Hi Ben, In reference to the mail dated 15.09.2014 I would like to thank you for your continued support to the team.Attached is the mail for reference.
In progress to the same ,so far we have achieved the below mentioned.Wanted to share the understanding and confirmation on the same. Case 1: Flow Added with default active version on OpenvSwitch ( OF10 ) alongwith importance ( Eviction implementation in accordance with OF1.4 ). Add Flow Command(OF10) : ovs-ofctl add-flow br0 priority=21,importance=21,action=normal Output: No Error , rule saved but with default importance( i.e zero ) rather than with the specified value by user. Dump-Flow Command(OF 10) : ovs-ofctl dump-flows br0 Output: cookie=0x0, duration=8.736s, table=0, n_packets=0, n_bytes=0, idle_age=8, priority=21 actions=NORMAL Dump-Flow Command(OF 11+) : ovs-ofctl -O OpenFlow13 dump-flows br0 Output: cookie=0x0, duration=116.980s, table=0, n_packets=6, n_bytes=546, priority=21 actions=NORMAL The understanding is ,if the flow is added by the default active version i.e OF10 , the added flow will have importance set as zero whether provided by the user or not.The same is reflected in the dump flows either via OF10 or OF11+ . If importance is zero it will not be visible in that case. Query 1: Is this handling correct or we need to throw a message to the user that "importance" is supported by a particular version only rather than making it zero. Also as we are using OF11 flow mod structure as mentioned in previous mail, will importance parameter in add-flow should be supported on 1.1+ or we have to make it OF1.4 specific only. Case 2: Flow Added with specific version on OpenvSwitch ( OF11+ ) alongwith importance (Eviction implementation in accordance with OF1.4 ). Add Flow Command(OF11+) : ovs-ofctl -O OpenFlow13 add-flow br0 priority=22,importance=22,action=drop Output: No Error , rule saved with the value provided by the user and else zero if not provided by the user. Dump-Flow Command(OF 10) : ovs-ofctl dump-flows br0 Output: (IMPORTANCE NOT VISIBLE) cookie=0x0, duration=47.841s, table=0, n_packets=2, n_bytes=182, idle_age=24, priority=22 actions=drop cookie=0x0, duration=243.481s, table=0, n_packets=6, n_bytes=546, idle_age=152, priority=21 actions=NORMAL Dump-Flow Command(OF 11+) : ovs-ofctl -O OpenFlow13 dump-flows br0 Output: (IMPORTANCE VISIBLE FOR THE FLOWS HAVING VALUE SET FOR THE FIELD) cookie=0x0, duration=141.275s, table=0, n_packets=2, n_bytes=182, importance=22, priority=22 actions=drop cookie=0x0, duration=336.915s, table=0, n_packets=6, n_bytes=546, priority=21 actions=NORMAL The understanding is,if the flow is added by a specific version (OF11+), the added flow will have importance set as the value provided by the user else zero.Now if the user dump-flows with the default version (OF10) none of the flows importance parameter will be visible even for the set one's else if dump-flows via OF11+ , the importance parameter will be visible for the flows which have the parameter set of. Query 2: Do we need to show the importance field if a flow is added by OF11+ and dump-flows via OF10. Currently we are not showing as mentioned above.Also this should also be only 1.4 specific or 1.1+ is fine. Note: On finalizing the the above mentioned approach we will be submitting the patch for the same at the earliest. Need your confirmation on the above working.
