Hi Everybody,

 

I noticed that the switch sends feature request messages to the controller
(as if they were echo requests). 

This does not cause any problem (the controller simply ignores them) but 

is there any reason behind this? Are these messages serve the purpose of
health messages?

 

The following is wireshark capture with OF filter

Thanks,
