QinQ on 4500X

I configured selective QinQ on a Cisco 4500X interface.  The remote vendor's switch is an MRV 9244.  After troubleshooting for about 2 hours, we were still unable to pass traffic over the C-tagged VLANs.  I can see the remote MAC addresses on the vendor's S-tag VLAN.  The vendor is using "standard" QinQ and tried selective QinQ, but to no avail.  Any help would be appreciated.

 

My config:

interface TenGigabitEthernet1/1/7

switchport trunk allowed vlan 2693

switchport mode trunk

switchport vlan mapping 701 dot1q-tunnel 2693

switchport vlan mapping 702 dot1q-tunnel 2693

mtu 1504

end
