Hi Francois and co-authors,
I think you are correct. So I have no objection in changing that in the
Errata.
Regards,
Shahram

Subject: Re: [mpls] [Editorial Errata Reported] RFC3270 (1910)
Hello,
Just looked back at RFC3270:
MAPnb defines the number of MAP entries carried inside the DIFFSERV
object.
Each MAP entry defines the mapping between one EXP (now "COS") field
value and one PHB.
Since there is only 8 possible EXP values, I think:
* MAPnb should actually be encoded over 3 bits, and not 4 bits
* value range should be 0-7.
Does that sound right?
If yes, I can update the errata with appropraite required changes.

Dear ALL:
This MAPnb column occupied 4 bits in the object. So it can be set to
any
value from 0 to 15.
Corrected Text will be
--------------
MAPnb : 4 bits
Indicates the number of MAP entries included in the DIFFSERV
Object. This can be set to any value from 0 to 15.
