Chapter 1 - Introduction  
About the BR Router  
Congratulations on your purchase of the BR Router Ethernet to wide area router.  
The BR Router supports the IP, IPX, AppleTalk, and DECnet protocols, with dial-  
on-demand or dedicated line operation over voice, leased/switched, or ISDN lines,  
using the PPP and/or the Frame Relay wide area protocols.  
This manual will help you install the BR Router to connect your local Ethernet to a  
wide area network. The wide area network may be connected to other DCB routers,  
or to routers from other vendors. You can also use the BR Router to connect your  
network to an Internet Service Provider.  
In short, the installation steps are:  
1. Install the BR Router hardware and connect it to a line communication device  
(including a modem, CSU/DSU, or ISDN Terminal Adapter).  
2. Select the management method you wish to use with the router. If you want to  
use the RouterView management software, you must install the software on a  
Windows PC or Macintosh computer which is connected to your network.  
3. Configure the BR Router LAN and WAN parameters using the management  
method you have chosen.  
If you have any difficulties during the installation or use of the BR Router that are  
not answered by this guide, please call DCB or your BR Router reseller. DCB’s  
phone number is listed on the front of this guide. We will be happy to help you.  
The manual is divided into several sections that should provide you with all the  
information you will need to use the BR Router on your network.

Warranty registration card  
v Note: Some routers may be shipped with two RS-232 “Y” cables. These cables  
can be used for both data and auxiliary port operation.  
Needed For Installation  
Before connecting the BR Router to your network, you need to make sure that you  
have the necessary equipment for connecting to the local Ethernet and the wide area  
transmission device(s) (modem, CSU/DSU, ISDN terminal adapter).  
Ethernet Connection Requirements  
The BR Router’s Ethernet port directly supports thick, thin and 10BaseT twisted-  
pair Ethernet. Switching among the three ports is automatic – simply plug the  
proper Ethernet connector into its port. Other Ethernet cabling types (such as fiber  
optic cabling or pre-10BaseT twisted-pair) can be supported using adapters which  
connect to a thick Ethernet port.  
Thick Ethernet  
To connect the router’s Ethernet port to a standard (thick) Ethernet cable you will  
need a transceiver cable connection at the correct location on your Ethernet cable.  
The transceiver cable will attach directly to the DB-15 connector on the router.  
Thin Ethernet  
To connect the router’s Ethernet port to a thin Ethernet cable you will need a T-  
connector installed at the correct location on your Ethernet cable. A T-connector is  
required for proper termination of the cable.  
10Base-T Twisted-Pair Ethernet  
To connect the router’s Ethernet port to twisted-pair Ethernet cabling you will need  
an unshielded twisted-pair wire that is connected to a 10BaseT-compatible twisted-  
pair hub.  
v Note: Ethernet cables and cable connectors are not supplied with the BR Router  
product. Please contact your reseller or your DCB representative for information  
on obtaining the correct Ethernet cabling supplies.  
 
11  
v Note: These hardware installation instructions assume that your Ethernet cabling  
is already in place. Thin coaxial Ethernet network cabling should be terminated at  
each end with 50 Ohm terminator plugs. A T-connector or transceiver must be  
available in the location where you will be installing the router.  
Telco Line Connection Requirements  
The BR Router is not a line communications device. In order to connect to a wide  
area transmission line, you must use a modem, CSU/DSU, or ISDN Terminal  
Adapter. Which of these devices you use depends on the type of wide area line to  
which you are connecting.  
v Note: Before attempting to connect the BR Router to a leased telco line, use the  
loopback features of your CSU/DSU’s to check the line. This can save you a  
considerable amount of time, since the more equipment you have on the line, the  
more difficult it becomes to determine where a problem is occurring.  
RS-232 Port  
No matter which type of wide are line you plan to connect to, the line  
communications device you use must provide an RS-232 connection in order to be  
used with the BR Router.  
The BR Router includes one DIN-8 to DB-25 RS-232 sync/async data cable. This  
cable supports RS-232 asynchronous modems, synchronous leased and switched-  
CSU/DSU’s, and North American ISDN Terminal Adapters.  
Some Japanese and European terminal adapters may require an adapter plug. For  
more information, contact DCB.  
v Note: Please use only this cable when connecting your line communication  
device to the BR Router. The cables provided with other equipment do not provide  
all of the connections required between connector pins for correct hardware  
handshaking and synchronous clocking.  
 
