Have an issue on some X670G2-48x-4q switches with Tyco Electronics SFP+ copper cables. On two switches now the port goes down with a "local fault" then comes back up within seconds. Then goes down again at various intervals from a few minutes to 30-40 minutes. Link light never goes out and there are no tx/rx errors.
One switch I was able to get the errors to stop by using a Siemon brand cable. The Tyco cables which were causing issues are now working just fine in other same model/firmware switches. We have 10 other switches using the Tyco cables with no issues.
Anyone ever seen this before? I do have a GTAC case in but figured I would see what the community has seen also.
