LUCENT TECHNOLOGIES END-USER LICENSE AGREEMENT

LUCENT TECHNOLOGIES IS WILLING TO LICENSE THE ENCLOSED SOFTWARE
AND ACCOMPANYING USER DOCUMENTATION (COLLECTIVELY, THE
“PROGRAM”) TO YOU ONLY UPON THE CONDITION THAT YOU ACCEPT ALL OF
THE TERMS AND CONDITIONS OF THIS LICENSE AGREEMENT. PLEASE READ
THE TERMS AND CONDITIONS OF THIS LICENSE AGREEMENT CAREFULLY
BEFORE OPENING THE PACKAGE(S) OR USING THE LUCENT SWITCH(ES)
CONTAINING THE SOFTWARE, AND BEFORE USING THE ACCOMPANYING USER

THE PROGRAM WITHIN TEN (10) DAYS FROM SHIPMENT TO THE PLACE FROM
WHICH IT WAS ACQUIRED, AND YOUR LICENSE FEE WILL BE REFUNDED. THIS
LICENSE AGREEMENT REPRESENTS THE ENTIRE AGREEMENT CONCERNING
THE PROGRAM BETWEEN YOU AND LUCENT, AND IT SUPERSEDES ANY PRIOR
PROPOSAL, REPRESENTATION OR UNDERSTANDING BETWEEN THE PARTIES.

1. License Grant. Lucent hereby grants to you, and you accept, a non-exclusive,

non-transferable license to use the computer software, including all patches, error
corrections, updates and revisions thereto in machine-readable, object code form only

granted under this License Agreement.

4. Term. This License Agreement is effectiv e upon your opening of the package(s) or

use of the switch(es) containing Software and shall continue until terminated. You
may terminate this License Agreement at any time by returning the Program and all
copies or portions thereof to Lucent. Lucent may terminate this License Agreement
upon the breach by you of any term hereof. Upon such termination by Lucent, you
agree to return to Lucent the Program and all copies or portions thereof. Termination
of this License Agreement shall not prejudice Lucent's rights to damages or any other
available remedy.

5. Limited Warranty. Lucent warrants, for your benefit alone, for a period of 90

days from the date of shipment of the Program by Lucent (the “Warranty Period”) that
the program diskettes in which the Software is contained are free from defects in
material and workmanship. Lucent further warrants, for your benef it alone, that during
the Warranty Period the Program shall operate substantially in accordance with the
User Documentation. If during the Warranty Period, a defect in the Program appears,
you may return the Program to the party from which the Program was acquired for
either replacement or, if so elected by such party, refund of amounts paid by you under
this License Agreement. You agree that the foregoing constitutes your sole and
exclusive remedy for breach by Lucent of any warranties made under this Agreement.

EXCEPT FOR THE WARRANTIES SET FORTH ABOVE, THE PROGRAM IS LICENSED
“AS IS”, AND LUCENT DISCLAIMS ANY AND ALL OTHER WARRANTIES,
WHETHER EXPRESS, IMPLIED OR STATUTORY, INCLUDING, WITHOUT
LIMITATION, ANY IMPLIED WARRANTIES OF MERCHANTABILITY OR FITNESS
FOR A PARTICULAR PURPOSE AND ANY WARRANTIES OF NONINFRINGEMENT.

6. Limitation of Liability. Lucent’s cumulative liability to you or any other party

for any loss or damages resulting from any claims, demands, or actions arising out of
or relating to this License Agreement shall not exceed the greater of: (i) ten thousand
US dollars ($10,000) or (ii) the total license fee paid to Lucent for the use of the

7. Proprietary Rights Indemnification. Lucent shall at its expense defend you

against and, subject to the limitations set forth elsewhere herein, pay all costs and
damages made in settlement or awarded against you resulting from a claim that the
Program as supplied by Lucent infringes a United States copyright or a United States
patent, or misappropriates a United States trade secret, provided that you: (a) provide
prompt written notice of any such claim, (b) allow Lucent to direct the defense and
settlement of the claim, and (c) provide Lucent with the authority, information, and
assistance that Lucent deems reasonably necessary for the defense and settlement of
the claim. You shall not consent to any judgment or decree or do any other act in
compromise of any such claim without first obtaining Lucent’s written consent. In any
action based on such a claim, Lucent may, at its sole option, either: (1) obtain for you
the right to continue using the Program, (2) replace or modify the Program to avoid
the claim, or (3) if neither (1) nor (2) can reasonably be effected by Lucent, terminate
the license granted hereunder and give you a prorata refun d of th e license fee paid for
such Program, calculated on the basis of straight-line depreciation over a five-year
useful life. Notwithstanding the preceding sentence, Lucent will have no liability for
any infringement or misappropriation claim of any kind if such claim is based on: (i)
the use of other than the current unaltered release of the Program and Lucent has
provided or offers to provide such release to you for its then current license fee, or (ii)
use or combination of the Program with programs or data not supplied or approv ed b y
Lucent to the extent such use or combination caused the claim.

8. Export Control. You agree not to export or disclose to anyone except a United

States national any portion of the Program supplied by Lucent without first obtaining
the required permits or licenses to do so from the US Office of Export Administration,
and any other appropriate government agency.