 
13  
Chapter 3 - Hardware Installation  
BR Router Back Panel  
This section of the manual describes how to connect the BR Router to your Ethernet  
network and your wide area communications device. In summary, the steps for  
installation are:  
1. Make sure the router is powered down and the power supply is not plugged  
in to the wall.  
2. Wall mount the router, if required.  
3. Connect the router to the Ethernet network.  
4. Connect the router to the wide area line communications device.  
5. Power up the line communications device.  
6. Plug in the power supply and power up the router.  
Mounting the Router  
The BR Router can be left standalone on a desktop or equipment table, or can be  
wall mounted.  
v Note: Wall mounting requires a wall-mount bracket kit (part number A00-0987)  
from DCB.  
For wall mounting, follow the instructions included with the wall-mount bracket  
kit.  
 
14  
Connecting the Router to the Ethernet  
For thick and thin Ethernet networks you should have installed your Ethernet  
cabling before you install the BR Router.  
If you have a coax installation, the Ethernet network cable should be terminated at  
both ends with 50 Ohm network terminating resistors, and a T-connector or  
transceiver should be available at the location where you will connect the router.  
If you are installing a twisted-pair connection, and the twisted-pair hub is already in  
place, or a T-connector or thicknet transceiver is already installed on your Ethernet  
cable, you can connect the router to an active network without interrupting network  
activity.  
The BR Router’s Ethernet interface features all three media connector types. The  
active media connection will automatically be selected when you attach a cable.  
Do not terminate inactive connectors on the router, as this may cause an  
incorrect media type to be selected.  
Connecting to Thick Ethernet  
To connect the router to a thick Ethernet network, simply plug one end of a  
transceiver cable into the DB-15 transceiver connector located on the back panel of  
the unit. Then, plug the other end of the transceiver cable into the transceiver  
which should already be attached to the thick Ethernet cable.  
Connecting to Thin Ethernet  
In order to connect the router to a thin Ethernet cable, connect a T-connector to the  
BNC connector located on the rear panel of the unit.  
Connecting to Twisted-Pair Ethernet  
Before connecting the router to twisted-pair cabling you need an unshielded twisted-  
pair cable that is already connected to your 10BaseT-compatible twisted-pair hub.  
To connect the router to the twisted-pair network, simply plug the twisted-pair cable  
into the RJ-45 connector on the back of the unit.  
Connecting a Line Device to the BR Router  
The BR Router supports high-speed synchronous or asynchronous operation over  
one RS-232 connector.  
The BR Router supports both PPP and Frame Relay link protocols on this WAN  
port.  
Connecting Devices to the RS-232C Port  
This port -- marked WAN -- can be used to connect to synchronous or asynchronous  
line communications devices at rates up to 128Kbps (115.2 Kbps async).  
 
15  
Examples include modems, leased or switched CSU/DSU’s, and ISDN terminal  
adapters.  
You may select either dial-on demand, redial if down (“always up” mode), or leased  
line operation. These ports may also be set to receive ISDN or switched-56  
incoming calls.  
To connect a device, first make sure that both units are powered off. Then, simply  
connect one of the supplied RS-232 data cables (not an auxiliary port cable)  
between the router and the device.  
v Note: The BR Router RS-232 port requires that your line communications device  
be set to supply the RS-232 DCD signal when a connection has been established  
with the remote end.  
v Note: The BR Router includes a special data cable to facilitate connections to  
RS-232 line communications devices. This cable includes support for several  
asynchronous and synchronous control signals. Off-the-shelf Sun or Macintosh-  
type cables do not support these signals.  
Connecting an Out-of-Band Management Console  
If you wish to connect an out-of-band management console, use the supplied  
auxiliary cable and connect to the AUX port on the back of the BR Router. You can  
use a dumb terminal or a computer equipped with VT100 terminal emulation.  
The default baud rate for the AUX port is 9600.  
Powering Up the Router  
Power up all modems, CSU/DSU’s, and TA’s before powering up the router. This  
allows the router to immediately sense the connected device. At power-up, the  
router will take approximately one minute to become visible to RouterView.  
v Note: If you want to use Telnet as a management method, you must configure an  
IP address into the router using an out-of-band console or RouterView before you  
will be able to contact the router.  
 
