We have a site to site 1gb Ethernet link no termination devices for Q-in-Q.
How do I setup Q-in-Q on a pair of these devices so that all of our VLANs can pass through the link. I have found information on how to set it up if the service provider has terminated the link. I have also looked at the standard Cisco model but unfortunately most of the commands do not work on these devices. Some advice or pointers as to best to approach this please.

Cisco 300 series datasheet says it's supported.
Q-in-Q VLAN |
VLANs transparently cross a service provider network while isolating traffic among customers |

CRaju,
Thanks for your response,
The command "switchport trunk encapsulation dot1q" does not work on this switch
