Hi, all
I am a newbee to open vswitch community. I am interested on hot trending SDN and OVS implementation. I have a question about wildcarding the match fields. ? If we don't specify some match field (e.g. tcp_src_port), it will wildcard and matching all flows on this field. However, is it possible to match the field, tcp_src_port for instance, for a range of numbers in one flowmod? I checked openflow specification and found that there was only mask for eth_addr and ip_addr and no mask for other fields like tcp_port. Does it mean if i want to match tcp_port for a range of numbers, the only way is to mod several rules? Thank you in advance for any answers. Best regards Chenfay
