The IESG has received a request from the Operations and Management Area Working Group WG (opsawg) to consider the following document: - 'IEEE 802.11 MAC Profile for CAPWAP' <draft-ietf-opsawg-capwap-hybridmac-06.txt> as Proposed Standard The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the ietf@ietf.org mailing lists by 2014-11-10. Exceptionally, comments may be sent to iesg@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract The CAPWAP protocol defines two entities: a Wireless Transmission Point (WTP) and an Access Controller (AC). The CAPWAP protocol binding for IEEE 802.11 defines two MAC (Medium Access Control) modes for IEEE 802.11 WTP: Split and Local MAC, and describes the required functionality split between the WTP and AC for each mode. However, in the split MAC mode, the partitioning of encryption/decryption functions are not been clearly clearly defined. In the Split MAC mode description, IEEE 802.11 encryption is specified as located in either at the AC or the WTP, with no clear way for the AC to inform the WTP of where the encryption functionality should be located. This lack of specification leads to interoperability issues, especially when the AC and WTP come from different vendors. To prevent interoperability issues, this specification defines an IEEE 802.11 MAC profile message element in which each profile specifies an unambiguous division of encryption functionality between the WTP and AC. The IEEE 802.11 MAC profile is used as follows: the WTP informs the AC of the supported profiles during the discovery or join process and the AC configures the WTP with one of the supported profiles when configuring the WLAN.
