Hi,
I apologize if my question seems rudimentary but is there a way to add
bridges to different datapaths? From what I understand, in the previous
versions of OVS, datapath and bridges were analogous to each other. Now any
new bridge seems to go to the same datapath i.e. ovs-system.
Is there a wa
o benchmark OVS-1.7.1 in terms of
throughput when the flow table has a million configured flows.
Looking forward to seeing the new enhancements. Thank you for the timely
reply and all the help.
Regards.

provided a patch for increasing the buffer space to 1MB to resolve
this issue. It is already 1 MB in OVS-1.7.1. So should I increase it
further? Is this something to be concerned about? Any heads up would be
appreciated.
Regards.

Thanks for the explanation Justin.
I have lowered their log levels and I don't these warnings anymore. Thanks
for the help.

These warnings are only generated when traffic hits the bridge at a high
rate. Is it normal for OVS to show these warnings/information messages when
dealing with high data rate traffic? Is there a way to hide or minimize
them?

Yea sure. Let me first look if memory is indeed an issue with the current
version for me, if yes then I'd switch to the newer one available at master.
Thanks for the help and suggestion.
Regards.

Memory was the issue. There was only 303 MB of RAM left and hence the crash.
Thank you for the help Ben.
Much appreciated.

Am I missing something here? Or have have I overburdened the switch with
flows so that it crashes?

Hello,
I was trying to push a million flows on br0 using the following loop in a
bash script:
for((i=0; i<1000; i++))
do
src_port=$((65535 - $i))
for((j=0; j<1000; j++))
do
dst_port=$((65535 - $j))
ovs-ofctl add-flow br0
priority=65535,idle_t
-- set interface vx1 type=vxlan
options:remote_ip=192.168.0.101, options:key=100
They both work fine for me.
