Hi Ben,

Sorry for the poor English. I try to describe my problem clearly. Currently,
we could configure the VLAN function of OVS successfully and work well when
our two servers (installed OVS) directly connected via a network cable. But
when we deploy these two servers to our physical switch, we meet a problem
that the VMs on these servers (have the same VLAN ID) could not ping
successfully. Our physical switch is Cisco 3750 and we have set the ports,
connected two servers, to be trunking ports. Would you have any experiences
for this situation?

Thanks again
