Q. What does this entry in the status window for an interface indicate:

ifLastChange.8 >= sysUpTime.0

A. This message means that the time being reported by the device for the last change for the interface at index 8 occurred before the last time the device reported it started, which is logically impossible. For example, if it's 4:00pm now, it says the device has been up for, say, 15 minutes, but that the time of the last change was 3:30pm.
