3. March 2006 CAPWAP Protocol Specification-00 1.Protocol name change to "CAPWAP", per list discussion 2.Addition of the three editors, per AD, Chair decisions 3.Addition of a "Contributing Author“ section, with the known contributing authors to date. IETF guidelines allow additional info to be provided 4.Inclusion of DTLS as the CAPWAP protocol security mechanism, replacing the proprietary LWAPP mechanism. Inserted and modified text reflects Eric and Scott's latest dtls spec, and the list comment discussion to address Sue and Nancy's questions to date. Note that the DTLS entry in the issues tracker remains open. Inclusion of the text at this point is intended to facilitate resolution of any remaining issues. Major changes to sections 2,6,10,15, and smaller changes throughout. Work underway to identify changes needed to complete the DTLS specification 5.Wording changes to clarify that the message types are messages--changes sections 5,6,7,8. Also re-numbered the message type values to remove gaps.

4. March 2006 CAPWAP Protocol Specification-00 6.Addition of a section for WaitJoin Timer, which was not defined. Need to determine a default value. 7.Wording changes in the intro and abstract partly due to DTLS changes, partly changing from passive to active voice, clarity. 8.Removed "gold, platinum, bronze" and the like QOS descriptions, retaining the technical terms only The "metal" terms were used inconsistently in two places - one had uranium but the other didn't, and one included the technical terms and the other didn't. 9.Inserted "IEEE" prior to "802.11" in reference - various sections

5. March 2006 CAPWAP Protocol Specification-00 Other major changes 10.Expand Information Element type field to 16 bits – Issue 1 11.Allow for 802.3 tunneling in Local MAC mode – Issue 3 12.Define a mandatory mode and tunnel type - Issue 4 13.Remove layer 2 mode – Issue 6 14.Specify CAPWAP Fragmentation – Issue 36 15.Define optional tunneling in Local MAC section - Issue 52 An additional 35 issues also resolved – see Tracker

6. March 2006 CAPWAP Protocol Specification-01 1.DTLS related edits –Issue 2 2.AC Address (39), PMK Sharing (42), Combining Messages (45), Model & Serial number (46,71), Max # BSSs (50), Config names (58) 3.Replace “CKIP” with a generic vendor proprietary extension 4.Add Waitjoin Timer Default Value 5.Author, Acknowledgement section updates 6.Possibly re-structure message element definition organization – simplify cross references. Opinions? Create a separate section for all of the message elements, e.g. new 4.3.3, rather than having each element defined in the first place it appears, with subsequent cross references, e.g. 5.3.1 – 5.3.5 Create a table in each of the message definition sections which lists the message elements and if they are optional or mandatory
