Hello,
I'm experiencing packets loss on OpenvSwitch host during transmission to
vxlan port under higher traffic load.
Some statistics from 2 machines are here (30 seconds run):
10.10.12.148-ens224-TX 6000025 100 %, 2130008249 bytes
10.10.12.150-ens224-RX 5999429 99 %, 2129796705 bytes
10.10.12.150-vxlan_sys_4789-TX 5641293 94 %, 1923680913 bytes
10.10.12.148 - is traffic generator machine
10.10.12.150 - is OvS host
So as you can see about 5% of traffic is lost on OvS. Does anybody have
a clue why this is happening?
More configuration details are below.
Thank you in advance for any help,
Miroslav
