The AC is supposed to react to WiFi Authorization requests with Add Station messages. Such an Add Station will fail with the station is already present in the data path. A Authorization request for a station that the WTP already in authorized state means that the station lost its assoziation without the WTP detecting that. So, clearing it from the data path seems to be appropriate.
README
RFC-5415 and RFC-5416 compliant CAPWAP WTP (and AC) implementation.
This fork is currently focusing on the WTP side only.
STATUS
NOTE: The WTP has been ported to libev, the AC has not been adjusted and is therefor broken for the moment.
WTP tested and working features:
- 802.11b
- 802.11g
- WMM/WME (mostly)
- Local MAC
- single radio, single WLAN mode
- 802.11n (draft-ietf-opsawg-capwap-extension-06)
Only cards with cfg80211 netlink API are supported and only ath9k cards (in particular Qualcomm Atheros AR5418) have been tested.
Planned WTP features:
- encryption (WPA2)
- Hybrid-MAC (RFC-7494)
INSTALLATION
Requirements
NOTE: To run WTP you must have a wireless card that has Linux driver based on the Generic IEEE 802.11 Networking Stack (mac80211).
