Manual Pages  — WLANDEBUG

The wlandebug command is a tool for enabling and disabling debugging messages 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 copious 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 operation; 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 inactivity.
roam	trace station mode roaming between access points.
rate	trace transmit rate control operation.

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 not.

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