There I was, thought I'd have a go at implementing a VLAN on the Core switch yesterday. Just to prove the concept and make sure I've got it clear in my head what to do. I telnet into the Switch and start tweaking some settings, next thing I know connectivity to the Internet Stops.. What have I done? I look at the steps I took, and all seems well. I then revert all the settings back to their initial settings and still no Internet.

Quick phone call to SWGfL and it would appear an outage has just happened! Why did this have to happen when I'm tweaking something major. Two hours later we were back on line.

VLAN didn't work right anyway, obviously missing something so I need to look at things again but I've just lost all the will to live at the moment!
