About the AccessEtherLinX

The AccessEtherLinX 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, AccessEtherLinX
provides
differentiating and separating

a VLAN-based Layer 2 entry point to the MAN fiber network, trunking,

customer traffic. Featuring SNMP management,
bandwidth control, QoS, traffic prioritization and multicast pruning (using IGMP v1,
v2), it is an ideal

solution for delivering Ethernet-based services to customers quickly

and cost-effectively.

AccessEtherLinX also features Telnet, and firmware upgrading through serial
configuration or Telnet via a TFTP server.

The AccessEtherLinX/4 includes
twisted pair),

four 10/100 twisted pair Ethernet downlink ports (for connecting

one Uplink port (either 100Base-FX fiber or 10/100

users/LANs) and an internal 100 - 240 ±10% AC power supply.

The AccessEtherLinX/3 includes one Uplink port (either 100Base-FX fiber or 10/100
twisted pair) and three 10/100 twisted pair Ethernet ports (for connecting
users/LANs). It also employs a universal, external switching power cube with 100 to
240 ±10% VAC input and 5V DC output.

Single-strand fiber versions of the AccessEtherLinX/4 and /3 are also available.

Note

The generic term “AccessEtherLinX” refers to both the AccessEtherLinX/3 and
AccessEtherLinX/4.

Installing the AccessEtherLinX

The AccessEtherLinX comes ready to install; there is no hardware configuration
required. All features, such as FiberAlert and Auto-Negotiation, are software
configurable.

Refer to the help file for configuration information. Place the AccessEtherLinX on a
flat surface, prior to installation. Attach the cables between the AccessEtherLinX and
each device that will be interconnected, then plug the unit into a reliable, filtered
power source.

Wall-Mount Installation

To wall mount the AccessEtherLinX/3, use the supplied screws to attach the wall­mount bracket to the AccessEtherLinX/3, then mount the unit to the wall. Attach the
cables between the AccessEtherLinX and each device that will be interconnected,
then plug the unit into a reliable, filtered power source.

1

Rack-Mount Installation

p

A rack-mount kit can also be ordered, which includes two brackets that screw onto
either side of the AccessEtherLinX/4. Once the brackets are attached to the unit,
install the AccessEtherLinX/4 into the rack.

Features

Autocross Feature For Twisted Pair Connection

All twisted pair ports on the AccessEtherLinX include AutoCross, a feature which
automatically selects between a crossover workstation or pass-through connection
depending on the connected device.

INSTALLATION TIP

Since 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 TX/4+SSFX­SM1310-SC (1310 xmt and 1550 rcv), for exam

le, to a product with 1550 xmt and
1310 rcv, e.g TX/4+SSFX-SM1550-SC (1550 xmt and 1310 rcv) The two connected
products must also have the same speed and distance capabilities (i.e. both are
single-mode [20km] or both are single/PLUS [40km]).

Software Configurable Features

The FiberAlert, Auto-Negotiation (Selective Advertising) and Bandwidth Control
features are all configurable via the management software or via serial configuration.

Refer to the AccessEtherLinX help file for software configuration information, or see
the section in this document for Serial Configuration information.

About FiberAlert

The AccessEtherLinX includes an advanced troubleshooting feature, FiberAlert, which
minimizes the problems associated with the loss of one strand of fiber. If a strand is
unavailable, the AccessEtherLinX notes the loss of link. The device will then stop
transmitting data and the link signal until a signal or link pulse is received. The result
is that the link LED on both sides of the fiber connection will go out, indicating a fault
somewhere in the fiber loop. Using FiberAlert, a local site administrator is notified of
a fault and can quickly determine where a cable fault is located.

2

Note

FiberAlert is not available/applicable on single-strand fiber products.

Auto-Negotiation, Duplex Mode And Speed

The twisted pair ports on the AccessEtherLinX 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 does not auto-negotiate; it always
operates at 100 Mbps Full-Duplex.

Auto-Negotiation

The AccessEtherLinX ships with Auto-Negotiation enabled on the twisted pair ports.
In this mode, the twisted pair port negotiates for speed and duplex.

Forcing the Speed and Duplex Mode

The twisted pair downlink ports on the AccessEtherLinX/4 can also be manually set
for 10 Mbps or 100 Mbps operation and for Half- or Full-Duplex (i.e. 10 Mbps Full­Duplex, 10 Mbps Half-Duplex, 100 Mbps Full-Duplex or 100 Mbps Half- 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 Force Mode, when connecting to devices that ONLY auto-negotiate.

Bandwidth Control

The AccessEtherLinX includes bandwidth control functionality. Bandwidth can be set
independently, in 32 Kbps increments, on each downlink port, or bandwidth can be
for the unit by assigning the uplink port a given amount. Refer to the help file for
software configuration information.