9. Governing Law. This License Agreement shall be construed and governed in

accordance with the laws and under the jurisdiction of the Commonwealth of
Massachusetts, USA. Any dispute arising out of this Agreement shall be referred to an
arbitration proceeding in Boston, Massachusetts, USA by the American Arbitration
Association.

10. Miscellaneous. If any action is brought by either party to this License

Agreement against the other party regarding the subject matter hereof, the prevailing
party shall be entitled to recover, in addition to any other relief granted, reasonable
attorneys’ fees and expenses of arbitration. Should any term of this License
Agreement be declared void or unenforceable by any court of competent jurisdiction,
such declaration shall have no effect on the remaining terms hereof. The failure of
either party to enforce any rights granted hereunder or to take action against the other
party in the event of any breach hereunder shall not be deemed a waiver by that party
as to subsequent enforcement of rights or subsequent actions in the event of future
breaches.

information on configuring the logical port options you need if you plan to use
SVCs in your network.

CBX 500 frame-based modules. Note that since the B-STDX 9000 is not a true
ATM switch, many of the parameters you need to configure for the various ATM
logical port types are different from the CBX or GX; in addition, the
B-STDX 9000 does not provide ATM features for signaling and SVCs. These
same ATM exceptions exist for the CBX 500 frame-based modules.

Overview

ATM FCP

ATM FCP

Beta Draft Confidential

Chapter 5 provides information about the CBX 500 ATM Flow Control Processor

(FCP), which supports ATM traffic management through binary, hop-by-hop,
closed-loop flow control algorithms that shift network congestion to the edge of the
network. In addition, the CBX 500 ATM FCP uses several per-virtual circuit (VC)
cell/packet queuing and discarding mechanisms for additional network congestion
control.

Based on the ATM Forum’s Traffic Management Specification, Version 4.0, the ATM
FCP delivers a fair, deterministic service for bursty ATM traffic, including:

• Dynamically adjusting the allowed cell rate (ACR) in response to resource
management (RM) cell feedback

• Reducing congestion in the network by adjusting the data rate at which a VC
sends cells fair resource allocation based on the minimum cell rate (MCR)

• Per VC-queuing with early packet discard/partial packet discard (EPD/PPD)
capability.

Chapter 6 provides step-by-step instructions for configuring the ATM FCP as well as

answers to frequently-asked questions (FAQs) about working with the ATM FCP.

Note – Contact a qualified Lucent organization for network design validation before
enabling the FCP.

ATM Trunks

Chapter 7 describes how to configure the following types of ATM trunks:

• ATM Direct Trunks

• ATM OPTimum (Cell) Trunks

• ATM OPTimum Frame Trunks (B-STDX 9000 only)

For information on each of these trunk types, revie w the trunk logical port descriptions
in Chapter 2 and Chapter 4. Chapter 7 also describes how to configure external trunks
and provides instructions for using trunk backup and Fast APS.

Network-wide Features

The following chapters explain ho w to configure features that you can use throughout
your ATM network.

• Chapter 12 describes how the CBX 3500, CBX 500, and GX 550 use traffic
descriptors to define a service contract that guarantees that a specified amount of
data is delivered. You configure a set of traffic descriptors that you can use when
you define PVCs throughout your ATM network; this configurable control circuit
feature enables you to ensure Quality of Service (QoS). Note that ATM services
for a B-STDX 9000 switch, CBX 500 frame-based modules, and 4-port ethernet
modules do not use traffic descriptors.

• Chapter 13 describes a Layer2 Virtual Private Network (VPN) which is an
optional software feature that enables network providers to dedicate resources for
those customers who require guaranteed performance, reliability , and pri vac y. Use
the instructions in this chapter to configure Layer2 VPN services.

Overview

Fault-tolerant PVCs

Fault-tolerant PVCs

Chapter 14 describes an optional logical port feature called fault-tolerant PVC

(sometimes referred to as resilient UNI/NNI). A fault-tolerant PVC configuration
enables a UNI data communications equipment (DCE) or data terminal equipment
(DTE) logical port to serve as a backup for any number of active UNI ports. If a
primary port fails or if you need to take a primary port offline for maintenance, you
activate the backup port.

Using this feature, a logical port is given a service name. When you configure a PVC,
select this service name as the logical port endpoint. If you activate the backup port,
all PVCs on the failed primary port are automatically rerouted.

Note – You should not configure SVCs on a logical port that is also designated as a
backup port.

If you use resilient UNI features in conjunction with the Automatic Protection
Switching (APS) functions available on the CBX 3500, CBX 500 and GX 550 optical
modules, you can configure a PVC to automatically revert to the backup port if the
primary port fails.

RLMI

SVCs

Chapter 15 describes the Frame Relay Resilient Link Management Interface (RLMI)

feature and how to configure RLMI on ATM Network Interworking for Frame Relay
NNI logical ports on ATM IWU and ATM CS cards.

RLMI provides resiliency by monitoring Link Management Interface (LMI) link
status. RLMI enables a pair of Frame Relay UNI, NNI, or ATM Network Interworking
for Frame Relay NNI logical ports configured on a B-STDX 9000, CBX 3500, or
CBX 500 switch to serve as preferred and backup ports. If the primary port fails, a
switchover to the backup port occurs.

The CBX 3500, CBX 500, and GX 550 offer switched virtual circuit (SVC) features.
With SVCs, connections are not predefined as the y are for PVCs. Instead, end stations
use a signaling protocol to indicate to the ATM network the endpoint to which it
routes the SVC request. To support SVC services, each user endpoint is assigned a
unique address that identifies the endpoint and enables the network to route the SVC
request.

