Black Box®LB1350A/LB1351A
1 - OVERVIEW
A media-converter may be defined as a device connecting two active network
components point-to-point over a media that is different from the ports of at least one of
these devices.
An ideal media-converter should be a transparent element in the network, and its ports
may be considered as integral parts of the devices interconnected by it.The IEE802.3u
standard defines network span in terms of distances and bit times.
Conventional 100Base-TX/100Base-FX media-converters are based on repeater
technology, and they form a part of the collision domain created by the interconnected
devices. Therefore, the delay they introduce in the network severely affects the allowed
distances. Furthermore, if two class II repeaters (i.e., 2 hubs) are already present in the
same collision domain, then the use of a conventional converter is not allowed as the
repeater count may - in such case - exceed the limits. In all other cases, meticulous
PDV (Path Delay Value) must be performed prior to establishing the possible distances
for both the fiber optic (F/O) and copper segments.
The Black Box®LB1350A/LB1351A family implements a non-repeater, full re-timing
approach. It creates a Buffered Media Domain (BMD) over the F/O link, thereby
eliminating all the above mentioned limitations.
The BMD created by two Black Box®LB1350A/LB1351A devices always operates at
maximum performance - 100Mbps/Full Duplex - while interconnected devices may
operate at different rates and modes. This provides full flexibility when planning a
network.
The Black Box®LB1350A/LB1351A provides 4 (3) TP ports sharing conversion to one
FO port, with the TP ports buffered and VLAN protected between themselves, making
the device an ideal and most economical solution for both FTTH (Fiber-To-The-Home)
and FTTD (Fiber-To-The-Desk) applications.
2- Planning your Network with Black Box®LB1350A/LB1351A

The Black Box®LB1350A/LB1351A will not only convert signals from copper to fiber
but also from 10 to 100Mbs and HDX to FDX, thus ensuring maximal distance over the
optical link.
All you need to take care of is the Speed and Duplex mode balance across the network:
if one of the local devices is HDX only capable you should force the corresponding
remote device to HDX as well to avoid buffer overflow. Same applies to devices with
10Mbps capability only.
Disregarding the interconnected device F/O link will always operate at 100Mpbs and
FDX (you may force it to HDX as well, if needed )

Black Box®LB1350A/LB1351A
General Description
The Black Box®LB1350A/LB1351A is a shared and buffered media converter. It
converts 100Base-FX signals received on its F/O interface in 10/100Base-TX signals
and distributes them to 4(3) copper (shielded RJ-45) ports. Each of these ports is
buffered; furthermore, factory set VLAN forms groups each including one copper port
and the common F/O port, providing the users with basic security (no connection
between the users). This architecture allows 4(3) users to share one F/O link with
dramatic (up to 75%) savings.
The copper ports are auto-negotiating and will automatically adapt themselves to the
capacity of the users for highest performance (will negotiate 10/100 and FDX/HDX).
Nevertheless, in some cases it may be necessary to force certain operating modes.
For this purpose, all copper ports may be (individually) forced to 10Mbps/FDX
operation and port #4(3) (the preferred port) may be forced to any desired combination
(altogether 4 combinations) of HDX/FDX and 10/100.
Full front panel diagnostics provide information on the operation mode of every port.
The F/O port is configured by default to FDX but if desired may be set to HDX as well.
However it is essential to remember that when in HDX, the F/O link maximal distance
drops to 412m or less.
The Black Box®LB1350A/LB1351A is available with a variety of multi-mode and single-
mode interfaces with distance ranging from 2km to 40km.
The Black Box®LB1350A/LB1351A is packaged in a rugged “half rack” enclosure
allowing elegant and safe deployment in a variety of environments: desktop, 2 units on
a 19” rack-shelf or within a standard “half 19” rack (optional brackets required).
Its internal, high-power auto- range switching power supply ensures easy, safe and
error-free deployment and enhanced MTBF.
The managed version – Black Box® LB1351A – provides full in-band SNMP
manageability (both monitoring and control) - see Appendix A ( pages 19-37 )
Port priority schemes are also a part of the management.
5. PREFERRED PORT
TP port #4 of the Black Box®LB1350A (or #3 of the Black Box® LB1351A) provides
additional functionalities comparing to the other copper ports.
Full operation mode selection
While all the TP ports provide auto-negotiation and forced 10Mbps/FDX operation, this
preferred port may be set via the front panel DIP switches to force all possible operation
mode options: 10/HDX, 10/FDX, 100HDX and 100FDX. See section 12 for detailed
Dip switches setting ( page 14 ).
Recommendation: use the preferred port for connection of the most critical or
heavy traffic user of the four, even if you do not implement the special features
described above
6. Far End Fault Signaling ( FEF ) feature
When the device detects F/O Link Loss (receive side) it automatically sends a Far End
Fault signal to the remote device. If such device is another Black
Box®LB1350A/LB1351A or any device which supports such feature – then it will
indicate F/O Link Loss as well. By activating TEST mode (by TEST switch - #8 MODE
SETUP Dip switches on the front panel ) this function may be disabled .The picture
below depicts this functionality.

