all Ethernet line cards on their Cisco Catalyst 4500 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 4500 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 4500 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 provide 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 4500 Series chassis and supervisor engines. For

example, line cards that shipped with the original Cisco Catalyst 4003 Switch in 1999 will work in

the Cisco Catalyst 4500 E-Series chassis. Because of the centralized architecture of the Cisco

Catalyst 4500, all line cards deployed in a chassis benefit from the enhanced features the

supervisor engine provides including Security, QoS, Layer 2/3/4 routing, and hardware-based

IPv6.

Following are descriptions of line cards that are available for Cisco Catalyst 4500 Series switches.
