USING THE BRIDGE/ROUTER IN
YOUR NETWORK
2
This chapter gives an overview of SuperStack II NETBuilder SI
bridge/routers and describes how they fit in your network. It also
describes the software features of the bridge/router.
Overview
SuperStack II bridge/routers maintain connectivity among small, midsize,
and large branch offices and the corporate LAN.
SuperStack II NETBuilder SI bridge/routers come with two Ethernet ports,
two or four serial ports, and one of the following WAN ports: ISDN S/T
(models 43x and model 53x), ISDN U (models 44x and 54x), 56/64 Kbps
Carrier Service Unit/Data Service Unit (CSU/DSU) (models 45x and 55x), or
T1/FT1 Telco port (models 46x and 56x). You can change any model 4xx
bridge/router to another model 4xx, or any model 5xx to another model
5xx, by installing, removing, or replacing an interface module.
All models can be upgraded to any software package. All models have
dual-image software support for upgrading and backup.

CHAPTER 2: USING THE BRIDGE/ROUTER IN YOUR NETWORK
Using WAN and
Serial Ports
SuperStack II NETBuilder SI bridge/routers come with two or four serial
ports and one of the following WAN ports: a built-in ISDN S/T terminal
adapter (TA) (models 43x and 53x), a built-in ISDN U TA (models 44x and
54x), a built-in 56/64 Kbps CSU/DSU (models 45x and 55x) or a built-in
T1/FT1 Telco port (models 46x and 56x).
ISDN Port (Model 43x, The ISDN port provides a basic rate interface (BRI). The BRI delivers two
53x, 44x and 54x) bearer (B) channels and one delta (D) channel. Each B channel can
transmit up to 64 kilobits per second (kbps); the D channel transmits
information about the call to computers at the switching system at a rate
rate of 128 kbps, or use each 64 kbps B channel separately.
Some ISDN lines support up to 56 Kbps per B channel. For more
information, contact your ISDN service provider.
Order ISDN lines from the phone company. See Appendix E for more
information about ordering ISDN lines.
Installations in Hong Kong should be configured to originate and receive
ISDN calls at 64 Kbps. Due to the variety of ISDN switches in the Hong
Kong Telcom network, the SuperStack II NETBuilder SI bridge/router does
not handle rate adapted ISDN calls at 56 Kbps properly.
56/64K CSU/DSU Port A CSU/DSU is equivalent to a modem for a digital line. The 56/64K
(Model 45x CSU/DSU port connects directly to a Digital Data Service (DDS).
and 55x)
Order DDS lines from the phone company. Contact your phone company
for more information about DDS lines and the services available for them.
T1/FT1 CSU/DSU Port A CSU/DSU is equivalent to a modem for a digital line. The T1/FT1
(Model 46x and 56x) CSU/DSU port connects directly to a T1 line or a fractional T1 line.
Fractional T1 consists of 24 channels (DS0s) at 64 Kbps each, so you can
connect to one or more DS0s with the T1/FT1 port.
Order T1 lines from the phone company. Contact your phone company
for more information about T1 lines and the services available for them.

Telco Services
25
Serial Ports The serial ports are multifunction Flex-WAN ports that provide connection
to industry-standard V.35, RS-232, RS-449, RS-530, or X.21 Data
Communications Equipment (DCE) or Data Terminal Equipment (DTE)
serial devices. You can buy Flex-WAN cables separately from 3Com. See
Appendix D for more information about Flex-WAN cables.
If you are using two SuperStack II NETBuilder SI bridge/routers connected
directly to each other by the serial ports (back-to-back), the
bridge/routers do not meet radiated emissions specifications.
For boundary routers, only one serial or WAN port can be active. The
remaining ports are used for back-up only.
Telco Services
To create a WAN, you must buy lines and services from a
telecommunications company (Telco). Services include dial-up lines,
leased lines, and packet-switched services.
Dial-up lines, like ISDN, allow you to dial your destination when necessary
and hang up when you no longer need the connection. A leased line is
always available between two locations. Dial-up and leased lines both use
Packet-switched services, like Frame Relay, use a combination of leased or
dial-up lines with Telco-owned switching, which frees you from the cost
of owning the line the entire length.
Table 4 describes dial-up and leased line services available for the WAN
and serial ports. Table 5 describes packet-switched services.

Using PPP on Dial-Up and Leased Lines
All dial-up and leased lines use PPP. If you want to use multiple lines or
channels to connect to the same destination, you can use Multilink PPP.
Multilink PPP is especially useful for ISDN, as described in the following
section.
ISDN ISDN consists of two bearer (B) channels and one delta (D)
channel. Each B channel can transmit up to 64 Kbps; the D channel
transmits signaling information about the call to computers at the
switching system at a rate of 16 Kbps.
With Multilink PPP, you can use both B channels together for a combined
data rate of 128 Kbps. With PPP, you can use each 64 Kbps B channel
separately.
Some ISDN lines support up to 56 Kbps per B channel. For more
information, contact your ISDN service provider.
Using Packet-Sw itched Netw ork Services
You can use packet-switched services with your bridge/router instead of
dial-up or leased lines to take advantage of high performance for a
reasonable price. This section describes X.25 and Frame Relay.
X.25 An X.25 packet-switched network is defined by the International
Telecommunications Union (ITU) Recommendation X.25, a global
standard that began development in the 1970s. The recommendation

defines a point-to-point interaction between DTEs and DCEs. In simpler
terms, when it is time to transmit data, a terminal connects to a modem
or packet switch, which then connects to packet switching exchanges
(PSEs) and other DCEs to transmit the data to its final destination at
another terminal. The links by which data is transmitted are called virtual
circuits. Virtual circuits allow data transfers between two points on the
network through any number of nodes in the network.
Frame Relay Frame Relay provides a packet-switched network that
transfers data between DTEs, which can be routers, bridges, and host
computers, by creating virtual circuits and using DCEs to transfer the data
to its destination.
Frame Relay differs from X.25 (which was developed to work over
voice-grade telephone lines) because it was designed to make use of
today’s higher speed digital lines. Frame Relay has also been designed to
work within complex internetworking environments with extensions
referred to as the local management interface (LMI).
LMI provides information about all devices that are accessible on the
Frame Relay network by listing all data link connection identifiers (DLCIs)
connecting the local system with the remote ones. The LMI improves
keepalive packets that contain status information.
IBM Legacy Netw orks Each serial port can be attached directly with a Flex-WAN cable to IBM
legacy equipment like mainframes and automatic teller machines. See
Table 4 for supported IBM protocols.

CHAPTER 3: INSTALLING THE HARDWARE
Cabling the
Connectors
The SuperStack II NETBuilder SI bridge/router has two Ethernet ports,
either two or four serial ports depending on the model, and one of the
following WAN ports: ISDN S/T (43x and 53x), ISDN U (44x and 54x),
56/64 Kbps CSU/DSU (45x and 55x), or T1/FT1 CSU/DSU (46x and 56x).
This section describes how to cable each port on your bridge/router.
Boundary router models can use only one Ethernet port and only one
serial or WAN port can be active at a time. You can cable the remaining
serial or WAN ports to be used as back-up. If you upgrade to full router
software, the second Ethernet port and back-up serial ports will be
functional.
Cabling the LAN You can cable one or two Ethernet connectors using either 10BASE-T or
Connectors 100BASE-TX cabling. If you have a boundary router, cable only the L1
connector.