About iView²

iView² is a cross-platform network management application for intelligent networking
devices. It features a graphic user interface (GUI) and gives network managers the
ability to monitor and control devices from virtually any 32-bit Windows platform.
iView² can also function as a snap-in module for many SNMP applications. Refer to
the help files for iView² and AccessEtherLinX for information regarding configuring
and managing the AccessEtherLinX.

3

About iConfig

iConfig is an in-band configuration utility that lets users quickly and easily complete
the first stages of SNMP configuration for SNMP-manageable devices. Tasks iConfig
can perform include:

Setting the IP address, subnet mask and default gateway

•

•

Defining the community strings and SNMP traps.

In addition to the above functions, iConfig offers an authorized IP address system and
access restriction to MIB groups supported by manageable devices. These extra
layers of security are purely optional and do not affect SNMP compatibility in any
way.

iConfig can also be used to upload new versions of the system software and new MIB
information. It also offers diagnostic capabilities for faster resolution of technical
support issues. iConfig version 1.3 or above MUST be used for PROM updates.
HubControl32 and previous versions of iConfig will not work.

iConfig works with the following platforms:

Windows 98

•
Windows NT

•

•

Windows 2000
Windows XP

•

The iView² CD shipped with the AccessEtherLinX includes iConfig. For information
regarding the use of iConfig, refer to the iConfig help file.

SNMP Management

SNMP management and iConfig are always through the AccessEtherLinX Uplink port.
This provides a higher level of security so end-users cannot access management, alter
settings, etc.

Assigning IP Information

In order for the AccessEtherLinX to allow for SNMP-management, the unit must be
assigned IP configuration information (e.g., IP address, subnet mask, etc.) using
iConfig via iView²; the unit’s serial port or DHCP (Dynamic Host Control Protocol).
In addition to assigning an IP address and subnet mask, the former two methods will
also allow users to create community strings, assign access rights, configure traps and
more. However, iConfig offers more options than serial port configuration.

After assigning an IP address, use iView² or another SNMP-compatible Network
Management System (NMS) to remotely configure, monitor and manage the
AccessEtherLinX.

4

About Serial Port Configuration

Use the supplied RJ-45 to DB-9 adapter on Downlink Port 4 on the
AccessEtherLinX/4 or Downlink Port 3 on the AccessEtherLinX/3 to allow for serial
port configuration. This adapter uses an IBM-compatible DB-9 serial connector.

To connect the AccessEtherLinX to a terminal/computer, use a straight-through (pin­to-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 belowfor
reference in making a cable.) Make sure the cable length is under 50 feet (15.24 m).
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

38.4K baud, 8 data bits, 1 stop bit, no parity

and

no flow control

VT-100 emulation

Assigning TCP/IP Information

To modify the Saved Parameter Values (i.e., assign IP address and subnet mask), press
I. Enter the IP address and subnet mask for the connected device, pressing Enter after
each value. A default gateway can also be assigned (press Enter to skip). When
finished, press Enter, then type Reboot for the changes to take effect. The Saved
Values and Current Values should now both display the changes made (e.g., new IP
address and subnet mask).

Creating Community Strings

The purpose of community strings is to add a level of security to a network. The
default community string is named “public” and has read/write access. Delete this,
then adding the necessary custom communities strings such as one with read-only
access (for general use), and another with read/write access (for the administrator).
To create a new community string, go to the main configuration screen and press C.
Enter the name of the new community (up to 16 characters, no spaces) and press
Enter. Then type one of the following to assign the community string’s access rights:

R = read-only access

•
W = read/write access

•
Enter = abort

•

Press Enter. When finished, press Enter, then type Reboot for changes to take effect.
The Saved Values and Current Values should now both display the changes made
(e.g., new IP address and subnet mask).

Deleting Community Strings

To delete all community strings and start over, press U. When asked, “Are you sure
you want to delete all future strings?”, press Y to proceed or N to abort. Press Enter.

This function will delete ALL community strings. Use iConfig to selectively delete
community strings.

Assigning Trap Destinations

Traps are sent by the manageable device to a management PC when a certain event
takes place. To enter a trap destination, press T. When asked to “Enter a New IP
Address.”, type the IP address of the destination device and press Enter. Then, type
the name of the community string (that the destination device has been configured to
accept) and press Enter. This function enables ALL of the device’s traps. To
selectively activate and de-activate traps, use iConfig for configuration. Supported
traps are Enterprise specific and include: Link Down, Link Up, Cold Start, Warm Start
and Authentication Failure.

7

Removing Trap Destinations

To remove all trap destinations, press K. When asked to confirm, press Y to continue
or N to abort. Then, press Enter.

