Flexible QinQ/Service Awareness on 7600 12.2(33)SRB

Hi experts,

I have a scenario whereby the NPE core-facing links are using the 7600-ES20-10G3CXL with MPLS turned on. The UPE facing links are using the WS-X6724-SFP LAN modules. I would like to know in this kind of setup, is the flexible QinQ feature supported, if configured on the WS-X6724 interfaces?

For example:

Module 2 on the 7600 is a WS-X6724-SFP LAN module.

7600-NPE#conf t

Enter configuration commands, one per line. End with CNTL/Z.

7600-NPE(config)#int g2/1

7600-NPE(config-if)#service instance 999 ?

ethernet Configure an Ethernet Instance

7600-NPE(config-if)#service instance 999 ethernet ?

WORD Attach an EVC to the service instance

<cr>

I understand the commands are there, but is this generally a supported feature? Or is the flexible QinQ only supported when a ES20/SIP-400 based card facing UPE is used?

Note: UPE is a 3750ME/ME3400 with 802.1Q trunk towards the 7600 NPE terminating on the WS-X6724.

Appreciate your thoughts on this.

Thanks in advance.
