3570G Stack issues

Hi 

 

   I`m fairly new to all of this and I need a bit of help with a problem that I ran into recently..

I have 2 3750G Cisco switches in a Stack that I`m using as Layer 2 switches for distribution purposes. The problem that I`m having is that anything that I`m plugging into switch 2 (which is the stack member) seems to be having issues as far as connectivity is concerned. I have 2 3560s that are up linked to the stack member and both of those cant be discovered by Cisco Network Assistant. Also my AP are dissociating and associating and when I plug into the Stack master these problems go away, so I`m assuming it has something to do with the stack configuration..

 

Any help would be appreciated 

Thanks

Do the following: 

1.  Command:  test cable tdr int <PORT>;

2.  Wait for about 5 to 7 seconds for the process to run it's course; 

3.  Command:  sh cable tdr int <PORT>; 

4.  Post the complete output to #3.

I guess I should have mention that both of these switches are Fiber switches and the TDR command only works for ethernet ports

Well, I didn't know they were fibre optic.
So let's try something else. Post the complete output to the command "sh interface <PORT> controll".

Here int the output for the show interface G 2/0/1. Thats on the stack member on a port that one of the 3560s is connected to..

Can I see the output to the command "sh interface <PORT> controll" from the 3560 side?

Below is the output from the 3560 interface

What are the uptimes of the two switches?
Highlighted

The up time on the 3750 stack is 12 days. 

while the Uptime on the other one is just a couple of days
