I'm trying to figure out if some Diagnostic failures are real or not. These are 3750x switches, running 12.2(58)SE2.
Story is.... A stack port kept flapping up and down. Replaced the cable, didn't fix the problem.
So I started to look at closer, and run some diagnostics on the switch.
After I've run some diagnostics (diagnostics start switch XX test all) and I get the "TestPortAsicCam --- Failed" result back. So I run it on the other switch in the stack, and I get the same thing. I then went and ran the diagnostic on two separate switches and both came back failed as well. If I re-run the diagnostic on the original two switches sometimes the result comes back failed, and other times it comes back okay. At this point I’m thinking it is a software issue and the hardware is completely fine. I can’t believe that four switches would have the same hardware failure.
So what does everyone else think? An actual issue or not? I've seen on the Nexus 7000 switches where diagnostics would fail. We ended up RMA-ing several line cards; eventually Cisco came out and said it was actually a software issue giving false positives. I'm sort of thinking I'm seeing a similar issue here as well.
Also, there is no TAC support on these switches so I can't just open a case.

This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