 
17  
Chapter 4 - RouterView Software  
Installation  
All of the routers in DCB’ multiprotocol family, including all BR Router and RISC  
Router models, can be managed from a single management platform called  
RouterView. Both a Windows and a Macintosh version of RouterView were  
included with your BR Router.  
v Note: Although the installation procedures for the Windows and Macintosh  
versions of RouterView are slightly different, the programs themselves are virtually  
identical. Once you have installed RouterView on the platform of your choice, you  
can find more information on how to use it in the RouterView Reference Guide  
which was included with your router.  
RouterView for Windows  
RouterView for Windows allows you to manage the BR Router from an IBM-  
compatible PC running Windows. The PC can either be configured as an IPX ODI  
client on a Novell NetWare internet, or as an IP WinSock client on an IP internet.  
System Requirements  
In order to successfully run RouterView for Windows, you need:  
IBM PC or compatible w/ 386 or later processor  
Windows 3.1 or Windows for Workgroups installed  
VGA or better monitor  
And either (or both) of:  
Novell IPX client configuration on a NetWare network, using IPXODI.COM  
WinSock client configuration on an IP network  
v Note: The “IPX 101” appendix to the RouterView Reference Guide contains  
some tips on getting Novell’s IPX ODI running on your client machine.  
v Note: To force a Windows machine which has both IPX and IP installed to use  
IP, you must set the desired transport protocol in RouterView’s Administration  
menu Options screen.  
Installing and Running RouterView for Windows  
This version of the RouterView program can be found on a 3.5-inch diskette labeled  
“RouterView - Windows Disk” that was included with your BR Router.  
 
18  
Start Windows. Insert the diskette into your computer’s disk drive. At the  
Windows Program Manager, select “Run” from the File menu and type A:SETUP  
(where A: is the drive containing the RouterView diskette). This will invoke an  
auto-installation program supplied with RouterView.  
The installation program will ask you to select (or create) a directory in which it  
should locate RouterView and its associated files and database subdirectory.  
Once the installation is complete, double click on the RouterView icon to open the  
program. For further information on using RouterView, see the RouterView  
Reference Guide included with your router.  
v Note: RouterView will be able to use the transport protocol (IP or IPX) you have  
selected to access DCB routers anywhere on your internetwork. This means you  
can use the IP transport option to manage routers across the global Internet  
network if you are connected to it.  
v Note: For an up-to-date description of the changes (if any) made to Windows  
system files by the installation program, see the README.TXT file located in the  
RouterView installation directory.  
RouterView for Macintosh  
RouterView for Macintosh allows you to manage the BR Router from an Apple  
Macintosh or compatible computer. RouterView for Macintosh uses the AppleTalk  
protocol to communicate with the router.  
System Requirements  
A Macintosh version of RouterView was included with your router. You can run  
RouterView from any Macintosh on your network that meets the following technical  
specifications:  
Macintosh with 68030 or later processor (including PowerPC)  
System 7.0 or later.  
v Note: Although older Macintoshes such as SE/30’s and IIsi’s will run  
RouterView adequately for infrequent use, a newer/faster machine is preferable for  
larger networks where RouterView will be used more often.  
Installing and Running RouterView for Macintosh  
To install RouterView for Macintosh, simply insert the RouterView diskette into the  
floppy drive of your Macintosh. Then double click on the self extracting archive  
(.sea) icon. You will be asked where you would like to locate your copy of the  
RouterView program and data files.  
 
