01:40:30.483000 | 7c:7a:91:50:27:4c | 802.11 State | <AID=6>[abgn](pre found) lost from assigned <AP=97> ESSID=corp-mixed-peap Ch=44 BSSID=00:0c:e6:5a:1b:44 reason=Station lost from AP
01:40:30.503000 | 7c:7a:91:50:27:4c | 802.11 State | <AID=6>[abgn](pre lost) quasi found on unassigned <AP=96>(rssi=-256) ESSID=corp-mixed-peap Ch=44 A-BSSID=00:0c:e6:5a:1b:44 reason=Station discovered
01:40:30.503000 | 7c:7a:91:50:27:4c | 802.11 State | <AID=6>[abgn](pre quasi found) quasi found on unassigned <AP=105>(rssi=-256) ESSID=corp-mixed-peap Ch=44 A-BSSID=00:0c:e6:5a:1b:44 reason=Station discovered
01:40:30.503000 | 7c:7a:91:50:27:4c | 802.11 State | <AID=6>[abgn](pre quasi found) found on assigned <AP=97>(rssi=-256) ESSID=corp-mixed-peap Ch=44 A-BSSID=00:0c:e6:5a:1b:44 reason=Station discovered
station-log>
(pre OLDSTATE) NEWSTATE from [un]assigned <AP=id>
Here after "pre" the OLD STATE is printed while other state is the NEW STATE
1 Only ASSIGNED AP must send lost msg, for example:
01:40:30.483000 | 7c:7a:91:50:27:4c | 802.11 State | <AID=6>[abgn](pre found) lost from assigned <AP=97> ESSID=corp-mixed-peap Ch=44 BSSID=00:0c:e6:5a:1b:44 reason=Station lost from AP
2 If some UNASSIGNED AP finds a LOST station, for example:
01:40:30.503000 | 7c:7a:91:50:27:4c | 802.11 State | <AID=6>[abgn](pre lost) quasi found on unassigned <AP=96>(rssi=-256) ESSID=corp-mixed-peap Ch=44 A-BSSID=00:0c:e6:5a:1b:44 reason=Station discovered
than it will be marked QUASI FOUND
3 If some UNASSIGNED AP finds a QUASI FOUND station, then it will continue to be QUASI FOUND, for example:
01:40:30.503000 | 7c:7a:91:50:27:4c | 802.11 State | <AID=6>[abgn](pre quasi found) quasi found on unassigned <AP=105>(rssi=-256) ESSID=corp-mixed-peap Ch=44 A-BSSID=00:0c:e6:5a:1b:44 reason=Station discovered
4 If handoff to this UNASSIGNED AP is done than for QUASI FOUND.
The station only gets marked FOUND, in print this AP will now call "assigned" as assignment is transferred to it by now. So two prints can be expected for hand-offs; the second one marking it found.
01:05:10.414000 | d0:b3:3f:1b:fa:42 | 802.11 State | <AID=2>[bg] handoff <OLD_AP=133> RSSI (-256 -256) <NEW_AP=97> RSSI (-68 -68) ESSID=corp-wpa2psk Ch=1 BSSID=00:0c:e6:5a:86:47 reason=Normal handoff
01:05:10.417000 | d0:b3:3f:1b:fa:42 | 802.11 State | <AID=2>[bg](pre quasi found) marked found as received handoff ack from assigned <AP=97> ESSID=corp-wpa2psk Ch=1 BSSID=00:0c:e6:5a:86:47
5 If some ASSIGNED AP finds its previously LOST or QUASI-FOUND station,
It will immediately mark FOUND.
5.1 If no other UNASSIGNED AP have marked it QUASI FOUND:
01:40:30.503000 | 7c:7a:91:50:27:4c | 802.11 State | <AID=6>[abgn](pre lost) found on assigned <AP=97>(rssi=-256) ESSID=corp-mixed-peap Ch=44 A-BSSID=00:0c:e6:5a:1b:44 reason=Station discovered
5.2 Else station will be marked QUASI FOUND by some other UNASSIGNED AP and print will be:
01:40:30.503000 | 7c:7a:91:50:27:4c | 802.11 State | <AID=6>[abgn](pre quasi found) found on assigned <AP=97>(rssi=-256) ESSID=corp-mixed-peap Ch=44 A-BSSID=00:0c:e6:5a:1b:44 reason=Station discovered
6 If LOST station changes Bssid suddenly
Connect to other unassigned or may be same assigned AP then it will be marked FOUND immediately with reason "Ping Pong", for example:
01:40:30.503000 | 7c:7a:91:50:27:4c | 802.11 State | <AID=6>[abgn](pre quasi found) found on assigned <AP=97>(rssi=-256) ESSID=corp-mixed-peap Ch=44 A-BSSID=00:0c:e6:5a:1b:44 reason=PIng Pong
or
01:40:30.503000 | 7c:7a:91:50:27:4c | 802.11 State | <AID=6>[abgn](pre lost) found on assigned <AP=97>(rssi=-256) ESSID=corp-mixed-peap Ch=44 A-BSSID=00:0c:e6:5a:1b:44 reason=PIng Pong
