I have performed a quick search through the Configuration Guide for the latest IOS release however I do not see any information regarding QinQ being supported for the 2960X. I found a Support thread that did indicate it is not supported for the 2960X model however I did not see any Cisco documentation that indicated that was the case.https://community.cisco.com/t5/switching/cisco-2960x-qinq-supported/td-p/3074587

2016-12-30 · From a Cisco article: Using the 802.1Q tunneling feature, service providers can use a single VLAN to support customers who have multiple VLANs. Customer VLAN IDs are preserved and traffic from different customers is segregated within the service-provider infrastructure even when they appear to be on the same VLAN.https://learningnetwork.cisco.com/thread/103923

2008-1-15 · PPPoE - QinQ Support.

What is the STP state of the ports involved in the forwarding of the traffic between the 2950 during the problem. Provide information for both vlan X and Y so that we can see if there is a difference. QinQ mainly change the data path, there is no MST code related to QinQ. When doing QinQ, you are not running STP with the edge bridges.https://community.cisco.com/t5/switching/mst-and-qinq/td-p/737452

Cisco Switch with Q-in-Q Support Hello Emmanouil, thanks for your nice rating and I see that feature is an advanced feature that combines QinQ with MPLS so it is different from plain QinQhttps://community.cisco.com/t5/switching/cisco-switch-with-q-in-q-support/td-p/2039385

802.1Q tunneling (aka Q-in-Q) is a technique often used by Metro Ethernet providers as a layer 2 VPN for customers. 802.1Q (or dot1q) tunneling is pretty simple…the provider will put a 802.1Q tag on all the frames that it receives from a customer with a unique VLAN tag.https://networklessons.com/switching/802-1q-tunneling-q-q-configuration-example

Cisco Nexus 7000 Series devices can provide only MAC-layer ACL/QoS for tunnel traffic (VLAN IDs and src/dest MAC addresses). You should use MAC address-based frame distribution. Asymmetrical links do not support the Dynamic Trunking Protocol (DTP) because only one port on the link is a trunk.https://www.cisco.com/.../nx-os/interfaces/configuration/guide/if_cli/if_qinq_tunnel.html
