VLAN Tagging and Extra-Tagging
Support for IEEE 802.1Q Extra Tagging, also known as Q-in-Q, allows the iMcV-Giga-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

Service providers routinely use IEEE 802.1Q Virtual Local Area Network (VLAN) tagging to secure, separate and differentiate
customer traffic. iMcV-Giga-FiberLinX-II enables service providers to support multiple VLAN-based applications.

Application Example
-
Single Remote Solution
A single iMcV-Giga-FiberLinX-II can be used as a single-solution (CPE) application. Install the sole iMcV-Giga-FiberLinX-II
at the customer’s network edge and configure the device as a standalone. Connect the iMcV-Giga-FiberLinX-II to a media
converter at the central office or directly to a fiber switch. Manage the iMcV-Giga-FiberLinX-II from the central office.
• Configure to support VLAN trunking; iMcV-Giga-FiberLinX-II
can trunk 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
