About the Giga-AccessEtherLinX-II

The Giga-AccessEtherLinX-II Series enables service providers to offer differentiated
data networking or

VPN services to multi-tenant building and business customers.
Residing at the customer premises or at the service provider POP, Giga­AccessEtherLinX-II provides

a VLAN-based Layer 2 entry point to the MAN fiber
network, trunking, differentiating and grooming customer traffic. Featuring remote
SNMP management,
prioritization and

port bandwidth control, QinQ support, QoS, traffic

multicast pruning (using IGMP v1, v2), it is an ideal solution for

delivering Ethernet-based services to customers quickly and cost-effectively.

Giga-AccessEtherLinX-II offers configuration access via Telnet, console, secure IP-Less,
and SNMP management channels. Software upgrades can be initiated via any one of
these access methods.

The Giga-AccessEtherLinX-II includes
10/100/1000 twisted pair) and

four 10/100/1000 Mbps twisted pair Ethernet

one Uplink port (either 1000Base-FX fiber or

Downlink Ports for connecting users/LANs, and supports jumbo frame sizes of up to
9600 bytes.

The Giga-AccessEtherLinX-II offers various wavelengths for SM and MM fiber at
gigabit speed; single-strand and SFP versions are also available. As a standalone unit,
it is available in an internal AC or DC version.

Installing the Giga-AccessEtherLinX-II

The Giga-AccessEtherLinX-II comes ready to install; there is no hardware
configuration required. All features, such as management access, qualified VLAN
tags, Link Fault Pass-Through and Auto Negotiation are software configurable.

Place the Giga-AccessEtherLinX-II on a flat surface, prior to installation. Attach the
cables between the Giga-AccessEtherLinX-II and each device that will be
interconnected and then plug the unit into a reliable power source.

INSTALLATION TIP

Single-strand fiber products use optics that transmit and receive on two different
wavelengths. Single-strand fiber products must be deployed in pairs, connecting two
compatible single-strand fiber products. Connect the 852-10310 (1310 xmt and 1550 rcv),
for example, to a product with 1550 xmt and 1310 rcv, e.g., 852-10311 (1550 xmt and
1310 rcv.) The two connected products must also have the same speed and distance
capabilities (i.e. both are single-mode [20 km] or both are single/PLUS [40 km]).

Features

Two Layer Qualified Q-in-Q Support

Each drop port can be assigned two different VLAN tags to incoming frames based on
the frames PRI or DSCP priority value and IP or Non-IP Frames types. In this way,
incoming traffic to the network can be groomed into different VLAN tributaries before
entering the network.

AutoCross Feature for Twisted Pair Connection

All twisted pair ports on the Giga-AccessEtherLinX-II include AutoCross, a feature
which automatically selects between a Crossover workstation or Pass-Through
connection depending on the connected device.

Software Configurable Features

The Link Fault Pass-Through, Selective Advertising, as well as Qualified VLAN tags
and Bandwidth Control features are all configurable via the SNMP IP-Less
management, DB-9 console configuration or Telnet session.

2

IP-Less Management in HOST/REMOTE configurations

A proprietary, secure management communication channel is supported whenever
the Giga-AccessEtherLinX-II unit is connected directly to an iMcV-GigaFiberLinX-II
unit over the Fiber Uplink. This secure communication channel does not require any
pre-configuration or IP address assignment. It automatically establishes an integrated
Host-Remote management connection between these units, allowing them to be
managed as a single unit, as long as the iMcV-Giga-FiberLinX-II unit is set to a unit via
the DIP Switch setting.

Priority Queuing and Flow Control

The unit supports two different priority queuing schemes. In all modes that do not
allow frame qualification, Priority Queuing is set globally for all ports as a Unit
Control Setting. For modes supporting Qualification, high priority is set individually
per port by the Qualification setting. Frames qualified as high priority will be given
preference over low priority frames to egress the unit.

When internal congestion occurs and the unit is low on internal buffer space, only
high priority frames will be allowed to enter the unit. If Flow Control is enabled,
PAUSE frames will be sent to all ports causing the congestion. If PAUSE frames are
received on a port, that port will not transmit frames until the PAUSE condition has
expired.

