TECHNOLOGY SPOTLIGHT
The architectural foundation of the Intelligent Information Network.
Cisco Systems offers the industry’s most complete range of switching solutions, supporting a wide variety of deployment requirements in networks of every size. Yet Cisco Catalyst switches are much more than a collection of point products to meet isolated IT needs; they are part of an integrated approach to the broader goals of protecting, optimizing, and growing networks for years to come.
Cisco Catalyst switches provide an architectural foundation for the intelligent services that enable new applications and uses for the network. Key elements include:
Hardware Integration
At the core of Cisco’s hardware integration is application-specific integrated circuit (ASIC) innovation. Cisco has developed more than one hundred ASICs for the Cisco Catalyst switching family since1995, with each generation including more capabilities. For example, Cisco was the first vendor to integrate Layer 3 switching into hardware, and has gone on to integrate security access control lists (ACLs), quality of service (QoS) classification, and queuing across the entire Cisco Catalyst line. Cisco is also the only switching vendor to offer hardware-based services modules, which integrate key functions such as firewalling, content networking, and network analysis directly into Catalyst 6500 switches.
Predictable Performance
Cisco offers among the highest performance modular and stackable switches in the industry, but throughput alone is not enough. Organizations need to be assured of predictable performance, regardless of variables like congestion, traffic type, or the use of softwareor hardware-enabled services. That’s why
all Cisco Catalyst switches are designed to maintain predictable performance through a unique combination of mechanisms, including Cisco Express Forwarding (CEF), Ternary Content Addressable Memory (TCAM), buffering, and congestion management. This ensures that network managers can enable complex features without fear of losing speed in their networks.

High-Density Gigabit and 10 Gigabit Ethernet
The Catalyst portfolio leads the industry in Gigabit and10 Gigabit Ethernet (10GbE) port density. Desktop Gigabit Ethernet, also called 10/100/1000, provides investment protection for future connectivity needs while also making use of the “free” LAN-on-motherboard solutions shipping on most new desktop and laptop computers. Additionally, the ability to process networked applications faster means that each PC’s performance improves, increasing productivity. Similarly,10GbE is being rapidly adopted in many enterprise networks, particularly in the network core, distribution, and in data center networks. Together, Gigabit Ethernet and10GbE help to ensure rapid access into the network and between network devices.
Power over Ethernet
Cisco pioneered the delivery of Power over Ethernet (PoE), simplifying the deployment of devices such as IP phones and wireless access points by eliminating the need for additional power cabling. Cisco drove the 802.3af power standard through IEEE and today offers extensions to the IEEE standard through the use of intelligent power management. In keeping with Cisco’s evolutionary approach, the Cisco Catalyst line includes switches that support both pre-standard inline power as well as IEEE 802.3af-compliant devices, enabling our customers to deploy new technology while continuing to make the most of past investments.

TECHNOLOGY SPOTLIGHT
End-to-end intelligent switching
for today’s converged network services.
The LAN switching infrastructure connects users, applications, and communications systems together. That basic task has become much more challenging as the variety and complexity of network uses have increased. Cisco Catalyst switches provide the intelligent services required to create secure, resilient networks that optimize the delivery of disparate services, yet remain easy to configure, manage, and troubleshoot.

Cisco Catalyst switches support today’s technology trends and business goals through a unique combination of intelligent capabilities. Major advantages include:
Integrated Security
Cisco Catalyst switches help make networks self-defending. Encrypted passwords, multilevel account privileges, and authentication protocols prevent unauthorized network access—a problem exacerbated by the rapid adoption of wireless networking. The switches can also prevent devices from connecting if they fail to meet certain criteria, such as having the latest antivirus software. Users can be separated into private subnets to permit varying levels of access. Other features enable the switches to protect themselves from worms and denial-of-service (DoS) attacks, prevent routing and spanning tree information from being spoofed, and ensure malicious users can’t steal confidential information, either from the company or from other employees.
Delivery Optimization
Today’s networks must be intelligent and adaptable enough to meet the varying requirements of converged data, voice, video, and storage traffic. Cisco Catalyst switches optimize the delivery of disparate traffic types using three key technologies: quality of service (QoS), multicast, and content switching.
QoS allows network managers to prioritize traffic and ensure low-latency traffic, such as voice, gets handled accordingly. Multicast makes it much more efficient to deliver video or music on-hold to multiple points on the network, reducing the burden on servers. The Cisco Catalyst 6500 Series Content Switching Module adds advanced Layer 4–7 load balancing to the Catalyst line’s existing Layer 2 and 3 features, further optimizing service delivery.
Availability and Resiliency
Cisco Catalyst switches help maintain the highest levels of network availability and resiliency. Each switch is designed to protect itself from hardware, software, power, or connection failures—or at the very least, minimize recovery times by enabling redundant backup systems and protocols to take over in as little as a millisecond. The switches are also designed to increase resiliency on a network-wide level, utilizing an array of Cisco innovations to recover from device, link, or protocol failures and maintain uninterrupted access. Integrated security features also play a role in preserving availability in the event of incidents like DoS attacks. Conversely, resilient designs help networks recover faster from security breaches, or even nullify their impact.
Enhanced Manageability
All Cisco Catalyst switches offer enhanced capabilities that make them much easier to configure, manage, and troubleshoot. These include wizards that automatically configure switches, integrated Web-based management tools, device discovery and intelligent power management features for PoE equipment such as IP phones and wireless access points, and an array of data collection and analysis tools. The benefits are real-time visibility, faster response and repair times, more adaptive policy management, and reduced cost and complexity. In the case of the Cisco Catalyst 6500 Series, optional Network Analysis Modules embed a rich set of management features on a single blade, providing volumes of performance information without burdening the switch itself.

Modular Switches
The Cisco Catalyst 6500 and 4500 Series modular switches provide customers with an intelligent high performance platform for deploying numerous concurrent intelligent services without degrading the overall performance of the switch. With a broad selection of line cards, power supplies, and their highly versatile architecture, modular switches deliver the highest levels of port density and flexibility, including PoE scalability to deploy new converged applications and extending investment protection well into the future. The modular architecture also provides scalable performance via a selection of supervisors which can be upgraded to enhance the performance and service features of the entire switch as needed.
To minimize costly user downtime, modular switches are optimized for high availability. Critical redundant hardware and software features deliver the highest resiliency for all places in the network. Another key advantage is the ease of use of modular switches. Modular switches have a single IOS image to manage no matter how many line cards are inserted. This allows for simpler IOS configurations, updating,
and management leading to a reduction in overall cost of ongoing operations.

Series Spotlight
Cisco IOS Software Modularity
Catalyst 6500 Series with Cisco IOS Software Modularity boosts operational efficiency and minimizes downtime through evolutionary software infrastructure advancements. By enabling modular Cisco IOS subsystems to run as independent, self-healing processes, this innovation minimizes unplanned downtime through fault containment and stateful process restarts, simplifies software changes through subsystem In-Service Software Upgrades (ISSU), and enables process-level, automated policy control by integrating
the Embedded Event Manager (EEM).
Maximum PoE Scalability
Cisco Catalyst 6500 Series provides the industry leading levels of power scalability needed to support high-density PoE deployments. The enhanced 6- and 9-slot chassis (C6506-E and C6509-E models) are designed to scale beyond the current 6000W power supplies. Continuing this product line’s tradition of unmatched investment protection, all existing supervisors, line cards, switch fabrics, and software releases are supported in the E-series chassis.
