VulcanManager allows you to enable traffic capture on test ports while running a test. For both test ports (see Stateful L4-7 End-to-End Testing) used in a test, traffic is captured into two separate PCAP files. To enable this, simply go to "Run Test" tab and check the option "Capture to PCAP" as shown below.
After the test is stopped or finished, you will see the controller button changed to "Reset". If you want to download the PCAP files and view the captured traffic, do not click "Reset", otherwise the captured traffic will be deleted.
Right-click on a test port where you want to view the captured traffic, and choose "Wireshark capture"
Then, the PCAP file of that port will be downloaded from the chassis to your PC and automatically opened by Wireshark, if your PC has installed the software. You can read more about Wireshark here: https://www.wireshark.org/.
