step 4 flow name was wrongly mentioned actual flow name is "UcastOut_1056_4_fa:16:3e:3d:e8:a7"

Flows are identified by match, priority and table, so when sent to OVS, it thinks that are basically same flows, because only difference in them is action, so what openflowplugin does is, that it sends first flow to device, then sends second flow, but this second flow will replace first flow.

So I think this can be closed then, because it is correct behaviour, right? Maybe it is a bit confusing to have both flows still in config tho.

No response long time assume the bug was fixed. Closing