Power cable
For full power supply redundancy, attach one end of the RPS cable to the
rear panel on the bridge/router and the other end to the RPS. Then attach
one end of the power cord to the rear panel on the bridge/router and the
other end to a power outlet.
In this configuration, the internal supply provides power. If the internal
supply fails or is switched off, or if there is a power failure, the RPS is
activated and the bridge/router reboots.
To reset a bridge/router in this configuration, turn the power off, wait 5
seconds and turn it back on. The bridge/router switches to the RPS, then
switches back to the internal supply to reboot.
CAUTION: For system susceptibility protection, always leave the AC cord
attached to the bridge/router and to a power outlet.
Internal power supply failure is rare. If it occurs, the power switch on your
bridge/router will not operate. To reboot, unplug the RPS cable and then
plug it back in. Replace your bridge/router with another bridge/router
that has a functioning internal power supply as soon as possible. Contact
your 3Com representative to replace your bridge/router.

Changing the Root Password
59
Changing the Root
Passw ord
The default root password is a null string, which is generated by pressing
the Return key.
You should specify a new password immediately after you log on for the
first time. Changing the root password prevents unauthorized users from
accessing and executing software commands and parameters.
The root user has two privilege levels and passwords: Network Manager
and User. The User privilege enables only a subset of software commands.
You should assign passwords for both levels. If you log in as root and
enter the Network Manager password, you have Network Manager
privilege. If you log in as root with the User password, you have User
privilege.
You might log on with the User password if you do not want to create
user accounts. If you want to change the privilege level without logging
off, use:
SET -SYS PRIvilege = User | NetMgr
The following guidelines exist when changing a password:
■
You must be logged on as root with Network Manager privilege.
■
You must change the Network Manager password before you change
the User password.
■
You must clear the User password before you clear the Network
Manager password.
To change the password for both privilege levels, enter:
SysPassWord
A menu is displayed.
Follow the menu to set the Network Manager password and then the
User password.
CAUTION: You must set both the Network Manager and the User
password. If the User password is not set, any unauthorized user can
logon with User level privilege.

Setting System
Information
You should set the system name to interoperate with other NETBuilder
bridge/routers. You can also set the location and contact so that other
system administrators can contact you for information.
To set the system name, location, and contact, follow these steps:
1 (Required) Assign a name to the bridge/router using:
SETDefault -SYS SysNAMe = “<string>”
For example, to set the system name to Engineering.SanJose, enter:
SETDefault -SYS SysNAMe = “Engineering.SanJose”
2 (Optional) Specify the system location using:
SETDefault -SYS SysLOCation = “<string>”
For example, to set the system location to SecondFloor.Lab, enter:
SETDefault -SYS SysLOCation = “SecondFloor.Lab”
3 (Optional) Identify the contact person managing the bridge/router using:
SETDefault -SYS SysCONtact = “<string>”
For example, to identify John Smith as the system contact and
(408)555-1111 as the phone number at which to reach him, enter:
SETDefault -SYS SysCONtact = “John Smith (408) 555-1111”
If the system contact is specified, users can obtain this information using
the SHow -SYS SysCONtact command.

BASIC CONFIGURATION OF PORTS

This chapter contains conceptual information about ports and paths and
contains basic configuation procedures for each of the interfaces on your
SuperStack II NETBuilder SI bridge/router.
Paths, Ports, and
Virtual Ports
and understanding the concept of ports and paths is important. This
section defines ports and paths and explains how they are numbered.
The fundamental difference between paths and ports is that the path is
the physical interface and the port is the logical interface in the software
that is mapped to the physical path. Figure 6 illustrates the relationship
between paths and ports.

Paths and Ports A path is the physical interface that connects a bridge/router to a physical
network medium such as Ethernet or a serial line. Each path is associated
with a connector. If you have a built-in ISDN connector, each B channel is
assigned a separate path, for instance 3.1 and 3.2.

CHAPTER 6: BASIC CONFIGURATION OF PORTS AND PATHS
A port is the logical interface used by the software to represent a
connection to a network.
traffic received on physical path 1 is treated by the software as arriving on
logical port 1, and all traffic that the software transmits through logical
port 1 passes through physical path 1.
A path that is assigned to one port is a static path. Some configurations
require the options described in Table 11.
Table 11 Port and Path Options
Option
Description
Multiple paths per
port: dynamic paths
A dynamic path is not assigned to any one port, but is
available in a dial pool. A dial pool enables you to dial
multiple destinations, use bandwidth-on-demand, and
failover to another line without having to reserve specific
paths for a port. A port may require multiple paths from the
dial pool.
Multiple paths per
port: static paths
Use multiple static paths on the same port:
■
To use both B channels together on a built-in ISDN
connector using Multilink PPP.
■
■
To reserve a path for disaster recovery.
To use a path for dial-on-demand, failover, or
bandwidth-on-demand.
Multiple ports per
path: virtual ports
A virtual port can be assigned to a path or to a SysCallerID
that represents a remote site.
Dynamic Paths Ports running PPP can use a dial pool of available paths. A dial pool
and failover to another line without having to reserve specific paths for a
port. A dial pool is created when you unbind a path from its port by
using:
SETDefault !<path> -PATH DialCONTrol = DYNamic

per Port
To use both B channels together on a built-in ISDN connector, to reserve a
path for disaster recovery, or to use another path for dial-on-demand,
failover, or bandwidth-on-demand, you can assign both paths to one port
ADD !<port> -PORT PAths <path> [,<path>...]
You may want to use static ports instead of a dial pool if you are only
dialing one destination and do not need the versatility of a dial pool.
See “Configuring Bandwidth Management for PPP” on page 89 for more
information about bandwidth management features such as
dial-on-demand.
Virtual Ports To configure multiple ports over one path, you create virtual ports. A
virtual port can be assigned to a static path, or for PPP, it can be assigned
to the SysCallerID of a remote site. SysCallerID virtual ports use paths in a
dial pool and are not associated to any one path.
A virtual port functions the same way as a nonvirtual port does, that is, as
a logical interface that represents a connection to a network.
connect to two separate boundary routers over the same ISDN port at
different times, you can create a virtual port for each boundary router.
The virtual ports would have all the connection information for each
boundary router.
Table 12 provides information on topologies that require virtual ports and
the node on which the virtual ports should be created.

CHAPTER 6: BASIC CONFIGURATION OF PORTS AND PATHS
Virtual Ports over Frame Relay and X.25
Frame Relay and X.25 are peer-to-peer protocols that connect two nodes
on the network. Boundary Routing and bridging, Internet Protocol-Open
Shortest Path First (IP-OSPF), DECnet IV, VINES, and Xerox Network
Systems (XNS) require virtual ports because they do not provide a method
for dealing with Frame Relay or X.25 topologies where bridge/routers are
not directly connected to all others (full mesh). With Boundary Routing
system architecture, when you create a virtual port over a particular path,
each remote network attached to the Frame Relay or X.25 cloud is
treated as a separate network.
Internet Protocol-Routing Information Protocol (IP-RIP), Internetwork
Packet Exchange (IPX), DECnet V, and AppleTalk can operate over partially
meshed or nonmeshed Frame Relay or X.25 topologies without the use of
virtual ports.
The next-hop split horizon feature in IP-RIP, IPX, and AppleTalk RTMP
allows communication between bridge/routers that are not directly
connected to one another. To configure next-hop split horizon for these
routing protocols, you must have a list of neighbors, which can be
dynamically generated or manually configured in IP-RIP. Next-hop split
horizon is configured by adding static mappings to the address mapping
table.
You can configure dynamic neighbor learning for IPX using the CONTrol
parameter in the NRIP, SAP, and NLSP Services.
Although it is not necessary to define virtual ports on IP-RIP, IPX, or
AppleTalk routers in partially meshed or nonmeshed Frame Relay or X.25
topologies, virtual ports do provide the following additional benefits:
■
A virtual port can be defined for each configured neighbor, which
allows you to set up such features as filters and routing policies on a
per-neighbor basis.
■
Virtual ports provide easier control over your network, turning your
network into several point-to-point lines.
If you want your SuperStack II bridge/router to act as an Open System
Interconnection (OSI) router in a Frame Relay or X.25 topology, you do
not need to create virtual ports.