The following chapters describe basic SVC concepts and configuration:

• Chapter 16 provides an overview of SVC concepts. Read this chapter if you are
unfamiliar with SVC address formats and registration or need more information
on route determination or address translation. This chapter also describes how to
use network ID addressing.

• Chapter 17 describes how to configure SVC node and port prefixes and port
addresses for each SVC address format. This chapter includes information on
configuring network identifier addressing.

The following sections describe optional SVC features you can use in your network to
take advantage of ATM signaling functions.

SVC Proxy Signaling

Chapter 17 describes SVC proxy signaling. SVC proxy signaling is an optional

feature for the CBX 3500, CBX 500 and GX 550 switches that enables a single
signaling entity to signal on behalf of multiple endpoints. You can use proxy signaling
to allow end systems that do not understand ATM signaling to set up SVCs via a proxy
signaling agent (PSA). The PSA performs all signaling functions on behalf of the end
system, known as the proxy signaling client (PSC).

Overview

SVCs

SPVCs

Chapter 18 describes soft permanent virtual circuits (SPVCs), also called Offnet

Circuits. The network uses signaling to establish an SPVC. The NMS provisions one
end of the SPVC with the address identifying the egress interface from the network.
Once the SPVC configuration is in place, the switch at one end of the SPVC initiates
the signaling. This calling end is responsible for establishing, releasing, and
re-establishing the SVC request.

CUGs

Chapter 19 describes closed user groups (CUGs). You can use CUGs to divide all

SVC network users into logically linked groups of users. Members of the same CUG
have particular calling privileges that members of different CUGs may not have.
CUGs form one level of security between users of a network, allowing only those
users who are members of the CUG to set up calls to each other. Information about
CUG membership and rules is available throughout the network.

Port Security Screening

Chapter 20 describes Port Security Screening. This feature is a mechanism you can

use to ensure that the network cannot be compromised by unauthorized SVC access.
You do this by creating screens that can allow/disallow incoming and outgoing SVCs.

Beta Draft Confidential

Chapter 21 describes how to configure the ATM Private Network-to-Network

Interface (PNNI) routing protocol in your Lucent network. Table 21-1 on page 21-2
lists the supported PNNI features included in this release.

PNNI is a standard designed by the ATM Forum. This standard defines both an ATM
routing protocol and an ATM signaling protocol. Lucent supports PNNI on the CBX
3500, CBX 500, and GX 550 switch platforms. For a detailed explanation of PNNI
routing, see the ATM Forum T ec hnical Committee Private Network-Network Interface
Specification Version 1.0 (af-pnni-0055.000), available from the ATM Forum’s web
site:

http://www.atmforum.com.

Appendix A describes how to tune the Lucent Call Master Connection Admission

Control (CAC) to achieve a desired cell loss ratio objectiv e across all physical ports in
your network. The Lucent CAC is responsible for the bandwidth allocation on all
ATM cards on the CBX 3500, CBX 500, GX 550, and B-STDX 9000. It is also
responsible for bandwidth allocation on all frame cards with the priority frame
capability.

ATM Traffic Descriptors

Appendix B describes how each traffic descriptor combination affects the cell streams

under different traff ic conditions. When you create either a PVC or a PMP circuit, you
select one of several traffic descriptor combinations. The traffic descriptor
combination specifies which traffic parameters are used for traffic control. It also
determines the number and type of cells that are admitted into a congested queue, and
whether or not high-priority cells are tagged as low-priority cells when traff ic e xceeds
the traffic parameter thresholds.

CBX 500 Shared SP Threads

Appendix C provides information on shared switch processor (SP) threads. CBX 500

chassis slots 3-4, 5-6, 7-8, 9-1, 10-2, 11-12, 13-14, and 15-16 ar e associated with the
SP threads. This means that if you have an input/output module (IOM) installed in
slots 3 and 4, you are “sharing” an SP thread. If you have an IOM in slot 9 or 10, you
are sharing a thread with the SP itself. In this case, there are no thread limitations; the
IOM has the full 599.040 Mbps of bandwidth available.

FCP Rate Profile Tables

Appendix D describes ATM Flow Control Processor (FCP) rate profile tables,

including organization and def ault val ues. You can provision FCP rate profile tables in
four separate files. You then use Navis EMS-CBGX to download these files to the
ATM FCP.

Priority Routing

Appendix E details priority routing, which enables you to prioritize permanent and

switched virtual circuits (PVCs and SVCs) in your network. Priority routing can
provide the following advantages: higher up time for high-priority circuits; optimal
paths for high-priority circuits; and higher capacity to burst past the guaranteed QoS
rates for high-priority circuits. The switch treats priority routing, QoS class, and
circuit priority as independent elements. Priority routing rules are used for connection
setup. QoS class is applied after the connection is set up. Circuit priority rules are
applied once QoS class is established. Keep in mind that you must assign a higher
priority to real-time QoS classes.

Overview

FCP Rate Profile Tables

Reliable Scalable Circuit

Appendix F lists the Network Management Station (NMS) Simple Network

Management Protocol (SNMP) set errors that can occur during Circuit Add, Modify,
and Delete operations for standard and redirect permanent virtual circuits (PVCs).
When you perform these operations, the errors and, when possible, the circuit end
point that caused the error are reported to you. When an error occurs, the Abort, Retry,
and Ignore options are sensitive to the endpoint that caused the failure.

