BandwidthManager
Installation Guide
About BandwidthManager
BandwidthManager from Black Box
is a two port ,10 Mbps Ethernet networking
device that provides the ability to regulate
bandwidth bi-directionally. It is available as a
standalone unit or as an SNMP-manageable
module to be used in conjunction with Black
Box’ SNMP-manageable media conversion
chassis.
BandwidthManager features two RJ-45
data ports (labeled A and B), as well as a DB-
9 serial port for IP configuration. Both RJ-45
ports may be configured for Half-Duplex (HDX) or Full-Duplex (FDX)
operation (set this based on the capabilities of the connected hardware).
DIP Switch Settings
You can set bandwidth of the data ports on BandwidthManager for any
value up to 10 Mbps. The following instructions detail how to configure a
BandwidthManager managed via iView™, an SNMP-compatible manage-
ment application.
BandwidthManager is managed through its data ports. Before installing
BandwidthManager into your network, you may want to change the
device’s default DIP switch settings which designate which port(s) will
manage traffic (default settings shown in diagram below).

INSTALLING BANDWIDTHMANAGER
Installing BandwidthManager into a Black Box SNMP-Manageable
media conversion chassis is simple. If necessary, remove the blank brack-
et covering the slot where you’ll be installing the module. Slide the mod-
ule into the chassis, then secure the module to the chassis by tightening
the captive screws.
Configuring BandwidthManager
In order to configure and manage BandwidthManager, it is first neces-
sary to give it an IP address so that it is accessible via SNMP. There are
two ways to assign this IP information to BandwidthManager:
➤using HUBCTRL32™ through an Ethernet connection
➤via the unit’s serial port
Besides assigning an IP address and subnet mask, both methods will also
allow you to create community strings, assign access rights, configure traps
and more. However, HUBCTRL32 offers more options than the serial port
(e.g., you can select which traps to assign with HUBCTRL32).
ABOUT HUBCTRL32
HUBCTRL32 (Hub Control 32) is an in-band configuration utility that
lets users quickly and easily complete the first stages of SNMP configura-
tion for Black Box SNMP-manageable devices. Tasks HUBCTRL32 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, HUBCTRL32 offers an authorized
IP address system and access restriction to MIB groups supported by
Black Box manageable devices. These extra layers of security are purely
optional and do not effect SNMP compatibility in any way.
HUBCTRL32 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.
HUBCTRL32 works with the following platforms:
➤Windows 98™
➤Windows NT™
➤Windows 2000™
HUBCTRL32 can be found on the iView CD, or contact Black Box.

For information regarding the installation and use of HUBCTRL32, refer
to the HUBCTRL32 installation guide or the HUBCTRL32 online help file.
ABOUT SERIAL PORT CONFIGURATION
BandwidthManager’s serial port uses an IBM-compatible DB-9 serial
connector. To connect the device to your terminal/computer, use the
enclosed DB-9 cable. (If your computer/terminal has a serial port using a
connection not compatible with a DB-9 COM port, use the Pin
Connection chart below for reference in making a cable.) Plug one end
of the cable into the DB-9 connector on the device, and the other into
the appropriate port on your computer/terminal. Set your computer/ter-
minal for VT-100 emulation. The serial port on the computer/terminal
should be set for:
•38.4K
baud
•8
data bits
•1
stop bit
•No
parity
•No
flow control

ELECTROSTATIC DISCHARGE PRECAUTIONS
Electrostatic discharge (ESD) can cause damage to your add-in modules. Always
observe the following precautions when installing or handling an add-in module or any
board assembly:
1) Do not remove unit from its protective packaging until you’re ready to install it.
2) Wear an ESD wrist grounding strap before handling any module or component.
If you do not have a wrist strap, maintain grounded contact with the system
unit throughout any procedure requiring ESD protection.
WARNING! Integrated circuits and fiber optic components are extremely
susceptible to electrostatic discharge damage. Do not handle these compo-
nents directly unless you are a qualified service technician and use tools and
techniques that conform to accepted industry practices.
3) Hold boards by the edges only; do not touch the electronic components or
gold connectors.
4) After removal, always place the boards on a grounded, static-free surface, ESD
pad or in a proper ESD bag. Do not slide the board over any surface.

