If <destination> is "gw" then the next hop gateway for the default route is used. top Run top. packet_capture [ --device <device> ] [ --frequency <frequency> ] [ --ht-location <above|below> ] [ --monitor-connection-on <monitored_device> ] Start packet capture. Start a device-based capture on <device>, or do an over-the-air capture on <frequency> with an optionally provided HT channel location. An over-the-air capture can also be initiated using the channel parameters of a currently connected <monitored_device>.
