FCC NOTICE

IC (Canada)

This device complies with Part 15 of the FCC rules. Operation is subject to the following two conditions:

1. This device may not cause harmful interference.

2. This device must acc ept any interference received, including interference that may cause
unde sired operation.

This equipment has been tested and found to comply with th e limits for a Class A digital devi ce, pursuant
to Part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful
interference when the equipment is operated i n a commercial environment. This equ ipment uses, gen­erates, and can radiate radio frequency energy and if not installed in accordan ce with the operatiors
manual, may cause harmful interference to radio communications. Operation of this equipment in a res­idential area is likely to cause interference in which case the user will be required to correct the inter­ference at his own expense.

WARNING: Changes or modifications made to this device which are not expressly approved by the party
responsible for compliance co uld vo id the user’s authority to the equipment.

The Industry Canada label identifies certified equipment. This certification mean that the equipment
meets certain telecommunications network protective, operational and safety requirements. The
department does not guarantee the equipment will operate to the user’s satisfaction.

Before installing this eq uipment, u sers should ensure that it is permissible t o be connected to t he facilities
of the local telecommunications compan y. The equipment must also be installed using an acceptable
method of connection. In some cases, the company’s inside wiring associated with a single-line indi­vidual service may be exte nded by means of a certified connector assembly (telephone extension cord).
The customer should be aware that compliance with the above conditions may not prevent degradation
of ser vice in some s ituatio ns.

Repairs to certified equipment should be made by an authorized Canadian maintenance facility desig­nated by the supplier. Any repairs or alter ations ma de by the user to thi s equipme nt, or equipm ent ma l­functions, may give the telecommunications company cause to request the user to disconnect the
equipment.

Users should ensure, for their own p rotection, that the electrical g round connections of the power facility,
telephone lines and internal metallic water pipe system, if present, are connected together. This pre­caution may be particularly important in rural areas.

CAUTION: USERS SHOULD NOT ATTEMPT TO MAKE SUCH CONNECTIONS THEMSELVES,
BUT SHOULD CONTACT THE APPROPRIATE ELECTRIC INSPECTION AUTHORIT Y, OR
ELECTRICIAN, AS APPROPRIATE.

This digital apparatus does not exceed the Class A limits for radio noise emissions from digital apparatus
set out in the Radio Interference Regulations of the Industry Canada.

Product Overview

The SmartSwitch 1800 is a high-performanc e, multiprotoco l bra nch access device,
providing the ability to transmit LAN data, legacy da ta (e.g., SDLC, bisync, async) ,
voice, and fax over a single frame re lay link. A powerful manag e ment capability
allows allocation of frame relay bandwidth to ensure that each type of tr affic receives
the necessary qua lity of service.

The SmartSwitch 1800 shares much functionality and compatibility with Cabletron’s
FRX 4000, FRX6000, and the Frame Relay Module (FRM) for the Sma rtSwitch 9000.

A SmartSwitch 1800 with a video in terfac es features an intuitiv e , menu-based ma n­agemen t str ucture th at allows complete lo cal and remote co ntr ol of other Sma rtS witch
1800s, as well as other Cabletron frame relay access devices.

User Interfaces

A Smar tSw itc h 1800 contains fou r serial ports in the Voice/Data models and up to
eight in the da ta-only models. Eac h s eria l port s upport s any of the protocols that are
installed (see Tabl e 1-1), with the exception of Voice, whic h is supported on two
Voice ports (and can be transported over an y serial port configured for f r ame relay).
Each devi ce also includes one LA N port —Et hernet or Toke n Ring, depending on the
model.

Operator Interfaces

After it has been installed and configured, a SmartSwitch 180 0 can functi on with no
keyboard or video device. (Therefore, such devices are not standard equipment.)
However, configuration , file copy (backup, restore, transfer, etc.), and monitoring
operations require a key board and screen, in on e of several f orms.

The typical method of connectin g to a SmartSwitch 1800 is via an ASCII (VT100­type) terminal (configured for 9600 bps, 8 data bits, 1 stop bit, no parity), or a terminal
emulat or on a PC running Procomm Pl us for Windows . Eac h SmartSw it ch 1800 is
shipped with cabling to support connection to an ASC II terminal or a PC.

