2950 - 3524 passing QnQ tag ?

Hello -

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.

Hi,

You mean you have a trunk between the 2950 and 3524 switch?

Also, I dont think the qinq support is on the 2950;

http://www.cisco.com/en/US/docs/switches/lan/catalyst2950/software/release/12.1_22_ea11x/command/reference/cli2.html

As the command "switchport mode dot1qtunnel" is not listed in the command ref.

Yes - trunk between the two and all is well but not passing the QnQ frames.
