THE SPECIFICATIONS AND INFORMATION REGARDING THE PRODUCTS IN THIS MANUAL ARE SUBJECT TO CHANGE WITHOUT NOTICE. ALL STATEMENTS, INFORMATION, AND RECOMMENDATIONS IN THIS MANUAL ARE BELIEVED TO BE ACCURATE BUT ARE PRESENTED WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED. USERS MUST TAKE FULL RESPONSIBILITY FOR THEIR APPLICATION OF ANY PRODUCTS.

THE SOFTWARE LICENSE AND LIMITED WARRANTY FOR THE ACCOMPANYING PRODUCT ARE SET FORTH IN THE INFORMATION PACKET THAT SHIPPED WITH THE PRODUCT AND ARE INCORPORATED HEREIN BY THIS REFERENCE. IF YOU ARE UNABLE TO LOCATE THE SOFTWARE LICENSE OR LIMITED WARRANTY, CONTACT YOUR CISCO REPRESENTATIVE FOR A COPY.

The following information is for FCC compliance of Class A devices: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio-frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference, in which case users will be required to correct the interference at their own expense.

The following information is for FCC compliance of Class B devices: The equipment described in this manual generates and may radiate radio-frequency energy. If it is not installed in accordance with Cisco’s installation instructions, it may cause interference with radio and television reception. This equipment has been tested and found to comply with the limits for a Class B digital device in accordance with the specifications in part 15 of the FCC rules. These specifications are designed to provide reasonable protection against such interference in a residential installation. However, there is no guarantee that interference will not occur in a particular installation.

You can determine whether your equipment is causing interference by turning it off. If the interference stops, it was probably caused by the Cisco equipment or one of its peripheral devices. If the equipment causes interference to radio or television reception, try to correct t he interference by using one or more of the following measures:

• Turn the television or radio antenna until the interference stops.

• Move the equipment to one side or the other of the television or radio.

• Move the equipment farther away from the television or radio.

• Plug the equipment into an outlet that is on a different circuit from the television or radio. (That is, make certain the equipment and the television or radio are on circuits controlled by different circuit breakers or fuses.)

Modifications to this product not authorized by Cisco Systems, Inc. could void the FCC approval and negate your authority to operate the product.

Cisco WAN Switching Product Name Change

The Cisco WAN Switching products ha ve ne w names. A switch in the BPX fami ly is no w part of the Cisco BPX® 8600 Series wide area switch family. The AXIS shelf is now called the Cisco MGX™ 8220 edge concentrator . An y switch in the IGX swi tch family (IGX 8, IGX 16 and IGX 32 wide- area switches) is now called the Cisco IGX™ 8400 series-wide area switch. The IGX 8 switch is now called the Cisco IGX™ 8410 wide-area switch. The IGX 16 switch is now called the Cisco IGX™ 8420 wide-area switch, and the IGX 32 switch is now called the Cisco IGX™ 8430 wide-area switch.

About This Manual xxv

Organization

This publication is organized as follows:

Chapter 1 Introduction

Describes the overall operation of the BPX 8600 Series wide-area switches and associated peripherals.

Chapter 2 General Description

Provides an overall physical and functional description of the BPX switch. The physical description includes the BPX enclosure, power, and cooling subsystems. The functional des cri pti o n i ncludes an overvie w of BPX swi tc h operation.

Chapter 3 BPX Switch Common Core

Describes the common co re group, comprising th e Broadband Controller Cards (BCCs), the Alarm/Status Monitor (ASM) card, associated back cards, and the StrataBus backplane.

Chapter 4 Network Interface (Trunk) Cards

Describes the BPX switch network interface (trunk) cards, including the Broadband Network Interface (BNI) and associated backcards. The BXM card trunk operation is briefly described in this chapter with additional information provided in Chapter 6.

Chapter 5 Service Interface (Line) Cards

This chapter contains a description of the BPX s ervice in terf ace ( line) car ds , including the ATM Service Interface (ASI) and associated backcards. The BXM card service (port UNI) operation is briefly described in this chapter with additional information provided in Chapter 6.

Chapter 6 BXM T3/E3, 155, and 622

Describes the BXM card group which i nclu des the BX M-T3 / E3, B XM-15 5, and BXM-622 card sets. Describes the operation of these cards in either trunk or service (port UNI) mode.

Chapter 7 ATM Connections

Describes how ATM connection services are established by adding ATM connections between ATM service interface ports in the network using ATM standard UNI 3.1 and Traffic Management 4.0. It describes BXM and ASI card operation and summarizes ATM connection parameter configuration.

Chapter 8 ATM and Frame Relay SVCs, and SPVCs

xxvi Cisco BPX 8600 Series Reference

Provides a summary of switched virtual circuits and soft permanent virtual circuits with respect to the BPX switch and co-located Extended Services Processor. For additional information, refer to the Cisco WAN Service Node Extended Processor Installation and Operation Release 2.2 document.

Chapter 9 Tag Switching

Provides a summary of tag switching on the BPX 8650 where the BPX switch and associated series 7200 or 7500 router comprise a BPX 8650 Tag Switch. Also provides configuration examples.

Chapter 10 BME Multicasting

Provides a description of BME multicasting and configuration examples.

Chapter 11 Repair and Replacement

Describes periodic maintenance procedures, troubleshooting procedures, and the replacement of major BPX switch components.

Chapter 12 Frame Relay to ATM Network and Service Interworking

Describes frame relay to AT M interworking which allows users to retain their existing Frame Relay services, and as their needs e xpand, migrate to the higher bandwidth capabilities provided by BPX ATM networks. Frame Relay to ATM Interworking enables frame relay traffic to be connected across high -speed ATM trunks using ATM standard Network and Service Interworking.

Organization

Chapter 13 Tiered Networks

Describes the tiered network configuration that provides the capability of adding interface shelves/feeders (non-routing nodes) to an IPX/IGX/BPX routing network.

Chapter 14 BPX SNMP Agent

Introduces the functions of the Simple Network Management Protocol (SNMP) agent and MIBs that are embedded in each BPX switch.

Appendix A BPX Node Specifications

Lists the BPX switch specifications.

Appendix B BPX Switch Cabling Summary

Provides details on the cabling required to install the BPX switch.

Appendix C BPX Switch Peripherals

Provide details on the specifications for peripherals used with the BPX switch.

Appendix D AT3-6ME Interface Adapter

Describes the AT3-6M Interface Adapter, sometimes referred to as the T3-T2 Interface Adapter, that may be used with the BPX switch to provide a 6 Mbps ATM network interface to T2 transmission facilities.