Quick Start

Chapter 2

Getting Started

The S martS witch 1800 Ins tallation & Setup Guide (shipped with ea ch unit) describes
the procedure for connecting to the SmartSwitch from a local or remote keyboard and
video device. Once this has been done, the Smar tSwitch must b e customized for the
devices to which it will connect , the traffic it will receive and transmit, and various
operating parameters that can be set to your specific needs.

Much of the c onfiguratio n can be perf ormed from an existing central- site FRX6 000
via remote control of t he Sm artS w it c h 18 00 . A t a mi n im um, ho w ever, so m eo ne m us t
config ure a remote cont rol ID and a physical port on each new SmartSwi tch 1800, to
allow th e central- site FRX6000 to gain access to the SmartSwitch 18 00.

The basic steps you should tak e to get the Sm artSwitch up and running are:

1. Read the remainder of this ch apter, as it explains the user interface on a Smart­Switch 1800. This information will help you understand the menu operations that
are necessary to configure the SmartSwit ch for your app lication.

2. R eview the default databa se parameter setti ng s, listed in tables throughou t
Sectio n II. (A list of tables can be found in the T able of Conte nts.) Ma ny pa ram-
eter s can be left at the default s etting s, but some must be rec onfigured to match
your specific needs.

3. Fill in Ta bl e 2-2 (on page 2-3), to identify the physical interf ace, protocol, an d
co nnected device on each physical port. You will need more information when
configuring database reco rds, but these tables can be u sed as convenient refer­ences.

4. Log into the menu operations, if not already done. This is descr ibed in the Smart-
Switch 1800 Installation & Setup Guide, as well as on p age 2-4.

5. Set the correct d ate and time, as described on page 2-9. Event (alarm) messages,
repo rts, and some display s inclu de the current date and time as set in the Smart­Switch. They should be accurate, for proper network monitoring and man­agement.

6. Ch ange t h e login password, i f d e s ir ed. The defaul t p a ssw o rd is
chan ge t his t o any pas swo rd of up to 14 chara cte rs, as de s cri bed on page 2-9.

7. Configure the necessar y database records: Node (Chapter 4), SNMP parameters
(Ch apter 17) if SNMP manageme nt will be performed , protocols ( Cha pter 5),
ne tw ork port s (frame relay – Chapter 7) or X.25 – Chapter 8), plus LAN inter-
faces an d legacy access ports (miscellaneous chapt ers in S ection II) .

The protocols that can be assigned to ports depend on the model of SmartSwitch 1800 and
the op tions that were purcha sed. All pos sible protocols are listed below:

Ports 0–3: Frame relay, X.2 5, SDLC, BSC Interactive, BSC Batch, Async.
Ports 4, 5: Voice.
LAN Port: IP, IPX, Bridge, LLC2.

Note that the LAN protocols (IP, IPX, Bridge, LLC2) are also assigned to physical frame
relay ports via interface records that map the protocols to the physical ports.

Lo ggin into th e Main Menu

Configuratio n (see Secti on II) and management (see Section III) operations are
access ed via a menu structure, using a keyboard and video device. Once the Smar t­Switch has been configured and is operational, it does not need a keyboard and video
device; however, they are necessary to get the unit up and running.

When running outs ide the menu operatio ns, a display will be similar to the following
figure, and will show the curr e nt status of all ports on the node. (Th is display is
described in detail on page 2-4.)

As a SmartSwit ch 18 00 boots , screen i nfor mation (ass uming ther e is a s cree n) verif ies
configuration file format and displays any e rrors. This data is displaye d only until the
SmartSwitch software is running; however, it is save d in a file named BOOTRPT.TXT,
and the operato r can later display it. This can be us ed as a tool to verify tha t startu p of
the node proceeded without errors. If there is an err or reported, the data may aid in
fixing the problem.

If the device is shut down, then rebooted, the existing BOOTRPT.TXT file will be
renamed BOOTBAK.TXT, an d a new BOOTRPT . T XT will be created. BOOTRPT .TXT
and BOOTBAK.TXT can be us ed as foll ows:

1. Display and review th e data fr om the “cur rent” boot of the device.

2. Address any reported problems.

3. Re-boot the device. (This copies the previous boot data to a backup file.)

4. Displa y th e new boot data, and compare it t o the previou s data. This will s how
whether the problem was fixed. Also, a problem that occurred during the previous
boo t-up will often be clear e d up by re-booting.

