I have device that I pushing QnQ tags on both ends across a 2950 w/a trunk --- to a 3524.
Is it possible to pass QnQ frames across this trunk or do I need to be running MPLS ?
Not having any luck.
You mean you have a trunk between the 2950 and 3524 switch?
Also, I dont think the qinq support is on the 2950;
As the command "switchport mode dot1qtunnel" is not listed in the command ref.
