General Information

CHAPTER 1: GENERAL INFORMATION

INTRODUCTION

The iMcV-Giga-FiberLinX-III allows network operators to deploy managed
Ethernet services with a full range of remote management, traffic monitoring,
and alarm reporting features. The single wide module offers two fixed
10/100/1000Mbps copper ports and one fiber port in a fixed transceiver in a
variety of wavelengths for SMMM and CWDM. Another model offers an SFP port
that allows copper or fiber SFPs.

iMcV-Giga-FiberLinX-III

The iMcV-Giga-FiberLinX-III supports three main configuration modes:
Standalone, Host/Remote, or as a Host or a Remote. When using Host/Remote,
the Remote modules can be fully managed without an IP address over the fiber
optic segment. The network operator can choose to assign an IP address to the
Host or Standalone module in any mode. Or, if using a local iMediaChassis
managed chassis, all local and remotely connected iMcV-Giga-FiberLinX-III
modules can be managed using the single IP address of the chassis. 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-Giga-FiberLinX-III 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

General Information

 Remote automatic alarms
 Bandwidth limiting
 Link Fault Pass Through (LFPT)
 Loopback testing
 Auto Negotiation
 Selective Advertising
 IEEE-802.3ah OAM support
 Management through UMA
 Console

The iMcV-Giga-FiberLinX-III module is a single-slot, chassis-mounted module.
Compatible chassis include the following:

 iMediaChassis series
 MediaChassis series
 IE-MediaChassis series

PORT INTER FACES

Every iMcV-Giga-FiberLinX-III includes the following ports:

 A 10/100/1000 twisted pair (RJ-45) port (EXT MGMT) for

management

One of the following ports:

 One fixed 1000 Mbps Fiber port, OR
 A SFP port capable of receiving a gigabit or 100Mbps fiber optic SFP

module, or a gigabit twisted pair (RJ-45) SFP module

DATA port:

 A 10/100/1000 twisted pair (RJ-45) port

MANAGEMENT

Although the iMcV-Giga-FiberLinX-III provides a twisted pair port solely for
management (EXT MGMT), the iMcV-Giga-FiberLinX-III 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 available via the console port located at the top of the
module using a Mini-jack adapter.

In addition to defining which ports are used to manage the iMcV-Giga-FiberLinX­III 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 Application Examples for information regarding the Management Domain.

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.

Installation Instructions

CHAPTER 2: INSTALLATION INSTRUCTIONS

Each iMcV-Giga-FiberLinX-III module requires one slot in an iMediaChassis,
MediaChassis or IE-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-Giga-FiberLinX-III module includes on-board SNMP logic. A chassis
other than an iMediaChassis series cannot manage an iMcV-Giga-FiberLinX-III,
so the iMcV-Giga-FiberLinX-III must be managed independently.

When installed in an iMediaChassis, the iMcV-Giga-FiberLinX-III module can be
managed from the chassis by using the Unified Management Agent (UMA). iMcV­Giga-FiberLinX-III modules not managed by UMA must have an IP address
assigned to them after installation before they can be managed. Refer to
Assigning IP Information for more information.

DIP SWITCH SELECTABL E MODE CONFIGURATION

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

 Enable or disable management on each port

(DIP switches 1, 2, and 3)

 Configure the module as a standalone, a host, or a remote

(DIP switches 7 and 8)

DIP SWITCH SETTINGS

Before installing the iMcV-Giga-FiberLinX-III, use the DIP switches to set the
hardware-configurable features. The DIP switches are located on Bay SW1 on
the iMcV-Giga-FiberLinX-III card. Refer to the diagram and table for switch
settings and available features.

HOST /REMOTE AND STAN DALONE UNITS

The iMcV-Giga-FiberLinX-III can be used as a Host, Remote, or Standalone unit.
Refer to the Application Examples section for examples.

When two iMcV-Giga-FiberLinX-III 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-Giga-FiberLinX-III 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-Giga­FiberLinX-III will respond to requests for management information from an
attached Host unit.

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

LOSPD

When LoSPD is set to ON, it will force the SFP mode to run at 100Mbps. If it is
set to OFF, the SFP will run at the highest usable speed determined by the SFP
itself.

MINI -SERIAL PORT

A console port, located on the front faceplate of the module, allows the customer
to use a local RS-232 serial interface for management. A special mini-jack to
DB9-F cable is provided with the product for direct connection to a PC serial port.

5

Configuration

CHAPTER 3: CONFIGURATION

SOFTWARE CONFIGURATI ON

The following sections describe the features that can be configured.

ASSIGNING IP INFORMATION

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

UN I F I ED MANAGEMENT AGENT (UMA)

Centralized management makes practical sense for networks of all sizes,
especially service provider networks that must monitor and upgrade large
quantities of devices. The Unified Management Agent (UMA) allows operators to
manage all devices installed in a B&B iMediaChassis with a single IP address from
a central location. In addition, UMA allows users to centrally manage and
administer firmware upgrades over multiple devices.

AUT O NEGOTIATION, DUPLEX MODE AND SPEE D

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

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

6

Configuration

FOR CING THE SPEED AND DUPLEX MODE

Manually set the twisted-pair ports on the iMcV-Giga-FiberLinX-III for 10 Mbps or
100, or 1000 Mbps operation at Half- or Full-Duplex (i.e., 10 Mbps Full-Duplex,
10 Mbps Half-Duplex, 100 Mbps Full-Duplex, 100 Mbps Half-Duplex, 1000 Mbps
Full-Duplex, 1000 Mbps Half-Duplex). The Optics Port operates at 1000Mbps
Full-Duplex for fixed fiber transceivers, and can support 100Mbps as well as
gigabit fiber SFPs.

