Dear, I've just configured a perfSONAR server for client usage.

I put tow interfaces in the same network segment, and I've added these
lines in /etc/sysctl.conf in order to avoid ARP conflicts with both
interfaces:

net.ipv4.conf.all.arp_ignore=1
net.ipv4.conf.all.arp_announce=2
net.ipv4.conf.default.arp_filter=1
net.ipv4.conf.all.arp_filter=1

After that I configured two tests selecting different interfaces:

1- Throughput against albq-pt1.es.net server, selecting eth0
2- One-way Latency against aofa-owamp.es.net server, selecting eth1

After saving te tests configuration, I get this warning in the
perfSONAR web interface:

This host is configured with both bandwidth and one-way latency tests.
Bandwidth tests can interfere with one-way latency tests.

What is the reason for this warning? Because I have two interfaces.

Pleae can you help me ?

Thanks a lot, regards !!!
