-.Sh NAME
-.Nm wlandebug
-.Nd "set/query 802.11 wireless debugging messages"
-.Sh SYNOPSIS
-.Nm
-.Op Fl d | Fl i Ar ifnet
-.Op Fl flag|+flag Ar ...
-.Sh DESCRIPTION
-The
-.Nm
-command is a tool for enabling and disabling
-debugging messages in the
-.Xr wlan 4
-module.
-Running
-.Nm
-without any options will display the current messages
-enabled for the specified network interface
-(by default, ``ath0').
-The default debugging level for new interfaces can be set
-by specifying the
-.Fl d
-option.
-When run as the super-user
-.Nm
-can be used to enable and/or disable debugging messages.
-.Pp
-To enable debugging messages of a certain
-.Ar type
-use
-.Ar +type ;
-to disable such messages use
-.Ar -type .
-Multiple messages can be enabled and disabled with a single command.
-.Pp
-Messages are organized in the following groups:
-.Bl -tag -width ".Ar dumppkts"
-.It Ar debug
-general debugging facilities; equivalent to setting the debug
-parameter with
-.Xr ifconfig 8 .
-.It Ar dumppkts
-dump packet contents on transmit and receive.
-.It Ar crypto
-crypto-related work.
-.It Ar input
-errors encountered during input handling.
-.It Ar xrate
-extended rate set handling (for 802.11g).
-.It Ar elemid
-information element processing in 802.11 management frames.
-.It Ar node
-management of per-station state.
-.It Ar assoc
-802.11 station association processing; particularly useful to
-see when stations join and leave a BSS.
-.It Ar auth
-802.11 station authentication processing.
-.It Ar scan
-scanning operation; especially useful for debugging problems
-with not locating an access point.
-.It Ar output
-errors encountered during output handling.
-.It Ar state
-.Xr wlan 4
-state machine operation.
-.It Ar power
-802.11 power save operation; in hostap mode this enables
-copious information about buffered frames for stations operating
-in power save mode.
-.It Ar hwmp
-trace operation of Hybrid Wireless Mesh Protocol processing.
-.It Ar dot1xsm
-802.1x state machine operation; not presently meaningful as 802.1x protocol
-support is implemented in user mode by the
-.Xr hostapd 8
-program.
-.It Ar 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
-.Xr hostapd 8
-program.
-.It Ar raddump
-dump packets exchanged with the radius backend for 802.1x operation;
-not presently meaningful as 802.1x protocol
-support is implemented in user mode by the
-.Xr hostapd 8
-program.
-.It Ar mesh
-trace operation of 802.11s mesh protocol processing.
-.It Ar wpa
-trace operation of the WPA protocol;
-only partly meaningful as WPA protocol
-support is mostly implemented in user mode by the
-.Xr hostapd 8
-and
-.Xr wpa_supplicant 8
-programs.
-.It Ar acl
-trace operation of the Access Control List (ACL) support; see
-.Xr wlan_acl 4
-for more details.
-.It Ar wme
-trace operation of WME/WMM protocol processing.
-.It Ar superg
-trace operation of Atheros SuperG protocol processing.
-.It Ar doth
-trace operation of IEEE 802.11h protocol processing.
-.It Ar inact
-trace station inactivity processing; in particular,
-show when stations associated to an access point are dropped due to
-inactivity.
-.It Ar roam
-trace station mode roaming between access points.
-.It Ar rate
-trace transmit rate control operation.
-.El
-.Sh EXAMPLES
-The following might be used to debug basic station mode operation:
-.Pp
-.Dl "wlandebug -i ral0 scan+auth+assoc"
-.Pp
-it enables debug messages while scanning, authenticating to
-an access point, and associating to an access point.
-.Sh SEE ALSO
-.Xr ifconfig 8 ,
-.Xr wlanstats 8 ,
-.Xr athdebug 8 ,
-.Xr athstats 8 .
-.Sh NOTES
-Different wireless drivers support different debugging messages.
-Drivers such as
-.Xr ath 4
-and
-.Xr ral 4
-that depend on the
-.Xr 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 not.
-.Pp
-Some debugging messages are no longer meaningful
-because protocol processing has moved from the operating
-system to user mode programs such as
-.Xr hostapd 8
-and
-.Xr wpa_supplicant 8 .
