IP Aliasing Configuration

If a system is configured for use with multiple IP addresses, it may be necessary to select which IP addresses should be used during a load test. These IP addresses may be specific per network adapter, or the workstation may be specifically configured for multiple IP addresses.

Configuring the local Workstation

The IP Aliasing preference page may be accessed by selecting Window → Preferences → Web Performance → IPAliasing.

This page will display a list of the IP addresses available on the current system, which may be used to reach other servers. By default, Web Performance Load Tester is configured to use the default configuration, specified by the Operating System. However, if more control is desired, then the dialog can be set to "Use Selected Interfaces", and the checked IP addresses will be used. If the workstation has multiple IPs, then can be used to allow different users to originate from different IPs on the same workstation. Further, if some of the IP addresses are not appropriate for load testing (eg. a wireless connection) in the current environment, then those addresses may be unselected.

Remote Engine Configuration

The IP Aliasing configuration may also be specified for Remote Engines. In the Engines View, simply select an Engine that you would like to configure, and press the "Configure IPs" button. A dialog is displayed for the Engine's current IP aliasing configuration, which apply in the same way as outlined above.