BandwidthManager Configuration
To configure BandwidthManager, press Space at the Main Configuration
Screen, then type bw. This will enter the configuration program for
BandwidthManager. To navigate in this program, press Zto move down, W
to move up, Ato move left, and Dto move right. Pressing Space toggles
between the Bandwidth Control section and the Duplex Mode section.
Pressing Qexits the program.
To edit the data rate for each port, you can choose one of twelve prede-
fined rates by moving the cursor to the rate you desire and pressing the S
or Enter key, or enter your own rate by choosing Custom.To choose
Custom, move the cursor to Custom, then press the Skey. Enter a rate
(between 64 bits/sec to 10,000,000 bits/sec in 1 bit/sec increments) and
then press Enter. You can choose a rate for both BandwidthManager ports
(from Port A to Port B and from Port B to Port A). Exit the program by
pressing the Qkey.
To change the Duplex setting, Space to toggle to the Duplex Setting sec-
tion when, then press Sor Enter to switch between Half- and Full-Duplex.
The default setting for duplex on Ports A and B is Half-Duplex. Duplex can
also be adjusted through iView by clicking on either Port tab.
Assigning IP Information
To modify the Saved Parameter Values (i.e., assign IP address and subnet
mask), press I. You will be instructed to enter the IP address and subnet
mask for the connected device. Press Enter after each. You may also
assign a default gateway, if desired (press Enter to skip). 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).

NOTE
Because the Delete key does not work on VT-100 terminal emulators,
use the F2 key instead to perform Delete.
NOTE
You must reboot after making any modifications to the Saved Values
or your changes will not take effect. To reboot, type the word
“Reboot” (no quote marks) at the prompt on the main configuration
screen, or turn the device’s power OFF then ON again.

Creating/Deleting Community Strings
The default community string is named “public” and has read/write
access. For security reasons, Black Box recommends you set up two com-
munities: one with read-only access (for general use), the other 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 allowed) and press Enter. Then type one of the following
options to assign the community string’s access rights:
• R= read-only access • W= read/write access • Enter = abort
Press Enter.
To delete all community strings and start over, press U. You will then
be asked, “Are you sure you want to delete all future strings?” Press Yto
proceed, Nto abort. Press Enter. Note that the above function will
delete ALL community strings. If you want to be able to selectively delete
community strings, use HUBCTRL32 to configure your device.
Assigning/Removing 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. You will
then be asked to “Enter a New IP Address.” Type the IP address of the
destination device and press Enter. Then type the name of the communi-
ty string (created earlier) and press Enter. All traps the device is capable of
will be enabled. To remove ALL trap destinations, press K. You will then
be asked if you really want to remove all trap destinations. Press Yto
continue. Press Nto abort. Press Enter.
Password Protection
You can password protect the serial configuration process by pressing P
from the main configuration screen. You will be asked to enter a pass-
word. (NOTE: Passwords are case sensitive.) Enter your password (spaces
are NOT allowed) and press Enter. You will then be asked for your pass-
word whenever you log on or off. To remove password protection, select
Pand instead of entering a password, press Enter. Should you forget the
password, use HUBCTRL32 to access the back-up copy of the PROM,
then reburn the flash PROM (or contact Black Box technical support for
assistance).
Ending Your Session
Be sure to press Ebefore disconnecting the cable in order to stop the
device from outputting to the serial port.
through 192.168.193.254, enter “192.168.193.0” for the Base IP.
Then use the Range feature to block that range of addresses (enter
“1” for Low and “254” for High).
•Multiplexing
Byte — Tells BandwidthManager exactly which byte to
multiplex the Base IP on (Afor first, Bfor second, Cfor third, Dfor
fourth) — wherever the first 0 appears. In the example above (see
Base IP), the Multiplexing Byte would be D.
•Range
— Tells BandwidthManager the Low and High of the range
of IP addresses that should be discarded/forwarded (see Base IP).
Optional (depends upon individual network configuration):
•Single
IP — A single IP address that will be excepted from the rule
set up by the filtering mode. Typically, this is the address of the
router itself.
•Multicast — Allows multicast traffic to pass when Yes is selected
(default is No).
•Broadcast
— Allows broadcast traffic to pass when Yes is selected
(default is No). To enable, select Yes, then enter the subnet mask
for the A and/or B nodes in the text box labeled “Broadcast Mask”
within the appropriate port window in iView.
LED Indicators
BandwidthManager features status LEDs for each port (as shown below).
The LED functions are:
RCV Blinks yellow when port is receiving data.
XMT Blinks green when port is transmitting data.
FDX Glows yellow when Full-Duplex mode is selected on port.
LNK Glows green when a link is established.