19  
Double-click on the RouterView icon and the program will start up and ask you to  
select/create a location for its database. Once the database has been created, this  
message will not reappear when you run RouterView.  
For further information on using RouterView, see the RouterView Reference Guide  
included with your router.  
 
 
21  
Chapter 5 - Setting Up Command  
Line Management  
The command-line interface allows you to configure and monitor the router in-band  
via Telnet or out-of-band with a terminal connected to the BR Router’s AUX port.  
Telnet is a remote terminal communications protocol based on TCP/IP. With  
Telnet you can log into and manage the router from anywhere on your IP  
internetwork, even across the global Internet if you choose. To do this, you must  
run Telnet client software on your local computer, which will communicate with the  
Telnet server built into the router.  
In order to be able to access the command-line interface via Telnet, you must first  
set some IP parameters in the router. You can do this through the AUX port using  
a terminal or a PC with terminal emulation software, or with RouterView if you  
prefer.  
After the IP parameters are set, you can complete the configuration in-band with  
Telnet.  
Out-of-Band Command-Line Management  
Set a terminal or a PC to a baud rate of 9600, and connect it to the router’s AUX  
port using the auxiliary cable which was supplied with the router. Press the  
<Return> key three or four times.  
Enter the default password letmein at the password prompt. The command line  
interface prompt will appear on the screen.  
For further information on using the command line interface, see the Command  
Line Reference Guide that was supplied with your router.  
Setting Up Telnet Operation  
Before being able to access the command line interface via Telnet, you will need to  
complete basic IP configuration for the port which you will connect through.  
This can be done using the set ip commands from a console. For more information  
on these commands, see the Command Line Reference Guide which was supplied  
with your router.  
The required parameters for Telnet operation are the IP address, IP subnet mask,  
and IP broadcast address. To change the configuration parameters in the BR  
Router, you will have to enter a requested password. The default password is  
letmein.  
 
22  
After you have set these basic IP parameters, you can use Telnet to access the router  
from any node on your IP internetwork, so long as communications occur through a  
configured port. Invoke the Telnet client on your local computer with the IP  
address of the router you wish to manage.  
v Note: Proper syntax is vital to effective operation of the command line. Case is  
not significant – you may enter commands in upper case, lower case, or a  
combination of the two.  
 
23  
Chapter 6 - Quickstart Instructions  
This Quickstart section briefly discusses the major parameters that must be set in  
order to use the router.  
There are a number of parameter settings which are optional, in the sense that they  
are not required for all installations. These settings are not covered in this section.  
Whenever you make changes to a router’s configuration with RouterView, you must  
save them to the router’s Flash ROM with the Download to Router selection in the  
Configuration menu. In the following section, RV = RouterView.  
Whenever you make changes to a router’s configuration with the command line (via  
AUX port or Telnet), you must save them to the router’s Flash ROM with the  
save(misc) command. In the following section, CL = Command Line.  
v Note: The BR Router requires different operating software depending on  
whether you wish it to operate in PPP or Frame Relay mode. Both types of  
software were supplied with the router. See the PPP and Frame Relay sections  
later in this section for more information.  
v Note: Considerably more information on the meaning of the router’s parameters  
is provided in the RouterView Reference Guide and the Command Line Reference  
Guide. You should use this list as a starting point to look up more specific  
information in the other documents. If you need more general information on the  
protocols, see the Appendices in the RouterView Reference Guide.  
v Note: If you are using the BR Router to connect to an Internet Service Provider  
(ISP), you will receive your configuration parameters from the technical staff of the  
ISP. These parameters must include all IP addresses, WAN settings, and any  
applicable authorization routines. If you obtained your BR Router directly from an  
ISP, it may be pre-configured for your site.  
Please check with your ISP before configuring or changing the configuration of  
your BR Router.  
Ethernet Port Configuration  
Ethernet ports are considerably easier to set up than wide area ports since there are  
no choices that need to be made regarding line communications devices and their  
parameters. We recommend that you begin by configuring any Ethernet port  
parameters before proceeding to configure WAN port parameters.  
 
