A Note on Intellectual Property

• IETF IPR policy requires that participants who
  are aware of IPR on IETF submissions declare it
• Both first party and third party declarations
• See RFC 3979
• IPR declarations were received from several
  companies on pre-cursors to CAPWAP
• At least four companies on four different specs
• One company had different terms for different
  specs
• Not clear how/if that IPR relates to current
  CAPWAP specifications, especially post-split
• Chairs will be working with AD and Secretariat to
  clarify and update IPR declarations
• Hopefully to include details about what portions
  of the spec(s) are encumbered
• Please update existing declarations!!

MIB Status

• Does it make sense to produce two MIBs to match
  the two CAPWAP protocol specs?
• CAPWAP Base Protocol MIB 802.11 Binding MIB
• Volunteers needed
• Are there proprietary MIBs available that we
  could use as examples to accelerate this work?
• Must be publicly contributed to the IETF
• No promises about using them directly