Black Box®LB1350A/LB1351A
If there is a fault in the outgoing path and the remote device is FEF compliant (see
below) then the F/O LINK LED will go OFF on both the local and remote devices. In this
way we avoid the possibility of having a FX Link ON indication at one end while, in
reality one of the data path is disrupted.

Black Box®LB1350A/LB1351A
14. ADVANCED Features: Port Priority Schemes
The Black Box® LB1351A (only)can determine priority through three different
means.
The first method is a simple per port priority, the second is via the
802.1p frame tag and the third is by viewing the DSCP ( TOS ) field in the
Ipv4 header. Two priority levels are deployed ( High and Low )
Per Port Priority
General priority can be specified on a per port basis. In this type of priority
all traffic from the specified input port is considered high priority .
This can be useful in IP phone applications mixed with other data types . The IP phone
traffic would be high priority .
802.1p Port Priority
This method works well when used with ports that have mixed data and media flows.
The 802.1p priority tag ( 3 bits ) are used to determine frame priority. The inbound port
examines the priority field in the tag and determines the high or low priority.
VLAN tagging and priority. When frames are sent across the network, there needs
to be a way of indicating to which VLAN the frame belongs. This info is added to
the Ethernet frame in the form of a tag header.
Ethernet Frame Tag Header consists of a Tag protocol identifier ( TPID ) and Tag
control information ( TCI )
Ethernet frame :

User priority is a 3 bit field which allows priority information to be encoded in the
frame. 8 levels of priority are allowed, where zero is the lowest and 7 is the highest
priority.(this field is used by 802.1p )
CFI : indicates presence/absence of RIF ( routing info field ) in the 802.3/Ethernet
frames.
The VLAN ID is used uniquely to identify the VLAN to which the frame belongs.
There can be a maximum of 4096 VLANs.
DSCP Port Priority
This is another per frame way to determine outbound priority.
The DSCP ( Differentiated Services Code Point – RFC 2474 ) method uses the
TOS
field in the IP header to determine high or low priority on a per code point basis.
Each fully decoded code point can have either a high or low priority.
The most significant 6 bits of the TOS field are fully decoded into 64 possibilities,(
up to 64 distinct behaviors ) and the resulted singular code is compared against the
corresponding bit in the DSCP register. ( in Black Box® LB1351A unit )
15

Black Box®LB1350A/LB1351A
If the register bit is a 1, the priority is high and if 0, the priority is low.
Thus the DSCP value classifies the packet service level.
When more than one scheme is enabled, priority conflicts are resolved by the
following order : 802.1p based priority overrides port based priority and TOS based
priority overrides 802.1p based priority