24  
IP Protocol  
Required for IP  
These parameters set the basic address characteristics of the port. They provide  
enough information for another IP node to find the port (such as a Telnet client),  
but not enough information for routing to take place.  
IP Address  
IP Subnet Mask  
IP Broadcast Address  
RV: Use the Ethernet/IP screen to set these parameters.  
CL: Use the interface(misc) and ip(set) commands.  
Suggested for IP  
These parameters help supply information about the segment that the port is  
connected to. With this information, routing can take place.  
IP RIP (Routing Information Protocol)  
and/or  
IP Static Routes  
RV: Use the Ethernet/IP screen to set RIP, and the IP Static Routing Window  
(All/IP) to set static routes.  
CL: Use interface(misc) and ip flags(set) to set RIP, and ip route(add) to add  
static routes.  
IPX Protocol  
Required for IPX  
There are generally no required changes from the shipping Ethernet configuration  
for IPX. The Ethernet port will autoconfigure to use the two most common IPX  
frame types, and will autoadapt to conditions on the Ethernet.  
Suggested for IPX  
You may want to set your own network numbers, rather than using the  
autoconfigured values. You may also want to turn off unused frame types.  
RV: Use the Ethernet/IPX screen.  
CL: Use interface(misc) and ipx(set).  
 
25  
AppleTalk Protocol  
Required for AppleTalk  
There are generally no required changes from the shipping Ethernet configuration  
for AppleTalk. The Ethernet port will autoconfigure to use AppleTalk Phase II, and  
will autoadapt to conditions on the Ethernet.  
Suggested for AppleTalk  
You may want to set your own network numbers, rather than using the  
autoconfigured values. You may also want to use more meaningful zone names.  
RV: Use the Ethernet/AppleTalk screen.  
CL: Use interface(misc) and appletalk(set).  
DECnet Protocol  
Required for DECnet  
The router’s shipping configuration does not have DECnet turned on. You must  
turn it on and set several DECnet parameters.  
Turn DECnet on  
Set DECnet area  
Set DECnet node  
RV: Use the Main DECnet screen (All/DECnet).  
CL: Use decnet(set).  
Suggested for DECnet  
Setting the parameters above should be adequate for most installations.  
WAN Port PPP Configuration  
This section covers the settings and software download required for PPP (point-to-  
point) protocol operation of the BR Router WAN port.  
The RS-232 WAN port on a BR Router can be run synchronously or  
asynchronously, at rates up to 128Kbps (sync), or 115.2Kbps (async).  
 
26  
Operating Software  
Required for PPP  
PPP operation requires the correct operating software download in the BR Router’s  
Flash ROM. You can identify the correct software version by the “P” in the fourth  
character of the filename (i.e. M10P210.DLD).  
RV: Use the Download Software selection under the Administration menu.  
CL: Software download support is not available directly from the command line.  
However, the BR Router does support the TFTP protocol for software downloads.  
See tftp(misc).  
v Note: The BR Router is shipped with PPP as the factory default operating  
software download. Unless you previously downloaded a Frame Relay software  
load, you shouldn’t need to download different operating software.  
IP Protocol  
Required for IP  
WAN ports which are set for PPP operation do not generally use an IP address.  
They are set to act as an “unnumbered interface.” In this mode of operation, there  
are no required settings.  
Suggested for IP  
These parameters help supply information about the segment that the port is  
connected to. With this information, routing can take place.  
IP RIP (Routing Information Protocol)  
and/or  
IP Static Routes  
IP Default Router  
v Note: If you set RIP to on for a dial-on-demand link, you must also set the update  
method to triggered to avoid the link being brought up by transmission of RIP  
information.  
RV: Use the WAN/IP screen to set RIP and the update method, and the IP Static  
Routing Window (All/IP) to set static routes and a default router.  
CL: Use interface(misc) and then ip flags(set) to set RIP, and ip wan(set) to set  
the update method, and ip route(add) to add static routes. User interface(misc)  
and ip(set) to set the default router.  
 
