• Client Filter MAC Address—Specifies the MAC address for WLAN client filtering.
NOTE The MAC filter is active only when a capture is performed on an 802.11
interface.
• 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.
STEP 2 Depending on the selected method, refer to the steps in the Local Packet Capture or Remote
Packet Capture section to continue.
NOTE 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.
