We have been running ArubaOS-CX for about a year. An issue that continuously comes up are interfaces that have a physical status of "blocked". This has been caused by and interface that is in a up up state but no mac address on the interface. Port access is seeing this as an issue and puts the interface in a blocked state. The only way to resolve this issue is to either bounce the port or reboot the end device. I have seen these on interfaces that connect to different scada style devices. Below is an example of what we are see. Any help with this would be greatly appreciated.
