Wireshark
First, download Wireshark and install it on your computer. You can download Wireshark from
https://www.wireshark.org/.
To initiate the Wireshark network analyzer tool for Microsoft Windows, follow these steps:
Step 1
On your computer, initiate the Wireshark tool.
Step 2
In the menu, click Capture > Options. A popup window appears.
Step 3
In the Interface field, select Remote. A popup window appears.
Step 4
In the Host field, enter the IP address of the WAP device.
Step 5
In the Port field, enter the port number of the WAP device. For example, enter 2002 if you used the default, or enter the
port number if you used a port other than the default.
Step 6
Click OK.
Step 7
Select the interface from which you need to capture the packets. At the Wireshark popup window, next to the IP address,
there is a drop-down menu to select the interfaces. The interface can be one of the following:
Linux bridge interface in the wap device
--rpcap://[192.168.1.220]:2002/brtrunk
Wired LAN interface
-- rpcap://[192.168.1.220]:2002/eth0
VAP0 traffic on radio 1
-- rpcap://[192.168.1.220]:2002/wlan0
802.11 traffic
-- rpcap://[192.168.1.220]:2002/radio1
At WAP361, VAP1 ~ VAP7 traffic
-- rpcap://[192.168.1.220]:2002/wlan0vap1 ~ wlan0vap7
At WAP150, VAP1 ~ VAP3 traffic
-- rpcap://[192.168.1.220]:2002/wlan0vap1 ~ wlan0vap3
You can trace up to four interfaces on the WAP device simultaneously. However, you must start a separate Wireshark
session for each interface. To initiate additional remote capture sessions, repeat the Wireshark configuration steps. No
configuration required on the WAP device.
