Catalyst 5509 Switching System

The Cisco Catalyst^® 5509 is the company's modular switching platform for high-density, enterprise wiring closets. With a gigabit architecture that scales throughput to millions of packets per second (PPS), the Catalyst 5509 supports advanced multilayer features, such as end-to-end quality of service (QoS) or multicast enhancements, that provide the intelligence needed to support mission-critical applications.

Overview

The Catalyst 5509 is a nine-slot chassis that supports high-density, dedicated Token Ring or 10/100/1000 Ethernet switching. This chassis can support up to 384 user ports with only a 15A circuit requirement, allowing for easy installation in most wiring closet environments. The Catalyst 5509 also supports all of the advanced Cisco wiring closet features such as automatic protocol broadcast filtering to conserve valuable bandwidth, intelligent multicast forwarding to handle multimedia traffic, and load balancing over redundant links.

For Gigabit Ethernet applications, the Catalyst 5509 supports up to 38 ports of Gigabit Ethernet, the highest port density available today for the Catalyst 5500 Family. This capability can be combined with Cisco Gigabit EtherChannel^® technology. Gigabit EtherChannel technology enables multiple Gigabit Ethernet links to be treated as one logical link, for up to 8 Gbps (full duplex) of device-to-device throughput. Used in such a configuration, the Catalyst 5509 creates an industry-leading Gigabit Ethernet solution to meet the requirements of today's demanding and fast-growing enterprise intranets.

With its support for hot-swappable modules, power supplies, and fans, the Catalyst 5509 chassis delivers high availability for production networks. Dual redundant switching engines, power supplies, and a passive backplane design ensure full system redundancy for mission-critical environments. The Catalyst 5509 chassis fits into a standard 19-inch rack, and all system components are accessible from the same side of the chassis. Only one power supply is required to run a fully configured system.

Architecture

The Catalyst 5509 architecture delivers Catalyst 5500-class frame switching performance in a nine-slot chassis. The high-speed crossbar frame switching fabric uses an input/output (I/O) queuing model. This cost-effective architecture gives the most efficient switching fabric for unicast and multicast/multimedia applications. The Catalyst 5509 architecture delivers 3.6 Gbps of bandwidth to all slots. With switching modules that support local switching and deliver added forwarding capacity, the Catalyst 5509 architecture scales to more than 50 Gbps.

The Catalyst 5000 Family architecture maintains two additional buses, the management and index/control buses. The management bus is a serial bus that carries configuration information to each module and statistical information from each module to the Supervisor Engine. The index/control bus carries port-select information from the central encoded address recognition logic to the ports. This information determines which ports forward the packet and which flush it from the buffer. This architecture supports store-and-forward operation and uses fair arbitration and address recognition logic for all modules. Each frame that traverses the frame-switching bus may be destined to a single port or to multiple ports, allowing for high-speed multicast forwarding without the need for frame copies.

Summary

The Catalyst 5509 design is based upon proven Cisco switching technology that is being used in the largest campus networks in the world. For customers who need high-performance, high-density switching that is cost-effective and dependable, the Catalyst 5509 is an ideal platform. Table 1 gives the number of Ethernet ports that are deployable in a Catalyst 5500/5000 system.
