About the iMcV-FiberLinX-II

NOTE

Unless noted otherwise, all references to the iMcV-FiberLinX-II in this manual are also
applicable to the iMcV-FiberLinX-II TX/SFP and iMcV-FiberLinX-II SFP/SFP.

Overview

The iMcV-FiberLinX-II allows network operators to deploy managed Ethernet services,
with a full range of remote management, traffic monitoring, and alarm reporting
features. Operators can choose from enhanced versions combining 100 Mbps fiber
to 10/100 Mbps copper media conversion, or an all-copper version. The fiber-to­copper versions are available for a range of fiber connectors (SC, ST, or SFP) and a
variety of wavelengths, supporting higher density CWDM and single-strand fiber
operation.

The iMcV-FiberLinX-II supports two main configuration modes: Standalone or
Host/Remote. When using Host/Remote, the Remote modules can be fully managed
without an IP address, using a secure management channel. In either mode, the
network operator can choose to assign an IP address to the Host or Standalone
module. Or, if using a local iMediaChassis managed chassis, all local and remotely
connected iMcV-FiberLinX-II modules can be managed using a single IP address (the
iMediaChassis IP address). This not only preserves IP addresses and reduces
configuration complexity, but management traffic traveling on the non-IP based
transmission channel is kept isolated from customer traffic, enhancing network
security.

The iMcV-FiberLinX-II offers the following features:

• Securely separates the SNMP management network from the data network

•

IEEE 802.1Q VLAN Tagging
Q-in-Q VLAN Extra-Tagging with EtherType (TPID) selection

•

•

Remote traffic monitoring

•

Remote automatic alarms
Bandwidth limiting

•

FiberAlert (loss return)– Fiber versions only

•

•

FX and TX LinkLoss Link: Fault Pass Through (LFPT)
Loopback testing

•

Auto Negotiation

•

•

Selective Advertising
AutoCross

•

The iMcV-FiberLinX-II module is a single-slot chassis-mounted module.

Compatible chassis include the following:

iMediaChassis series

•

MediaChassis series

•

IE-MediaChassis series

•

Port Interfaces

Every

iMcV-FiberLinX-II

includes the following ports:

• One 10/100 twisted pair (RJ-45) data port

One additional 10/100 twisted pair port (EXT MGMT) for management (can also

•

function as a serial port)

And one of the following uplink ports:

• One 100 Mbps Fiber

•

One additional 10/100 twisted pair (RJ-45)
One SFP port (requires one SFP/155-ED Module)

•

Configure the iMcV-FiberLinX-II by using either the serial craft port connection, or a
SNMP management application such as iView² or a Telnet session.

About Serial Port Configuration

The iMcV-FiberLinX-II includes a serial port on the unused pins of the EXT MGMT
Ethernet port. Connect a local management PC using the included RJ-45 to DB-9
adapter (please refer to the appendix). This RS-232 serial connection provides access
to the iMcV-FiberLinX-II module configuration screens. These configuration screens
are also accessible from a Telnet connection.

DHCP Disable (Static IP Addressing)

DHCP is disabled in the default configuration. Initially, modules are assigned a Static
default IP Address of 10.10.10.10. Changes to the Static IP Address can be added
manually through iConfig, an RS-232 Serial session, or Telnet. The changes will be
initiated following reboot of the module.

DHCP Enable (Dynamic IP Addressing)

If a DHCP server is present on the network and DHCP is enabled, the DHCP client
will initiate a dialogue with the server during the boot up sequence. The server will
then issue an IP address to the management card. Once the new IP address is
received, the SNMP Management Module will reboot so that the new IP address will
take effect. Refer to About Serial Port Configuration for more information about
Enabling/Disabling DHCP.

2

When there is no DHCP server on the network, use iConfig or serial configuration to
manually set the IP addresses.

When DHCP is enabled, the IP address (default 10.10.10.10 or user configured) is
saved. When DHCP is disabled, the saved IP address will be reinstated and the
device will reboot.

DHCP servers give out lease times: devices renew their leases based on the
administrator-specified time. If a device cannot renew its lease, and the lease expires,
the device will be given the IP address 10.10.10.10 and will reboot.

iView2 Management Software

iView² is the IMC Networks management software designed specifically for the IMC
Networks iMcV family of modules. It features a Graphical User Interface (GUI) and
gives network managers the ability to monitor and control the manageable IMC
Networks products.

2

iView

is available in several versions and can also function as a snap-in module for
HP OpenView Network Node Manager. For assistance in selecting the right version
of iView² for a specific operating system, please visit:

http://www.imcnetworks.com/products/iview2.cfm

2

iView

supports the following platforms:

• Windows 98

•

Windows NT

•

Windows 2000
Windows XP

•

•

Windows Vista

In addition, there are Java versions of iView² for other Java capable operating systems
such as Linux.

iConfig Utility

iConfig is a configuration utility in iView² that allows the user to quickly and easily
complete the initial SNMP configuration for IMC Networks’ SNMP-manageable
devices. iConfig can set the IP address, set the Subnet Mask and Default Gateway,
define the Community Strings, and define SNMP Traps. iConfig can also be used to
upload new versions of unit software.

iConfig offers an authorized IP address system and access restriction to MIB groups
supported by the IMC Networks manageable devices. These extra layers of security
are purely optional and do not effect SNMP compatibility in any way.

