Chapter 21 Double Vlans - NETGEAR GSM7252PS - ProSafe 52 Ports Gigabit Ethernet L2 Managed Stackable Switch Software Administration Manual

ProSafe 7000 Managed Switch Software Administration Manual, Release 8.0.3
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.
Double VLANs:
• Pass customer traffic from one customer domain to another through the metro core
• Select customer ports and a service provider port
In the following example, the two switches have the same configuration.
