Yes, we find this from capture-loss.log. It used to be very low. But after upgrade 2.3 today, it jumps to 67%

Inbound and outbound merges

You're determining that number from capture-loss.log or something else?

Did you mean that it merges the traffic?
> We recently upgrade bro from 2.2 to 2.3 The capture loss used to be very low on 2.2. But the wried.log remain the same. Just wondering if software bridge setting works in this situation?
Yeah, that should work fine. It sounds like you might want to come up with a solution to your packet loss first. Unfortunately I can't give you an answer without knowing more about your network and what your deploy looks like. In most cases, 2.3 should actually be more efficient than 2.2. There was some work done around identifying some major inefficiencies and addressing them.
