Starting a Traffic Replay test

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:
  1. In Performance Testing, expand Replay and click Traffic.
  2. Click Create New.
  3. Configure the network or select a network template. See Using network configuration templates for how to create a network template.
  4. Select a Certificate Group, if applicable.
  5. Click OK.
  6. Configure the test case options described below.
  7. 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 1: You can 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.

Tip 2: You can add or edit a comment when the test is running. This comment can be used to search for the test result in the Results page. This is useful especially when the test runs for a long time.

Traffic Replay test case options

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.