OSPF Name Aggregation

Appendix G provides guidelines for using Open Shortest Path First (OSPF) name

aggregation to minimize memory consumption when you provision prefixes and
addresses for ATM SVC/SPVC or Frame Relay SVC connections across Lucent
network switches.

Customer Names

Appendix H describes Customer Names, an optional software feature that enables

network providers to assign ATM logical ports to a specific customer so that they can
then use the customer name as a filter when viewing logical ports. You can configure
the Customer Names feature with or without the use of Virtual Private Network
(VPN).

ATM UNI DCE and DTE

This section describes some of the concepts you need to know when defining ATM
UNI DCE and ATM UNI DTE logical ports for CBX 3500, CBX 500, and GX 550
switches. You can configure a single ATM UNI logical port on a physical port to
support the following standard protocol functions:

• ATM UNI 3.0, 3.1, and 4.0 (see “ATM UNI 4.0 Support” on page 2-4 for more
information)

• International Telecommunications Union (ITU) UNI

• Interim Inter-switch Signaling Protocol (IISP) 3.0 and 3.1

You us e the ATM UNI DCE logical port type to communicate with most ATM CPE.
An ATM UNI DCE logical port represents the “network side” equipment. This logical
port supports all types of PVCs as well as SVCs. For SVC applications, the ATM UNI
DCE logical port assumes the role of the network side of the UNI signaling interface.

You can also use the ATM UNI DCE as a feeder port for Lucent OPTimum trunks or
virtual UNIs. When used as a feeder port, you can still use the ATM UNI DCE logical
port for PVC and SVC applications.

The ATM UNI DTE logical port type has the identical functionality of the ATM UNI
DCE logical port with one exception. For SVC applications, the ATM UNI DTE
assumes the role of the “user side” of the UNI signaling interface.

Using ILMI

Interim Local Management Interface (ILMI) is a Management Information Base
(MIB) that provides status and communication information to ATM UNI devices. This
information includes status and statistics for virtual paths, connections, and address
registration. The CBX 3500, CBX 500, GX 550, and B-STDX 9000 switches support
the ILMI MIB.

If you want to use ILMI, make sure both endpoints of the UNI connection support this
MIB. When you enable ILMI on an ATM UNI DCE logical port, the switch polls the
attached device every five seconds. Five seconds is the polling period. If no response
is received after four consecutiv e polls (loss threshold), the switch considers the ILMI
state to be down.

If you intend to use ILMI on the logical port (and the attached device supports ILMI),
Lucent recommends that you enable ILMI support before you provision circuits.
Under certain conditions, enabling ILMI after you provision circuits on a logical port
may cause negative bandwidth with the associated QoS classes (including constant bit
rate [CBR]).

About ATM Logical Ports

ATM UNI Concepts

Note – If you enable ILMI on a logical port, and for some reason the ILMI state is
down, the logical port does not go down.

ILMI VCC Trap Support

CBX 3500, CBX 500, GX 550, and B-STDX 9000 switches can receive ILMI traps
that report VCC status from ATM UNI 3.1 end system devices. If a Lucent switch
receives an ILMI trap indicating a change in PVC status, the information is
transmitted over one or more Lucent switches to the PVC endpoint at a remote ATM
UNI 3.1 device. This is handled differently, depending on whether the remote
interface is Frame Relay or ATM:

• If the remote interface is Frame Relay, the PVC status change (inactive or active)
is transmitted by Frame Relay to ATM Service Interworking to the remote
interface, and is reported by LMI protocol to the remote circuit endpoint.

• If the remote interface is ATM, the PVC status change is reported to the remote
circuit endpoint by presence of (inactive) or absence of (active) virtual channel
level (F5) OAM alarm indication signal (AIS).

To receive ILMI traps from ATM UNI 3.1 devices, you must enable ILMI on the
ILMI/OAM tab in the Add Logical Port dialog box. For information about enabling
ILMI for logical ports, see Chapter 3, “Configuring CBX or GX Logical Ports,” and

Chapter 4, “Configuring ATM Logical Ports on Frame-based Modules.”

Using Logical Port Signaling

This section describes the default signaling tuning parameters for an ATM UNI logical
port.

Note – ATM logical ports on B-STDX 9000 modules or CBX 500 frame-based
modules do not support signaling.

In an ATM network, signaling is responsible for establishing and releasing SVCs.
Signaling is used only on ingress and egress ports, including user-to-network,
network-to-user, and network-to-network ports.

On ATM UNI DTE or ATM UNI DCE logical ports, if you change the default values
and later change the UNI version for the port, the Network Management Station
(NMS) prompts you to overwrite current settings with the default tuning parameters
for the new UNI version. If you intend to use signaling on the logical port (and the
attached device supports signaling), Lucent recommends that you set the logical port
signaling options before you provision circuits. Under certain conditions, enabling
signaling after you provision circuits on a logical port may cause negative bandwidth
with the associated QoS classes (including CBR).

Beta Draft Confidential

ILMI and Signaling Example

Under certain conditions, enabling ILMI and/or signaling after you provision circuits
on a logical port may cause negative bandwidth for the associated QoS classes.