Virtual Ports over PPP
PPP virtual ports differ from Frame Relay and X.25 virtual ports in the
following ways:
■
A PPP virtual port can potentially use any path in the dial pool.
Frame Relay and X.25 virtual ports are always associated with a
particular path.
■
PPP virtual ports operate independently and do not have a parent
port. No parent port exists because the path was unbound from its
port and placed into the dynamic dial path pool.
Frame Relay and X.25 virtual ports inherit the attributes of the path
over which they are defined.
■
PPP virtual ports can be used with dial-up related parameters.
Frame Relay and X.25 virtual ports cannot be used with dial-up related
parameters.
You can use virtual ports in a PPP environment to provide dial pooling at
the central site router. With dial pooling, a set of dynamic paths is

68
CHAPTER 6: BASIC CONFIGURATION OF PORTS AND PATHS
unbound from their default ports and waits in the dial pool for an
incoming call. When a call is received, the dynamic path that answers is
assigned to a virtual port, which is standing by with the appropriate
configuration information for the calling network. Because not all sites
using a dial pool call the central site at the same time, it is possible to
share a small group of paths with a larger group of sites. Each site that
can potentially call into the dial pool has its own virtual port defined, so
there are usually more virtual ports configured for the dial pool than
dynamic paths assigned to it.
Parent Ports for Frame Relay and X.25
When you configure an X.25, or Frame Relay virtual port, it inherits the
attributes of the path over which it is defined. It also inherits some of the
attributes of its parent port.
For PPP dial virtual ports, no parent port exists because the path was
unbound from its port and placed into the dynamic dial path pool.
Unlike Frame Relay and X.25 virtual ports, which are always associated
with a particular path, PPP virtual ports can potentially use any path in the
dynamic dial path pool. PPP virtual ports also can be used with dial-up
related parameters.
For example, if you create a Frame Relay or X.25 virtual port
associated with a wide area port, the virtual port inherits port attributes
from the following sources:
■
Default and configured values of PORT Service parameters specified
for a wide area port, with the exception PORT Service parameters that
are not related to X.25 and Frame Relay virtual ports.
■
Default and configured values of parameters from all other services
specified for a wide area port.
To configure a virtual port, you must specify the virtual port and not the
parent port. For example, if you are using the SETDefault !<port> -BCN
CONTrol = Enabled syntax, you must specify the virtual port number
instead of the parent port number for <port>. For complete information
on the numbering convention of virtual ports, see “Path and Port
Numbering” on page 69.

If you have only one local telephone number, enter the same number for
both channels.
2 If you are planning to use channel B2 as a separate line, and your
telecommunications carrier provided only one telephone number for all

The bridge/router automatically detects the switch type and SPIDs of the
ISDN line and disables the parameter. If you change your local telephone
number, you will have to re-enable the SpidWIZard parameter.
Do not disable the SpidWIZard parameter while it is detecting the switch
type and SPIDs. If you do, you will have to restart the bridge/router.
If the SpidWIZard parameter does not detect the switch type and SPIDs
correctly, complete the procedure in the next section.

Permissive. The answering device must be capable of generating the
2.1 KHz tone needed to disable any echo cancellers on the line. Consult
with the owner of the destination equipment to see whether it has this
capability.
To configure this feature, you must define the DialNoList entry with a type
of BriV, by using:
ADD !<port> -POrt DialNoList "<phone number>" Type=BriV
The Baud specifier in the ADD command, although not disallowed, is
ignored if present. Data sent over the B channel will only be sent at 56
Kbps.

Enabling Digi64S2 There are two types of ISDN leased lines in Germany: Digi64S and
Digi64S2. Digi64S can run only on the B1 channel, but Digi64S2 can run
on the B1 and B2 channels.
To enable the Digi64S2 feature, follow these steps:
1 Set the LineType parameter to Digi64S2 by entering:
SETDefault !2.1 -PAth LineType = Digi64S2 (abbreviated d64s2)
SETDefault !2.2 -PAth LineType = Digi64S2
2 Toggle the respective paths by entering:
SETDefault !2.1 -PAth cont=e
SETDefault !2.2 -PAth cont=e
Path 2.1 is mapped to the B1 channel and path 2.2 is mapped to the B2
channel. This mapping is not interchangeable.
If one of the paths is set to Digi64S2, the path in the same connector line
is also set to Digi64S2. Mixtures of line types within a single connector
are not supported.

Scenario 1: Using Each B Channel Separately
If you need to connect to two separate locations at 64 Kbps, use each B
channel separately. Each B channel can connect to only one location,
though both locations can be separate ports on the same bridge/router.
Each B channel connects
separately to one destination.

Scenario 2: Using Both B Channels Together
If you need to connect to one location at 128 Kbps, use both B channels
together.
The destination must be running Multilink PPP, either on the NETBuilder
bridge/router with a built-in ISDN port or on the TA.
Both B channels connect

for your destination, enter the number twice with a letter after the
second entry. If you have two numbers, enter each phone number:
ADD !3 -PORT DialNoList "1-408-555-1000" Baud = 64 Type = Bri

Scenario 3: Connecting to Multiple Destinations
If you need to connect to multiple destinations using one or both B
channels, use a dial pool that contains all ISDN paths. The following
scenarios show how a SuperStack II bridge/router using a dial pool can
connect to three different locations.

To use both B channels together, the destination must be running
Multilink PPP, either on the NETBuilder bridge/router with a built-in
ISDN port or on the TA.
If you use built-in ISDN ports and ISDN TAs in the same dial pool, and
you are using Multilink PPP on the SuperStack II bridge/router, you can
use the TA at only 56 or 64 Kbps.
When using a dial pool, you cannot accept phone calls from other
vendors’ bridge/routers.