Section II

Configuration

Introduction to Database Configuration

Each SmartSwitch 1800 contains its own configuration database, which contains
information iden tifying the hardwar e compone nts , and defines the operating param­eters of the hardware an d software.

Each datab ase file contains defin ing parameters for a specific component; for
example, physical p orts, sub scriber IDs, or IP interfaces.

Befo re the SmartS witch 1 800 can prope rly oper ate, all necess ary datab ase par ameter s
must be configured. The necessary configuration depends on the installed hardware,
the routing and access protocols that will be used, and the devices that will be con­nected to ports in the SmartSwitch .

Database Set up Recommendat ions

Chapter 3

Many database parameters are configured with default values, ma ny of which may not
ne e d t o b e cha n ged fo r your co nf i gu ra t ion. O ther parame ters , ho w e ve r , defi ne t h e sp e­cific co nfiguration. For example, each devi ce must have unique identifiers if the
device will be used in remote control, file transfer, or alarm reporting operations. Also,
each dev ice will most likely differ in whi ch ports will run which protocols , and what
the physical interfaces on those ports will be.

B efore proce eding w i t h yo ur c on f igurat i o n, you sh ou l d b e a w are o f al l th e parame t ers
that mu st be, or can be, specified. You should first note the d efault v alues, since many
may be correct as is. Tables of parameters, including their valid and default values,
can be found throughout Section II. The Ta ble of Conte nts contai ns a list of al l ta bles .

You shoul d also be familiar with all device s that will connect to the SmartSwitch
18 00 ; s om e h ave requir e me n t s or re s t ric t ions .

Some t hings you must know before configuring the data ba se are :

●

The information in Table 2-1 (on pa ge 2-2).

●

T he addresses th at must be speci fied in various po rt and inter face rec ords. Each
SVC subscriber must be assig ned an ID ( described on page 8-21) that wi ll be
used as a called or calling address in call setup packets. IP, IPX, LLC2, and
SNMP also requi re addres ses for identificat io n of network s and devices .

For reference, th e following table describes what happ ens to a MAC address at the
SmartSwitch 180 0 if the sending and receiving for mats ar e different.

Table 3-1 MAC Ad dre ss Conversion

Received from: Forwarded to: Action taken:

802.3 802.5 Converts MAC header to LAN header (including cached

802.5 Nativ e LLC2 Drops LAN h eader

Native LLC2 802.3 Adds MAC header
Native LLC2 802.5 Adds LAN header (including cached RIF)

LAN IDs can be configured in two places:

●

LLC2 node defaults, to identify a virtual bridge that connects the LLC2 function
to LAN in terfac es.

●

LLC2 frame relay interfaces using 802.5 Source Route Br id ge format, to
identify the ring number used by a source-route bridge at the remote end. (This
ID is normally assigned by a system administrator.) Note that the LAN ID on an
origina ted LLC2 interface mus t matc h the LAN ID on the corresp onding te rmi­na ted interf a ce.

Be aware th at when conf iguring thes e reco rds, LAN IDs mus t be entere d in hex. Also
note that, other than the matching IDs on each originat ed/termin ated interface pair,
each LAN ID must be unique within the network on which the SmartSwitch 1800 will

LLC2 Funct io n

Internally, LLC2 connects to interfaces via the Bridge prot ocol. LLC2 Host and
Interface records act as both o rigination and term ination points for LLC2. For

RFC 1490 Format

An RFC1490 format used for SNA traffic is configured in the frame relay LLC2
Interface/Bridge Por t record. The options, in order of lowest overhead to highest
overhead, are:

●

Nat ive LL C 2 (al so known as BN N, or Bounda ry Net work Node). When this
format is used, no MAC addresses are transmitted acr oss the frame relay link.

●

802.5 S RB (source route bridge) (al s o know n as BAN, or Boundary A ccess
Node. (SmartSwitch 1800 devices support BAN type 1). This format is gen­erally used for 3174 gateways and AS/40 0s, because they need to see a MAC
address ).

