Hi All,

I read OpenFlow1.0 Spec and I have some doubts in my mind regarding Stat
Reply Message.
The Spec clearly defines the reply body for all types of stats request
messages like Flow Stat,
Queue Stat etc.

Now, suppose OpenFlow controller sends a Queue Stat request for Queue ID=1,
which actually doesn't exists in switch. Then what will happen? Should the
switch send an error in response?
If so, then what error type & code should be returned?

Again, is it valid to have a stat reply message without body, that mean
stat reply message contains only the OpenFlow header?

If any of you have any info regarding these, please let know.

Thanks & Regards,
Mrinmoy