most often used to restrict traffic coming from LAN, through
BandwidthManager, and on to the router/Layer 3 device.
The six modes are as follows:
General Modes:
• All
Protocols — Forwards ALL traffic. Can use this mode as a
generic mode for incoming traffic to be forwarded on to the LAN.
•IP/ARP
Only — Forwards all IP/ARP traffic; blocks all other proto-
cols. Because this mode allows all IP/ARP traffic to pass through,
this is the recommended mode for traffic coming from the Internet
to the LAN.
Inclusionary Modes:
•Non-IIP/ARP,
Plus IP/ARP Range — Allows all non-IP traffic to pass;
forwards only IP/ARP packets that fall into a specified range, dis-
carding all other IP/ARP traffic.
•IP/ARP Range
Only — Like previous mode, but blocks all non-IP
traffic as well.
Exclusionary Modes:
•All
Protocols, Minus IP/ARP Range — Forwards everything except
what is specified in IP address range, including non-IP traffic.
•IP/ARP
Only, Minus IP/ARP Range — Forwards all IP/ARP packets
except what is specified in IP address range; discards non-IP traffic.
Because this is the most efficient mode for blocking unnecessary
traffic from reaching the router (unless using a non-IP protocol), this
is the recommended mode for traffic coming from the LAN to the
WAN/Internet.
Set the packet filtering mode based on the FIRST BandwidthManager
port (Port A or Port B) the traffic will come in contact with.
ADDITIONAL CONFIGURATION FOR PACKET
FILTERING MODES
When using an inclusionary or exclusionary mode, you will also need
to enter values for the following:
Required (all inclusionary/exclusionary modes):
•Base
IP — A four-byte address that tells BandwidthManager the
common portion of the IP addresses for whose packets should be
discarded (excluded) or forwarded (included), depending on mode.
To specify the Base IP, place a “0” in each byte of the address
which is NOT common to all packets. For example, if you want
BandwidthManager to block traffic for IP addresses 192.168.193.1
About iView
Once BandwidthManager is assigned an IP address, you can use iView
or another SNMP-based Network Management System (NMS) application
to configure and remotely manage BandwidthManager.
iView is a cross-platform network management application for
Black Box intelligent networking devices. It gives network managers the
ability to monitor and control Black Box’ products from virtually any 32-
bit Windows platform. iView can also function as a snap-in module for
many SNMP applications. Please consult the iView installation guide or
iView CD for assistance in installing and launching iView.
About Bandwidth Control
BandwidthManager has the ability to forward data in each direction (A
to B and B to A) at up to 10 Mbps. You can set either or both directions
to pass less than that (i.e., bandwidth control).
The bandwidth speed may be set independently for each port. As the
actual Ethernet bit rate is always 10 Mbps, the bandwidth speed limitation
for each port operates by extending the time between Ethernet packets so
that the aggregate data rate matches the bandwidth setting. The algo-
rithm used is intelligent enough to adjust “on-the-fly” to the length of
each packet, resulting in a high degree of precision (within 5%).
To set the bandwidth via iView, simply input the desired bandwidth for
this port in the Bandwidth Control section of the Port window (min: 64
bits/sec, max: 10,000,000 bits/sec). To set bandwidth via Serial
Configuration, see the Setting Bandwidth on page 4.
Packet Filtering Modes
BandwidthManager provides six modes for forwarding/discarding frames
that come in contact with the device which can be configured from the
Advanced Window in iView for BandwidthManager. These packet filtering
modes should be configured individually for each data port (A and B).
The first two modes, All Protocols (default) and IP/ARP Only, allow all
or almost all network traffic to pass through BandwidthManager. These
modes are used most often for traffic coming from the WAN or Internet,
through the router and BandwidthManager, and on to the LAN. The other
four modes use specific IP address ranges, defined by the user, to tell
BandwidthManager to either pass on or discard traffic based upon its des-
tination IP. These modes are either inclusionary or exclusionary, and are
