Using port binding and link aggregation
FortiTester port binding can be used to bind multiple physical ports as one logical port. The physical ports in one logical port share one network configuration, including IP address, netmask, and gateway.
This feature is useful in the following scenarios:
- To test the link aggregation feature of the DUT. A DUT might also support port binding (also called link aggregation or TRUNK). In that case, FortiTester can test this feature and its performance.
- To test 40G/100G ports of the DUT. A DUT might have some ports that have bandwidth greater than a single FortiTester port. To test such port performance, you can bind multiple FortiTester ports as one logical port and connect to a switch to transfer traffic with a DUT. For example, a FortiTester appliance can bind four 10G ports as one to test a 40G port in DUT via a 10G/40G switch.
FortiTester averages traffic on physical ports that belong to one logical port.
To change the port binding:
- When you create a test case, in its Network Settings pane, click on the Optional Port Binding link.
- Click Add, under Network Settings.
- Configure the settings. You can configure the number of bond interfaces and member ports, as well as the bond type.
- Click Save.