CHAPTER 7: ADVANCED CONFIGURATION OF PORTS AND PATHS
Enabling Dial-On-Demand
Dial-on-demand automatically dials the destination bridge/router when
network traffic is present and hangs up when the network is idle.
Dial-on-demand also provides failover support. If the primary line goes
down, the bridge/router will failover to another available dial-up line,
either from a dial pool or from another path assigned to the same port.
The bridge/router may use multiple lines to acheive the normal
bandwidth.
To use failover or to use multiple lines to acheive normal bandwidth, you
must have multiple phone numbers in the dial number list. The first
number is for the primary line. If the primary line fails or provides less
than normal bandwidth, the port dials the second number in the list, then
the following numbers in succession if required. The dial number list
allows you to use a different path for each phone number by specifying
For example, the first number in my dial number list uses a 64 Kbps BRI
line. The second number uses a 28.8 modem. If the ISDN line fails, the
port will dial the 28.8 modem next.
See “Working with Dial Number Lists” on page 113 for more information
about dial number lists.
To enable dial-on-demand, follow these steps:
1 Enable dial-on-demand for a port or virtual port using:
SETDefault !<port> -PORT DialInitState = DialOnDemand
2 Set the amount of time before the dial-up line is disconnected if it is not
in use:
SETDefault !<port> -PORT DialIdleTime = <seconds> (0-3600)
Using Manual Dial
Manual dial is enabled by default. To place a call manually, follow these
steps:
1 If you have previously enabled dial-on-demand, enable manual dial using:
SETDefault !<port> -PORT DialInitState = ManualDial
2 Place the call using:
DIal !<port> [-PORT] [“<dial-string>”]
Download from Www.Somanuals.com. All Manuals Search And Download.
91
If you do not enter a telephone number for dial-string, the software uses
the first number in the dial number list.
The dial string must be a number in the dial number list.
3 Hang up the call using:
HangUp !<port> [-PORT]
Configuring Bandw idth-On-Demand
When the system detects traffic congestion on a port, you can enable
bandwidth-on-demand to automatically activate more lines from a dial
pool or from another path assigned to the same port.
You specify the bandwidth that a port should operate at normally, then
define the maximum amount of bandwidth above this setting that the
port can have.
bandwidth-on-demand, you must have multiple phone numbers in the
dial number list. The first number is for the primary line. If you need more
bandwidth, the port dials the second number in the list, then the
following numbers in succession if required.
See “Working with Dial Number Lists” on page 113 for more information
about dial number lists.
To configure bandwidth-on-demand, follow these steps:
1 Enable bandwidth-on-demand and specify the amount of additional
bandwidth to allocate for a port using:
SETDefault !<port> -PORT BODIncrLimit = <kbps>
The bridge/router allocates additional bandwidth in increments equal to
the Kbps you specify. Maximum total bandwidth equals the
BODIncrLimit plus the normal bandwidth.
2 Specify the conditions that activate bandwidth-on-demand using:
SETDefault !<port> -PORT BODTHreshold = <%>(0–100)
The increase or decrease in bandwidth is based on a percentage of the
outgoing traffic rate. Bandwidth is increased when the outgoing traffic
rate exceeds the percentage of the current port bandwidth. Bandwidth is
decreased when the rate of traffic runs below the specified percentage.
For example, normal available bandwidth is 64 Kbps and you set
BODTHreshold to 50% . To activate another line, traffic would have to
Download from Www.Somanuals.com. All Manuals Search And Download.
92
CHAPTER 7: ADVANCED CONFIGURATION OF PORTS AND PATHS
increase to 32 Kbps (50% of 64 Kbps). After the additional 64 Kbps line
is up, total bandwidth available is 128 Kbps. To activate the next line,
traffic would have to increase to 64 Kbps (50% of 128 Kbps). The same
process happens in reverse to deactivate the additional lines.
3 Specify the amount of time bandwidth management should wait to take
action to activate or deactivate a port using:
SETDefault !<port> -PORT DialSamplPeriod = <seconds>(0–300),
(0–300)
Example To configure a line with a normal bandwidth of 28.8 kbps, enter:
SETDefault !4 -PORT BODIncrLimit = 28.8
SETDefault !4 -PORT BODTHreshold = 50
SETDefault !4 -PORT DialSamplPeriod = 30, 60
Traffic must exceed 14.4 kbps for 30 seconds before an additional dial
path is activated. The additional dial path is deactivated when the rate
of traffic is less than 28.8 kbps for longer than 60 seconds.
Configuring Disaster Recovery
If the primary PPP line fails, the bridge/router can use a reserved dial-up
line as back-up. See Chapter 8 to fine-tune the disaster recovery line for
your routing protocol.
To enable disaster recovery, follow these steps:
1 Enable dial-on-demand.
2 Add the back-up path to the same port as the primary line using:
ADD !<port> -PORT PAths <port> [,<port>...]
3 Enable disaster recovery using:
SETDefault !<port> -PORT DialCONTrol = DisasterRcvry
4 Configure the back-up line for disaster recovery only using:
SETDefault !<path> -PATH DialCONTrol = DisasterRcvry
5 Configure the dial number list for the back-up line using:
ADD !<port> -PORT DialNoList “<phone no>” [Baud = <rate>
(1.2–16000)] [Type = Modem | Bri | Sw56] | [Pos = <number>]

Configuring Frame
Relay
This section describes three Frame Relay scenarios:
■
■
■
Scenario 1: Multiple Destinations, Nonmeshed
Scenario 2: Partially Meshed Topology
Scenario 3: Fully Meshed Topology
To configure a second Frame Relay line for disaster recovery, see Using
Enterprise OS Software.
These scenarios require your Frame Relay switch to support the Local
Management Interface (LMI) Protocol. If your switch does not support
LMI, see Using Enterprise OS Software for configuration procedures.
Obtain DLCIs for each remote site from the Frame Relay service provider.
A DLCI identifies a circuit from the bridge/router to a destination. The
destination uses a different DLCI for the circuit to the main site. Because a
DLCI is known only by one end of the link, DLCIs may not be unique.
In the following example, the DLCI from site A to site C is @100.
Coincidentally, the DLCI from site C to site A is also @100. Although the
numbers are the same, there is no relationship between them. The DLCI
from site A to site B is @90, but the DLCI from site B to site A is @80.

Meshed Topology directly to some destinations but not others. Use virtual ports to pass
traffic from one site to another over the same parent port.
Instead of using virtual ports (if you run out of virtual ports, for example),
you can use the next-hop split horizon feature in the routing protocol.
See Using Enterprise OS Software for more information.
In this scenario, site B is not connected to site C, and site A is not
connected to site D. Create virtual ports on site A so traffic from site B
can pass through site A to get to site C. Create virtual ports on site C so
traffic from site D can pass through site C to get to site A. For

The model 4x7 bridge/router can be used as a central node in a Boundary
Routing environment. SuperStack II NETBuilder SI bridge/routers can be
used as a central node only for Ethernet boundary routers.
The model 5xx bridge/router does not support leaf node Boundary
Routing.
Boundary Routing system architecture treats the remote site as another
central site LAN segment, which allows all routing to occur at the central
site. Boundary routers require very little or no configuration. You must
configure the central site for Boundary Routing by referring to the
following chapters in Using Enterprise OS Software:

Transparent
Bridging
When transparent bridging is enabled, the bridge forwards packets based
on the destination address in the packets it receives. It also learns and
records information about the location and addresses of devices on the
surrounding networks, based on the source address in the received
packets.

Configuring Static Routes
Learning Routes with OSPF
Configuring Route Redundancy
Assigning Addresses Automatically from BOOTP Servers
To fine-tune your IP router, including configuring an Internet firewall or
network address translation, see Using Enterprise OS Software.
To use IP, each device on the network must have a unique IP address. To
route IP, the bridge/router must have an IP addess assigned to each LAN,
WAN, or virtual port.
After assigning IP addresses and enabling IP routing, the bridge/router
must use a routing table to identify other routers on the network to send
data to. You can create the routing table manually by entering the IP
address of each connected router, or you can use a dynamic routing
protocol, such as OSPF, that builds the routing table automatically.

Configuring IP Routing 103
See “Configuring Static Routes” on page 103 to configure routes
manually, and “Learning Routes with OSPF” on page 106 to learn routes
dynamically.

SETDefault !<port> -IP NETaddr = <IP address> [<subnet mask>
[Ones | Zeros [MTU]]] | UnNumbered
If you are using a BOOTP server to obtain your IP addresses, see
“Assigning Addresses Automatically from BOOTP Servers” on page 108.
CAUTION: An IP address assigned to port 0 is considered the IP address
for all the interfaces. As a result, the bridge/router behaves as an IP host
for Telnet access and network management and stops routing IP packets.
Do not configure an IP address for port 0 if you want to route IP packets
2 Enable IP routing by entering:
SETDefault -IP CONTrol = ROute
Configuring Static A static route is a user-defined route by which a network can be
Routes reached. If you want to eliminate route advertisements required for
dynamic route learning and optimize the use of the available
bandwidth on slow serial data links, you must add the route as a
static route.
If a destination network is reachable with both a static route and a
learned route, the router uses the static route unless you specify the
optional Override value in the ADD ROUte command. If a learned route
is available, regardless of precedence, it overrides the static route when
using the Override value.
You should use static routes only if your network is small and
unchanging.
To set a static route, use:
ADD-IPROUte<IPaddress>[<mask>]{<gateway>|!<port>}<metric>
[Override]

CHAPTER 8: CONFIGURING BRIDGING AND ROUTING
To delete a static route, use:
DELete -IP ROUte <IP address> {<gateway> | !<port>}
The metric can be the number of routers a packet must travel through to
reach its destination, or a number associated with the path cost, for
example, speed. The metric is used to determine which route to use if
more than one route exists to a destination. The bridge/router uses the
lowest metric.

