Starting a Traffic Replay test
FortiTester tests user-defined scenarios by replaying pcap files. Typically, pcap files are generated by programs like tcpdump or Wireshark.
Note: The Traffic Replay test is available only in Standalone work mode.
Before you begin:
- You must create pcap files that can be replayed. Only IPv4 traffic is supported. Maximum file size is 200MB.
To start a Traffic Replay test:
- Go to Cases > Performance Testing > Replay > Traffic to display the test case summary page.
- Click Add to display the Select case options dialog box.
- In the popup dialog, for the Network Config option, select the network template you have created in Cases > Security Testing > Objects > Networks. Then the network related options will automatically be filled. See Using network configuration templates for how to create a network template.
- Select a Certificate Group if applicable.
- Click OK to continue.
- Configure the test case options described in Traffic Replay Test Case configuration.
- Click Start to run the test case.
FortiTester saves the configuration automatically so you can run the test again later. You can also click Save to save the test case without running it.

Tip: You can also copy an existing case, and change its settings to create a new case. In the case list, click Clone to clone the configuration. Only the case name is different from the original case. |
Traffic Replay Test Case configuration
| Settings | Guidelines |
|---|---|
| Basic Information | |
| Name | Specify the case name, or just use the default. The name appears in the list of test cases. |
| Ping Server Timeout | If a FortiTester connects to a DUT via a switch, the switch might cause a ping timeout, resulting in the test case failing to run. If this occurs, increase the timeout. The default is 15 seconds. The valid range is 0 to 600. Note: You can disable this end-to-end connectivity test by entering a setting of 0. If the DUT is unable to return packets, it is recommended you do so. |
| Number of Samples | Select the number of samples. The default is 20, which means the web UI will show the last 20 sample data (about 20 seconds) in the test case running page. You can select 20, 60, or 120. |
|
Script Config |
Select the script that will run before/after the test. To create a script, see Using script object templates. |
| Steady Duration | Specify the test duration. The default is 10 minutes. The test stops automatically after the duration you specify. |
| Stopping Status in Second | The maximum time out in seconds allotted for FortiTester to close all TCP connections after the test finishes. |
|
DNS Host Group |
Select the DNS host group to look up the IP address of a domain name. To create a DNS host group, see Creating DNS host group. |
|
DUT Monitor |
Select to monitor a FortiGate device under test (DUT). If selected, you can monitor the DUT from the DUT Monitor tab on the management interface. To create a DUT monitoring, see Using DUT monitoring. |
| Network Settings If you have selected a network config template, the network settings automatically inherit the configurations in the template. See Using network configuration templates for the description of network settings. |
|
| Load | |
| Loops | Number of times to play the pcap file. 0 means as many as possible. |
| Input Pcap | Select a pcap file to send. Note the uploaded files can be used for future cases. |
| Client/Server Network | |
| Network MTU | The maximum transmission unit size. |
| Client Limit | |
| Bandwidth | Bandwidth in Mbps. The default is 0, which means the device will send traffic as fast as possible. |
| Server Limit | |
| Bandwidth | Bandwidth in Mbps. The default is 0, which means the device will send traffic as fast as possible. |
