Sorry it took me a bit to respond but that command output is just too long to be of any use when doing it in the normal production environment so I set up a fresh XCP server with a test VM on it, configured it for SLB bonding and put it in an isolated VLAN. Some background information: 192.168.0.124: Laptop I used to connect to the XCP server and the VM 192.168.0.157: Test VM 192.168.0.171: XCP server Here is the complete output of the command. I ran it multiple times, but the output didn't change (if you disregard counters). --- cut --- priority(6),in_port(0),eth(src=00:1a:64:8f:a5:9e,dst=00:16:41:55:fa:75),eth_type(0x0800),ipv4(src=192.168.0.171,dst=192.168.0.124,proto=6,tos=0x10,ttl=64,frag=no),tcp(src=22,dst=44899), packets:4, bytes:504, used:0.020s, actions:1 in_port(4),eth(src=b2:76:b4:94:5d:e1,dst=ff:ff:ff:ff:ff:ff),eth_type(0x0800),ipv4(src=192.168.0.157,dst=192.168.0.255,proto=1,tos=0,ttl=64,frag=no),icmp(type=8,code=0), packets:104, bytes:10192, used:0.570s, actions:2,0 in_port(1),eth(src=b2:76:b4:94:5d:e1,dst=ff:ff:ff:ff:ff:ff),eth_type(0x0800),ipv4(src=192.168.0.157,dst=192.168.0.255,proto=1,tos=0,ttl=64,frag=no),icmp(type=8,code=0), packets:104, bytes:10192, used:0.570s, actions:drop in_port(1),eth(src=00:16:41:55:fa:75,dst=00:1a:64:8f:a5:9e),eth_type(0x0800),ipv4(src=192.168.0.124,dst=192.168.0.171,proto=6,tos=0,ttl=64,frag=no),tcp(src=44899,dst=22), packets:7, bytes:606, used:0.020s, actions:0 --- cut --- As you see, I was connected via SSH to the XCP server and the Test VM. I used the Test VM to send broadcast ping packets to 192.168.0.255. I used tcpdump on the XCP server listening on the two interfaces forming the bond and filtering for broadcast traffic and I saw the ICMP ECHO_REQUEST packets going out on both interfaces as on the production XCP servers. > Can you also post the logs? Well, there aren't much log files - at least not much I was able to find. --- cut --- # ls -l /var/log/openvswitch total 4 -rw-r--r-- 1 root root 0 Jan 25 13:51 ovsdb-server.log -rw-r--r-- 1 root root 0 Jan 25 13:51 ovs-vswitchd.log -rw-r--r-- 1 root root 160 Jan 25 13:52 ovs-xapi-sync.log # cat /var/log/openvswitch/ovs-xapi-sync.log Jan 25 13:52:19|1|reconnect|INFO|unix:/var/run/openvswitch/db.sock: connecting...