Default Username/Password

The default user ID and password for both iConfig and Telnet are the following:

User: admin

For information on how to set/change passwords, see

Installation

Each iMcV-FiberLinX-II module requires one slot in an iMediaChassis or
MediaChassis. To install the module in a chassis, remove the blank faceplates
covering the slots where the module is to be installed. Then slide the module into
the chassis card guides until the module is seated securely in the connector. Secure
the module to the chassis by tightening the captive screw.

The iMcV-FiberLinX-II module includes on-board SNMP logic. A chassis other than
an iMediaChassis series cannot manage an iMcV-FiberLinX-II, so the iMcV-FiberLinX­II must be managed independently.

When installed in an iMediaChassis, the iMcV-FiberLinX-II module can be managed
from the chassis by using the Unified Management Agent (UMA). Refer to

http://www.imcnetworks.com/Products/Unified_Management_Agent.cfm

for more
information on using UMA with iConfig, iMediaChassis and iMcV-FiberLinX-II. iMcV­FiberLinX-II modules not managed by UMA must have an IP address assigned to
them after installation before they can be managed. Refer to (

Information

for more information.

I) - Assigning IP

Small Form-Factor Pluggable Ports (SFP)

iMcV-FiberLinX-II modules are available with an optional SFP port. Since the SFP
port speed is fixed at 100Mbps, it is necessary to use a 100 Mbps speed SFP. In
addition, many SFPs, including those from IMC Networks, feature enhanced
diagnostics capabilities with a Digital Diagnostics Monitoring Interface (DDMI).
DDMI statistics provide real-time access to transceiver operating parameters such as
voltage, temperature, laser bias current, and both transmitted and received optical

2

power. DDMI information can be accessed in iView

NOTE

iMcV-FiberLinX-II has been tested with the IMC Networks SFP modules, so it is possible to
install any MSA-compliant SFP module. However, IMC Networks does not guarantee the
functionality of non-IMC Networks SFP modules due to possible non-conformity with MSA
design standards.

Hardware Configuration

Before installing the module in a chassis, there are two features that must be selected
using DIP Switches. These selections include the following:

Enable/Disable management on each port

•
(DIP Switches 1, 2, and 3).

•

Configure the module to be either a standalone, a host, or a remote
(DIP Switches 7 and 8).

DIP Switch Settings

Before installing the iMcV-FiberLinX-II, use the DIP Switches to set the hardware­configurable features. The DIP Switches are located on switch S1 on the iMcV­FiberLinX-II card. Refer to the diagram and table for switch settings and available
features.

Host/Remote and Standalone Units

The iMcV-FiberLinX-II can be used as a Host, Remote, or Standalone unit. Refer to
the

Application Examples

section for examples.

When two iMcV-FiberLinX-II units are used as a pair, configure one as a Host unit
(DIP Switch 8 = On) and the other as a Remote unit (DIP Switch 7 = On). As a host
unit, the iMcV-FiberLinX-II requests management information from the attached
remote unit. It then displays that information, along with its own, when queried by
SNMP. As a Remote unit, the iMcV-FiberLinX-II will respond to requests for
management information from an attached Host unit.

The iMcV-FiberLinX-II default configuration is as a Standalone unit (DIP Switches 7
and 8 = Off).

9

Management

Although the iMcV-FiberLinX-II provides a twisted pair port solely for management
(EXT MGMT), the iMcV-FiberLinX-II can be configured to accept IP-based
management traffic from any of its three ports. Enable management on more than
one port, or disable management on all of the ports, as desired. These switches limit
only IP-based management. Host-to- Remote management is IP-less and is never
blocked from the fiber port. Serial port management of the unit is always available
on the EXT MGMT port regardless of the DIP Switch settings.

In addition to defining which ports are used to manage the iMcV-FiberLinX-II units,
the management DIP Switch settings also define what ports the flow of the Network
Provider’s Management Domain traffic can take through the unit. See

Examples

DIP Switch 1 = On for management on the EXT MGMT port.
DIP Switch 2 = On for management on the DATA port.
DIP Switch 3 = On for management on the OPTICS or UPLINK port.

for information regarding the Management Domain.

Software Configuration

The following sections describe the features that can be configured. Refer to the
iView² online help for iMcV-FiberLinX-II module configuration information.

Assigning IP Information

When the iMcV-FiberLinX-II is installed in an iMediaChassis, use UMA to manage the
iMcV-FiberLinX-II without an IP address (refer to the iView² online help for more
information on UMA). When the iMcV-FiberLinX-II is not installed in an
iMediaChassis, SNMP-management is not accessible until the iMcV-FiberLinX-II IP
information (e.g., IP address, subnet mask, etc.) is configured (using iConfig, a serial
port craft connection, or DHCP). After assigning iMcV-FiberLinX-II an IP address, use
iView² or another SNMP-compatible Network Management System (NMS) to
remotely configure, monitor and manage the iMcV-FiberLinX-II.