For example, you create an ATM logical port with both ILMI and signaling disabled.
You then create a full-bandwidth CBR circuit (PCR = 96000 cps) on this logical port.
If you later enable ILMI and/or signaling on the logical port, the bandwidth now
appears to be negative. The circuit will no longer come back up due to insufficient
bandwidth if you modify the logical port admin status or circuit.

Configurable Control Circuits

The configurable control circuit feature enables you to configure forward and reverse
traffic descriptors (TDs) on CBX 3500, CBX 500, and GX 550 switches for the
following:

• ATM UNI ILMI and signaling control channels

About ATM Logical Ports

ATM UNI Concepts

• ATM Direct and OPTimum trunk signaling and node-to-node management traffic

The switch software views a control circuit as a VCL between the logical port and the
internal switch processor. When you configure a control circuit, the switch creates a
VCL between this port and the switch processor. The logical port uses the forw ard TD
to police traffic flowing into the switch (UNI ILMI and signaling control channels
only). It uses the backward TD to determine the service category and equivalent
bandwidth for the control circuit. The backward TD is also used to calculate the
effectiv e bandwidth of the circuit to be used for bandwidth management on the logical
port.

For control channels between a Lucent switch and another vendor device (including
the ILMI, UNI signaling, and PNNI routing control channels), the TD v alues calculate
both the amount of bandwidth reserved by Call Admission Control (CAC) and the rate
at which the control channels are policed.

Control channels are not policed by default. When you enable the usage parameter
control (UPC) or network parameter control (NPC) for the particular logical port, the
control channel is policed at the TD rate. Similar to the trunk control channels, the TD
values associated with the ILMI, UNI signaling, and PNNI routing control channels
do not affect the traffic shaping rate.

For more information about TDs, see Chapter 12, “Configuring ATM Traffic

Descriptors.”

ATM OPTimum Cell Trunk

ATM OPTimum Cell Trunk

The CBX 3500, CBX 500, GX 550, and B-STDX 9000 ATM OPTimum cell trunk
carries all types of PVC, SVC, and management data. The ATM OPTimum trunk
logical port type provides trunk connecti vity between two Lucent switches that are no t
directly connected. In this application, some other network elements are separating the
two Lucent switches. These network elements usually consist of ATM switches in
another network. The network provider who manages the other ATM switches
provisions a virtual path connection (VPC) to carry the Lucent trunk traff ic. This VPC
supports the trunk and carries all the associated trunk protocol, manage ment data,
PVCs, and SVCs between the two Lucent switches (see “Configuring the VPI”
below).

Before you can configure an ATM OPTimum trunk logical port, you must first
configure an ATM UNI or NNI logical port with a minimal amount of bandwidth; this
logical port acts as the feeder port. The feeder port serves the following purposes:

• Enables interoperability between Lucent and non-Lucent switches by providing a
standard interface type over which a link management protocol can run

Beta Draft Confidential

• Controls the valid range of virtual path identifier/virtual channel identifier
(VPI/VCI) values that you can use

Using switch software release 3.0 or greater on the CBX 500 switch, 9.2 or greater for
the CBX 3500 switch, and 1.0 or greater on the GX 550 switch enables VPCs to
traverse OPT imum trunks. This capability depends on the logical port conf iguration as
well as the configuration of the interfacing network. Prior to this release, VPCs could
not traverse OPTimum trunks.

Configuring the VPI

The VPI is the identifier used for all VCC circuits routed over the OPTimum trunk.
The range of valid VPI and VCI values depends upon the number of valid VPI bits
you set for the ATM UNI feeder port (see Table 2-3 on page 2-14). Enter a number
from 0-nnnn to identify the VP for the ATM logical port; nnnn is equal to 2
P is the value specified in the Valid Bits in VPI field for the UNI feeder port that
shares this physical port (see the example on page 2-13).

For example, if you entered 4 in the Valid Bits in VPI field for the UNI feeder port,
you can have up to 15 virtual paths on this port (2
Bits in VPI field, you can have up to 255 virtual paths on this port (2
highest value you can enter (and therefore, the greatest number of VPs you can
configure on the port) depends on the value you entered in the Valid Bits in VPI field
for the ATM UNI feeder port. The OPTimum trunk’s VPI must be unique

Configuring the OPTimum Trunk for VPCs

PVC and SVC VPCs and Internet Protocol (IP)-related connections can traverse
OPTimum trunks. The following section describes each configuration.

PVC/SVC VPC Connections

The VPC VPI start and VPC VPI stop values define the range of VPIs to be used for
all connection-based VPC circuits (that is, PVC, SVC, and SPVC) over this
OPTimum trunk.

The valid range of VPI v alues depends on the number of v alid VPI bits you set for the
AT M UNI feeder port (see Table 2-3 on page 2-14). The specified range may not
overlap the ranges specified for OPTimum trunk IP connections.

Example

Assume that the following conditions are in place:

About ATM Logical Ports

ATM OPTimum Cell Trunk

• The number of valid VPI bits set from the ATM UNI feeder port is 4.

• The VPI value is set to 0.

Using these assumptions, if you want to configure t wo VPIs on the OPT imum trunk to
support PVC, SVC, or SPVC VPC circuits, you could specify a VPC VPI start of 1
and a VPC VCI stop of 2.

Note – The network that interfaces with the OPTimum trunk must be configured to
accept circuits with this VPI and any of its valid VCIs. To accomplish this, create a
PVC in the interfacing network using this VPI and define the PVC circuit type as VPC
(see Table 10-3 on page 10-17).

IP-related Connections

You can configure label switch paths (LSPs) over OPTimum cell trunks on
B-STDX 9000, CBX 3500, and CBX 500 switches. This is done differently,
depending on the switch:

• On CBX 3500 and CBX 500 switches, IP automatically assigns a permanent
virtual path (PVP) to each LSP crossing an OPTimum trunk. Th ese point-to-point
PVPs carry LSP traffic in both directions, which reduces the number of paths
required to interconnect switches in two given clusters.

• On B-STDX 9000 switches, IP assigns a VCC to each LSP crossing an OPTimum
trunk.

• GX 550 ES DS3 CE Transport card physical port

You can configure one ATM CE logical port on each DS3 physical port. The ATM CE
logical port can be used as a PVC endpoint.

The AT M CE physical port, logical port, and circuit are used to provide an
unstructured DS3 service that emulates a point-to-point DS3 circuit configuration.
The CE service enables two devices to transparently pass a DS3 bitstream through an
ATM network, so that the two devices appear to be directly connected to each other.
The ATM network, in effect, is the wire used to pass the bitstream from one device to
the other.

ATM NNI

The CBX 3500, CBX 500, and GX 550 ATM NNI logical port type enables you to

ATM NNI

A virtual UNI/NNI forms an extension of the standard “direct” UNI DCE/DTE or NNI
logical port types. In an ATM network, you can use virtual UNI/NNI logical ports to
enable VP tunneling or to connect to a VP multiplexer. VP tunneling allows you to
connect two switches (using signaling) via a virtual path through the ATM network
(network-to-network connection class). See the example in Figure 2-1.

VP multiplexing enables you to connect a CBX 3500, CBX 500, or GX 550 switch to
a VP multiplexer using a direct UNI (or NNI) logical port on which you have
configured sev eral “virtual” UNI (or NNI) ports. The VPI address range you define for
each virtual UNI/NNI port corresponds to a port on the VP multiplexer. This method
does not use VPCs and the configur ed logical port bandwidth can be used b y any PVC

T o establish connections, ATM uses virtual channels (VCs) and virtual paths (VPs). A
VC is a connection between two communicating ATM entities. It may consist of a
group of several ATM links, CPE to central office switch, and
switch-to-switch or switch-to-user equipment. All communications proceed along this
same VC, which preserves call sequence and provides a certain level of QoS.

A VP is a group of VCs carried between two points. VPs provide a way to bundle
traffic headed in the same direction.

VPIs and VCIs are hardware addressing identifiers (similar to Frame Relay’s Data
Link Connection Identifier [DLCI]) that route cell traffic. The ATM cell header
contains both a VPI and a VCI, which gives an ATM cell a unique VCI and associates
it with a particular VP. Every ATM cell uses these VP/VC identifiers.

Switching equipment checks the VPI portion of the header to route traf f ic o v er certain
trunks. It uses the VCI portion of the address to deliver the cell to an individual user
within that destination.

Setting the Number of Valid Bits in the VPI/VCI

The Number of Valid Bits setting applies to the VPI and VCI range that you can use
for VCCs (both PVCs and SVCs). The default values of VPI = 4 and VCI = 10 mean
that you can use VCCs over the range of VPI = 0 – 15 (4 bits of VPI) and a VCI range
of VCI = 32 – 1023 (10 bits of VCI). The values have no effect on VPCs, which you
can provision anywhere over the VPI = 0 – 255 range; you can provision VPCs over
the VPI = 0 – 4095 range if you use the NNI cell header format.

For the CBX 3500 and CBX 500, the valid range for the VPI field is 0 – 8 and the
valid range for the VCI field is 6 – 14; for the GX 550, the v alid range of the VP I fi eld
is 0 – 12 and the VCI field is 6 – 13. You may have to adjust these values in the
following situations:

• In cases where the required VPI/VCI(s) of the attached devices are outside the
range that the default values provide (VPI = 0 – 15 and VCI 32 – 1023).

• If you use this logical port as a feeder for OPTimum trunks or virtual UNIs, the
VPI value limits the number of OPTimum trunks you can create on this physical
port. The VCI value limits the number of circuits you can route over each
OPTimum trunk.

For example, if you set the VPI value to 3 and the VCI value to 11, you can have
up to 7 virtual paths on the port, and up to 2,016 virtual channels on each path.

Note – On a CBX 500 only, P+C ≤ 14.

VPI/VCI Bit Allocation

When configuring a Direct Trunk or UNI logical port on a CBX 3500, CBX 500, or
GX 550, you select the number of bits in the Number of Valid bits in VPI/VCI field.
The highest order bit set (1) is used for reserving address space for
Multipoint-to-Point Tunnel (MPTs). It does not matter what the bit allocation for
VPI/VCI is, a set portion of the bit is used for establishing 16 MPTs across a trunk.
The number of bits configured for VPI will directly affect the total number of transit
VCs.

VPs and VCs

The total number of VCCs, MPTs, and VPCs supported varies because of dynamic
address allocation; however, the maximum number supported is 15360 VCCs/VPCs
and 1024 MPTs. With dynamic address allocation, VPI bits are no longer dedicated
for use with VPCs.

