VLAN Tagging and Extra-Tagging
Support for IEEE 802.1Q Extra Tagging, also known as Q-in-Q, allows the FiberLinX-II to more effectively route network
VLAN traffic. Extra tagging simplifies management and configuration efforts for service providers who have customers
using a range of VLAN IDs for different applications. Routing guidelines and other traffic rules can be programmed based
on the extra tag, rather than being programmed for all of the potentially hundreds of individual VLAN IDs. Also, since
a service provider’s customers control their own internal VLAN settings, the extra tag is needed to make sure there is no
overlap of VLAN IDs among customers, and to prevent traffic from different customers from becoming mixed. The extra
tag is removed once the traffic is routed to its correct destination, a process that is transparent to customers.

Media Conversion with Isolated Management
The diagram below illustrates a FiberLinX-II deployment with an IE-MiniFiberLinX-II acting as the CPE at the customer
demarcation point. The devices are configured so that management data is isolated from customer data, and does not
pass through to the customer LAN, while common media conversion functionality is performed without interruption.