●

802.3 TB (transparent bridge), used when talking to routers that cannot do BAN
or BNN.

Subscriber IDs

Subscriber IDs are only used locally within each SmartSwitch 1800 to link records
(e.g. SDLC PU record to LLC host reco rd), unless the device is running X.25, SDLC/
L LC2 primary (the S mart Sw it ch 1800 would be S DLC s econdary to the FEP), or
logical ports (i.e. , QLLC), in which cas e the subscriber IDs correlate to the sta tic
route s defined in the subscriber routing tab les.

PU 1 Devices

PU1 devi ces can not be defined as Token R ing attac he d t o the AS/ 400. AS/ 400 pro­grammers might try to get around this by defining different device types (i.e., 5494/
PU 2.0 or PU 2.1) to 5294 and 5394 PU1 controllers. However, when this is done, the
ACTPU is not spoofed internally, and is sent to the rem ote controlle r. The Smart­Switch 1 800 cannot accept and respond, and the co ntroller and AS/400 will go into
error mode. T he 5394 can be RPQed to act as a PU2.1 device ( see IBM RPQ
8Q07 75 ); 52 94 co nt r ol l er s ca n no t b e R PQ e d, and m us t be a t ta ched a s SD LC de v i c es ;
there are no issues with the 5494, as it is a PU2.0/2.1 node. 5294s and 5394s can only
be directly connected to Sm artSwitch 1800 devices via SDLC or X.25 with spe eds up
to 64 kbps. 5494s can be connected via SDLC or frame relay with speeds to 128 kbps,
or by Token R ing or Et hernet/ 802. 3.

●

Physical SNA port ( Cha pter 6 and Chapter 9 ). The link station SDLC/LLC2
co nve rs ion point is also defined in this record, under SNA PU Parame ters.
(These parameters act as both LLC2 Originated Host and Originated Interface
records.)

●

Terminated LL C2 Host (Chapter 9) , which points to the frame relay interface.
No te that the remote Sma rtSwitch 1800 mus t have an Origina ted LLC2 Host .

●

Terminated LL C2 Interface (Chapter 9), which defin es an LLC2 term inatio n
point at the fram e relay interface. Note that the remote SmartSwitch 1800 mu st
have an Originated LLC2 Interface.

●

SVC Subscriber (Chapter 7), to route the incoming connection reque st from the
fr a me relay LLC2 Termina ted Hos t to the SDLC port. Note that th is record is
not req uired o n the rem ote Sm artSwit ch 18 00, b ecause th at devi ce orig inates the
co nne ct ion (i.e., it is not being called).

LAN IDs can be configured in two places:

●

LLC2 node defaults, to identify a virtual bridge that connects the LLC2 function
to LAN in terfac es.

●

LLC2 frame relay interfaces using 802.5 Source Route Br id ge format, to
identify the ring number used by a source-route bridge at the remote end. (This
ID is normally assigned by a system administrator.) Note that the LAN ID on an
origina ted LLC2 interface mus t matc h the LAN ID on the corresp onding te rmi­na ted interf a ce.

Be aware th at when conf iguring thes e reco rds, LAN IDs mus t be entere d in hex. Also
note that, other than the matching IDs on each originat ed/termin ated interface pair,
each LAN ID must be unique within the network on which the SmartSwitch 1800 will
oper ate.

LLC2 Funct io n

I nternally , L LC2 connects to interf aces via a virt ual bridge. LLC2 Host and Interf ace
records act as both origin a tion and terminat ion points for LLC2. For example, if you
are configuring SDL C-to-L LC 2 conversio n to be transmitted over frame relay to a
Token Ring host, the following is the logical LLC2 record flow: SNA Port/PU record
(Chapter 9), with the parameter

Introduction

Chapter 7 FRM

Configuring Frame Relay

Fram e relay p orts in the Sm artSwi tch 1800 are u sed to carr y frame relay traffi c, as well
as other protocols encapsulated in frame relay (per RFC 1490, via logical X.25 ports
over frame relay) . A fram e relay por t c an act as phys ical DCE, con necting to end- user
dev ice s , or DTE, connec ti ng to a net work or frame rel ay P VC.