Use Table 2-3 as a guide to set the VPI/VCI values on a CBX 500 or CBX 3500. Use

Table 2-4 as a guide to se t the VPI/VCI values on a GX 550.

Note – When you configure an OPTimum trunk or virtual UNI between two endpoints,
the logical ports must match the VPI of the VPC that provides the connectivity between
the two switches. The VPI range for the VPI/VCI valid bits setting for each endpoint
must accommodate this VPI.

ATMoMPLS UNI/NNI

Configuring VCC VPI Start and Stop Values for Virtual UNI/NNI

The CBX 3500, CBX 500, and GX 550 switches provide a virtual UNI/NNI feature.
The direct UNI/NNI provides the range of VCC VPI start and stop values. The range
of VPI start and stop values you define for the first virtual UNI/NNI must fall within
this range; it cannot overlap with the range you define for subsequent virtual UNI/NNI
ports.

For example:

Logical Port VPI Start VPI Stop

First Virtual UNI/NNI 2 5
Second Virtual UNI/NNI 6 10

The switch handles SVCs differently, depending on how you configure the
Connection Type field of the virtual UNI/NNI (see Table 3-4 on page 3-29). If the
logical port is set to the Network <-> Network Connection Type, it implies a network
scenario as shown in Figure 2-1 on page 2-11. In this case, the first VPI is used for
VCCs only. Additional VPIs can only be used for signaled VPCs with the best effort
QoS. If the logical port is set to the Network <=> Endsystem Connection Type, it
implies a network scenario as shown in Figure 2-2 on page 2-12. In this case, all
available VPIs can be used for either signaled VCCs or VPCs of any QoS class.

The restrictions described above only apply to SVCs. When using virtual UNI/NNIs
in conjunction with PVCs, there are no restrictions and the Connection Type field on
the logical port is not used.

ATMoMPLS UNI/NNI

The CBX 3500, CBX 500, and GX 550 ATMoMPLS UNI or NNI logical port types
enable you to configure an ATMoMPLS UNI or NNI logical port with a minimal
amount of bandwidth to act as the feeder port which enables interoperability between
Lucent and non-Lucent switches. This feeder logical port must be configured before
you can configure an ATMoMPLS trun k. For more information on ATMoMPLS UNI
and NNI LPorts, see Chapter 8, “Configuring ATM Over MPLS T r un ks.”

About Logical Port Bandwidth

The maximum amount of logical port bandwidth does not equal the physical port
bandwidth due to the overhead associated with packaging A TM cells into the physical
layer frames. This overhead is different for each physical media type as well as the
different packaging methods. Table 2-5 provides a guide to mapping and converting
physical layer bandwidth to logical port bandwidth.

In some cases, due to the way the switch stores logical port bandwidth, the NMS may
have to round down non-integer maximum logical port bandwidth values to the
nearest Kbps value.

Note – For most applications, rounding down non-integer maximum logical port
bandwidth does not cause any problems. However, if you need to run 100% line rate
traffic through a policed PVC where you have rounded values, policing may cause
minor cell loss.

About Logical Port Bandwidth

Example

If you send 100% line rate traffic over an ATM DS3 interface that uses HCS direct
mapping, the cells arrive at a rate equal t o 44209.694 Kbps or 1 04268.15 cps. Because
of NMS rounding, the maximum peak cell rate (PCR) you can provision for this PVC
is 104266. If you enable UPC on this PVC, approximately two cells every second are
lost. For these cases, you may want to either adjust the traffic rate or disable UPC for
this circuit.

Modifying Logical Port Bandwidth

You can modify logical port bandwidth on UNI and NNI logical ports even after you
configure PVCs on this port. However, if you reduce the logical port bandwidth such
that the new value is not sufficient to support all of the PVCs traversing the port, the
available band wid th en ters a negative state. The PVC remains active until it has to be
reestablished (that is, trunk reroute, IOM reboot). If at this time the logical port does
not have enough bandwidth to support the PVC, the PVC remains inactive due to
insufficient bandwidth.

CBX 500 SP Thread Bandwidth Available for Logical Ports

The NMS and CAC enforce the switch processor (SP) fabric thread bandwidth such
that each SP fabric thread is limited to 599.040 Mbps. This enforcement ensures that
service is guaranteed even when two IOMs are placed on the same SP fabric thread.
The 599.040 Mbps number is derived from the maximum user cell bandwidth that the
OC-12c/STM-4 interface supports (the OC-12c/STM-4 physical layer bandwidth is

622.080 Mbps, but the maximum user traffic that any OC-12c/STM-4 port can support
is 599.040 Mbps). This 599.040 Mbps thread limitation is also derived from the
maximum user cell bandwidth that the four OC-3c/STM-1 interfaces support (the
OC-3c/STM-1 physical layer bandwidth is 155.020 Mbps, but the maximum user
traffic that any OC-3c/STM-1 port can support is 149.76 Mbps).

For example, this NMS enforcement is noticeable whenever you attempt to provision
two OC-3c/STM-1 cards on the same SP fabric thread. As you provision logical ports,
the NMS subtracts the assigned bandwidth from the 599.040 Mbps total. After you
provision four OC-3c/STM-1 logical ports at the maximum 149.76 Mbps bandwidth
value, there is no bandwidth left for the other OC-3c/STM-1 card and its logical po rts.
Because of this, when you use two cards on the same fabric thread, Lucent
recommends you allocate the bandwidth accordingly across all of the IOM ports.

