FEATURES AND BENEFITS
Functionally Transparent
The Catalyst 4500 Series Switch offers 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, the 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 4500 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 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 customer to use their investment in high-performance line cards across the entire line of Catalyst 4500 chassis
and supervisor engines. For example, line cards shipping with the original Catalyst 4003 Switch will work in the new Catalyst 4500 Series running
the Cisco Catalyst 4500 Supervisor Engine V.
Following is a list of line cards that are available for the Catalyst 4500 Series Switch:
