1.if the 7th bit in the first byte of mac address is 1 means multicast(even broadcast), for example 01:00:5e:00:00:00 is a multicast address, and ff ff ff ff ff ff is an broadcast address. They both have the 7th bit with value '1'.

2. By defult, ovs has 255 tables, every table has the full-mtch-field. You can try command ovs-ofctl dump-tbles

1. that means mac address with mask
2. 20 and 21 are table id, not port number

Hi all,
i am trying to understand following openflows:

cookie=0x0, duration=93322.864s, table=1, n_packets=1336, n_bytes=151043, idle_age=18843, hard_age=65534, priority=1,dl_dst=00:00:00:00:00:00/01:00:00:00:00:00 actions=resubmit(,20)
cookie=0x0, duration=93322.76s, table=1, n_packets=212, n_bytes=17008, idle_age=19033, hard_age=65534, priority=1,dl_dst=01:00:00:00:00:00/01:00:00:00:00:00 actions=resubmit(,21)

can someone tell me what these 00:00:00:00:00:00/01:00:00:00:00:00 and 01:00:00:00:00:00/01:00:00:00:00:00 are ?

also i don't see any port 20 and 21 in ovs-ofctl dump-flows ,what do these port signifies

1(patch-int): addr:6a:9f:e1:05:8f:29

2(gre-ac10010a): addr:e2:84:db:7b:40:c9

4(gre-ac1001c9): addr:e2:fd:25:e5:0d:e5
