WPA and WPA2 use individual keys for each device. You will need to do this for all machines whose traffic you want to see. One way to do this is to put the machine to sleep (for smartphones and tablets, "turning off" the machine puts it to sleep) before you start the capture, start the capture, and then wake the machine up. In order to capture the handshake for a machine, you will need to force the machine to (re-)join the network while the capture is in progress. You can use the display filter eapol to locate EAPOL packets in your capture. Unless all four handshake packets are present for the session you're trying to decrypt, Wireshark won't be able to decrypt the traffic. WPA and WPA2 use keys derived from an EAPOL handshake, which occurs when a machine joins a Wi-Fi network, to encrypt traffic. As a result you have to escape the percent characters themselves using %25.

The WPA passphrase and SSID preferences let you encode non-printable or otherwise troublesome characters using URI-style percent escapes, e.g.

You may have to toggle Assume Packets Have FCS and Ignore the Protection bit depending on how your 802.11 driver delivers frames. GotchasĪlong with decryption keys there are other preference settings that affect decryption. Driver will pass the keys on to the AirPcap adapter so that 802.11 traffic is decrypted before it's passed on to Wireshark. Selecting Wireshark uses Wireshark's built-in decryption features. As shown in the window you can select between three decryption modes: None, Wireshark, and Driver: This will open the decryption key managment window. Click on the Decryption Keys… button on the toolbar: If the toolbar isn't visible, you can show it by selecting View->Wireless Toolbar.

If you are using the Windows version of Wireshark and you have an AirPcap adapter you can add decryption keys using the wireless toolbar.

wpa-psk The key is parsed as a raw pre-shared WPA key.

This may not work for captures taken in busy environments, since the last-seen SSID may not be correct. You can optionally omit the colon and SSID, and Wireshark will try to decrypt packets using the last-seen SSID.

wpa-pwd The password and SSID are used to create a raw pre-shared WPA key.

wep The key must be provided as a string of hexadecimal numbers, with or without colons, and will be parsed as a WEP key.Ī1:b2:c3:d4:e5 0102030405060708090a0b0c0d.

When you click the + button to add a new key, there are three key types you can choose from: wep, wpa-pwd, and wpa-psk:

You should see a window that looks like this: You should see a window that looks like this:Ĭlick on the "Edit…" button next to "Decryption Keys" to add keys. Go to Edit->Preferences->Protocols->IEEE 802.11. You can add decryption keys using Wireshark's 802.11 preferences or by using the wireless toolbar. WPA/WPA2 enterprise mode decryption works also since Wireshark 2.0, with some limitations. Once you identify the source of the traffic causing the burst you can do some further research into what application(s) are causing the spike and continue the troubleshooting.Wireshark can decrypt WEP and WPA/WPA2 in pre-shared (or personal) mode.

If you click on the top of the spike in the graph, the main Wireshark window will jump to that packet. 001), the shorter the time, the more accurate it will be.Ĭhange the “Y-Axis” Unit from the default “Packets/Tick” to “Bits/Tick” because that is the unit the interface is reporting Wireshark will let you click on any point in the graph to view the corresponding packet in the capture. By default the X Axis is set to a “Tick Interval” of 1 second but if no drops are seen on that interval is best to select an interval lower than 1 second (.01 or. Next we need to look at our X and Y Axis values. Start the capture and let it run long enough to try to get the suspected burst event (if you have an approximate time in which the event occurs that would narrow the time of the capture) Set ethernet-switching-options analyzer JTAC output interface xe-0/0/47.0 set ethernet-switching-options analyzer JTAC input egress interface xe-0/0/0.0 The information below will help identify if the output drops on the interface are occurring due to spikes of traffic.Ī traffic burst can cause output drops on the interfaces even when the interface is not being utilized at the maximum capacity.įor us to identify what kind of traffic and which packets are being dropped we are going to use a port mirroring session and check out the capture on Wireshark. A microburst of traffic can overload the physical link capacity and buffer space on a scale of milliseconds causing drops even though the overall utilization is low. If you are seeing output drops increment, but the overall traffic utilization of that interface is low, you are most likely experiencing some type of bursty traffic. Output drops are usually caused by congested interfaces.