27  
IPX Protocol  
Required for IPX  
WAN ports which are set for PPP operation do not generally use an IPX address.  
They are set to act as an “unnumbered interface.” In this mode of operation, there  
are no required settings.  
Suggested for IPX  
If you plan to use dial-on-demand for this link, you should set the update method (to  
triggered) to avoid the link being brought up by transmission of IPX RIP  
information.  
Update Method  
RV: Use the WAN/IPX screen.  
CL: Use interface(misc) and then ipx wan(set).  
AppleTalk Protocol  
Required for AppleTalk  
WAN ports which are set for PPP operation do not generally use an AppleTalk  
address. They are set to act as an “unnumbered interface.” In this mode of  
operation, there are no required settings.  
Suggested for AppleTalk  
If you plan to use dial-on-demand for this link, you should set the update method (to  
triggered) to avoid the link being brought up by transmission of AppleTalk RTMP  
information.  
Update Method  
RV: Use the WAN/AppleTalk screen.  
CL: Use interface(misc) and then appletalk wan(set).  
DECnet Protocol  
Required for DECnet  
WAN ports which are set for PPP dial-on-demand operation should have their  
DECnet hello timers and DECnet routing timers set for a fairly long period, since  
the link will be brought up when this information is transmitted.  
Hello timer  
Routing timer  
 
28  
RV: Use the WAN/DECnet screen.  
CL: Use interface(misc) and then decnet wan(set).  
Link Configuration

Outgoing dial-on--demand requires some additional information.  
Set dialing method  
Create dial-out script  
Set dial-out script to be used  
RV: Use the WAN/Link window to set the dialing method and to select a chat  
script (once you have created one). Use the Chat Script Editor window (All/Link)  
to create your chat script.  
CL: Use interface(misc) and then wan connect(set) to set the dialing method and  
to select a chat script (once you have created one). Use the chat(edit) command to  
create a chat script.  
 
29  
Physical Comm Settings  
You may need to set the baud rate, sync/async operation, and other physical  
communications parameters for the WAN port. These parameters will depend on  
the line communications device you are using.  
RV: Use the WAN/General window.  
CL: Use interface(misc) and then wan serial(set).  
WAN Port Frame Relay Configuration  
This section covers the settings required for Frame Relay operation of the BR  
Router WAN port.  
The RS-232 WAN port on a BR Router can be run synchronously or  
asynchronously, at rates up to 128Kbps (sync), or 115.2Kbps (async).  
Operating Software  
Required for Frame Relay  
Frame Relay operation requires the correct operating software download in the BR  
Router’s Flash ROM. You can identify the correct software version by the “F” in  
the fourth character of the filename (i.e. M10F210.DLD).  
RV: Use the Download Software selection under the Administration menu.  
CL: Software download support is not available directly from the command line.  
However, the BR Router does support the TFTP protocol for software downloads.  
See tftp(misc).  
v Note: The BR Router is shipped with PPP as the factory default operating  
software download. You must download Frame Relay operating software into the  
router in order to run in Frame Relay mode.  
IP Protocol  
Required for IP  
Frame Relay operation requires that the WAN port is set to be a “numbered  
interface.” This means that the port (and thus the Frame Relay network) must have  
an IP address, etc.  
IP numbered interface  
IP Address  
 
