Sorry looks like I was not clear on the definitions. I thought overlapping and identical are the same. Consider this example. These are identical then? So, if Controller sent RULE 2 before RULE 1 expired, RULE 2 will replace RULE 1? *RULE 1:* ADD priority=0,in_port=21,vlan_tci=0x0000,dl_src=00:24:e8:cc:f9:ca,dl_dst=00:14:d1:1b:94:21 cookie:0x20000000000000 idle:5 flags:0x1 actions=output:23 *RULE 2:* ADD priority=0,in_port=21,vlan_tci=0x0000,dl_src=00:24:e8:cc:f9:ca,dl_dst=00:14:d1:1b:94:21 cookie:0x20000000000000 idle:5 flags:0x1 actions=output:23 > If they are identical, rule 2 replaces rule > 1.
