6. Refer to the following packet capture data for RF domain member connected wireless clients:

   RF Domain	Displays the administrator assigned name of the selected RF domain used for wireless client packet captures. RF domains allow administrators to assign configuration data to multiple devices deployed in a common coverage area, such as in a floor, building or site.
   Send Data To	Use the Send Data To drop-down menu to select where wireless client packet capture messages are collected. If Screen is selected, client packet capture data is sent to the Live Wireless Debug Events window at the bottom of the dialog window. If File is selected, the file location must be specified in the File Location section of the window.
   Dropped	Select Dropped to create an event entry each time a packet is dropped from a client connected to a RF domain member device. Use this information to assess whether a particular RF domain is experiencing high levels of dropped packets that may require administration to distribute client connections more evenly.
   Interface	Select Interface to specify packet capture on a specific interface on the current RF domain. If Interface is selected, specify the interface name and number and specify a packet direction
   On a Radio (802.11)	Select On a Radio (802.11) to capture packets only on 802.11 radios. If selecting this option, specify which radios should be used and specify a packet direction.
   Filter (MAC, IP, Protocol, Port)	Filter packet captures based on specific criteria. Select one or more of the following and specify the relevant information: Filter by MAC Filter By IP IP Protocol Port
   Maximum Packet Count	Set the Maximum Packet Count to limit the number of packets captured for trending. Set this value between 1 - 10000 packets, with a default value of 200.

7. Select Start to begin the packet capture.
   Information sent to the screen displays in the lower portion of the window. If the data is being sent to a file, that file populates with the packet capture information. If you have set a long message capture duration and want to end the capture early, select Stop.