Password Protection

The serial configuration process can be password protected by pressing P from the
main configuration screen. Then, enter a password (Passwords are case sensitive with
no spaces allowed) and press Enter. This password will be requested whenever
logging on or off. To remove password protection, select P and, instead of entering a
password, press Enter. Use iConfig to access the back-up copy of the PROM in the
event of a forgotten password, then re-burn the flash PROM (or contact technical
support for assistance).

Ending a Session

Be sure to press E before disconnecting the cable in order to stop the continuous
stream of data to the serial port.

Configuring VLAN IDs

LANs consist of devices that are grouped within a certain physical proximity. Virtual
LANs (VLANs) allow devices in different LANs to communicate with each other as if
they were part of the same LAN. The AccessEtherLinX is VLAN compatible, with the
ability to accept traffic containing 802.1q VLAN tags on the Uplink port and direct
that traffic to the twisted pair downlink ports or to management based on a VLAN ID.
When using VLAN IDs, the SNMP must be assigned an ID or else the management
and pinging features will not be available.

To configure VLAN IDs, press the Space Bar when in the Command List section of
the Main Configuration screen (serial configuration). VLAN is an available option.
Type vlan and press Enter for VLAN Configuration.

9

Note

Decide whether the unit will be in dlsecure mode or dl_open mode. Configure as
desired and reboot. Use dl_open to configure multiple VLAN IDs on multiple ports.

When the VLAN functionality is NOT already enabled, the following screen will
display:

*** VLAN ID And Port VLAN Membership Configuration Screen ***

This device is not currently in VLAN Mode.

To enable VLANs, define one or more VLAN IDs,
and make sure that at least one port (typically UpLink)
is marked for TAGs!

Press <Enter Key> to enter VLAN definition mode.
Press any other key to exit.

Pressing Enter enables VLAN functionality and opens the VLAN Definition screen. To
disable VLAN functionality, delete all settings in the VLAN Definition screen.

INSTALLATION TIP

A reboot must be performed after defining/changing VLAN ID information.

To change VLAN functionality, when VLANS are enabled, type vlan and press Enter
to open the VLAN Definition screen (refer to the screen examples in the “dl_Open
Mode— Configuring Multiple VLAN IDs Per Port“ and “Configuring a VLAN ID for
Each Port” sections).

Users can define up to 15 VLAN IDs. Valid VLAN IDs are 1 to 4,094.

Note

SNMP can only be a member of one VLAN ID. Tags cannot be enabled on SNMP
traffic. Users can assign each port plus SNMP a priority in the VLAN Definition
screen. The high and low priority is determined by the Base VLAN of the unit. Use
iView² to set the Base VLAN priority; this value is not configurable via a serial/Telnet
session.

accept VLAN tagged traffic. Assign up to 15 VLAN IDs to the Uplink port, then assign
one of those VLAN IDs to each Downlink port and SNMP.

11

Base VLAN Priority

The Uplink port has two outgoing queues; one for high priority traffic and one for low
priority traffic. iView² can set a Base VLAN Priority to designate what will be high
priority and low priority. If the Base VLAN Priority is 4, 0-3 are low priority and 4-7
are high priority. If the Base VLAN Priority is 3, 0-2 are low priority and 3-7 are high
priority. In the VLAN Configuration screen (shown above), a Priority (0 - 7) can be
entered for each port and SNMP.

Downloading Files

Firmware can be downloaded from a central server via the TFTP protocol. This
download can be initiated via serial configuration or Telnet session. Make sure the IP
Address and the name of the file to download are correct in the Current Values
section of the Main Configuration screen. To download a file, press the Space Bar
from the Command List section of the Main Configuration screen (serial
configuration). Type download and press Enter to open the Download a File screen.
This screen displays the IP Address of the TFTP server and the name of the file to
download. Press Enter to start downloading the file.

If the download is interrupted, do not reset the module or reboot the chassis. Close
the session, then open a new TFTP session.

Note

This screen shows the settings for the AccessEtherLinX/4 and includes information
for the unit’s four downlink ports; the same screen for the AccessEtherLinX/3 will
show information for the unit’s three ports.

Using Telnet

Assign the AccessEtherLinX an IP address before using a Telnet session. All
configuration done via the serial port can also be performed using Telnet. Use only
one Telnet session at a time. Do not use an RS-232 serial session and a Telnet
session at the same time.

About DHCP

The AccessEtherLinX comes with a DHCP client. It is disabled by default. If a DHCP
server is present on the network, the DHCP client will initiate a dialogue with the
server during the boot up sequence. The server will then issue an IP address, Default
Gateway and Subnet mask to the AccessEtherLinX chassis. Once the new IP address
is received, the AccessEtherLinX will reboot so that the new IP address will take
effect. See the About Serial Port Configuration section for more information. If there
is no DHCP server on the network, use iConfig or serial configuration to manually set
the IP addresses.
