Packet Capture

Cisco WAP131 and WAP351 Administration Guide

57

In promiscuous mode, the radio receives all traffic on the channel, including 
traffic that is not destined to the WAP device. While the radio is operating in 
promiscuous mode, it continues serving associated clients. Packets not 
destined to the WAP device are not forwarded.

As soon as the capture is completed, the radio reverts to nonpromiscuous 
mode operation.

•

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

•

Client Filter MAC Address—Specifies the MAC address for WLAN client 
filtering. Note that the MAC filter is active only when a capture is performed 
on an 802.11 interface.

•

Packet Capture Method—Choose 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 

 section to continue. 

Changes to the packet capture configuration parameters take affect after the 
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:

Select Administration > Packet Capture. 

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

Configure these parameters:
