VLAN Tagging and Extra-Tagging
Support for IEEE 802.1Q Extra Tagging, also known as Q-in-Q, allows the iMcV-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.
• IEEE 802.1Q VLAN compatible
• Valid VLAN IDs are 1 to 4,094
• Port-based VLAN tagging
• Transparency Mode passes all data and respects the VLAN tag or lack thereof, i.e. allows a mixture of VLAN Tagged
• Valid VLAN IDs are 1 to 4,094
• Port-based VLAN tagging
• Transparency Mode passes all data and respects the VLAN tag or lack thereof, i.e. allows a mixture of VLAN Tagged
and Untagged traffic
• Configure to support VLAN trunking; FiberLinX-II can filter up to 32 VLAN IDs for data, plus an additional ID for SNMP
(Transparency Mode disabled)
• IEEE 802.1p provides a 2-tier queue for differential prioritization of inbound and outbound traffic. For example, VoIP
applications can be assigned a higher priority than data traffic
Service providers routinely use IEEE 802.1Q Virtual Local Area Network (VLAN) tagging to secure, separate and differentiate
customer traffic. The iMcV-FiberLinX-II enables service providers to support multiple VLAN-based applications.

Media Conversion with Isolated Management
The diagram below illustrates an iMcV-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.
