Troubleshooting Question

Hello 

what to do here

Please can you help me regarding this 

Massive degradation in local network throughput

I just tested to copy a 4GB file from the network share to my local hard disk and it just gave me 1MByte/s where I would expect 100MByte/s.
It looks as if only the users in the 1st floor are affected. They are all attached to the switches sw1 ... -sw3. I just checked the link states on the switches and they are all ok except the fiber uplink on -sw1. This link intermittently switches between green and orange.

what i check here...

stack cable has nothing to do with how asics speak to each other internally

there are multiple ascis per switch and ports are assigned to each asic block

how they communicate together you need to ask Cisco that directly through TAC maybe they can answer it I cant I don't know what programming they use in their asics and I have no real requirement to know as you cant even access it

If you want to see what ports are assigned to each asic use

show platform pm platform-block

it tells you an STP- change came from that port GigabitEthernet1/0/32 5 minutes ago ,if you follow the port through cdp whats connected on it,  run the command again on next switch and so on until you find the source of the STP change
