wlanconfig - Create, destroy and manipulate madwifi VAPs

CONTENTS

wlanconfig <vap> create wlandev <base device> wlanmode <mode>

wlanconfig <vap> destroy wlanconfig <vap> list <list item>

The current MadWifi driver supports multiple APs and concurrent AP/Station mode operation on the same device. The devices are restricted to using the same underlying hardware, thus are limited to coexisting on the same channel and using the same physical layer features. Each instance of an AP or station is called a Virtual AP (or VAP). Each VAP can be in either AP mode, Station Mode, "special" station mode, and Monitor mode. Every VAP has an associated underlying base device which is created when the driver is loaded.

<vap> create [nounit] wlandev <base device> wlanmode <mode> [bssid|-bssid] [nosbeacon]
	Create the interface <vap> using the specified <base device> and <mode>. <vap> can either be a full interface name (e.g. ’ath0’), or just the suffix (e.g. ’ath’), in which case, the kernel will automatically append the next vacant integer. [nounit] will turn off the automatic integer increments.
<vap> destroy
	Removes the given VAP interface. You must specify the full interface name. I.e ’ath0’ rather than just ’ath’.
<vap> list <list item>
	Show information about connected peers, keys, channels etc.

ahdemo	Create the station in ad-hoc demo (aka pseudo IBSS) mode.
adhoc	Create the station in ad-hoc mode.
ap	Create the VAP in AP mode.
monitor
	Create the station in monitor mode.
sta	Create the VAP in station mode.
wds	Create the station in WDS mode.

bssid	Create the VAP using a different MAC address from the underlying device.
-bssid	Create the VAP using the MAC address of the underlying device.
nosbeacon
	When both station VAPS and AP VAPs coexist, the station should be created with the nosbeacon flag set in order to disable the use of hardware beacon times for the station.

sta or no parameters.
	Show information on associated stations.
scan or ap
	List all visible stations.
chan or freq
	List all channels and frequencies.
active	List all available channels and frequencies.
keys	List all of the keys associated with the VAP
caps	List the capabilities of the given VAP.
wme	List WME (Wireless multimedia extensions, aka WMM) parameters.

wlanconfig ath create wlandev wifi0 wlanmode sta
	Create a station mode VAP, using wifi0 as the underlying device. The interface wil be called athN, where N is the first free integer. The MAC address will be the same as the underlying device.
wlanconfig ath0 create wlandev wifi0 wlanmode sta
	Create a station mode VAP (ath0) using wifi0 as the underlying device. The MAC address will be the same as the underlying device.
wlanconfig ath0 create wlandev wifi0 wlanmode ap
	wlanconfig ath1 create wlandev wifi0 wlanmode sta nosbeacon   Create both an AP and a station mode interface.   wlanconfig ath0 destroy   Destroy VAP ath0. wlanconfig ath0 list scan   Scan for local stations and access points. wlanconfig ath0 create wlandev wifi0 wlanmode ap   wlanconfig ath1 create wlandev wifi0 wlanmode wds iwconfig ath0 essid "Normal atheros AP" channel 1 iwpriv ath1 wds_add <mac of the peer wds ap> iwpriv ath1 wds 1 ifconfig ath1 up ifconfig ath0 up brctl addbr br0 brctl addif br0 ath1 brctl addif br0 ath0 ifconfig br0 up Create a WDS bridge.
