[c-nsp] 802.1ad S-TAG - 88a8

[Aaron]

Does anyone know how to make an ME3600 service instance (efp) tag frames
with 802.1ad s-tagging (88a8 ethertype) instead of the typical 802.1q C-tag
(8100) ?

 

I see the way I have this config'd it shows that both tags are 8100
ethertype which I think is technically known as c-tag (8100).  So I guess
you would call this ctag-in-ctag

 

But how would I make the outer tag a TRUE provider tag (aka s-tag, aka 88a8
ethertype)  and leave the inner (bottom customer tag) remain 8100?
