FastEthernet0/2/0 is administratively down, line protocol is down 7413439 packets output, 4142244523 bytes, 0 underruns 210455 output errors, 247846 collisions, 1 interface resets
Look at that error:
Check:
1. Physical Cable
2. Speed
3. Duplex

What is connected to G0/2? You've got a bad cable.

WTF.
I have TWO questions for you:
1. Where did you source your cables from, some hack from e-Bay?
2. Do you actually have a network engineer? A credible network engineer?
The line errors that we've highlighted, that is Networking 101. If no one from your organization saw it then you've got trouble.