Auto Negotiation, Duplex Mode, and Speed

The DATA and EXT MGMT ports on the iMcV-FiberLinX-II module Auto Negotiate for
speed and duplex mode. This module also provides the option of selectively
advertising or forcing the speed and duplex mode.

Auto Negotiation

The iMcV-FiberLinX-II ships from the factory with Auto Negotiation enabled on the
twisted-pair ports. In this mode, the ports negotiate for speed and duplex.

Forcing the Speed and Duplex Mode

Manually set the twisted-pair ports on the iMcV-FiberLinX-II for 10 Mbps or 100
Mbps operation at Half- or Full-Duplex (i.e., 10 Mbps Full-Duplex, 10 Mbps Half­Duplex, 100 Mbps Full-Duplex, etc.). The Optics Port operates at 100Mbps Full­Duplex.

Selective Advertising

Selective Advertising, when used in combination with Auto Negotiation, advertises
only the configured speed and duplex mode for the twisted pair port. If a specific
speed and/or duplex mode are desired, IMC Networks recommends using Selective
Advertising, rather than Force Mode, when connecting to devices that only use Auto
Negotiation.

Bandwidth Control

The iMcV-FiberLinX-II includes bi-directional bandwidth control in 32 Kbps
increments (configurable via iView

2

). This allows the bandwidth limit to be set
independently from the DATA Port to the OPTICS (or UPLINK) Port and vice versa in
a single iMcV-FiberLinX-II application. In a dual iMcV-FiberLinX-II application, it can

11

be set from the Host unit to the Remote unit and vice versa (i.e., the bandwidth on
the DATA ports on both the Host and Remote modules can be limited
independently).

NOTE

Management packets do not have priority over data packets.

Configuration File Save/Restore Function

Requirements

FiberLinX-II family series:

Minimum firmware version required: A4
iMcV-FiberLinX-II: A1 or higher,

Required iView² version: 1.8.4 or higher

The Configuration File Save/Restore Function allows a user the ability to backup all
the configuration settings of a unit. With this backup, a user can restore settings to a
unit if necessary or use this backup to apply the same settings to a different unit.

All configurable managed objects are saved in a configuration file that is stored in the
unit’s Large File Area. This includes all configurable settings such as VLAN
configurations, IP Address configuration and SNMP agent settings. The configuration
file can be transferred from the unit to a PC and saved to disk through the iConfig
protocol. The configuration file can be transferred from a PC to a unit of the same
type through iConfig or TFTP into the unit’s Large File Area. After the transfer is
complete, the unit copies the configuration to flash and reboots.

The configuration file’s contents is device-type specific and can be identified by
iConfig as a configuration file as well as to what type of device it is applicable to.

How to Save a Configuration File

To save a configuration file, use the iConfig tool. Log into the unit through iConfig,
navigate to the iConfig Administration tab, select the “S

ave Configuration

” button,
wherein a prompt requires a file name, as well as any user notes. From this point the
file will be transferred to the PC’s disk through the iConfig network protocol.

12

Once the file is saved to disk it can be restored to the device or sent to another like
device through iConfig or TFTP.

For iConfig

The user will log into a unit, select the Administration tab, select the

Upload Configuration

button, be prompted to locate a
configuration file on the PC’s disk. From this point the file transfer
will take place from the PC to the unit. After a successful transfer,
the user will be prompted to Reboot to make the new configuration
active.

For TFTP

The user will log into the unit either through a serial port session or
through Telnet. They will navigate to the download command page,
enter the TFTP server’s IP address and enter the configuration file

Enter

name, then press

to start the download process. Once the
download is successful, the user will be prompted to apply the
settings. The device must be rebooted after applying the settings to
make them active.

By default, the IP Address configuration currently on the device is kept intact and not
overwritten by the new configuration file.

Configuration File Basics

FX/TX LinkLoss and FiberAlert

key

During normal operation, link integrity pulses are transmitted by all point-to-point
Ethernet devices. When an iMcV-FiberLinX-II receives valid link pulses, it knows that
the device to which it is connected is up, and that the copper or fiber cable coming
from that device is intact. The appropriate LNK (link) LED is lit to indicate this. For
troubleshooting information utilizing the LinkLoss and FiberAlert features of the iMcV­FiberLinX-II modules, refer to

FiberAlert and LinkLoss features cause data interruptions designed to alert remote sites of line
failures. These data interruptions can be misinterpreted as module failures when these features
are enabled. Enable these features only when the resulting data interruptions and causes are
well understood.

Troubleshooting

** WARNING **

at the end of this manual.

FX LinkLoss

FX LinkLoss is a link integrity monitoring feature that forwards fiber link faults to the
RJ-45 Data port to indicate that a fiber link fault has occurred.

TX LinkLoss

TX LinkLoss is a link integrity monitoring feature that forwards an RJ-45 link fault to
the fiber connected device to indicate that a link fault has occurred.

FiberAlert

FiberAlert minimizes the problems associated with the loss of one strand of fiber.
Normally when a single strand of fiber is lost, the transmitting side of the connection
