config ap sniff 802.11a

To enable or disable sniffing on a Cisco 1000 Series lightweight access point radio, use the config ap 
sniff 802.11a command.
When the sniffer feature is enabled on a Cisco 1000 Series lightweight access point, it starts sniffing the 
signal on the given channel. It captures and forwards all the packets to the remote computer that runs 
airopeek, a packet analyzer for IEEE 802.11 wireless LANs. It includes information on timestamp, signal 
strength, packet size and so on.
Before a Cisco 1000 Series lightweight access point can act as a sniffer, a remote computer that runs 
Airopeek must be set up so that it can receive packets sent by the Cisco 1000 Series lightweight access 
point. After the Airopeek installation, copy the following .dll files to the location where airopeek is 
installed.

•

socket.dll file to the Plug-ins folder (Example: C:\Program Files\WildPackets\AiroPeek\Plugins)

•

socketres.dll file to the PluginRes folder (Example: C:\Program 
Files\WildPackets\AiroPeek\1033\PluginRes)
