MAC Flooding Apple USB-C Hub

[ciscoprolin]

Dear All,

our Catalyst 2960X was MAC flooded by an Apple USB-C Hub with randomized MAC addresses. Have you ever observed a similar behavior in connection with Apple USB-C Hubs ?

Port-Security brought the MAC flooding to a halt. Within a few seconds the USB-C Hub (built into a Philipps Monitor) filled the Switches CAM table in a matter of a few seconds. And NO there are no Virtual Machines running on the end device behind the USB-C hub.

Any ideas what this could be would welcome.

Thanks,

Thorsten

Hello,

I have looked around and the only thing I could find is that maybe the driver that is on the CD is outdated...

Check page 6 of the attached user guide and see if you can find a newer driver...