Note – You can oversubscribe the logical ports to avoid any negative implications
associated with this restriction. You can use the QoS tab (accessible from the Add
Logical Port dialog box) to oversubscribe a logical port.

About the Oversubscription Factor

The oversubscription factor percentage enables you to optimize the number of PVCs
and SVCs you can configure on the network by allowing you to oversubscribe the
logical ports. If you configure oversubscription for the VBR classes of service (CoS),
QoS is no longer guaranteed.

Note – To ensure QoS, monitor the network closely before you modify
oversubscription values to exceed the minimum value of 100%. If you adjust the
oversubscription percentage, monitor the cell-loss ratio to be sure the ne w setting does
not affect QoS.

The CAC algorit hm dete rmin e s effective bandwidth of a virtual circuit (PVC and
SVC). For a VBR circuit, the CAC uses the circuit’s PCR, SCR, and MBS values. For
CBR circuits, the CAC uses the PCR of the circuit. UBR circuits are assigned 100 cps
of bandwidth for load and reroute purposes, since it is a “best effort” service.

About ATM Logical Ports

About the Oversubscription Factor

Note – Appendix A describes how to tune the CAC to optimize your network. If you

tune the CAC properly, you can optimize network resources without adversely
affecting QoS.

PVC routing is determined by either an OSPF algorithm or the network administrator
(if you manually define the circuit path). Each time a PVC attempts to come up after
configuration, OSPF reserves the required bandwidth on the port. OSPF deducts the
amount of reserved bandwidth from the available virtual bandwidth pool for the
applicable CoS.

The available virtual bandwidth can become negative in extreme situations. For the
variable bit rate-non-real time (VBR-NRT) queue, if a number of trunks fail, PVC
rerouting may cause the available virtual bandwidth value to become negative.
Existing PVCs can be rerouted over a negative virtual bandwidth trunk. Ho we ver, new
PVCs cannot traverse trunks that have a negative virtual bandwidth. Any PVC that
fails during the time of the reroute is considered to be a new PVC when it attempts to
come up after the trunk is rerouted.

Since inter-LAN traffic is bursty in nature, not all network traffic uses the network
resources at precisely the same time. Basically, the higher you set the ov ersubscription
factor, the less guarantee there is that user data will get through on the port; the
trade-off is that you can provision more circuits on that port. If, however, all network
traffic attempts to use the network resources at precisely the same time (for example,
during multiple file transfer sessions over the same trunk), some traffic may be
delayed or even dropped.

About VP Shaping on the CBX 500 and CBX 3500

If you leave the oversubscription factor set for the minimum value of 100%, the port
delivers all user data for that class of service (CoS) without unanticipated delays or
excessive cell loss. A value of 200% effectively doubles the virtual bandwidth
available for that CoS.

Note – Lucent reserves a certain percentage of bandwidth for network management,
routing updates, and other management traffic.

About VP Shaping on the CBX 500 and CBX 3500

V irtual path (VP) shaping provides the ability to shape OPTimum trunk connections at
a specified PCR while preserving QoS integrity. This feature ensures that the
maximum rate of the OPTimum trunk traffic does not exceed the specified PCR. See
either the CBX 500, CBX 3500, or Navis EMS-CBGX SRN for appropriate revision
levels.

On a CBX 3500 or CBX 500 switch, you can enable VP shaping only if the host IOM
is equipped with certain revisions of the ATM Flow Control Processor (FCP) module.
The FCP supports flow control or VP shaping on a per-logical port basis. See the
CBX 500, CBX 3500, or Navis EMS-CBGX SRN for appropriate revision levels.

Shaping is performed by assigning each VP a single queue on the FCP. Shaping is
performed on all cells belonging to the OPTimum trunk VP at the specif ied OPT imum
trunk shaping rate. Each of the VPs (tunnel VPs) are shaped at a rate that is different
from the opt-trunk shaping rate (SR) and does not consume it. You can configure the
tunnel VP shaping rate on the Tunnel VP Shaping Rate tab in the Add Logical Port
dialog box in Navis EMS-CBGX. One PCR is provisioned for the f irst VP of the LPort
and the aggregate traffic is scheduled with this rate. As a result, the aggregate rate of
the traffic on the first VP never exceeds the provisioned PVC rate. Four queues are
maintained for each shaped VP. The CBR queue has the highest priority, followed by
VBR-RT, VBR-NRT, and ABR/UBR queues. VCCs within a shaped VP are mapped
to the four queues according to their QoS.

Only VPCs provisioned through circuit defined path (CDP) are allowed to route
through OPTimum trunks. Use Mixed VNN/PNNI on the Path tab in the circuit
provisioning dialog box to provision the VPCs.

For additional information and configuration instructions, see “ILMI/OAM

Attributes” on page 3-34.

About VP Shaping on the GX 550

When you configure OPTimum trunk, virtual UNI, or virtual NNI logical ports on phy
modules attached to GX 550 Multiservice WAN BIO2 or BIO-C modules, you can
enable VP shaping to provide egress traffic shaping. The VP shaping feature enables
multiple VPs that are destined to multiple endpoints to be shaped from a single
physical port at the egress. Traffic is shaped based on a user-defined shaping rate that
is defined on the Add Logical Port dialog box during logical port configuration.
