Hi Ben, If you see my two flow entries made earlier both are having action "NORMAL" but then also if I am making vnet port as access port with vlan 3 then all tag packets are passing through this port and hitting the flow entry in bridge.
cookie=0x0, duration=263.359s, table=0, n_packets=1, n_bytes=60, ip,dl_vlan=3,dl_src=11:22:33:44:55:66 actions=NORMAL cookie=0x0, duration=65.157s, table=0, n_packets=1, n_bytes=60, ip,dl_src=11:22:33:44:55:66 actions=NORMAL Regards, Ed On Thu, Jul 5, 2012 at 3:13 AM, Ben Pfaff <b...@nicira.com> wrote: > The default behavior of the OVS switch is implemented through an action > called "normal".
