WLANDEBUG(8)		FreeBSD	System Manager's Manual		  WLANDEBUG(8)

     wlandebug -- set/query 802.11 wireless debugging messages

     wlandebug [-d | -i	ifnet] [-flag|+flag ...]

     The wlandebug command is a	tool for enabling and disabling	debugging mes-
     sages in the wlan(4) module.  Running wlandebug without any options will
     display the current messages enabled for the specified network interface
     (by default, ``wlan0').  The default debugging level for new interfaces
     can be set	by specifying the -d option.  When run as the super-user
     wlandebug can be used to enable and/or disable debugging messages.

     To	enable debugging messages of a certain type use	+type; to disable such
     messages use -type.  Multiple messages can	be enabled and disabled	with a
     single command.

     Messages are organized in the following groups:

     debug     general debugging facilities; equivalent	to setting the debug
	       parameter with ifconfig(8).

     dumppkts  dump packet contents on transmit	and receive.

     crypto    crypto-related work.

     input     errors encountered during input handling.

     xrate     extended	rate set handling (for 802.11g).

     elemid    information element processing in 802.11	management frames.

     node      management of per-station state.

     assoc     802.11 station association processing; particularly useful to
	       see when	stations join and leave	a BSS.

     auth      802.11 station authentication processing.

     scan      scanning	operation; especially useful for debugging problems
	       with not	locating an access point.

     output    errors encountered during output	handling.

     state     wlan(4) state machine operation.

     power     802.11 power save operation; in hostap mode this	enables	copi-
	       ous information about buffered frames for stations operating in
	       power save mode.

     hwmp      trace operation of Hybrid Wireless Mesh Protocol	processing.

     dot1xsm   802.1x state machine operation; not presently meaningful	as
	       802.1x protocol support is implemented in user mode by the
	       hostapd(8) program.

     radius    radius backend operation	as it relates to 802.1x	operation; not
	       presently meaningful as 802.1x protocol support is implemented
	       in user mode by the hostapd(8) program.

     raddump   dump packets exchanged with the radius backend for 802.1x oper-
	       ation; not presently meaningful as 802.1x protocol support is
	       implemented in user mode	by the hostapd(8) program.

     mesh      trace operation of 802.11s mesh protocol	processing.

     wpa       trace operation of the WPA protocol; only partly	meaningful as
	       WPA protocol support is mostly implemented in user mode by the
	       hostapd(8) and wpa_supplicant(8)	programs.

     acl       trace operation of the Access Control List (ACL)	support; see
	       wlan_acl(4) for more details.

     wme       trace operation of WME/WMM protocol processing.

     superg    trace operation of Atheros SuperG protocol processing.

     doth      trace operation of IEEE 802.11h protocol	processing.

     inact     trace station inactivity	processing; in particular, show	when
	       stations	associated to an access	point are dropped due to inac-

     roam      trace station mode roaming between access points.

     rate      trace transmit rate control operation.

     The following might be used to debug basic	station	mode operation:

	   wlandebug -i	wlan1 scan+auth+assoc

     it	enables	debug messages while scanning, authenticating to an access
     point, and	associating to an access point.

     athdebug(8), athstats(8), ifconfig(8), wlanstats(8)

     Different wireless	drivers	support	different debugging messages.  Drivers
     such as ath(4) and	ral(4) that depend on the wlan(4) module for 802.11
     protocol processing typically support most	of the debugging messages
     while devices that	implement parts	of the 802.11 protocol in firmware do

     Some debugging messages are no longer meaningful because protocol pro-
     cessing has moved from the	operating system to user mode programs such as
     hostapd(8)	and wpa_supplicant(8).
