is used to set a list of addresses in a wireless network interface and
to read back quality of link information for each of those. This
information is the same as the one available in
: quality of the link, signal strength and noise level.
This information is updated each time a new packet is received, so
each address of the list add some overhead in the driver.
Note the this functionality work only for node part of the current
You may set any number of addresses up to 8.
- DNSNAME | IPADDR
Set an IP address, or in some cases a DNS name (using the name
resolver). As the hardware work with hardware addresses,
will translate this IP address through
In some case, this address might not be in the ARP cache and
will fail. In those case,
this name/address and retry.
Set a hardware (MAC) address (this address is not translated & checked
like the IP one). The address must contain a colon
to be recognised as a hardware address.
Add the new set of addresses at the end of the current list instead of
replacing it. The address list is unique for each device, so each user
should use this option to avoid conflicts.
Remove the current list of addresses and disable the spy functionality
signal strength threshold for the iwspy event (for driver that support
Every time the signal strengh for any of the address monitored
with iwspy goes lower than the low threshold or goes higher than the
high threshold, a Wireless Event will be generated.
This can be used to monitor link outages without having to run iwspy

signal strength threshold for the iwspy event.
