[ovs-discuss] Q-in-Q in OF1.3

[Maurice Qureshi]

I just saw following thread on this alias (also attached), is it true for OVS 2.5.0 also? Is it because it is an "optional" action in OF 1.3 spec?

Thanks
Maurice

OVS doesn't support that.

I want to add a flow to push a new tag on top of an existing tag. I see following syntax in different examples:

Ovs-Ofctl Add-Flow <Bridge> <Match-Field> Actions=Push_vlan:<Ethertype>,Set_field:<Value>-\>Vlan_vid,Output:<Port>

Using push_vlan,you can push a new vlan to packets,ethertypeis the ethertype for the tag(only support 0x8100 at the moment.set_field is used to set the value of priority ,the format is like this.


Set_field is for pcp value, where do I specify the 12 bit Vlan value.

A working example will be greatly appreciated.

Thanks