Appendix-A : Managing the Black Box® LB1351A
1.Preface
This appendix provides you with the necessary information for managing the
Black Box® LB1351A Traffic Aggregator (monitor and control).
In order to start managing your Black Box® LB1351A you need to setup the
management module parameters (section 2). In addition you will need to set proper
network connection (section 3) and to install the attached MIB file (section 4).
After the management parameters are set, you can manage the Black Box®
LB1351A in either of two ways: using SNMP (through a standard management
station – section 5) and using a Terminal (section 6).
2.Setting Up Management Parameters
Terminal connection
Have available a PC equipped with any terminal emulation program (any ASCII
terminal).
Use the supplied control cable to connect the converter to the PC: connect the
miniDIN end of the cable to the RS232 port on the converter and the other end to
an available DB9 (male) connector on the PC.
Configure the terminal emulation program as follows:
• baud rate: 9600
• parity: none
• start bits: 1
• stop bits: 1
• flow control: none
Start the terminal emulation then reset the device.
Startup screen
After a few seconds you will get the start up screen (figure 2-1).
Note: the parameters appearing in the figures are just examples. Set them to
the values you need.
At this point, you should immediately press any key in order to get to the
management configuration procedure. You will get a notification that will enable you
to modify the current settings by typing ‘m’ (or ‘M’).
At this stage you will be prompted with a series of questions regarding the
management parameters configuration. The configuration procedure screen is
shown here in figure 2-2. Default value for each parameter appears in braces. If you
do not wish to change a certain parameter, simply hit ‘Return’.The different
parameters are explained in detail in figure 2-2. Default value for each parameter
appears in braces.If you do not need to change a certain parameter, simply hit “
Return “.The different parameters are explained in details in figure 2-2.

Black Box®LB1350A/LB1351A
3.Network Connection
One of the conditions that have to be met before you’re able to manage the Black
Box® LB1351A is to have the device connected to a network (IP).
This connection is achieved through the Fiber-Optic port of the device. Naturally, this
port has to be connected to a network, on which the management station resides.
Please note that all management traffic is in-band, along with normal traffic.
At this point your Black Box® LB1351A is ready to be managed by any Network
Manager running on the network. In order to obtain full management functionality over
the Black Box® LB1351A, you should install the MIB file and define the Black Box®
LB1351A object in the management application (see next section).
Important: if you wish to manage the device (and/or other devices in the network) by
connecting the management station directly to one of the device’s RJ-45 ports, you
MUST disable per port VLAN first (switch # 10 to UP position)!
4.Configuring the Management Station
Before you can begin to fully manage the Black Box® LB1351A from a management
station using SNMP, you need to load and compile the MIB file(s), included with the
management module, onto the management station.
In order to accomplish this you need to perform two steps:
Copy the MIB file, supplied with the module, to the default directory that contains all
other MIB files (varies between management software packages).
In your management application, add the new MIB to the already existing list of MIBs
and recompile them.
After MIB installation you should define a new managed object for the Black Box®
LB1351A according to the SNMP parameters you have previously set. The way to
define this object varies from one management application to another.
You have now completed all the necessary preparations required to fully monitoring
and controlling the Black Box® LB1351A from any management station on the
network.

Black Box®LB1350A/LB1351A
5.Managing the Black Box® LB1351A
You can monitor and control the Black Box® LB1351A Traffic Aggregator using SNMP
with a management station. This station must have a management application and it
should be connected to the device (via the network).
After the device and management station are connected and running you will be able
to manage your device through the SNMP management application.
Use the management application to view the device’s general information (figure 5-1)
or the MIB tree for detailed status (figure 5-2). In order to monitor the device’s status
you should open the following branch of the tree:
enterprises/fibrolan/fibrolanSNMP/fibrolanAggregator/flAggrLta31m
Through the various parameters given within the Black Box® LB1351A’s MIB, you can
view the complete device status and the ports’ status and you can configure most of
these parameters.
The Black Box® LB1351A is a fully featured traffic aggregator that provides advanced
capabilities such as VLAN tag insertion and stripping and an advanced set of priority
schemes. These features are explained in details later on in the ‘Managing with a
terminal’ section. All settings are also accessible through SNMP and their meaning is
the same (so the complete detailed explanation about each parameter is found only in
the terminal section).
Note: some configuration changes (mainly port connection and disconnection)
require a few seconds to take effect.

