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.
• 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 and Untagged traffic
• 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
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.
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.
iMcV-Giga-FiberLinX-II features an SNMP management agent for monitoring the status and activity on copper and fiber ports at the remote end. Perform
initial setup of the unit and modifications in the field via: iView² SNMP application, Telnet/TFTP, or local serial connection.
• Enable features and change configuration settings from central office
• Remote upgrades via Telnet/TFTP, serial port or iView²
• Monitor both units and the fiber in between
• Receive real-time monitoring and statistics
• Change bandwidth “on-the-fly” up to 1000 Mbps
• Create a secure management domain to isolate management domain broadcasts from TX Data ports on
both units
• User-definable unit/port descriptions and information
Full-Featured iMcV-Giga-FiberLinX-II
From a central location, network operators are able to receive real-time device and traffic statistics on the remote CPE or other devices connected to the
remote management port, allocate bandwidth, turn services on or off, initiate loopback testing, change customer VLAN settings and adjust QoS policies
assigned to different traffic types.
Dedicated Management Port
The EXT MGMT port on the iMcV-Giga-FiberLinX-II provides the ability
to physically isolate the management domain from the data domain,
allowing users to manage edge devices and beyond while protecting the
management domain from unwanted access.
Bandwidth Limiting
With bandwidth throttling Network Operators can control customer
bandwidth offering a range of revenue generating services.
Supports the Unified Management Agent (UMA)
The Unified Management Agent (UMA) allows users to manage all iMcV-
Giga-FiberLinX-II modules installed in an IMC Networks iMediaChassis (and
any connected remote modules) with a single IP address from a central
location, conserving precious IP addresses. Additionally, UMA allows
users to centrally manage and administer firmware upgrades over multiple
devices, saving time.
Troubleshooting Features
FiberAlert and LinkLoss along with LEDs assist in diagnosing potential
problems on fiber optic networks. Additionally, RMON and IFSTAT statistics
are available.
Loopback Testing
Loops back all frames arriving on fiber port (except for the device’s
management traffic). When in Loopback mode, iMcV-Giga-FiberLinX-II
drops the link on the twisted pair port.
Flexibility
Offering unparalleled flexibility, iMcV-Giga-FiberLinX-II supports multiple fiber types including multi-mode and single-mode as well as single-strand fiber,
which can effectively double the capacity of installed fiber. Two Gigabit SFP ports available for WAN and LAN side fiber or copper SFP modules (SERDES
and SGMII); SERDES (1000 Mbps), SGMII (10/100/1000 Mbps).
Choose from one of three different versions:
• One Gigabit Fiber WAN port, and one 10/100/1000 Mbps Twisted pair (RJ-45) LAN port (DATA)*
• One Gigabit SFP WAN port, ideal for either a fiber or copper SFP module, and one 10/100/1000 Mbps Twisted pair (RJ-45) LAN port (DATA)*
• Two Gigabit SFP ports for WAN and LAN side fiber or copper SFP modules
Each version includes a 10/100/1000 twisted pair port (EXT MGMT) for management (can also function as a serial port).
* For the two versions with a DATA port, the iMcV-Giga-FiberLinX-II provides auto-negotiation, automatic crossover detection, full or half duplex and selective
advertising. The DATA port also features Flow Control in Full Duplex Mode (FDX) and Back Pressure Flow Control.
