perfSONAR User Q&A and Other Discussion

[Andrew Lake <>]

Hi Ben,

Unfortunately the toolkit doesn't directly support multiple interfaces at the 
moment. It only looks at one address for the host. The FAQ here has some more 
details and a link to a page that describes a way to use multiple interfaces 
involving some special wrapper scripts for bwctl and owamp that may help: 
http://psps.perfsonar.net/toolkit/FAQs.html#Q59

The configuration is a bit involved and we are looking at better ways to do 
this in the future, but currently the above method has yielded some success 
for people wishing to do similar things.

Thanks,
Andy
