Hi,
From "ovs-ofctl snoop" output below, seems that when a FLOW_MOD arrives, OVS
drops ip match field when adding a new flow, only L2 info is kept. I use
"ovs-ofctl dump-flows" to list all flows, all of them don't include L3 info. I
use wireshark to observe at controller side, and see that FLOW_MOD messages
controller sends out, include ip match field. Why those info are dropped?
Thanks very much.
