The Control and Provisioning of Wireless Access Points (CAPWAP)
protocol binding for IEEE 802.11 defines two Medium Access Control
(MAC) modes for IEEE 802.11 Wireless Transmission Points (WTPs):
Split and Local MAC. In the Split MAC mode, the partitioning of
encryption/decryption functions is not clearly defined. In the Split
MAC mode description, IEEE 802.11 encryption is specified as located
in either the Access Controller (AC) or the WTP, with no clear way
for the AC to inform the WTP of where the encryption functionality
should be located. This 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.

This is now a Proposed Standard.
