Hi
I tested with the below mentioned topology, having a broadcast flow whose actions were set to broadcast group ID. When I tried to ping from host h1 to h2, ARP request packet is sent out to only one port and not to all ports. We have created a group of type "all" with the egress ports set to port3 and port4. The expectation here is that any flow that uses this group has to egress the traffic on both the ports. In the below tcpdump capture you can see that ARP-Request traffic goes out of port4 and not thro' port3. This seems to be a bug and I request your inputs. mininet> net h1 h1-eth0:s1-eth1 h1-eth1:s1-eth2 h2 h2-eth0:s1-eth3 h3 h3-eth0:s1-eth4 s1 lo: s1-eth1:h1-eth0 s1-eth2:h1-eth1 s1-eth3:h2-eth0 s1-eth4:h3-eth0 c0 [mininet@opendaylight test]\>sudo ovs-ofctl dump-groups s1 -O OpenFlow13 OFPST_GROUP_DESC reply (OF1.3) (xid=0x2): group_id=32399,type=all,bucket=weight:0,actions=output:3,output:4 group_id=28326,type=select,bucket=weight:0,actions=output:1,output:2 mininet@opendaylight test]\>sudo ovs-ofctl dump-flows s1 -O OpenFlow13 OFPST_FLOW reply (OF1.3) (xid=0x2): cookie=0x0, duration=4310.355s, table=0, n_packets=2790, n_bytes=117180, dl_dst=ff:ff:ff:ff:ff:ff actions=group:32399 cookie=0x3000000000000008, duration=4496.507s, table=0, n_packets=308, n_bytes=38192, priority=5,dl_dst=01:80:c2:00:00:02,dl_type=0x8809 actions=CONTROLLER:65535 [mininet@opendaylight test]\>sudo tcpdump -i s1-eth4 tcpdump: WARNING: s1-eth4: no IPv4 address assigned tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on s1-eth4, link-type EN10MB (Ethernet), capture size 65535 bytes 01:17:27.237038 ARP, Request who-has 10.1.1.2 tell rtr-pet-01.force10networks.com, length 28 01:17:28.238832 ARP, Request who-has 10.1.1.2 tell rtr-pet-01.force10networks.com, length 28 01:17:29.240828 ARP, Request who-has 10.1.1.2 tell rtr-pet-01.force10networks.com, length 28 [mininet@opendaylight test]\>sudo tcpdump -i s1-eth3 tcpdump: WARNING: s1-eth3: no IPv4 address assigned tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on s1-eth3, link-type EN10MB (Ethernet), capture size 65535 bytes 01:17:16.334564 LLDP, length 49: openflow:1 01:17:21.334410 LLDP, length 49: openflow:1 Thanks and Regards R.
