For information about the ATM Interface Module, see the

Module User Guide Guide

The ATM Switch Fabric Module has a switching capacity of 15 Gbps. The high-performance, line-rate, non-blocking ATM Switch Fabric Module features highly integrated ASICs that account for its scalable, leading-edge performance and functionality. The module incorporates on-board A TM control hardware for scaling the performance of Switched Virtual Channel Connec ti on s (SVCs) and Swit che d V irtu al Path s (SV Ps).

The CoreBuilder 9000 ATM Enterprise Switch provides wire-speed interfaces for ATM OC-3c/STM-1, ATM OC-12c/STM-4, and ATM 155 Mbps-over-UTP5 daughter cards, which are listed in Table 4.

These cell-based daughter cards are designed to be installed into ATM Interface Modules that are inserted into CoreBuilder 9000 chassis slots. Each ATM Interface Module can accommodate two of the following daughter cards in any combination: OC-3c/STM-1, OC-12c/STM-4, and 155 Mbps-over-UTP5.

CoreBuilder 9000 ATM Enterprise Switch Characteristics

The OC-3c/STM-1 and OC-12c/STM-4 daughter cards are available in single-mode or mu lti-mode. An OC-3c/STM-1 card is available with three single-mode ports and one multi-mode port.

You can install up to 11 ATM Interface Modules in the 16-slo t chassi s and up to 5 ATM Interface Modules in the 7-slot chassis and the 8-slot chassis. You can order the ATM Interface Modules as a kit with daughter cards included or, you can order individual daughter cards separately.

Device Management

Traffic Management

You can use the CoreBuilder 90 0 0 ATM Enterprise Switch Local Management Application (LMA) or Transcend

Enterprise Manager (or other SNMP-based net w ork management application) to manage your CoreBuilder 9000 AT M Enterpri se Switch .

The CoreBui lder 9000 ATM Enterprise Switch LMA is a character-oriented, menu-driven user interface for perform i ng system-level administration. You operate this console from a terminal (or terminal emulation software) or through a remote terminal protocol, such as Telnet or Remote Login.

For more complete network management, use an external SNMP-based application such as Transcend Enterprise Manager. Transcend provides logical views and control for your network. In addition, it extends the SNMP capabilities of the ATM Enterprise Switch with a common user interface and easy-to-use administrative features that optimize network configuration, oversight, and troubleshooting.

Traffic management in th e CoreBuilder 9000 ATM Enterprise Switch is done at two levels:



Preventing congestion

Handling congestion

Mechanisms for Preventing Congestion

The following flow control mechanisms for automatic management in the CoreBuilder 9000 ATM Enterprise Switch Fabric Module work to prevent cell and frame loss under intense loads:



Partial Packet Drop (PPD) (Hardware ready)



Early Packet Dr op (EPD) (Hardware ready)





CLP-based Cell Discard.

ATM Networks

The CoreBui lder 9000 ATM Enterprise Switch supports the following types of ATM network s:

Classical IP (CLIP) ATM

The CoreBui lder 9000 ATM Enterprise Switch is transparent to CLIP and allows you to use CLIP over the ATM network. For a view of th e CoreBuilder 9000 ATM Enterprise Switch when CLIP is used over ATM within a network, see Chapter 3, ATM Network Basics in the Operations Guide.

Virtual Networks

The CoreBui lder 9000 ATM Enterprise Switch handles virtual networks across the enterprise using ATM and LAN Emulation (LANE). Segments in a virtual network can incorporate legacy LANs and ATM devices using LANE, allowing you to organize network users into logical groups, regardless of their physical location. Using this feature, you can set up workgroups compr ised of members fr om various departments or bu siness units around the enterprise, and centralize servers into server

farms

for better administration. For more informati o n abo ut virtu a l netwo rks, see Chapter 3, ATM Network Basics in the Operations Guide.
