Cables Fail - Part 22025-06-15
Recently my friend swapped out one of their 1Gb switches with a 10Gb switch, but it refused to link up with their other 10Gb switch. After some troubleshooting today, it turned out to be the cable linking them. Despite being CAT 6A, it could only successfully negotiate at 1Gb. I wouldn't be surprised if there were carrier errors at 1Gb too, but I didn't bother checking logs.