The gateway address is the IP address of port 3 on router 2. Because a
packet routed from router 1 to the Los Angeles network has to go
through one gateway, the metric is 1.

Learning Routes OSPF is a dynamic routing protocol that creates routing tables
w ith OSPF automatically. For information about other dynamic routing protocols like
RIP, see Using Enterprise OS Software.
Every 30 minutes or every time the router learns a route change for a
network, it uses multicast packets to report to its neighbors the following
types of information:
■
The networks and the directly connected routers
■
The metric associated with each directly connected router and
network
In an unchanging topology, OSPF only sends updates every 30 minutes
while RIP sends updates every 30 seconds. OSPF provides a significant
savings in network overhead when compared to RIP.
To enable OSPF on a specified port, use:
SETDefault !<port> -OSPF CONTrol = Enable
After OSPF is enabled, the router exchanges routing information with
other routers using OSPF.
For more information about fine-tuning your OSPF configuration, see
Using Enterprise OS Software.

Configuring IP Routing 107
OSPF over Dial-On-Demand Dial-Up Lines
If you are going to be running OSPF over dial-on-demand dial-up lines,
and you do not want the line to come up just for an OSPF packet,
configure a demand interface circuit using:
SETDefault !<port> -OSPF DemandInterface = Enable
With this setting, the router negotiates with the neighbor at the other
end of the point-to-point link. If the neighbor agrees that the
point-to-point link is a demand circuit, the router suppresses sending
OSPF hello packets, which allows the data link connection to be closed
when not carrying application traffic. The line will still be brought up
every 30 minutes to resynchronize routing table information. For the
demand circuit to be cost-effective, make sure that it is isolated from as
the interface.
Configuring Route By configuring route redundancy, you can use a back-up line to route
Redundancy traffic if your primary line fails. To configure a back-up line for route
redundancy, configure the line according to Chapter 7 and use either a
Enterprise OS Software.
Using a Static Route
protocol like OSPF on the primary line, use the Override option as
described in “Override Option” on page 106.
If you are using static routes for both lines, set the metric for the back-up
line to a higher number using the syntax in “Configuring Static Routes”
on page 109.
Using OSPF
Make sure the metric of the back-up line is higher than the primary line
using:
SHow [!<port> | !*] -OSPF Cost
If the cost for the back-up line is lower than the primary line, set the cost
manually to a higher number using:
SETDefault !<port> -OSPF Cost = <1-65535>

CHAPTER 8: CONFIGURING BRIDGING AND ROUTING
Assigning Addresses If the network administrator at a central site has configured the BOOTP
Automatically from server so that your SuperStack II bridge/router is a BOOTP client, then
BOOTP Servers Internet addresses may have automatically been assigned during the
automatic startup process. In this case, no action on your part is required.
If you are responsible for configuring the boot configuration file on the
BOOTP server so that automatic startup can take place, see Using
Enterprise OS Software.
To verify whether an Internet address was assigned during the
automatic startup process, enter:
SHow -IP NETaddr
If an Internet address is shown, then the SuperStack II bridge/router has
been assigned that address. If an address was not assigned, the
following message is displayed:
No IP address configured
For more information, or if you are unsure if an Internet address has
been assigned, contact the network administrator at the central site or
your network supplier.
Internet addresses are assigned for individual ports. To verify whether
an Internet address was assigned to an individual port, use:
SHow !<port> -IP NETaddr
When the bridge/router is installed for the first time, BOOTP requests
are sent from each connected port requesting a BOOTP server to
provide the SuperStack II bridge/router port with its Internet address
and other configuration information. The ports continue to send
BOOTP requests until the request has been answered. Also, every time
a path comes up, if no Internet address has been previously assigned to
it, BOOTP requests are sent requesting a BOOTP server to provide an
Internet address.
After your bridge/router has been installed for the first time, you can
control how it handles BOOTP requests using parameters in the
BOOTPC Service. For information on this service, see Reference for
Enterprise OS Software.

This section includes procedures to enable IPX routing and to optimize IPX
for dial-up lines. For information about fine-tuning your IPX
configuration, including running IPXWAN on a PPP link between the
bridge/router and a NetWare Multi-Protocol Router, and configuring
NLSP, see Using Enterprise OS Software.

NoWanBcast causes the IPX router to drop WAN broadcast packets to
prevent excessive traffic.
Configuring Static Routes dynamically learned are automatically purged from the routing
Routes table if they are not readvertised within a certain period of time.
If you want to add a route to the routing table that will not be purged
from the table, eliminate route advertisements required for dynamic
route learning, and optimize the use of the available bandwidth on
slow serial data links, you must add the route as a static route.
If a destination network is reachable with both a static route and a
learned route, the router uses the static route unless you specify the
optional Override value in the ADD ROUte command. If a learned route
is available, regardless of precedence, it overrides the static route when
the Override value is used.

110
CHAPTER 8: CONFIGURING BRIDGING AND ROUTING
The IPX router ignores any dynamic updates or backup routes on the
network when a static route is configured for a specific network. Static
routes are recommended only where the network topology remains
constant.
Define a static route using:
ADD!<port>-IPXROUte{&<remotenetwork>|Default}[<network>]
<media address> <hops> [Override] [hdrfmt]
Defining a Default Route
You can configure a static default route, which is subsequently added
to the routing table and propagated by NRIP or NLSP. Once a default
route is specified, packets destined to unknown networks (networks
not explicitly known or listed in the routing table) are routed to the
default router for subsequent routing. You can configure only one
default route per port.
Use this procedure to configure a default route so that unknown
destination packets can be properly forwarded. Define a static default
route using:
ADD !<port> -IPX ROUte Default <media address> <hops>
Override Option
If a destination network is reachable with both a static route and a
learned route, the router uses the static route unless you specify the
optional Override value in the ADD ROUte command. In that case, if a
learned route is available, regardless of precedence, it overrides the static
redundancy. The Override value is entered at the end of the command.

Kbps CSU/DSU
Module Autobaud
Feature
This section describes the autobaud feature, which allows the 56/64
Kbps CSU/DSU module to detect the baud rate automatically.
Prerequisites The two ports of the end bridge/routers must be configured to the same
port owners to allow the data link such as PPP to come up at the correct
baud rate.
Defaults The default setting is Autobaud ON.
You can turn off autobaud by setting the baud rate. For example, to set
the baud rate to 64 K, enter:
SETDefault !2 -PAth BAud=64
The autobaud feature is turned off and the CSU/DSU module is set to the
defined baud rate only. This terminates any autobaud that has already
started.
To turn on autobaud by setting the baud rate to auto, by entering:
SETDefault !2 -PAth BAud=AUto
Procedure This example sets up a 56/64 Kbps CSU/DSU module to communicate
with the central site NETBuilder router whose baud rate is already
configured.

