airport [interface ] [-Ixh] [-P --password=ppp --aaa]] [verb] [prefKeyword [={YES|NO|value}]

If interface is not specified, uses the first AirPort interface on the system.
If nonexistant interface is specified (example en1) NO error message is displayed, help is displayed.

prefs

If specified with no key value pairs, displays a subset of preferences for the specified interface.

logger

Monitor the driver's logging facility.

sniff

If a channel number is specified, airportd will attempt to configure the interface to use that channel before it begins sniffing 802.11 frames. Captures files are saved to /tmp. Requires super user privileges.

debug

~~Enable debug logging, a setting is enabled by prefixing it with a '+', and disabled by prefixing it with a '-'.~~
