We have two Cisco 3560G switches and are running cat-5 between them using the gbic ports (using the plug in adapters). At night the gbic's have been going down, acting like nothing is plugged into them. If i unplug the cables and plug them back in it comes up. It has never gone down during the day with high activity.
Any info or expertise on this would be greatly appreciated. There are no error or warning logs on the cisco's.