6. Managing with a Terminal
The first option for managing the Black Box® LB1351A Traffic Aggregator is by using a
terminal emulation program. In order to do this you will need a PC (or a terminal) with a
terminal emulation program.
Connect the serial cable supplied with the Black Box® LB1351A between the device
(miniDIN side) and a serial port on the PC with the terminal emulation (on the DB9
side). Start the emulation program and reset the device (recommended).
After system initialization you will get to the device’s main menu.
The main menu
This menu contains a header with the software version, the model of the device
(LB1351A ) and the vendor Black Box.
Following is a two-option menu. See figure 6-1.
Selecting option 1 will invoke the device’s status menu, while option 2 will bring up the
device control menu.

Black Box®LB1350A/LB1351A
Advanced status
A port’s advanced status includes, in addition to its number and type:
• Tag insertion mode (Yes/No)
• Tag stripping mode (Yes/No)
• Port’s VID (0-4095)
• Port based priority (Yes/No)
• 802.1p based priority (Yes/No)
• TOS based priority (Yes/No)
• Port’s user priority (0-7)
When tag insertion is enabled on a port it means that any untagged frames coming out
that port will be tagged. The inserted tag will include the ingress port’s VID and user
priority. For example, if port 1’s VID is set to 100 and its priority is set to 4 and the FO
port’s tag insertion is on, then any untagged frame coming on port 1 and going out the
FO port will carry a tag with VID 100 and priority 4.
When tag stripping is enabled, any tagged frame coming on the port, will lose its tag.
Default values are all 0s or No.
The Black Box® LB1351A supports 2 levels of traffic priority: high and low. The
different priority settings enable or disable 3 different types of priority schemes: port
based, 802.1p based and Type Of Service (TOS) based, dealing with DSCP (Diff Serve
Code Points) field values.
When more than one scheme is enabled, priority conflicts are resolved by the following
order: 802.1p based priority overrides port based priority and TOS based priority
overrides 802.1p based priority. Default values are all No.
Please note that the advanced port settings apply to management traffic as well.
Management can be thought of as a virtual, internal port.
The device’s advanced status consists of:
• Test mode (FEF disable/enable)
• Priority ratio (always hi/10:1/5:1/2:1)
• Broadcast protection (allow 25/12/6/3%)
• DSCP codes (64 bits)
• User priority classification (7 priority codes, set as high or low priority)
The test mode is used mainly for maintenance purposes and its meaning is that the
FEF function is disabled (when Test is On). Default value is Test Off.
The priority ration setting controls the priority traffic flow ratio. If for example, set to
always hi, all high priority frames will be forwarded before low priority ones. At 10:1,
after every 10 high priority frames, a single low priority frame will be forwarded and so
on. Default value is always hi.

Black Box®LB1350A/LB1351A
The broadcast protection indicates the relative amount of broadcast traffic that will be
forwarded by the Black Box® LB1351A, starting at 25% maximum and down to 3%
minimum. Default value is 25%.
The DSCP codes are represented as a series of 8 bytes, corresponding to 64 bits.
These bits correspond, in turn, to 64 different DSCP codes. If you wish, for instance, to
set code 45 as high priority, then bit 45 in this series needs to be set to ‘1’ (this is done
though the control menus, described later). Default values are all 0s (meaning all codes
are low priority).
The user priority codes are used in conjunction with the 802.1p based priority scheme.
For example, if a tagged frame arrives with a priority code of 6, the Black Box®
LB1351A will look priority code 6 to see if it is set as high or low priority and handle the
frame accordingly. Default values are low priority for codes 0-3 and high priority
for codes 4-7.
The device control menu
The device control menu, shown in figure 6-5, enables the user to change the different
settings and configuration of the Black Box® LB1351A
Device control:
===============
1. TP port 1 control
2. TP port 2 control
3. TP port 3 control
4. FO port 4 control

