Below is the output of show log messages on one of my switch stacks. As you can see I have ports flapping quite often.
Does this just mean the device (computer) that is attached to this port is being turned off or on? If not, then how do I troubleshoot flapping ports?
I thought it might be a spanning tree issue but spanning tree has not change in a long time as shown by "show spanning-tree bridge"
