You say that it depends the expire mechanism, the "expire" function in the ofproto-dpif.c, delete the flow entries which have been idle too long. So if the flow entry is always used, it won't be deleted. In some scenario, it will exhaust the memory resource. And in handle_table_stats_request function, reply the capability of flow table is 1000000(max_entries), But it has not been used in anywhere. _______________________________________________ discuss mailing list discuss@openvswitch.org http://openvswitch.org/mailman/listinfo/discuss