Auto Negotiation, Duplex Mode and Speed

The twisted pair ports on the Giga-AccessEtherLinX-II Auto Negotiate for speed and
duplex mode. This device can also selectively advertise or force the speed and
duplex mode. If the device has a fiber Uplink port, it always operates at 1000 Mbps
full-duplex and supports Auto Negotiation on the fiber segment.

Forcing the Speed and Duplex Mode

The twisted pair Downlink Ports on the Giga-AccessEtherLinX-II can also be manually
set for 10, 100, or 1000 Mbps operation and for half- or full-duplex mode (note:
1000 Mbps only supported in full duplex).

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 is desired, use Selective Advertising, rather
than a Force Mode, when connecting to devices that ONLY auto negotiate.

Bandwidth Control

The Giga-AccessEtherLinX-II includes bandwidth control functionality. A maximum
bandwidth can be set independently on each port for both receive and transmit
directions.

About iView² Unit Management

iView² is a network management application for IMC Networks’ intelligent
networking devices. It features a GUI, which provides network managers the ability
to monitor and control IMC Networks’ products. The application is available in
several versions including Web-Server version 3.0 and can also function as a snap-in
module for HP OpenView Network Node Manager.

iView² supports the following platforms:

• Windows NT

• Windows 2000

• Windows XP

• Windows 7

• Windows Vista

Utility iConfig

iConfig is an in-band utility created by IMC Networks, used for SNMP configuration
for IMC Networks’ SNMP-manageable devices.

The iConfig feature allows the following to be performed:

• Set an IP address, subnet mask and default gateway

• Define community strings and SNMP traps

iConfig also includes an authorized IP address system and restricted access to MIB
groups which are supported by IMC Networks’ manageable devices. These extra
layers of security do not affect SNMP compatibility. iConfig can upload new versions
of the system software and new MIB information. It also includes diagnostic
capabilities for faster resolution of technical support issues.

Default Username/Password

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

User: admin / Password:admin

4

SNMP, Telnet and Console Management

SNMP, Telnet, and iConfig management channels are always supported through the
Giga-AccessEtherLinX-II Uplink Port. This provides a higher level of security so end
users cannot access management, alter settings, etc. Management through other
ports can be supported through unit configuration.

In order for the Giga-AccessEtherLinX-II to support SNMP management, the unit must
be assigned IP configuration information (e.g., IP address, subnet mask, etc.) There
are five ways to do so:

• Using iConfig (IP-Less on same Ethernet Domain)

• Host-Remote IP-Less from an iMcV-GigaFiberLinX-II

• Using the console DB9 port located on the back of the unit

• Using DHCP (Dynamic Host Control Protocol); DHCP must be enabled

through the console configuration or Telnet

• Telnet (Default IP=10.10.10.10; subnet mask=255.0.0.0)

In addition to assigning an IP Address and subnet mask, the end user can create
community strings, assign access rights, and configure traps for total remote
management.

About Console Port Configuration

Use the console DB-9 port on the back of the unit to access the internal Command
Line Interface (CLI).

To connect the Giga-AccessEtherLinX-II to a terminal/computer, use a straight­through (pin-to-pin) cable. (If the computer/terminal has a COM port using a
connection not compatible with a DB-9 connector, use the pin connection chart
shown below for reference in making a cable.) Make sure the cable length is less
than 50 feet (15.24m). Plug one end of the cable into the DB-9 connector and the
other into the appropriate computer/terminal port. Set the computer/terminal for

About DHCP

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 Console 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 the

About Console Port Configuration

for more information
about Enabling/Disabling DHCP. When there is no DHCP server on the network, use
iConfig or console 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.

Enter

to be taken to the Download a file screen. This screen displays the IP Address of the
TFTP server and the name of the file to be downloaded. The TFTP server should be
open. Make sure the IP Address and the name of the file are correct.

Configuring VLANs

The Giga-AccessEtherLinX-II is VLAN compatible, with the ability to accept traffic
containing 802.1q VLAN tags on the Uplink port and direct that traffic to the
Downlink Ports where the tag is removed on egress. For even greater flexibility, each
port can be individually configured as an Uplink TRUNK port or as a Downlink
DROP port. Every downlink port can qualify the incoming Ethernet frame and assign
one of two different VLAN tags depending on the priority of the incoming frame.

