40 command is a tool for enabling and disabling
41 debugging messages in the
46 without any options will display the current messages
47 enabled for the specified network interface
48 (by default, ``ath0').
49 When run as the super-user
51 can be used to enable and/or disable debugging messages.
53 To enable debugging messages of a certain
57 to disable such messages use
59 Multiple messages can be enabled and disabled with a single command.
61 Messages are organized in the following groups:
62 .Bl -tag -width ".Ar dumppkts"
64 general debugging facilities; equivalent to setting the debug
68 dump packet contents on transmit and receive.
72 errors encountered during input handling.
74 extended rate set handling (for 802.11g).
76 information element processing in 802.11 management frames.
78 management of per-station state.
80 802.11 station association processing; particularly useful to
81 see when stations join and leave a BSS.
83 802.11 station authentication processing.
85 scanning operation; especially useful for debugging problems
86 with not locating an access point.
88 errors encountered during output handling.
91 state machine operation.
93 802.11 power save operation; in hostap mode this enables
94 copious information about buffered frames for stations operating
97 802.1x operation; not presently meaningful as 802.1x protocol
98 support is implemented in user mode by the
102 802.1x state machine operation; not presently meaningful as 802.1x protocol
103 support is implemented in user mode by the
107 radius backend operation as it relates to 802.1x operation;
108 not presently meaningful as 802.1x protocol
109 support is implemented in user mode by the
113 dump packets exchanged with the radius backend for 802.1x operation;
114 not presently meaningful as 802.1x protocol
115 support is implemented in user mode by the
119 include key contents when dumping packets exchanged with the
120 radius backend for 802.1x operation;
121 not presently meaningful as 802.1x protocol
122 support is implemented in user mode by the
126 trace operation of the WPA protocol;
127 only partly meaningful as WPA protocol
128 support is mostly implemented in user mode by the
134 trace operation of the Access Control List (ACL) support; see
138 trace operation of WME/WMM protocol processing.
140 trace operation of Atheros SuperG protocol processing.
142 trace operation of IEEE 802.11h protocol processing.
144 trace station inactivity processing; in particular,
145 show when stations associated to an access point are dropped due to
148 trace station mode roaming between access points.
150 trace transmit rate control operation.
153 The following might be used to debug basic station mode operation:
155 .Dl "wlandebug -i ral0 scan+auth+assoc"
157 it enables debug messages while scanning, authenticating to
158 an access point, and associating to an access point.
165 Different wireless drivers support different debugging messages.
172 module for 802.11 protocol processing typically support
173 most of the debugging messages while devices that
174 implement parts of the 802.11 protocol in firmware do not.
176 Some debugging messages are no longer meaningful
177 because protocol processing has moved from the operating
178 system to user mode programs such as
181 .Xr wpa_supplicant 8 .
