9.4 Notes on measuring flows (packets) per second
For measuring flows-per-second for performance testing, the learn.IP option in
com.hp.sdn.ctl.nodemgr.impl.NodeManager (under Configurations/Component) in the controller
GUI should be set to "false" due to the additional processing required. (The default setting is "true".)
1. In the controller web interface, select the “Configurations” option.
2. Select the com.hp.sdn.ctl.nodemgr.impl.NodeManager component.
3. Click on the Modify button.
Figure 77 Display the learn.ip option
4. Enter false in the learn.ip Value field.
Figure 78 Set learn.ip to “false”
5. Click on the Apply button to set the new learn.ip configuration and close the window.
NOTE: When flow measurement tasks are complete, return the learn.ip setting to its default “true”
setting. Flow measurement results may vary based on the type of server used for the controller,
and on the server configuration.
