Capwap Mailing List: CAPWAP IESG Issue T5

[Pat Calhoun (pacalhou) (pcalhoun]

Here is the IESG Issue:

   T5 - Section 4.3, pag 47 - As I understand the 5 bit field encodes 32
possible 
   wireless bindings (i.e. it's not a bit mask). If true it would be
good to make this 
   explicit. My question is whether there is any reason to start with
value 1 and not 
   with value 0? Assuming this is already deployed, will 0 be a value to
use, or does 
   it have any special significance?

No, this is not a bitmask. I'm not actually sure how to explicitely
state it isn't a bitmask, because in my mind any field is not a bitmask
unless it is explicitely stated, so I will use the term numerical.
Further, there is no reason why zero cannot be used, so I'll renumber
the fields to start at zero.

So I am proposing the following text:

<text>
   WBID:  A 5 bit numerical field which is the wireless binding
      identifier.  The numerical identifier will indicate the type
      of wireless packet associated with the radio.  The following
      numerical values are defined:

      0 -  IEEE 802.11
      1 -  IEEE 802.16
      2 -  EPCGlobal
