They enable security, mobility, application performance, video, and energy savings over an infrastructure that supports resiliency, virtualization, and automation. Cisco Catalyst Series Switches provide borderless performance, scalability, and services with reduced total cost of ownership TCO and superior investment protection. The Cisco Catalyst Figure 1 has a centralized forwarding architecture that enables collaboration, virtualization, and operational manageability through simplified operations. With forward and backward compatibility spanning multiple generations, the new Cisco Catalyst E Series provides exceptional investment protection and deployment flexibility to meet the evolving needs of organizations of all sizes. Integrated resiliency in both hardware and software minimizes network downtime, helping to ensure workforce productivity, profitability, and customer success. Figure 1.

The ports can be used interchangeably as Gigabit Ethernet and 10 Gigabit Ethernet to support phased migration from Gigabit Ethernet to 10 Gigabit Ethernet.
This capability further demonstrates the flexibility and the investment protection of the Cisco Catalyst Series architecture Figure 1. Figure 1.
The Cisco Catalyst Series 48 module Gigabit line card oversubscribed provides switching at 6Gbps per slot and can be used for higher density deployments. The Cisco Catalyst E Series 40 module Gigabit line card oversubscribed provides switching at 24Gbps per slot and can be used for enterprise deployments that require higher density and lower oversubscription. This line card also supports a specialized BX optics compact SFP that doubles the density to 80 ports per line card using 40 module, making it attractive for the FTTH deployment.
Figure 2. Compact SFP Cisco Catalyst Classic Fast Ethernet Fiber Line Cards The Cisco Catalyst Series offers a variety of classic Fast Ethernet line cards with fiber interfaces optimized for desktops, branch office backbones, and servers for enterprise and commercial switching solutions and service provider metropolitan Ethernet networks. Features and Benefits Functional Transparency Cisco Catalyst Series Switches offer an extensive line of modules that support numerous speeds and physical media combinations.
These line cards are functionally transparent; all the packet processing, queuing, buffering, and QoS occur in the supervisor engine. To that end, both classic and E-Series line cards acquire the features and capabilities of the installed supervisor engine. This architecture enables customers to easily upgrade all Ethernet line cards on their Cisco Catalyst Series systems to higher layer switching functions by adding a new supervisor engine.
The simple design of the line cards results in a very high mean time between failures MTBF , helping ensure high availability for a single connection to an end user. Modular Versatility The Cisco Catalyst Series is a centralized architecture that is designed to provide dedicated wire-speed bandwidth to each line-card slot within the chassis.
Each line card has a dedicated bandwidth to the supervisor engine for packet processing. All network data that flows into the Cisco Catalyst Series through the various line cards goes through the supervisor engine for processing, even in single-slot port-to-port communications.
All line cards have some per-slot bandwidth that allows network administrators to design a system that offers full dedicated bandwidth-to-server and switch-to-switch applications and still provides high performance over subscribed gigabit to the desktop. A modular centralized design allows customers to use their investment in high-performance line cards across the entire line of Cisco Catalyst Series chassis and supervisor engines.
For example, line cards that shipped with the original Cisco Catalyst Switch in will work in the Cisco Catalyst E Series chassis. Following are descriptions of line cards that are available for Cisco Catalyst Series Switches. Figure 3. Figure 4. Figure 5. Figure 6. Figure 7. Figure 8. Figure 9.
