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..)

Hi
I am search a solution for this project:
Cisco 7301 connected to a Cisco 3750 "A" by a Fiber Gig port. Port is in
trunk
C7301<==> C3750 port gig 0/24
The cisco 3750 "A" is connecter in trunk to a carrier by the Gig 0/23.
The carrier supply 4 ports:
1 Central Port connected to C3750 "A"
1 Port connected to C3750 "B"
1 Port connected to C3750 "C"
1 Port connected to C3750 "D"
And on each, he supply one vlan
Vlan 100: From C3750"A" to Cisco 3750 "B"
Vlan 101: From C3750"A" to Cisco 3750 "C"
Vlan 102: From C3750"A" to Cisco 3750 "D"
I want use QinQ for:
Cisco 7301 use vlan 500 to 600 for going on 3750 "B"
Cisco 7301 use vlan 700 to 800 for going on 3750 "C"
Cisco 7301 use vlan 900 to 1000 for going on 3750 "D"
Sample:
C7301 ge0/1.500 => trunk => C3750 "A"<== Dot1q Tunnel into Vlan 100
==> C3750 "B" => Trunk => C2821 ge1/1.500
C7301 ge0/1.750 => trunk => C3750 "A"<== Dot1q Tunnel into Vlan 101
==> C3750 "C" => Trunk => C1841 ge1/1.750
C7301 ge0/1.950 => trunk => C3750 "A"<== Dot1q Tunnel into Vlan 102
==> C3750 "D" => Trunk => C2811 ge1/1.950
It's possible ?
Thanks
Olivier
