Thanks for your quick response. "tag" is working ,commands you have given I have already used and that works. But I want to work with trunk ports now and if port is trunk with vlan 2 ( we can specify particular vlan also to a trunk port) then untagged packet/other vlan tag packet to trunk port will drop.
so If I am sending same vlan tag packet (vlan 2) then why ping reply is not coming. how trunk with "particular vlan" specified will work in OVS? Am I missing anything? -Sonny On Tue, Mar 20, 2012 at 9:43 PM, Ben Pfaff <[email protected]> wrote: > On Tue, Mar 20, 2012 at 03:09:12PM +0530, sonny sonny wrote: > > Hi All, > > > > I am using OVS 1.2.2 and have one OVS machine with two VMs. > > Following commands I have used - > > > > Create an OVS bridge: > > ovs-vsctl add-br br0 > > > > Add eth0 to the bridge > > ovs-vsctl add-port br0 eth0 > > > > Add VM1 as an “trunk port” on VLAN 2: > > ovs-vsctl add-port br0 vnet0 trunks=2 > > > > Add VM2 on VLAN 2: > > ovs-vsctl add-port br0 vnet1 trunks=2 > > > > now when I am sending tag 2 ping request packet from VM1 to VM2 ( by > > traffic generator) , then ping reply is not coming. > > Please correct me where I am wrong. > > If you add those as trunk ports, then the VMs have to add the tags > themselves.
