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.
