Double VLANs
This section describes how to configure the Double VLAN (DVLAN) feature on the switch. A
DVLAN is a way to pass traffic of customers who have multiple VLANs from one customer
domain to another customer domain. Custom VLAN IDs are preserved and a provider service
VLAN ID is added to the traffic so that the traffic can pass the metro core in a simple and cost-
effective manner.
Overview
Double VLANs:
• Pass customer traffic from one customer domain to another through the metro core
• Select customer ports and a service provider port
