mode operation.

•

Radio Client Filter—Enables or disables the WLAN client filter to capture 
only frames that are transmitted to, or received from, a WLAN client with a 
specified MAC address.

•

Packet Capture Method—Select one of these options:

-

Local File—Captured packets are stored in a file on the WAP device. 

-

Remote—Captured packets are redirected in real time to an external 
computer running the Wireshark tool.

Depending on the selected method, refer to the steps in the Local Packet Capture 
or Remote Packet Capture section to continue.

Changes to packet capture configuration parameters take affect after packet 
capture is restarted. Modifying the parameters while the packet capture is running 
does not affect the current packet capture session. To begin using new parameter 
values, an existing packet capture session must be stopped and restarted.

To initiate a local packet capture:

Ensure that Local File is selected for the Packet Capture Method.

Configure these parameters:
