Stacking In QinQ mixed vlan mode:
• Stacking is only supported on C-VLANs. The device does not advertise
itself (using the stack discovery protocol) in the S-VLAN space.
In QinQ svlan mode:
• Stacking discovery protocol frames will not be sent out of
customer-network ports; similarly, any stacking discovery protocol
frames received on customer-network ports will be dropped.
UDLD In QinQ mixed vlan or svlan modes:
• UDLD frames received on udld-disabled customer network ports will
be dropped. However, if the customer-network port is udld-enabled, it
can peer with a customer device.
• UDLD frames received on udld-disabled provider network ports will be
reforwarded out of other udld-disabled provider network ports on the
same VLAN.
• UDLD reforwarding in the C-VLAN space (QinQ disabled or mixed vlan
mode) will remain unaltered.

forward
In QinQ svlan mode:
• udp-bcast-forward is NOT supported on provider core devices.
unknown-vlans In QinQ mixed vlan mode:
