Recently I've encountered an issue with our Cisco 3560 Catalyst switch.
The LED of the interface Giga 0/25 was turning into orange after few seconds. After reboot the switch,It was working fine.
To prevent this happen in future again, I want to know the cause of the issue and find the resolution
For the this I need experts support
Any help will be highly appreciated.

Hi,
Can you post the config for interface Gi0/25?
can you issue "sh log" and see if there is an error message?
also, do you have bpduguard enabled on this port?