Qualified VLAN Settings

Incoming frames can be qualified based on the PRI value found in its VLAN tag or on
the DiffServ value found in the IP header of the frame.

Pre Configured Modes

To help alleviate the complexity associated with this, the Giga-AccessEtherLinX unit
has provided eight different modes of operation. Each mode is designed to support a
common customer application to help simplify the configuration process. The
following is a short summary of each mode.

Mode 1

Forwards only untagged frames. Management only accepted from the

Uplink Port.

Mode 2

Forwards both tagged and untagged frames with management only
accepted from Uplink Port. Management domain can flow to Downlink
Ports and can be assigned a VLAN. This is the default mode and
functions as a normal MAC layer switch.

Mode 3

Mode 4

Forwards both tagged and untagged frames with management only
accepted from Uplink Port. Management domain is blocked from
Downlink Ports and can be assigned a VLAN.

Allows fixed port-based forwarding. The user-configured virtual

11

connection between ports includes management. Management can be
assigned a VLAN.

Mode 5

Mode 6

Mode 7

Mode 8

Only accepts untagged traffic at the Downlink Ports. All Uplink traffic is
tagged. Each Downlink Port adds a Qualified or Not Qualified VLAN tag
to all ingress traffic. Management only accepted from Uplink Port and
can be assigned a VLAN.

Accepts both tagged and untagged traffic at the Downlink Ports. All
Uplink traffic is tagged. Each Downlink Port adds a Qualified or Not
Qualified VLAN tag to all ingress traffic. Management only accepted
from Uplink Port and can be assigned a VLAN.

Allows each port to be defined as a Drop or a Trunk port. Each Drop
port assigns a Qualified or Not Qualified VLAN-tag to all ingress traffic.
Assigned VLAN tags are added to the packet when they exit a Trunk port.
Management is accepted on any Trunk port and can be assigned a VLAN.

Allows up to 64 VLAN IDs to be defined. Each port can be a tagged or
no-tag member of a defined VLAN. A tag member ports will allow these
tagged frames to enter/exit the port. No-tag members’ ports will add this
tag to assigned frames at egress. NOTE, only one No-tag VLAN can be
assigned to a given port but any or all defined tags can be assigned as tags
for a given port.

To configure VLAN IDs, press the

Spacebar

when in the Command List section of the

Main Configuration screen (console configuration). VLAN is an available option.

vlan

Type

and press

Enter

for VLAN Configuration.

VLAN Mode Screen

When accessing

vlan

in the Main Task Screen, the current VLAN mode is displayed.
The first screen for each mode provides an overview and features of that mode, as
well as instructions on how to proceed through the mode or return to the previous
menu.

12

Mode 1—Untagged Frames Only

In this mode, the unit functions as a managed MAC layer switch with management
only accepted on the fiber Uplink and no VLAN support.

Mode 2—Mixed Tagged and Untagged Frames (Default)

When Management can be VLAN tagged, the following screen is given for
configuration.

13

Mode 3— Mixed Tagged and Untagged, Block MGMT Domain

14

Mode 4— Port Based Forwarding

Port Based Forwarding selection is done on the following screen:

Mode 5—Port Based VLANs

Only untagged frames are delivered to the Downlinks.

15

Each port can assign two different VLANs based on the ingress frame classification.

For untagged frames, the DiffServ priority value of the IP frame can be used for
classification. This screen allows the user to select any of the 64 values. In addition
the user must identify whether non-IP frames are also classified.

16

Mode 6—Port Based Extra Tag

In this mode both untagged and tagged frames can enter the drop ports.

Two VLANs per port can be assigned based on ingress frames

17

classification.

In this mode both tagged and untagged frames can enter the drop port. Tagged
frames can now be classified based on the PRI value within the incoming VLAN tag.
Any PRI value can be used to classify the frame.

18

Mode 7— Port Based Extra Tag, Infrastructure

19

Mode 7 allows the user to define whether a port is a Trunk (passes everything,
including management), or a Drop (can add/remove VLAN tags). Unit management
is also enabled through any Trunk port.

Once a port is defined as a Drop Port, additional screens are provided to assign
VLAN values based on the classification of the incoming frame.

