-network Administrators toss around the term "Private VLAN", when they actually mean to say "Isolated Vlan", or more specifically what they are referring to is a "Non-Routable" VLAN.

Visio Network Stencils for Cisco Routers and Switches
Looking for Cisco Visio Stencils -- Access the entire Cisco Visio template library via the links below. I have tossed in a couple of extra links that should pretty much meet any of your Visio needs.
How to Reset Cisco Catalyst 3750 Back to Factory Defaults
Need to reset your Cisco Catalyst 3750 back to the factory default settings? Have you forgotten your password? Well you have come to the right place. Note that I am assuming that you have already established a console connection to the switch using a Cisco serial cable (rollover cable).
Cisco: Principles of Application Centric Infrastructure
Attending Cisco Live 2014 in San Francisco this week?
Well, get ready to hear a lot about ACI (Application Centric Infrastructure). It's almost here and its everywhere. And the acronyms, holy crap, get ready to get hit upside the head with of ton of those that you have never heard before. Cisco is only a close second to VMware when it comes to their love of acronyms.
Subnetting for Complete Idiots: Part I
Little-professor-1Let me first start off by saying that I do not actually think that I am a complete idiot, however it being educated by the Georgia Public School system I can safely say that there are a few subjects where my knowledge is lacking. Specifically mathematics. Honestly everything else that you might have missed learning in high school you can pretty much pick up along the way just by picking up a book or through a bit of on the job training. But not math -- its just one of those things that you are never going to find yourself learning for fun.
HomeLab: Simple DHCP Service Configuration on a Cisco Router
Sometimes when I learn something new in the world of technology, I am often amazed that something that I assumed was technically advanced is rather quite simple.
Such is the case with configuring DHCP on a Cisco Router. I mean, is it just me or do network guys sometimes act as if everything that they do is takes elite technical skills and tons of experience. Don't get me wrong, I know that networking is not exactly easy. But can we just agree to admit that once in a while some things are easier done than said. Anyway, for me this was the case with configuring a DHCP pool on a Cisco Router.
HomeLab: Configure a Range of Ports on a Cisco Switch
rFirst off let me say that its really good practice to configure ports one by one, at least when you are starting out in the network world, as the repetition of typing the same thing over and over helps you to remember the proper commands. Hell this is one of the reasons that I blog the stuff that I do... I'm trying to make sure that I do not forget what I just learned.