30  
IP Subnet mask  
IP Broadcast Address  
RV: Use the WAN/IP screen to set these parameters.  
CL: Use the interface(misc) and ip(set) commands.  
Suggested for IP  
These parameters help supply information about the segment that the port is  
connected to. With this information, routing can take place.  
IP RIP (Routing Information Protocol)  
and/or  
IP Static Routes  
IP Default Router  
RV: Use the WAN/IP screen to set RIP, and the IP Static Routing Window (All/IP)  
to set static routes and a default router.  
CL: Use interface(misc) and then ip flags(set) to set RIP, and ip route(add) to add  
static routes. User interface(misc) and ip(set) to set the default router.  
IPX Protocol  
Required for IPX  
Frame Relay operation requires that the WAN port is set to be a “numbered  
interface.” This means that the port (and thus the Frame Relay network) must have  
an IPX network number.  
IPX numbered interface  
IPX Network Number  
RV: Use the WAN/IPX screen.  
CL: Use interface(misc) and then ipx(set).  
Suggested for IPX  
The settings above are all that is generally required for IPX operation over Frame  
Relay.  
 
31  
AppleTalk Protocol  
Required for AppleTalk  
Frame Relay operation requires that the WAN port is set to be a “numbered  
interface.” This means that the port (and thus the Frame Relay network) must have  
an AppleTalk network number and the port must have an AppleTalk node number.  
AppleTalk numbered interface  
AppleTalk Network Number  
AppleTalk Node Number  
RV: Use the WAN/AppleTalk screen.  
CL: Use interface(misc) and then appletalk(set).  
Suggested for AppleTalk  
The settings above are all that is generally required for AppleTalk operation over  
Frame Relay.  
DECnet Protocol  
Required for DECnet  
Once DECnet has been turned on (a global setting discussed in the Ethernet section  
above), no additional settings are generally required for DECnet operation over  
Frame Relay.  
Link Configuration  
Frame Relay is presently supported in the BR Router only via dedicated line  
operation.  
Set Dedicated connection  
Set Frame Relay connection  
RV: Use the WAN/Link screen.  
CL: Use interface(misc) and then wan mode(set).  
Suggested for Dedicated/Leased Line Operation  
Dedicated line operation generally does not require additional parameters for  
operation.  
 
32  
Frame Relay DLCI Mappings  
If you are connecting to another DCB router, this information is not required. DCB  
uses IARP (Inverse Address Resolution Protocol) to dynamically generate this  
information. To connect to other vendors’ routers which do not support IARP, or  
do not have it turned on, you must provide DLCI to protocol mapping information.  
RV: Use the DLCI Mapping Database window.  
CL: Use interface(misc) and then frelay(set).  
Physical Comm Settings  
You may need to set the baud rate, sync/async operation, and other physical  
communications parameters for the WAN port. These parameters will depend on  
the line communications device you are using.  
RV: Use the WAN/General window.  
CL: Use interface(misc) and then wan serial(set).

Appendix C - Light Patterns and  
Test Switch Settings  
BR Router Light Patterns  
The BR Router uses a number of light patterns on its front LED bar to indicate  
operating conditions.  
2 & 9 on steady: Router is powered on.  
v Note: Lights 1 and 10 are directly connected to the router’s 10BaseT interface  
and indicate 10BaseT link (1) and 10BaseT polarity (10).  
Traffic Indicators  
Scan from 2 to 5: Ethernet receive packet  
Scan from 5 to 2: Ethernet transmit packet  
Scan from 6 to 9: WAN receive packet  
Scan from 9 to 6: WAN transmit packet  
Other Indicators  
5 & 6 on steady: Flash ROM checksum in progress  
5 & 6 flashing: Router stacks starting up  
2,3,4 & 7,8,9 flashing: Running from ROM  
2,3,4 & 7,8,9 on solid: Erasing Flash ROM  
2,3 & 8,9 on solid: Writing Flash ROM  
4 & 7 on solid: Compressing Flash ROM image  
Level 1 Panic Indicators  
Any continuous flashing pattern not noted above may be caused by a software  
“panic.” This is a sign that a condition has been detected that the software does not  
know how to deal with: either an unusual network condition, or a hardware failure.  
v Note: Level 1 panics are very unusual. These are not the same as Level 2  
panics, which cause the router to save the reason for the panic and restart. The  
existence of a Level 2 panic signature will be reported by RouterView or the  
command line.
