33 .Nd "set/query 802.11 wireless debugging messages"
37 .Op Fl flag|+flag Ar ...
41 command is a tool for enabling and disabling
42 debugging messages in the
49 will display the current messages
52 When run as the super-user
54 can be used to enable and/or disable debugging messages.
56 To enable debugging messages of a certain
60 to disable such messages use
62 Multiple messages can be enabled and disabled with a single command.
64 Messages are organized in the following groups:
65 .Bl -tag -width ".Ar dumppkts"
67 general debugging facilities; equivalent to setting the debug
71 dump packet contents on transmit and receive.
75 errors encountered during input handling.
77 extended rate set handling (for 802.11g).
79 information element processing in 802.11 management frames.
81 management of per-station state.
83 802.11 station association processing; particularly useful to
84 see when stations join and leave a BSS.
86 802.11 station authentication processing.
88 scanning operation; especially useful for debugging problems
89 with not locating an access point.
91 errors encountered during output handling.
94 state machine operation.
96 802.11 power save operation; in hostap mode this enables
97 copious information about buffered frames for stations operating
100 802.1x operation; not presently meaningful as 802.1x protocol
101 support is implemented in user mode by the
105 802.1x state machine operation; not presently meaningful as 802.1x protocol
106 support is implemented in user mode by the
110 radius backend operation as it relates to 802.1x operation;
111 not presently meaningful as 802.1x protocol
112 support is implemented in user mode by the
116 dump packets exchanged with the radius backend for 802.1x operation;
117 not presently meaningful as 802.1x protocol
118 support is implemented in user mode by the
122 include key contents when dumping packets exchanged with the
123 radius backend for 802.1x operation;
124 not presently meaningful as 802.1x protocol
125 support is implemented in user mode by the
129 trace operation of the WPA protocol;
130 only partly meaningful as WPA protocol
131 support is mostly implemented in user mode by the
137 trace operation of the Access Control List (ACL) support; see
141 trace operation of WME/WMM protocol processing.
143 trace operation of Atheros SuperG protocol processing.
145 trace operation of IEEE 802.11h protocol processing.
147 trace station inactivity processing; in particular,
148 show when stations associated to an access point are dropped due to
151 trace station mode roaming between access points.
154 The following might be used to debug basic station mode operation:
156 .Dl "wlandebug -i ral0 +scan+auth+assoc"
158 it enables debug messages while scanning, authenticating to
159 an access point, and associating to an access point.
163 Different wireless drivers support different debugging messages.
170 module for 802.11 protocol processing typically support
171 most of the debugging messages while devices that
172 implement parts of the 802.11 protocol in firmware do not.
174 Some debugging messages are no longer meaningful
175 because protocol processing has moved from the operating
176 system to user mode programs such as
179 .Xr wpa_supplicant 8 .
