Hi, Satoshi
Packet destination is not changed and I can see it in the wireshark.
The packet in the first node is matched with this rule:
flow entry:
cookie=0x0, duration=10.280s, table=0, n_packets=0, n_bytes=0,
vlan_tci=0x1000/0x1000,dl_dst=10:00:00:00:00:02 actions=group:6
group entry:
group_id=6,type=ff,bucket=watch_port:1,actions=output:1,
bucket=watch_port:2,actions=output:2,set_field:4162->vlan_vid
but in the next node it is dropped.
Thanks
