Cisco IE2000U Switches doesn't send PRP supervision frames

[chrnor1920]

Hello everyone.

I'm configuring 4 Cisco IE2000U switches (IOS version 15.2-5.E2) to operates the PRP protocol together. The packet duplication and duplicate handling works great. 

My problem is that the switches do not send PRP supervision frames, I don't see any supervision frames when I scan my network (with wireshark).

On the four switches, if I try the command 

show prp statistics egressPacketsStatistics

The value of egress supervision frame is at 0.

My question is why the switches don't send supervision frames ??? 

I hope that someone can help me find the problem.

I don't know much about these switches, but I have helped a couple of people previously by suggesting they upgrade to a gold star release of code - just to get rid of all the known serious issues.

The last two times it resolved the issue.

So ...

Actually I upgraged to the latest version hoping this would resolve the problem, I had a gold star version before.

Thanks for your help I'm still digging.