Number using:
ADD !<port> -PORT DialNoList “<phone no>” [Baud = <rate>
(1.2–16000)] [Type = Modem | Bri | Sw56] | [Pos = <number>]
Enter this command for each phone number you want to add to the dial
list. If you do not specify a position, the number will be added to the end
of the list.
If you are using a dial pool, you may want to have several phone numbers
specifying different types (modem, BRI, or Switched 56) or baud rates so
if the first number fails on a 28.8 Kbps modem, for instance, the second
number is used for a 64 Kbps ISDN line.
You can use hyphens (-) in your phone number. For ISDN, the phone
number includes a dial prefix, country code, and area code and possibly a
subaddress. If you specify a subaddress, you must separate the phone
number from the subaddress with a semicolon (;).
You can configure up to 16 phone numbers per port.

dial number list that contains 10 phone numbers, enter:
ADD !4 -PORT DialNoList “510-555-7000” Pos = 2
The software inserts the new phone number into position 2. The phone
number that was previously in position 2 is now in position 3. If the
phone already exists in the dial number list, it will be moved to position
2. You can insert the same phone number twice by using blanks or
other redundant characters. You also can include the Baud and Type
keywords in any order when inserting phone numbers into the dial
number list.
Editing an Existing To edit an existing phone number in the dial number list, you can
Phone Number change the position in the list, change the baud rate, and change the
device type.
For example, if port 3 has already been assigned 612-345-3989 in
position 2 with a baud rate of 64 kbps, you can change the baud rate
by entering:
ADD !3 -PORT DialNoList “612-345-3989” Pos = 2 Baud = 14.4
Because the dial string is case-sensitive, make sure to match it exactly to
successfully edit an existing string when characters other than numbers
are used.
Deleting a Phone To remove a phone number from the dial number list, use:
Number
DELete !<port> -PORT DialNoList “<phone no>”
The phone number is case-sensitive and must be matched exactly.

Loopback Tests
This section describes the bridge/router response to a local loopback
assertion and how to perform a loopback diagnostic test on the WAN
and serial ports. It also describes the steps required to perform additional
types of loopback tests for a T1/FT1 module.
Response to Local If the bridge/router is connected to a DTE that asserts a local loopback
Loopback Assertion signal, the bridge/router displays:
Path x Detected DTE Loopback ON, switching to echo mode
The bridge/router in echo mode transmits the received data back to
the DTE.
When the signal is removed, the bridge/router displays:
Path x Detected DTE Loopback OFF, switching to normal mode

Prerequisites
Before beginning this procedure, complete the following tasks:
■
Attach a console or Telnet to your SuperStack II bridge/router.
■
Configure the ISDN port according to “Configuring ISDN on the WAN
Port (43x, 44x, 53x, and 54x)” on page 70.

134
APPENDIX A: TROUBLESHOOTING
To perform a loopback test on the built-in ISDN port, follow these steps:
1 Assign each path to separate ports, if necessary, by entering:
ADD !3 -PORT PAths 3.1
ADD !4 -PORT PAths 3.2
2 Set the rate adaption parameter to automatically detect the speed of the
sending interface using:
SETDefault !<connectorID.channelID> -PAth RateAdaption = Auto
In the example shown in Figure 9, the test originates from path 3.2 and
targets 3.1. To specify path 3.2, enter:
SETDefault !3.2 -PAth RateAdaption = Auto
3 Configure the ports for loopback testing by entering:
SETDefault !3 -PORT OWNer = Loopback
SETDefault !4 -PORT OWNer = Loopback
4 Add the phone number of path 3.1 to the dial number list of port 4
using:
ADD !4 -PORT DialNoList “<phone no>” Baud=64 Type=Bri Pos=1
5 Establish a connection between the two B channels by dialing out on one
channel and dialing into the other using:
DIal !<path>
To dial path 3.1 from path 3.2, enter:
DIal !3.2
Path 3.2 places a call to the number configured in step 4, which is the
number for path 3.1. It is not important which port originates or answers
the call as long as the port does not try to call itself.
6 When the connection is successfully established, select the loopback
testing mode by entering:
DLTest TestMode Loopback
7 You can specify the number of seconds the test should run. Enter this
value any time before entering the DLTest START command. If a value is
not specified, an infinite time duration is assumed. To run the test for a
specific number of seconds, use:
DLTest TestDuration <seconds>
Use caution when running for a specified test duration. The test ends
abruptly as soon as the time duration expires and a discrepancy between
the number of packets transmitted and the number received may result.

Performing Loopback Tests 135
8 Start the DLtest using:
DLTest Start <sendingport>, <receivingport>
To start the DLTest and designate port 4 to send the DLTest data and port
3 to receive and loop back the data, you would enter:
DLtest START 4,3

Loopback Test on a
Serial Port
Figure 14 shows the data flow that occurs when a loopback test is
performed on a serial line. A modem or CSU/DSU is required in this
configuration.
Figure 14 Serial Loopback Testing
Before running the serial loopback test, complete the following tasks:
■
■
Place the modem or CSU/DSU in local loopback test mode. For
information, see the documentation that accompanies your modem
or CSU/DSU.
■
Verify the path and port number of the serial port you are testing by
referring to Table 14 or Table 15 on page 69.
To perform a loopback test on the serial port, follow these steps:
1 Set the line type to Leased using:
SETDefault !<path> -PATH LineType = Leased
2 Set the owner of the serial port you are testing to LoopBack using:
SETDefault !<port> -PORT OWNer = LoopBack
3 Select the loopback test mode by entering:

Performing a Memory Dump 145
If the number of received packets equals or approximately equals the
number of transmitted packets, your serial line has passed the serial
loopback test. If your serial line does not pass the test, verify that your
bridge/router is cabled correctly and that the software is configured
correctly. Also, check the number of packets transmitted and the number
of errors by entering:

6 Stop the serial loopback test by entering:
DLTest Abort
7 Restore the owner of the wide area port you are testing from loopback to
your protocol using:
SETDefault !<port> -PORT OWNer = PPP | FrameRelay | SMDS | Auto
Failure to perform this step causes the port to remain in loopback mode
preventing connectivity through the port. Performing diagnostics on the
port will reveal only that the port is down.
Performing a
Memory Dump
If a SuperStack II bridge/router unexpectedly stops functioning, it
performs a memory dump. A memory dump provides a view of the
internal state of the system, which can help Technical Support determine
the cause of the failure.
By default, the system performs a partial dump to available flash memory.
If you want a full dump to a TFTP server on the local Ethernet network,
you must have the following items available:
■
IP addresses and subnet masks of the SuperStack II bridge/router, TFTP
server, and possibly, the gateway leading to the network segment
where the TFTP server is located
■
■
■
■
A TFTP server on the local Ethernet network
Authorization to write to the TFTP server
10 MB of available disk space on the TFTP server
The SuperStack II bridge/router configured to dump to the TFTP server
The procedure to obtain a memory dump involves setting up destination
IP addresses and a file to hold the memory dump information. The
bridge/router uses the IP addresses to transmit the memory dump in a file
across the network to a TFTP server.

APPENDIX A: TROUBLESHOOTING
Notice to users with UNIX TFTP servers: Some UNIX TFTP servers do not
have the capability to create files if they do not exist, but can overwrite an
existing file. Therefore, you must first create a file with the expected
dump file name on the UNIX TFTP server. The procedure for creating such
a file is described in “Creating a File for the Memory Dump” on page 147.
Configuring the The Dump Destination parameter selects where the contents of
Dump Destination bridge/router memory are stored in case of a crash.
1 Connect to the bridge/router through the Console port or through Telnet.

network attached to the Ethernet port.
8 Select Dump Destination Directory on the Dump Destination menu to
configure the location on the TFTP server to which the dump file will go.
The default destination is /dump.
9 Enter the target directory on the TFTP server.
Usually, the target directory is the default TFTP directory. For example, if
the TFTP directory is /home/TFTPdir, and the target directory configured
on the bridge/router is /dump, then the actual target directory is
/home/TFTPdir/dump. Make sure this directory exists on the TFTP server,
as it will not be created by the bridge/router, or the TFTP process when a
TFTP transfer is initiated.
10 Type Q repeatedly to exit the System Configuration menus and return to
the Enterprise OS # prompt.
Obtaining the MAC You need to obtain the media access control (MAC) address of the
Address SuperStack II NETBuilder SI bridge/router. This is necessary because the
system creates a dump file on the TFTP server named dmXXXXXX.dmp,
where XXXXXX are the last six characters of the MAC address of the
Ethernet port (port 1) of the bridge/router.
To display the MAC addresses, follow these steps:
1 At the Enterprise OS # prompt, enter:
SysInfo
2 Record the MAC address for port 1 when it is displayed. You will use this
number in the next procedure.

a listing of the current processes. See your documentation pertaining to
the IP stack on the TFTP server if you have any problems.

