Product Overview

The Cisco LightStream 2020 multiservice ATM switch is a high-performance multiservice ATM switch designed for campus and enterprise backbones, as well as public network deployment.

The core of the LightStream 2020 switch is a high-performance, cell-switching, crossbar fabric. The cell fabrics and network processors are supported by fully redundant, hot-swappable interfaces and power supplies, allowing for the extremely high availability that is key to enterprise-critical applications.

The LightStream 2020 switch midplane supports 12 strams, two of which are reserved for redundant switch modules. Either one or two other slots are used for Network Processor Modules (NPMs), depending upon whether redundancy is required. Up to nine slots are available for customer use. The LightStream 2020 switch supports a variety of fully hot-swappable interface modules to maximize deployment flexibility. See the section "Configuration Guidelines" for more information about module placement in the chassis. Figure 107 shows the front view of a fully loaded LightStream 2020 system. Figure 108 shows the rear view of the same system.

Interface modules consist of a variety of access cards, paired through the midplane with either a high-performance packet or cell line card. The access cards enable a variety of different physical interfaces, and the line cards provide packet or cell adaptation as appropriate.

The packet line card processes incoming non-ATM traffic and adapts it into ATM cells using either segmentation and reassembly into AAL5 packets for data traffic or packing into AAL1 cells for circuit emulation. The specialized, hardware-based packet header recognizer logic allows sophisticated packet filtering and processing options at full line speed.

The cell line cards perform ATM traffic and connection management functions including connection admission control, traffic shaping, and policing. The packet and cell line cards implement the LightStream 2020 switch's sophisticated congestion control mechanisms. All of these functions are implemented on high-performance application-specific integrated circuits (ASICs).

ATM interface modules can be configured either for end-system connectivity or as trunks to allow for high-performance ATM connectivity between multiple LightStream 2020 switches. A system of LightStream 2020 switches is interconnected using ATM trunk ports, while access to the system can be across a mixture of ATM, LAN switch ports, WAN ports, and circuit interfaces. Table 230 lists the interface modules and the ports supported for each module.


Standard Features

The LightStream 2020 switch includes the following standard features:


Interface Modules

The LightStream 2020 switch has several types of interface modules available:

Table 230 summarizes the LightStream 2020 interface modules.


STS3c/STM1 (OC-3c) Multimode and Single-mode Modules

The OC-3c multimode and single-mode modules consist of two major components: the cell line card (CLC) and the associated access card. Two module types are available: a module with a single port and a module with two independent ports. Use the single port version to support an internodal trunk line.


T3/E3 Modules

The T3 module consists of the CLC, the associated T3 access card, and the fantail/cable assembly. Fantail cables are available in several lengths (see Table 239). Two module types are available: a four-port module and an eight-port module. Use the four-port version of the T3 module to support internodal trunking.

The E3 module consists of the CLC, the associated E3 access card, and the fantail/cable assembly. Fantail cables are available in several lengths (see Table 239). Only the four-port version of the E3 module is available.


Circuit Emulation (T1/E1) Module

The circuit emulation module provides T1 and E1 circuit emulation. The T1 module consists of the packet line card (PLC) and the associated eight-port T1 circuit emulation access card (CEMAC). Three E1 module types are available:

The E1 fantail cable is available in several lengths (see Table 239).


Serial Interface Module (V.35, EIA/TIA-449, X.21)

The serial interface module consists of four major components: the packet line card (PLC), the serial access card, fantail cables, and the fantails. Each serial module supports up to two fantails and associated fantail cables. Fantail cables are available in several lengths (see Table 239). There are three versions of the fantail: one for V.35, one for X.21, and one for EIA/TIA-449. V.35 and EIA/TIA-449 fantail types have four ports each and can be configured on the same access card. A single X.21 fantail supports eight ports.


Dual-Attached Station Switched LAN FDDI Module

The FDDI module consists of two major components: the packet line card (PLC) and the associated FDDI access card. The FDDI access card has two DAS ports.


Ethernet Switched LAN Modules

The Ethernet module consists of two major components: the packet line card (PLC) and the associated Ethernet access card. Two module types are available: an eight-port 10BaseFL (fiber) version and an eight-port 10BaseT/AUI version.


Optional Modules

Optional modules for the LightStream 2020 switch include the following:


Low-speed Module

The low-speed module consists of four major components: the low-speed line card (LSC), the low-speed access card, fantail cables, and fantails. Each low-speed module supports up to two fantails and associated fantail cables. Fantail cables are available in several lengths (see Table 239). There are three versions of the fantail: one for V.35, one for X.21, and one for EIA/TIA-449. V.35 and EIA/TIA-449 fantail types have four ports each and can be configured on the same access card. A single X.21 fantail supports eight ports.


