Hi dear All !!!
I have C7609 with ES20.
So, I have created QinQ subinterfaces for solve problems with 4094 Vlans.
But when I typed "sh vlan internal usage", I see internal vlan one per subinterface !!!
And really, I cannot create simple Vlan.
----cut !!! ----
interface Port-channel16.322480
encapsulation dot1Q 322 second-dot1q 480
ip address x.x.x.x y.y.y.y
R#sh vlan internal usage | i Port-channel16.322480
1481 Port-channel16.322480
R#(config)#vlan 1481
VLAN id: 1481 is an internal vlan id - cannot use it to create a VTP VLAN.
----cut !!! ----

Hi Michael !!!
Thank you very much for your answer!
I have read your topic, but I spoke about "QinQ termination" (stacked VLAN processing)
not about selective QinQ. 3750 cannot do it :-(
The QinQ is L2 technology, but "QinQ termination" is L3.

Thank you Mchael !
I began my learning EVC from this blog. It's very nice theme but I have more deep problems.
I'm planing to create more 7K QinQ subinterfaces, but every subinterface create new internal vlan and I have limit 4096 again :-(