APPENDIX A: TROUBLESHOOTING
To create a memory dump file, follow these steps:
1 On a UNIX TFTP server, create a file with the name dmXXXXXX.dmp,
where XXXXXX is the last six characters of the MAC address of the
Ethernet port (port 1) of the SuperStack II bridge/router.
For example, if the last six characters of the MAC address of the
bridge/router are 06BA6A, enter:
touch dm06BA6A.dmp
2 Ensure that all users have permission to write to the target directory and
filename. To determine this on a UNIX system, enter:
ls -a
3 To change write access permissions on a file or directory, enter:
chmod 666 dm06BA6A.dmp
See the UNIX system documentation if you have any problems.
Verifying the TFTP To verify that a TFTP transfer can occur from the SuperStack II
Process bridge/router to the TFTP server, follow these steps:
1 Obtain a listing of the files on the SuperStack II bridge/router to select
one to transfer using:
df <directory>
2 If you are using a UNIX TFTP server, create a zero byte file with the name
of the file you selected, and with the proper permissions, using:
touch <filename>
chmod 666 <filename>
3 Transfer the selected file from the bridge/router to the TFTP server using:
COpy [<device>:]<src_filename> [<device>:][<dest_filename>]
For example, to copy a source file named system to destination /dump/
using the TFTP server at IP address 139.88.132.192, enter:
COpy a:/primary/system 139.88.132.192:/dump/system

name as part of the command, you must precede the service name with a hyphen. For
example, in the command:
SETDefault -BRidge CONTrol = Bridge
the hyphen must be included with the service name BRidge when entering the command.
Enclose a list of values, one of which must be entered. For example, in the syntax:
braces { }
SETDefault!<subaddr#>-GatewaySubAddrMap={(<IPaddr>|<PSAPaddr>)|
None}
you must enter either an IP address, presentation service access point (PSAP) address, or the
keyword None when entering the command.
exclamation mark ! A number preceded by an exclamation mark represents a port, virtual port, or path number.
For example, in the syntax:
SHow [!<port>] -DECnet CONFiguration
the exclamation mark must be included before the port number when entering the
command.

NoFiltering], [SECurity | NoSECurity], [FwdSubnetBcast |
NoFwdSubnetBcast], [FwdAllSubnetBcast] | NoFwdAllSubnetBcast)
can be abbreviated to:
SETD -IP CONT = ([RO | NRO], [RSR | NRSR], [SL | NSL], [F | NF],
[SEC | NSEC], [FSB | NFSB], [FASB | NFASB])
The following abbreviated command enables IP routing, packet filtering,
and security:
SETD -IP CONT = (RO,F,SEC)
For consistency and clarity in the Enteprise OS and NETBuilder family
guides, the full form syntax is provided. However, you can use the
abbreviated form by only typing the uppercase portion of the command
and supplying the appropriate values.
Variations in
Command Syntax
Each command has its own syntax. When a command is used for
configuring parameters, its syntax or values may change according to the
parameter and the service. For example, the SETDefault command sets
the NetMapTime parameter in the SYS Service and the MaxAge
parameter in the STP Service. In the following example, the general
command syntax is followed by the syntax variations (different values for
different parameters) appropriate to the parameter associated with a
service:
SETDefault <parameter> = <value>
SETDefault -SYS NetMapTime = <number> (0 to 120 seconds)
SETDefault -STP MaxAge = <seconds> (6–40)

Using Aliases 157
Entering When you are configuring or displaying a parameter, service names must
Service Names in be provided to differentiate commands that appear in more than one
Command Lines service. The service name may be entered in abbreviated form. The
service name must be preceded by a hyphen. For example, to indicate
BRidge Service, type -br.
Abbreviated service names are indicated in uppercase in this guide.
There are three exceptions:
■
If you have previously set the CurrentServices parameter to the desired
service, you do not need to enter the service name. The system
prompt indicates the current service if a single service was set with the
CurrentServices parameter. If multiple services are set, the system
prompt is displayed. For information on using the CurrentServices
parameter, see Reference for Enterprise OS Software.
■
■
If the command is for a Global parameter, (the command affects the
entire system environment) you must not specify a service name. For
descriptions of those parameters affecting the system, see Reference
for Enterprise OS Software.
If the parameter name is unique.
Using Aliases
To avoid entering lengthy commands at the prompt, you can customize
the command name using an alias. You can create an alias to represent
any command. Use the following syntax to define an alias:
ADD -SYS ALias <aliasname> <arguments ...>
For example, if you use the SHow -SYS NetMAP command often, create
an alias called ntmap by entering:
ADD -SYS ALias NTMAP SHow -SYS NetMAP
Each time you want to display the network map, enter:
ntmap

Description
Repeats the previous command.
Repeats the command line numbered n.
!<n>
! –<n>
Repeats the command whose number is the current command number minus n. The
current command number is printed on the screen preceding the prompt. For
example, if the current command is 100 and n is 2, command number 98 is repeated.
!<string>
Repeats the most recent command that starts with string. The SHow History command
might display the following commands:
166 setdefault !1 -path control = enabled
167 show -path configuration
168 show history
169 set screenlength = 23
170 setdefault -bridge control = bridge
171 show statistics ?
If you enter !setd at the prompt, the most recent occurrence of the SETDefault
command (setd -br cont = b, number 170) is executed.
!?<string>
Repeats the most recent command containing string.
^<string1>
^<string1>^<string2>
Repeats the most recent command that contains string1. If string2 is specified, it
substitutes for string1 in that command. For example, if you entered this SETDefault
command with a typing mistake:
seed welcomestring = “You are talking to the 3Com NETBuilder”
To repeat the command with the correct spelling of SETD, you do not need to reenter
the entire command. Enter the following command:
^seed^setd
The following command is displayed and executed:
setd welcomestring = “You are talking to the 3Com NETBuilder”

Privilege Level 159
Privilege Level
The privilege level determines which commands and parameters you can
level is Network Manager, which allows you access to all the commands
and parameters.
You can create users with either User or Network Manager privilege.
Some commands are available only to root. For more information, see
“Adding User Accounts” on page 60.
ISDN-Related
Syntax Variation
(Models 43x and 44x)
Built-in ISDN ports use a different path numbering convention from
other paths. Each B channel is assigned a different path. For instance,
3.1 and 3.2 are path numbers for a built-in ISDN port, where 3 is the
connector ID, and 1 and 2 are the channel IDs. Some commands
require you to specify the connector ID and channel ID of an ISDN
path.
When using an ISDN TA connected to a serial port, both B channels are
assigned the same path number. You do not need to use special ISDN
syntax.
The syntax variation for these parameters is presented in the following
format:
For non-ISDN interfaces SETDefault !<path> -PATH CONtrol = (Enabled | Disabled)
SHow !<path> -PATH CONtrol
For built-in ISDN SETDefault !<connectorID.channelID> -PATH CONtrol = (Enabled |
Disabled)
interfaces
SHow[!<connectorID.channelID>|!<connectorID>.*]-PATHCONtrol
SHowDefault[!<connectorID.channelID>|!<connectorID>.*]-PATH
CONtrol
The software menus and help string do not give the syntax variation for
ISDN interfaces. Although the software does not give this variation, you
must input the syntax for these ISDN-related parameters as shown in this
guide.
Some parameters in the ISDN-specific software are connector-related,
which require that you specify a connector number (<connectorID>), for
example, 3 only. Other parameters in the ISDN software are
channel-related, which require that you specify both a connector and

160
APPENDIX C: SYNTAX CONVENTIONS
channel number (<connectorID>.<channelID>), for example, 3.1. When
specifying both a connector and channel number, you must separate the
two numbers with a decimal point.
If you do not specify a channel number in a command syntax that
requires a connector and channel number, the bridge/router assumes the
first channel associated with the specified connector. For example, if you
specify only connector number 3 when the command syntax requires that
you specify both a connector and channel number, the bridge/router
assumes 3.1.
If you want to specify all channels associated with a connector in a
command syntax, specify the connector number, a decimal point, then an
asterisk, for example, 3.*
A path is the physical interface that connects the bridge/router to a
physical medium such as an Ethernet bus, a token ring, or a serial line. In
is transmitted.