20

Mode 7 also allows the user to define whether PRI or DiffServ values are used to
classify incoming frames and whether non-IP frames are classified. Classification is
done on a port-by-port basis.

21

Mode 8—VLAN Assigned

Mode 8 allows up to 64 VLAN IDs to be defined. Each port can be a tags or No-tags
member of a defined VLAN. A tags member port will allow these tagged frames to
enter/exit the port. A No-tags member port will add this frame at egress. Only one
No-tag VLAN can be assigned to a given port, but any or all defined tags can be
assigned as tags for a given port.

Mode 8 allows total flexibility by combining both Trunk and Drop port capabilities
allowing both VLAN filtering and tagging on the same unit.

22

Only one No-tags can be assigned to a port; this indicates that all frames entering the
port that do not match the assigned members VLAN-ID list are given this indicated
tag. All frames leaving the port with this tag will have it removed. Assigned tag
frames (tags) will pass through this port without changes.

Unit Control Settings

Global unit settings are configured on this screen and apply to all ports.

Unit Loopback loops all frames entering the fiber Uplink Port back to the fiber port.

Unit Max Frame Size can be set as high as 12.2K Bytes. However, the unit can not
sustain a continuous stream of this jumbo frame without some frames loss. Sustained
MAX frames size with no frame loss is limited to 8.2K bytes.

802.1p Base Priority is a value from 0 to 7 that is used to divide incoming frames into
High and Low priority groups. A Base Value of 4 indicates that any VLAN tag with

4 will be given High Priority status inside the unit, is applicable to Modes

PRI>
2,3,and 4 only.

The unit can be configured to Block Bridge, GARP, and All Bridge protocol frames.

23

Bandwidth Limiting

Bandwidth Limiting can be set per port in both transmit and receive directions. The
limiting function provides a Leaky Bucket traffic shaping function when placed on the
TX side of a port. When the transmit limit is reached on a port, it will stop
transmitting until the bucket level falls below the set level. When placed on the RX
side it functions more like a hard Bandwidth limiter. When the Bucket level is
reached, the port will stop receiving frames and will issue PAUSE frames back to the
port until this bucket level clears.

Bandwidth Limiting is entered as any value from 0 to the MAX bandwidth of the port.

24

Port Configuration

The Giga-AccessEtherLinX-II Downlink Ports can be configured via console
configuration. Type

and press

Enter

to be taken to the Port Configuration

ports

screen. From this screen, users can enable/disable ports and set Auto Negotiation
and Flow Control functions, etc. (This can also be performed via iView².)

When a port is disabled, it will no longer show LINK or send any traffic to the port.

Flow Control will cause a port to send PAUSE whenever the ports internal buffer
space is low. This can be affected by both Bandwidth limit setting for the port and
traffic congestion on the port.

Forced Flow Control should only be used when the connected end device does not
support Auto Negotiation.

25

System Descriptions

This screen allows the user to define unit and port names that are incorporated by the
unit into all SNMP traps. These are extremely useful in troubleshooting the system.

Firmware and Unit Version Information

To help maintain Software revision control, these reference numbers are always
updated whenever unit software is downloaded to the equipment.

26

Using Management

iView² is a network management application for IMC Networks intelligent
networking devices. It features a GUI and gives network managers the ability
to monitor and control products from a variety of platforms.

Using iView² with HP OpenView

During the installation, the iView² application will ask if HP OpenView is
installed on the management PC. Click Yes to integrate the appropriate files.
Once in OpenView, highlight the media converter icon and select the media
converter; OpenView will then launch iView².

Other NMS Applications

If using an application other than iView² for management, integrate the
SNMP vendor MIBs, which can be found in the MIB subdirectory of iView²
installed on the chosen hard drive of a workstation.

Refer to the application's documentation for information on how MIB files
are integrated.

Update Manager

iView² offers the option of scheduling an update search for IMC Networks devices
listed in the Network outline. Within iView², select
navigation toolbar. Select

Update Manager Options

Tools/SNMP Options

, and a dialog box will be

from the

displayed, in which you can select when to run the update search. This option
enables the end user to determine if they have the latest firmware, and download the
latest if they do not. It does not automatically run the download, so the end user can
review the release notes included with the binary file, and decide whether to
download it or not.