SELECTIVE ADVERTISIN G

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 are desired, B&B Electronics recommends using
Selective Advertising, rather than Force Mode, when connecting to devices that
only use Auto Negotiation.

BAND W I DTH CONTROL

The iMcV-Giga-FiberLinX-III includes bi-directional bandwidth control
(configurable via iView2). 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-Giga-FiberLinX-III application. In a Host/Remote iMcV-Giga-FiberLinX-III
application, it can 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).

LINK FAULT PASS THROUGH (LFPT)

Link Fault Pass Through (LFPT) is a diagnostic feature that can be enabled or
disabled. When enabled, it allows the end-user to visually detect that the Link
and the LNK LEDS will extinguish on the front faceplate of the module, when a
fault occurs. LFPT can be enabled through the SNMP software (iView²) or
serial/Telnet.

The iMcV-Giga-FiberLinX-III has three ports: Data, Optics and Ext Management.
LFPT can be enabled between any two ports. For example, if LFPT is configured

as “from” the Optics port “to” the Data port, when a fault occurs on the Optics

port, both LEDs for those ports will extinguish. The end-user can decide which

7

Configuration

port he wants the fault to be reported to, based on which port he wants to be in
control. LFPT allows the fault to be reported down the line, through to the link
partner at the end, such as a switch or a router.

LFPT can be used in addition to setting up SNMP Traps for link up/link down.
LFPT provides a visual way to determine that link is down, and an SNMP Trap
provides a notification of a link down to a designated workstation.

LOO PBACK TESTING

The iMcV-Giga-FiberLinX-III includes Loopback testing functionality. During
loopback testing, management traffic entering the uplink port is still capable of
managing the device. This is selectable form the UNIT screen in a serial/Telnet
session or through iView².

The menu of choices in the CLI includes:

 No loopback, normal traffic mode

 Loopback Enabled

 Loopback, Source/Destination address swap

 Loopback, address swap and clear Multicast bit

 No learning on fiber or Data ports

The menu of choices in iView² includes:

 OFF

 ON

 On- Address Swap

 On-Address swap + Clear MC

8

Configuration

LOOPBACK TESTING ON REMOTE OR STANDALONE

NO LOOPBACK, NORMAL TRAFFIC MODE

The standard mode in which the units function, either as standalone or
Host/Remote.

LOOPBACK ENABLED

Loopback mode without address swap

LOOPBACK, SOURCE/DES TINATION ADDRESS SWAP

A Layer 2 Ethernet switch will discard all received packets with the same MAC
address as sent packets. To avoid this issue the Loopback feature can swap the
source and destination MAC addresses on the looped data. (This selection can
cause a frame with a multicast source address to be created, which violates the
IEEE standard.)

LOOPBACK, ADDRESS SWAP AND CLEAR MULTICAST
BIT

In addition to swapping the source and destination MAC addresses on the looped
data, the Loopback feature can also be set to clear the multicast bit. This allows
the looped data to avoid being blocked by any multicast settings.

LOOPBACK TESTING IN A HOST/REMOTE
CONFIGURATION

The iMcV-Giga-FiberLinX-III is strictly a CPE device; configuration on a Host
would require an iMcV-Giga-FiberLinX-III; select No Learning on OPTICS and
DATA Ports on the Host; on the Remote, choose SRC/DST Address Swap or
Address Swap and Clear Multicast Bit.

9

Configuration

HOST: NO LEARNING ON OPTICS AND DATA PORTS

The Loopback feature can be set to disable address learning on the OPTICS (or
UPLINK) and DATA ports, allowing the loopback to be performed without
interference from MAC address filtering functions. This is a function on the HOST
unit. Set the REMOTE unit for Loopback then set the HOST to disable learning so
Loopback frames pass from the OPTICS port to the DATA port.

REMOTE: SOURCE/DESTINATION ADDRESS SWAP

A Layer 2 Ethernet switch will discard all received packets with the same MAC
address as sent packets. To avoid this issue the Loopback feature can swap the
source and destination MAC addresses on the looped data.

OR

ADDRESS SWAP AND CLEAR MULTICAST BIT

In addition to swapping the source and destination MAC addresses on the looped
data, the Loopback feature can also be set to clear the multicast bit. This allows
the looped data to avoid being blocked by any multicast settings.

CONFIGURATION OPTIONS

The iMcV-Giga-FiberLinX-III includes many features that are configurable via a

for changes to take effect. The Current Values can only be saved and acted on
after the iMcV-Giga-FiberLinX-III has been successfully rebooted.

PASSWORD PROTECTION FOR SERIAL PORT
CONNECTIONS

Password/username is not offered for the serial port by default. This allows the
end user to quickly access the device for some basic configuration capability.
Password protection is provided for the serial configuration process by pressing P
on the main configuration screen. Enter a password, keeping in mind that
passwords are case-sensitive and must not exceed eight characters or include
spaces, and press Enter. This password will be requested whenever logging on.
To remove password protection, select P and, instead of entering a password,
press Enter.

Passwords have the following requirements:

 The password must be between 1 and 8 characters long

 The password consists of a combination of any ASCII characters

except spaces

 Passwords are case sensitive

Passwords are a way to make the management of the devices secure, but
these password lists must be stored and maintained.

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 iView2 (iConfig view), an RS-232 serial session, or a Console session.
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.

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

When DHCP is enabled, the IP address (default 10.10.10.10 or a previously used IP
address, 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 or the previously saved IP and will
reboot.