Frame relay support includes:

●

RFC 1490 for HDLC, LLC2, IP, IPX over frame relay

●

Line speeds up to 2.048 M bps

●

Voice over fram e relay

●

LMI, Annex D link management

●

Annex F segmentation and re-a ssem bly

●

Bandwidth allocatio n

●

Connection priori tiz ation

●

In coming and outgoing rate control (CIR )

●

Virtual circuit backup for single or multiple PVCs/DLCIs , including bandw idth
allocation on backup circuits

DLCI Sharing

Each log ical connection on a physi cal frame relay port is assigned a Data Link Con­nection Iden tifi er (DLCI), whic h identif ies a point-to-po int connectio n, as shown in
the foll owing example. ( The numbers represent DL CIs.)

31 20 20 16 16

25

Multiple protoc ols can be pas sed over a sing le physical frame relay port by sharing a
DLCI. E ach node supp orts up to 976 use r-conf igurab le D LCIs . (Several mo re are sup­ported, but are reserved for internal use.)

Frame Relay Backup

Frame relay virtual- ci rcuit backu p in the SmartSwitc h 1800 provides frame relay
DLCIs with automatic backup protection in the event of LMI loss or port failure. (A
DLCI is co ns ider ed down/inactive if le vel 1 is down. If LMI is u sed, the DLCI is also
considered inactive if not reported as active in a Full S tat us Message from the DC E.)

A physi cal frame r el ay por t can be dedic ated to providi ng backup DLC Is , or bac kups
can co-exist with "regular" DLCIs on a port.

In a backup c onfiguration, one end is considered the "initiating" node and the other the
"remote" node. The initiating end is the one that will esta blish the backup link if it dis­covers that the primary link is down. ( A node can be the initiatin g n ode for some
backup configurations and the remote node for others.)

DLCIs used for back up on the initiating node are assigned to "backup groups," each
of which can contain up to ten backup DLC Is. A backup group is then assig ned to one
or more "pr imary" DLCIs (the ones that will be back ed up).

The basic procedure for configuring back up DLCIs is:

1. Configure all DLCIs that will be backed up or used as backup s. All parameters
can be config ure d fo r each DLCI exc ept speci f ying a
primary DL CI (that will be backed up) on an "initiating" node (which will initiate
the switchover to a backup DLCI).

An y sessions in progress when a primary DLCI goes down will not be
transferred directly to the backup DLCI, but will be reset, then established
on the backup.

Backup Group Number

on a

2. Configure backup groups. A backup group is one or more DLCIs that will act as
backup if the primary goes d own.

3. Configure

Backup Group Number

s and rela ted info rmation for prim a ry DLCIs.

This will assign a Backup Group to each primary DLCI.

For each example in Fi gu re 7- 1, assume that Node 1 is a remote site and Node 2 is a
central site. Also assume that Node 1 will be the initi ating node. On tha t node, the
pr ima ry DLCI is on p ort 2 and the backup is on port 0.

Require d Configuration

To run frame relay in a SmartSwitch 1800, make sure the following are properly con­figured:

●

Node parame t ers (Chapter 4). This is general configuration that must be done

no matter which protocols will be run in the node.

●

L oa d e d pro t ocols (Chapter 5): frame relay and any oth ers tha t will be trans -

mitted over the frame rela y link.

●

Frame Relay Bandwidth Allocation Groups (page 7-6), if configuring multiple

pr otocol s to run ove r a fra me rel ay port.

●

Frame rel ay po rt(s ) (page 7-9) that will connec t to the user dev ice(s ), netwo rk,

and/or PVC(s).

●

PVC connections (page 7-20) which define "permanent" circuits between

physical ports in the node.

●

Configuring Bandwidth Allocation Groups

T o op timize fr ame relay bandw idth use, vario us typ es of inter faces can be assig ned to
one of sixteen bandwidth allocation groups, each defined by the parameters listed in

T a bl e 7-1 (on page 7-7). Bandwidt h allocat ion groups can e nsure t hat res ponse ti me-

sensitive traffic gets access to the avai lable frame relay bandwidth.
Each of the following entiti es that use a frame relay port can be assigne d (in the

database records ) to a bandwidth allocation group:

●

Node (fo r use i n se ssion s with a NetV i e w ho st )

●

L ogical port

●

SNA Port (LLC 2 parameters)

●

IP interface

●

IPX interface

●

LLC 2 host

●

LLC2 interface

●

Bri dge por t

For further control, bandwidth allocation can b e enabled or disabled on each f rame
r e la y po r t.

