So I started off my IT career as an intern for a rather large company in London. I was doing a lot of misc stuff, mostly desktop but always pushed for as many networking bits I could, networking is great. A year later and here I am as a junior network engineer on the path to my CCNA (almost there!)
This post is about VLANs. VLANs in the Cisco world explained how I wish someone had explained to me. Please bear in mind that this will not be a very technical explanation, you can find that elsewhere; this will be helping you get to grips with VLANs, how they work and setting them up. Once you have a better understanding of VLANs you can go and read up some more on Ciscos website perhaps?
