Anyone use this "switchport vlan mapping" in the 3750 Metro?
I can filter the vlans that I want from the q-in-q tunnel?
As specified never had such a need to recommend this feature to our customers.
SInce you wanted a pointer is this possible I interpreted the feature for you, and how it works.
If you are having any specific problem in testing this in the lab do elaborate so can help you. As this feature is meant to work.
And no the 3750 will not support Double tagged traffic where you want to change the customer VLAN using the grouping you can only change the outer Vlan. And you need to keep the Internal Inner Vlan = External Inner Vlan.
