When you use the
vlan-type dot1q vid second-dot1q
command to configure ambiguous
QinQ termination multiple times, one of the following conditions occurs:
{
If the most recently specified Layer 1 ID is the same as the current Layer 1 ID, the specified
Layer 2 IDs in both configurations take effect.
{
If the most recently specified Layer 1 ID is different from the current Layer 1 ID, you must
first delete the old configuration.
To configure ambiguous QinQ termination:

Configure ambiguous
QinQ termination by
specifying the outermost
two layers of VLAN IDs.