Cell Line Card

A cell line card (CLC) for the LightStream 2020 switch comes in two versions:

The singleport OC-3c modules and the four-port T3/E3 modules include a CLC with a single-to-switch unit (TSU) ASIC; the two-port OC-3c modules and the eight-port T3 modules include a double TSU ASIC CLC. The double TSU ASIC CLC operates with a one-port OC-3c or four-port T3/E3 access card. If a single TSU ASIC CLC is used with two-port OC-3c or eight-port T3/E3 access cards, only half the ports will be operational. Maintaining double TSU CLC cards is recommended.

Configuration Guidelines

This section provides helpful information for planning your LightStream 2020 switch chassis configuration. The LightStream 2020 switch supports 12 slots, two of which are reserved for redundant switch modules. Either one or two other slots are used for network processor modules (NPMs), depending upon whether redundancy is required. Up to nine slots are available for a variety of fully hot-swappable interface modules. Table 231 lists the slot numbers and the modules appropriate for use in those slots.

Table 231 : Slot Locations for LightStream 2020 Modules

Slot Number Module
Slot 1 Network processor
Slot 2 No restriction. Redundant network processor (if required)
Slots 3, 4, and 5 No restrictions on type of line card used
Slot A Switch card 1
Slot B Switch card 2
Slots 6, 7, 8, 9, and 10 No restrictions on type of line card


Configuring Ports

The HP OpenView-based management application, called StreamView, is used to configure ports for the LightStream 2020 multiservice ATM switch. The configurator management tool runs on an NMS and is used to create configuration database files for nodes in an ATM network.

The port type is determined by the configuration settings and the line card module (line card and access card combination). To configure a port you first select a card type from the Cards Configuration dialog box, giving you access to individual port attributes. The configurator card type names do not correspond directly to line module names.

The following tables provide information about configuring ports. Table 232 matches port types and interface modules with configurator edge card types. Table 233 matches port types and interface modules with configurator trunk card types. For more information about configuring and creating ports, see the LightStream 2020 Configuration Guide.

1 Up to four ports can be used when the module is configured as a trunk.
2 Although the card has two physical ports, only one port can be used when the module is configured as a trunk.


Software

The latest version of platform software is included with all packaged LightStream 2020 base systems and with all network processors modules and disk assemblies ordered from the spare parts list.

The following software products must be ordered separately:


StreamView Network Management Software

The StreamView software option includes three graphical network management tools:

The StreamView software requires a Sun SPARCstation running SunOS 4.1.4, HP-UX 9.0.5, and Solaris 2.4. The topology map must be used with the HP OpenView management software. At least one copy of the StreamView software should be purchased for each LightStream 2020 network.


Frame Relay DCE and NNI

The Frame Relay software works with the low-speed interface module to provide Frame Relay DCE and NNI service. Frame Relay software is available on a per-chassis basis.


ControlStream Traffic Management Software

ControlStream software, which is a mandatory component of the platform software, provides sophisticated traffic management capabilities. Primarily, this consists of a variety of mechanisms that operate to provide multiple classes of service and quality of service, and enforce these traffic contracts even during overload conditions. Additionally, ControlStream includes a congestion avoidance and control mechanism for monitoring trunk and egress port loading, feeding back this loading information to all sources and discarding excess traffic, fairly, at the edges of the network. Through ControlStream, traffic can be managed from the sources so that trunk congestion events can be avoided before they occur. ControlStream is available on a per-chassis basis.


VirtualStream Virtual LAN Software

The VirtualStream software option operates with the bridging service available for FDDI and Ethernet users and provides four value-added virtual LAN services:

A software license for VirtualStream is required for each Ethernet module or access card and for each FDDI module or access card.

Country Power Kits

A country power kit is required with each base system. Country power kits include power cord sets, labels, and instructions appropriate for the country of destination. All power cords are 8 feet 2 inches (2.5 meters) long. Country power kits are available as follows:

  • North America (125 VAC, 50--60 Hz; 125 VAC locking, 50--60 Hz; 250 VAC locking, 50--60 Hz)

  • Others: Argentina, Australia, Austria, Belgium, Denmark, Finland, France, Germany, Hong Kong, India, Ireland, Israel, Italy, Japan, Malaysia, the Netherlands, New Zealand, Norway, Papua New Guinea, Portugal, Singapore, South Africa, Spain, Sweden, Switzerland, and the United Kingdom


Note DC-powered systems do not use country power kits. Instead, order the DC power kit, L2020-PWR-DC.