This feature is app lied only when a line's available bandwidth is limited
(i.e., packets must be queued before transmission).

Als o note that bandwidt h allocatio n is not applied in a frame rela y
pa ssthroug h conf igu ration (frame r ela y PVCs into and out of the Smart­Switch , interna l PV C between the two frame relay ports). (Althou gh the
Sma rt Switc h supports ban dwid th allocatio n, routers and FRADs that ini­ti ate frame re lay pa ssthrough do not.)

Be sure you fully understand the needs of the users of the node
before assigning allocation groups; this feature can show adverse
effects if configured incorrectly.

Be sure to configure the same bandwidth allocation values at
both ends of a connection between SmartSwitch 1800s.

is a percentage of bandwidth tha t will be de dicated to traffic in a gro up if necessary.
If the traffic does not require the full allocation, unused bandwidth will be ava ilable to

The total percentage assigned to all sixteen groups can be greater th an 100%. This
allo ws allocatin g 100% to, for example, four or five groups that will be used for a par­ticular type of t raffic, and 100% to another few groups, and so on. Since usage obvi­ously cannot exceed 10 0%, any allocation of greater than 100% will be tr eated as
100%, with the percentages ass igned to the affected groups treated as relative p er­centages. Fo r example, assume that Group 1 is assigned 60%, Group 2 is assigned

If a primary DLCI is brought down, then deleted from the

database while the backup is operational, end-to-end connec­tivity over the backup will fail. For this reason, a primary DLCI
should never be deleted. (If there is a need to delete the DLCI, it

backup situation.)

used, the maximum speed is 19.2K. (The EIA standard for RS-232

Maximum Bytes per Frame

specifies the maximum size of any I-fra me (Information frame) that can be trans mitted

Logical DCE

defines the port as (if Y) logic al D CE or (i f N) DTE. The port must be configured as

Introduction

Chapter 8

Configuring X.25

A SmartSwitch 1800 X.25 port can connect to an X.25 DTE or an X.25 network. This
allow s the node to transmit X.25 traffic, as well as IP and IPX (encapsulated per RFC

1356), and SNA (per QLLC).
X.25 support in the SmartSwitc h 1 800 includes:

●

Full compliance wi th CCITT Recommenda tion X .25

●

Line speeds up to 2.048 M bps

●

Full X.121 addressin g capabil ity

●

Ad dres s tr anslatio n

●

RFC 1356 for IP over X.25

●

RFC 1490 encapsulation (HDLC)

The SmartSwitch 1800 also suppo r ts logical X.25 por ts, which all ow multiple legacy
protoco ls (SDLC, asy nc, bisync, etc.) to be encapsulated via X.25 and transmitted
over a singl e physical frame relay port. A SmartSwitch 1800 can contai n u p to 56
logica l port s, a l l on one physical port or s pread over s everal physical por ts.

Some t hings t o know about l ogical ports are:

●

En capsulat ion can be via e it her T1.617 Anne x G or T1.617 RFC1490. You
sh ould k now the p ros and cons of us ing each . The ex plan ation of "E ncapsulation

Method" on page 8-16 offers some help.

●

Bot h leve l-2 and le vel-3 w indows can be confi gure d. (Configura ti on and ope r­ation is the same for either encapsula tion method.)

Require d Configuration

To run a physical port as X.25, make sure t he following are properly configured:

●

Node parame t ers (Chapter 4). This is general configuration that must be done

no matter which protocols will be run in the node.

●

Loaded protocols (Cha pter 5): X.25 and any others that will be transmitted over

the X.25 link.

●

X.25 port(s) tha t will connect to the user device(s) and network. See pa ge 8-2.

●

SVC Subscriber ID(s) (page 8-21), which identifiy user devices to each o ther

and the SmartSwitch 1800.

Before configuring a lo gical X.2 5 port, m ake sure these are p roperly configured:

●

Protocol(s) (C hap ter 5) that will be transmitted over the logical port.

●

Physical frame relay port (Chapter 7) on which the logical port wi ll reside .
