I'm not sure I understand. As of now, there are no fully OF1.1
compliant switches -- the spec has just been released. What did you
compile? The "most complete" 1.1 switch is the openflow python switch
("ofps") that ships with oftest in the oft-1.1 branch, but even it is
missing significant functionality. Is this what you're using?
As for simple description of how to use it, I can point you to the
QinQ test cases in oftest's vlan tests, but the short short
description is that the standard OpenFlow match structure only matches
the outer tag and there are push and pop vlan instructions, so you
would insert flow_mods that express:
if dl_vlan_id = vlan1, then apply action push_vlan(ETHERTYPE_QinQ)
if dl_vlan_id = vlan2, then apply action pop_vlan()
The tests in the vlanact.py oftest file work through this in gory detail.

Rob,
Saeed has compiled the OF1.1 version and wants to experiment with QinQ. Is
there a simple description on how to do this for a simple case?
Cheers,

In OpenFlow version 1.0, the SET_VLAN action implicitly adds a vlan
tag if none exists, but a limitation of 1.0 is that you cannot manage
multiple vlan tags (e.g., QinQ). You can remove the vlan tag with the
STRIP_VLAN action.
Multiple vlan tags are better handled in the recently released
OpenFlow 1.1 specification, that has explicit push and pop vlan
actions.
Both specifications are available at http://www.openflow.org/wp/documents/
Hope that helps,

Hi
I couldn't find any examples on how to use push/pull labels in openflow,
Could any one point me to documentation or example code. in a simple
word how can we add a VLAN tag for a packet entering one port and
leaving through another.
Thanks
Saeed

Rob,
I am using ofp-1.1 branch, the feature that is important for us is
push/pop label and now based on the fact that you said currently it is
missing significant functionality I am confused whether it is part of
completed features or not. If I am right according to features table in
http://www.openflow.org/wk/index.php/OpenFlow_v1.1 it is done (OVS impl
1, OVS impl 2, Python impl and test are in bold). could you please make
it clear for me that do we have push/pop label ready to use or it is not
complete yet.
thanks
Saeed
