[ovs-discuss] Question about behavior of flows with priority=0

Hi,

We have the OVS running with the following flows configured:

1.
Table=0,priority=0,in_port=65534,dl_src=08:00:27:a5:50:f9,dl_dst=08:00:2
7:66:d8:6e actions=output:1
2.	Table=0,priority=0,in_port=1,dl_src=08:00:27:
66:d8:6e,dl_dst=08:00:27:a5:50:f9 actions=output:LOCAL
3.	Table=0,priority=100,icmp,in_port=65534 actions=CONTROLLER:32767
4.	Table=0,priority=100,icmp,in_port=1 actions=CONTROLLER:32767

On a pkt received from port 1, for example, both rules 2 and 4 are hit.
Why is that? Since the rule #4 has a higher priority we expect it to
match and then no more processing for the specified pkt. Doesn't the OVS
work this way ?

Eventually, all these pkts are sent to the controller AND are processed
as described on rules 1 and 2.

Does the priority=0 has special meaning ? 

Regards,
Simhon Doctori
