As my CRS317 had port flapping problems with my CRS328 I had to RMA it. It is now in repair and it will take 6 to 8 weeks before I get it back. In the meanwhile I had to squeeze all my 10Gb computers into the SFP ports on the CRS328.
I now have a problem with my workstation that is connected by UTP to the CRS328 by a S+RJ10. If I turn on the PC there is no connection. If I unplug the S+RJ10 and replug it everything works fine. In the CRS317 the S+RJ10 worked flawlessly
What could be the cause?
