ATM Solutions

The central slot in the LightStream 1010 is dedicated to a single, field-replaceable ATM switch processor module (ASP) that supports both the 5-Gbps shared memory, fully nonblocking switch fabric, together with its feature card, and the high-performance RISC processor that provides the central intelligence for the device. Uniquely, the ASP module feature card can also be upgraded in the field, allowing the switch to track changing ATM specifications. The remaining slots support up to four hot-swappable carrier modules (CAMs), each of which, in turn, can support up to two hot-swappable port adapter modules (PAMs), for a maximum of eight PAMs per switch, supporting a wide variety of desktop, backbone, and wide-area ATM interfaces.

The LightStream 1010 offers the sophistication and depth of functionality required for true ATM production deployment. Advanced traffic management mechanisms allow for the support of current, bursty, best-effort traffic, while also delivering the quality of service (QOS) guarantees required for the applications of the future. Available bit rate (ABR) congestion control support allows the LightStream 1010 to slow traffic sources before congestion becomes excessive, while support for the ATM Forum PNNI protocols allows networks of LightStream 1010s to scale to hundreds of nodes while still delivering interoperable, QOS-based routing. Value-added capabilities allow for ATM access lists and load sharing across redundant links. All of this sophistication is hidden, however, by the true standards-based, plug-and-play capabilities of the LightStream 1010, and advanced management functions allow for unprecedented levels of network visibility and control.

• Five-slot chassis (same as that of the Catalyst 5000) with ATM backplane and fan tray

• Optionally redundant, auto-sensing, load-sharing AC-input or DC-input power supplies

The LightStream 1010 uses two management tools: AtmDirector and CiscoView.

AtmDirector is a graphical, system-level ATM management application for configuring, monitoring, and troubleshooting a network of Cisco LightStream ATM switches and ATM-attached Cisco routers and Catalyst LAN switches. The AtmDirector application automatically discovers and illustrates the topology of the ATM network, displays real-time link information, facilitates ATM network interrogation and troubleshooting by allowing selection of any virtual connection on an ATM link and tracing its entire path, and provides an intuitive interface for creating PVCs across the ATM network. AtmDirector can be integrated with popular SNMP management platforms or used as a fully functional, independent ATM network management application.

These advanced ATM management functions provide real-time status, statistics, and configuration information, allowing the administrator to more easily understand and use the complex management data available for ATM networks.

The CiscoView application is also included within CiscoWorks, Cisco's enterprise network management application suite. The application displays a physical view of any Cisco device and shows real-time LED and interface status. The CiscoView application provides comprehensive monitoring functions and simplifies basic troubleshooting tasks.

Using the CiscoView application for the LightStream 1010, users can more easily understand the complex management data and configuration parameters available for ATM switches. It organizes this information into graphical representations presented in a clear, consistent format.

The CiscoView application for the LightStream 1010 can be integrated with several of the leading network management platforms, providing management application integration. It can also be run on UNIX workstations as a fully functional, independent LightStream 1010 management application. In addition, it can be launched from the AtmDirector topology map by simply double-clicking on a LightStream 1010 icon.

• The default IISP image, which supports only the IISP protocol for ATM routing

• The PNNI image, which supports both the IISP and PNNI Phase 1 protocols

• The Cisco IOS for ATM image, which is a superset of the PNNI/IISP image

The LightStream 1010 uses the same power cords as the Cisco 7000 router and the Catalyst 5000.

When ordering a LightStream 1010 system that has been configured by the factory, the following items must be included on the purchase order:

• Base switch chassis (L1010-BASE5 or L1010-BASE5-DC)--includes one power supply

• Country-specific power cord

• Base ASP module (WATM-ASP1)

• Required memory configuration; one of the following:

  • 16-MB DRAM (MEM-ASP-16M)--default, included in base chassis price

  • 32-MB DRAM (MEM-ASP-32M)--additional cost

  • 64-MB DRAM (MEM-ASP-64M)--additional cost

• Required software subset image; one of the following:

  • IISP feature set (SF-WAS1-11.1.x)--default, included in base chassis price

  • PNNI/IISP feature set (SF-WAS2-11.1.x)--additional cost

  • Cisco IOS software for ATM feature set (SF-WAS3-11.2.x)--additional cost

All other components--redundant power supply, carrier modules, port adapter modules, and Flash memory cards--are options; these can be ordered at the same time as the base chassis if you want to have them installed in the factory. They can also be ordered as spares, as can the chassis, ASP, ASP DRAM SIMMs, and ASP Flash memory cards. Configuration rules should also be followed when ordering a spare ASP module; the cost of the default software image is included in the spare ASP price.
