Here in my company there are Cisco small business SF300 series, small business switches and Cisco 2960 Enterprise switches. The problem is after some time their fastEthernet port has stopped working. How can i resolve this issue? I have tried to reset the small business one but i couldn't get any change. please can i get some one from Cisco help to resolve this issue?
What is the status of the interfaces ? Are they up and connected ?
Once you hit the problem how do you recover ? Do you do a shut/no-shut ?
What to logs in the switches suggest ? Lookout for ports going to err-disabled state or something ?
