perfSONAR User Q&A and Other Discussion

["Roderick Mooi" <>]

Hi Ben

I've also found that the Mesh Configurator can be used to schedule tests for 
these kinds of scenarios. It's also simpler than the steps at 
https://code.google.com/p/perfsonar-ps/wiki/ToolkitDualInterfaceConfig

Have a look in the 

 archives for the mail thread "Multiple interfaces on perfSONAR node" for 
more information... (link: 
https://lists.internet2.edu/sympa/arc/performance-node-users/2013-11/msg00027.html)

Regards,

Roderick
