perfSONAR User Q&A and Other Discussion

["Andrew Lake" <>]

Hi Murilo,

Currently BWCTL does not have this type of limits. It makes sense why you would want to do that though, and I suspect it will become a more common request since the dual inetrface route is becoming more common and BWCTL supports more tools like ping/owping now. There is a big effort currently to write a new version of bwctl, BWCTL 2.0, and part of the motivation for that effort is to allow new types of limits in the future. Don’t take that as a promise that the initial version of BWCTL will have support for this exact limit day one, but it is something that has been talked about. A preview version of BWCTL 2.0 will  be included with a new release candidate of the perfSONAR toolkit that should be available in about a week. It does not have support for this limit yet. I added your request to https://github.com/perfsonar/bwctl/issues/8 so we don’t forget about it as we work toward a final release, and I think it will be an important and useful feature in the future. 

Thanks,

Andy

Hello,

I asked this because I would like to guarantee that when is a OWAMP test, for instance, comes to interface A and IPERF3 test comes to interface B.

I would like to ensure that owamp test doesn't comes to interface B. We would like to have a way to not conflict between distinct type of tests.

How in older version bwctl just worked for IPERF, I just dedicated interface A for bwctl and interface B for ping/owamp/traceroute.

We were doing it using linux vrf.

Now, how bwctl interporates other tools, it doesn't isolate interfaces for each kind of test.

This was the reason why I asked about limiting tests on limits.

Any other suggestion how to do it?

Hope I do myself explainable.

Thanks in advance,

Hello,

I am wondering if there is a way to configure BWCTL limits to limit bwctl to anwers to one specific interface to ping and to another specific interface to traceroute, for example.

I was thinking that there would be a way to do it by bwctl limits.

Do you know if that is possible?

Is this something you can't do with iptables?
