[c-nsp] QinQ Cisco 3750 ?

[Ivan]

Hi Oliver,

I think what you are wanting to do is called "selective QinQ".  For this 
you are looking at hardware such as ME3400 
(http://www.cisco.com/en/US/docs/switches/metro/me3400e/software/release/12.2_50_se/configuration/guide/swtunnel.html#wp1059629)

For port A you would end up with something like this on a ME3400

Switch(config)# interface gigabiethernet0/1
Switch(config-if)# switchport vlan mapping 500-600 dot1q-tunnel 100
Switch(config-if)# switchport vlan mapping 700-800 dot1q-tunnel 101
Switch(config-if)# switchport vlan mapping 900-1000 dot1q-tunnel 102
Switch(config-if)# switchport vlan mapping drop default
Switch(config-if)# exit

You can also do similar on the ES+ lincards and maybe even the 3750ME 
(probably limited to the ES ports..)
