Hello, I have a bunch of Brocade switches ICX 7450 (firmware 08.0.3k). The problem is that I have a lot of logs from flapping ports. The ports commes up and down continuosly, but I don't have from user perspective, any issue. Is that a logging problem? How does it verify if a port is up or down? How can I know if the port had comme down trully?
When I check the switch, the port is up. But I still have the logs 😞
You can definitely see a lot of layer1 flaps on some of those example ports. Are these all running through the same patch paneling? Any possible interference? Any easy test would be to hook up a laptop/pc on a port seeing flaps (ex 3/1/36) with a short, direct cat5 cable and see if the port still flaps. That would tell you if the issue is in your cable plant. It definitely looks like a physical issue to me.

I only show one of them but I have the same problem in almost every switch. They're at different places, so différents connections and patch panneling. Anyway, the test you're proposing is good. I'll do it.