■
FX — Runs over fiber. FX does not connect to the SuperStack II
NETBuilder SI bridge/router, but you can use FX in your network
between appropriate devices.
■
T4 — Runs over Category 3 or better UTP or shielded UTP. T4 does
not connect to the SuperStack II NETBuilder SI bridge/router, but you
can use T4 in your network between appropriate devices.
Follow the steps in the next section to design a valid Fast Ethernet
network.
Creating a Valid Netw ork
A Fast Ethernet network consists of collision domain diameters formed by
cabling and/or repeaters between two DTE devices. A DTE device is a
bridge/router, switch, or end station that contains a media access
controller (MAC). Repeaters usually do not contain a MAC.

LAN Connector and Cables 167
To create a valid collision domain diameter, you must adhere to the
diameter guidelines in Table 22:
■
UTP (running TX or T4) — Maximum cable span length is ≤100 m.
Fiber (running FX) — Maximum cable span length is ≤412 m.
■
Figure 21 shows examples of collision domain diameters.

A DCE must always connect to a DTE, and vice versa. If you need to
between the two devices.
For example, a SuperStack II bridge/router is a DTE. To connect the
bridge/router to another DTE, such as a mainframe, use a crossover

PROVISIONING YOUR ISDN LINE
E
This appendix provides U.S., Canadian, German, and Dutch provisioning
information for the built-in ISDN port on model 43x, 53x, 44x and 54x
SuperStack II NETBuilder SI bridge/routers.
Ordering U.S. and
Canadian ISDN BRI
Services
To order ISDN service from your telephone company, follow these steps:
1 Call the telephone company and ask for the ISDN representative.
2 Tell the representative you want ISDN service for a SuperStack II
NETBuilder SI bridge/router, and that you have the following information:
■
Line provisioning
ISDN outlet type
■
3 Tell the representative that the Bellcore ISDN ordering code (IOC) is
“Capability R.” The IOC tells the telephone company which parameter
settings to use for SuperStack II bridge/routers.
Not all Regional Bell Operating Companies use IOCs.
4 If you have a model 43x or model 53x bridge/router with an ISDN S/T
connector, ask for an NT1 to connect your SuperStack II bridge/router to
the ISDN line. (You can also purchase an NT1 from a reseller.)
5 Ask for the following information to fill out the ISDN Information Sheet:
■
ISDN Sw itch Type. Ask the representative which ISDN switch type
your line uses. Place a check mark next to that switch on the ISDN
Information Sheet. Each switch type has a corresponding provisioning
information table later in this section.
■
Number of ISDN Phone Numbers. Your ISDN line can support one
or two phone numbers. Specify how many phone numbers you are
ordering.

APPENDIX E: PROVISIONING YOUR ISDN LINE
■
■
Phone Numbers. Ask the telephone representative for your ISDN
phone numbers and write them in the space provided.
Service Profile ID (SPID) Number. Ask the telephone representative
for your SPID numbers. ((For a point-to-point line only one SPID may
be provided. For a multipoint line, the telephone representative should
provide two SPID numbers.) A SPID number has 10–15 characters; for
example, 0155512120. Your switch type may not require the SPID
number.
Your telephone company gives you the phone number and SPID number
after it installs your line.

SPIDs When you request services, you may also need the following information
about SPIDs and other service attributes:
■
Request multipoint, initializing terminal service; the maximum number
of terminals is two. The service provider supplies you with two SPIDs.
■
If you request ISDN service from an AT&T 5ESS service provider and
the switch is running custom (or non-National ISDN 1) software, the
format is:
01 + 7-digit telephone number + 1-digit suffix.
■
■
If you request a different telephone numbers for each B channel, the
suffix can be the same. A suffix of 0 is typical in this case. If you decide
to use the same telephone number for both B channels, use a
different suffix so that the two SPIDs are unique.
If you request NI-1 (National ISDN 1) service from an AT&T 5ESS
service provider, the format is:
01 + 7-digit telephone number + 1-digit suffix + 2-digit TID (terminal
identifier).
Download from Www.Somanuals.com. All Manuals Search And Download.
NT1s and Power Supplies 193
■
■
The SPID numbers must be unique. The 2-digit TID can be any number
from 0 to 62. The TID has no effect on the operation of the SuperStack
II bridge/router, but it is a necessary part of the SPID that the
bridge/router uses to gain access to the ISDN network.
If you request ISDN service from a Northern Telecom DMS-100 service
provider, the format is:
Area code + 7-digit telephone number + 0 to 8 digit suffix + 2 digit TID.
■
■
■
The TID can be any number from 0 to 62, but needs to be unique so
that the SPIDs are also unique. This format applies when the switch is
running Custom and NI-1 (North American 3) versions of software.
If you order AT&T 5ESS Custom ISDN services, choose either a Type A or
Type E terminal. The Type E terminal is preferable because it is for data
only.
Do not request supplementary services, such as autohold or
conference, because a SuperStack II bridge/router does not support
them.
NT1s and Pow er
Supplies
The models 43x and 53x bridge/routers do not come with an NT1. North
American telephone companies require an NT1 and a power supply for
every ISDN line. Your service provider or telephone company can provide
you with an NT1 and power supply for a small monthly fee. However, you
may prefer to purchase it from an ISDN equipment vendor. The NT1 and
power supply may come in a single, standalone box or the two may be in
separate units. In this discussion, the two units together are referred to as
an NT1.
The model 44x and model 54x bridge/routers have an integrated NT1.
Telephone companies in North America use two kinds of NT1s,
differentiated by the data encoding scheme used in transmitting data
between the NT1 and the telephone company’s equipment. The two data
encoding schemes are 2B1Q (two bits mapped into one quaternary symbol)
and alternate mark inversion (AMI). The 2B1Q scheme is the dominant
method in use today. The AMI scheme is older and rarely used.

Ordering German
ISDN BRI Services
To order German ISDN services, follow these steps:
1 Acquire a form entitled “Telefondienstauftrag im ISDN
(Euro-ISDN-Anschluß)” from the Telekom.
2 At the top of the form, select “Neuanschluß.”
3 Under “Auftraggeber,” provide the requested information.

standard basic rate interface (BRI) service. Under “Anschrift Standort,”
provide the requested information.
5 Under “Anschlußnutzung,” specify “Mehrgeräteanschluß.”
By specifying “Mehrgeräteanschluß,” you are requesting a connection for
multiple types of equipment, such as bridge/routers, telephones, faxes,
and computers.
6 Sign your name at the bottom of the form.
The SuperStack II bridge/router software does not currently support the
1TR6 switch type. If you have an existing 1TR6 connection, request that
the connection be changed to a Euro-ISDN connection using this form. In
case the Telekom requests this information, the approval number for
Germany (Bundesamt Für Zulassungen In Der Telekommunikation) is
A115352E.
