Double VLAN Commands
This section describes the commands you use to configure double VLAN (DVLAN). 
Double VLAN tagging is a way to pass VLAN traffic from one customer domain to 
another through a Metro Core in a simple and cost effective manner. The additional tag 
on the traffic helps differentiate between customers in the MAN while preserving the 
VLAN identification of the individual customers when they enter their own 802.1Q 
domain.
