Question

Internet connectivity comes and goes on school network

Sep 1, 2016 9:36AM PDT

I recently tried to clean up our rack. Everything was hanging in front and it was difficult to work on anything, much less even see what was there due to the spaghetti mess. None of the cables were labeled. I ended up disconnecting all cables from the switches (5 switches total - Cisco SF200-24). I didn't keep track of the exact port (or the exact switch for that matter) that every cable was connected to. Since I re-ran the cables and reconnected them to the switches we have had trouble with internet connectivity. Apprx only 30% of all the computers on our campus will have internet connection at one time. All computers will at least identify as being connected to our network, but the internet is spotty. Some even say that that have internet access but they don't. PLEASE HELP!!!

This is something a networker learns.

NEVER CLEANUP A WORKING SYSTEM!

NEVER EVER.

Now that you broke it, your training kicks in or you call the company that set this up to fix it.

This is how most new networkers learn this lesson.

I had to clean it up to make room for a new router, but thanks for your great insight.

I've done so much networking it's not funny when I come across a new networker that cleaned up and broke the system.

Some are just lashing out when you are called in and you wait for them to finish venting that they would fix it if you only told them how.

Wait for it....

Anyhow each system tends to be different so if you are lucky the designer left a diagram or notes then you go over the configuration and see what it broke. At worse you start over, create the plant layout and design and re-engineer the works.

There's a harsh lesson here. Mostly about cleanup and why should let working systems keep working.

I'm sure you see where you went wrong and hopefully learn from the experience no matter how painful it is.