UMA (Unified Management Agent)

The UMA allows operators to manage all IMC Networks modules with on-board logic
(iMcV-GigaFiberLinX-II series) installed in an IMC Networks iMediaChassis, with a
single IP address from a central location. Centralized management makes practical
sense for networks of all sizes, especially service provider networks that must monitor
and upgrade large quantities of devices. In addition, UMA allows users to centrally
manage and administer firmware upgrades over multiple devices.

For example, the user can install ten iMcV-Giga-FiberLinX-II devices in a 20 slot
iMediaChassis at the Central Office (CO) and connect each to a remote Giga­AccessEtherLinX-II unit installed at the customer’s premises equipment (CPE). UMA
allows users to manage all 20 devices (including the chassis at the CO) via the single

27

IP address assigned to the chassis management card. Users may still assign IP
addresses to each iMcV-Giga-FiberLinX-II and Giga-AccessEtherLinX-II, and manage
them independently over the network being transported but this may not provide the
same level of security as the UMA system.

With the Unified Management Agent

When an SNMP request for an iMcV-Giga-FiberLinX-II comes in, the SNMP
Management Module in the iMediaChassis passes the request to the SNMP agent in
the specific module. The SNMP agent in the iMcV-Giga-FiberLinX-II provides the
relevant management information for both the iMcV-Giga-FiberLinX and the remote
Giga-AccessEtherLinX-II unit using a secure IP-Less messaging channel to the remote
unit.

IP-Less Management

The Giga-AccessEtherLinX-II supports the IMC Networks secure management system
that allows the unit to function as an integrated remote unit when attached to a Giga­AccessEtherLinX-II Host unit over a fiber link segment. In this mode the two units are
managed as one integrated pair without the need of an assigned IP address at the
remote unit.

File Management for Upgrading

The following screen, located in the iConfig utility of iView², shows the File
Management functionality of the Unified Management Agent. Operators can easily
upload and store new firmware versions for upgrading multiple devices with on-board
logic installed in, or connected to, an iMediaChassis.

28

Using Telnet

Assign the Giga-AccessEtherLinX-II an IP Address or use the default IP Address

10.10.10.10, subnet mask 255.0.0.0 before using a Telnet session. All configurations
done via the console port can also be performed using Telnet. The user should only
open one Telnet or RS232 console session at a time. Do not use an RS232 console
session and a Telnet session at the same time as unexpected results may occur.

Fiber Optic Cleaning Guidelines

Fiber Optic transmitters and receivers are extremely susceptible to contamination by
particles of dirt or dust, which can obstruct the optic path and cause performance
degradation. Good system performance requires clean optics and connector ferrules.

Use fiber patch cords (or connectors, if you terminate your own fiber) only from

1.
a reputable supplier; low-quality components can cause many hard-to-diagnose
problems in an installation.

Dust caps are installed at IMC Networks to ensure factory-clean optical devices.

2.
These protective caps should not be removed until the moment of connecting
the fiber cable to the device. Should it be necessary to disconnect the fiber
device, reinstall the protective dust caps.

3.

Store spare caps in a dust-free environment such as a sealed plastic bag or box
so that when reinstalled they do not introduce any contamination to the optics.

If you suspect that the optics have been contaminated, alternate between

4.
blasting with clean, dry, compressed air and flushing with methanol to remove
particles of dirt.

Electrostatic Discharge Precautions

Electrostatic discharge (ESD) can cause damage to any product, add-in modules or
stand alone units containing electronic components. Always observe the following
precautions when installing or handling these kinds of products

Do not remove unit from its protective packaging until ready to install.

1.

Wear an ESD wrist grounding strap before handling any module or component.

2.
If the wrist strap is not available, maintain grounded contact with the system unit
throughout any procedure requiring ESD protection.

Hold the units by the edges; do not touch the electronic components or gold

3.
connectors.

After removal, always place the boards on a grounded, static-free surface, ESD

4.
pad or in a proper ESD bag. Do not slide the modules or stand alone units over
any surface.

WARNING!

Integrated circuits and fiber optic components are
extremely susceptible to electrostatic discharge damage. Do not
handle these components directly unless you are a qualified service
technician and use tools and techniques that conform to accepted
industry practices.
