perfSONAR User Q&A and Other Discussion

[Michael Johnson <>]

Hi,

That's very odd, I haven't seen this before. Your CLI iperf tests may be using a different protocol (TCP vs UDP), or maybe the mesh is iperf2 and your manual tests use iperf3 (or vice versa)?

If your toolkit host is public, can you share a link to it? I would be curious to see whether these results are wrong in the database, or if they're being charted incorrectly for some reason.

Thanks,

Hi,

I've got a toolkit setup with a mesh configuration to keep an eye on the network performance of our worldwide WAN.

Most of the test are running as they should and reporting the correct values.

Although two of my sites are reporting over the 100mbps speeds, while the local links are 100mbps.

Site1:

Site2

As you can see they are reporting over the 100mbps for these sites which isn't correct.

These are all European sites, going to my HQ toolkit server. But the rest of the 15 sites connected to the same server are working fine.

When I run a manual iPerf test the bandwidth values are within the correct values so there must be something wrong with the config of these two toolkits.

If anyone has an idea where I should start looking or what to do, it would be appreciated!

Thanks
