Hi Miroslav,

Please elucidate me on the following.

1.      Which field in the delay response indicates the value to the slave 
announed by the master? Is it logMessageInterval?
2.      DelayReq packet is sent by the slave. Thus, the number of DelayReq 
packets to be sent is to be controlled by the slave. Am I right? Why should it 
be an option with master?

An answer to my own question: It is the master being burdened to respond to 
possibly many number of slaves. Hence, it controls the number. Is this the 
rationale for what you have mentioned below?

Thanking you in anticipation,
Regards,
Chandra

That option needs to be set on master. On slaves it sets only the initial 
value, after receiving first delay response message they will switch to the 
value announced by the master.