switches position). Options 6 and 7 will bring up the device control menu, respectively
and the eighth option will get you to the management virtual port’s settings.
All control functions are located in the same tables of the device’s MIB sub-tree as their
corresponding status. The only exception is the management control functions, which
reside in the same table as the advanced device status.

Changing the device’s Test mode will enable or disable its FEF function (Test off/Test
on, respectively). Please note that during normal operation this should be set to Test off
(FEF enabled).
When you choose to bind/split ports (options 2 and 3), you will be prompted whether
you wish to bind or split the ports. Binding the ports means they will reside in the same
port based VLAN, resulting in the ability to directly communicate with each other
(assuming no other factors, such as different tagging setup, interfere). Splitting the
ports will undo this operation. This option can only take effect when the VLAN mode
is ‘enabled’.
Selecting option 4 will prompt the user with the priority ratio mode selection menu
(figure 6-11 )
Hi/Low priority ratio:
1. Always Hi first
2. Transmit at 10:1 ratio
3. Transmit at 5:1 ratio
4. Transmit at 2:1 ratio
0. Skip without changing

Choosing to set the broadcast protection mode will prompt the user for the desired
setting (figure 6-12).
Broadcast protection:
1. Allow 25% broadcast frames
2. Allow 12% broadcast frames

If you wish to change the DSCP codes or the 802.1p priority classification you will be
prompted for the DSCP code or priority code and the corresponding value, as shown in
figures 6-13 and 6-14, respectively.
DSCP configuration:
Select DSCP code (0-63) or 64 to skip: 28
Select hi(1) or low(0) priority for DSCP 28: 1
figure 6-13 – DSCP configuration change
802.1p user priority classification:
Select priority code (0-7) or 8 to skip: 3
Select hi(1) or low(0) priority for priority 3: 1
figure 6-14 – 802.1p priority classification change
Choosing the last option (8) of the advanced device control menu will cause the device
to return to its default settings and restart. This may require a few seconds to complete.
The default values are given in the status section. It is recommended to reset the
device after this operation.
Management control menu
The management control menu (figure 6-15) provides the same options as other
advanced port priority menus. These settings apply to in-bound and out-bound
management traffic going through the ‘virtual management port’. Consider them as if
they apply the same way as they do with any other port.
Management control:
===================
1. Enable/Disable tag insertion
2. Enable/Disable tag stripping
3. Set VLAN ID
4. Enable/Disable priority
5. Enable/Disable 802.1p priority
6. Enable/Disable TOS priority
7. Set user priority
0. Back to port control menu
Select (0-7):
figure 6-15 – management control menu
Note that changing some settings (such as the VLAN ID) may cause management traffic
to be stopped, thus disconnecting the management station from the device.
Please note that the VLAN related features (namely, tagging options) would take effect
when the VLAN mode is ‘enabled’.

7.Managing with SNMP
When you wish to manage the Black Box® LB1351A with SNMP using a management
station, you should have the relevant MIB file (“bbLB1351A.mib”) installed and
compiled on any standard management application.
Once you have the appropriate network connection for managing the device you can
start getting the device parameters’ status and changing its settings.
Note that the meaning of each parameter is the same as its corresponding one in the
menus. You can therefore find the detailed explanations regarding these parameters in
the previous (terminal) section.
Note that viewing a parameter and setting its value is done in the same place in the
table (the method for setting might differ from one management application to another).
System info
Figure 7-1 shows the basic, MIB standard, system info table. It is accessible through
the standard’s MIB system info table.
