Cisco Catalyst 4500 Series Line Cards

Secure, Flexible, Nonstop Communications

Product Benefits

The Cisco

Catalyst

4500 Series Switches provide scalable nonblocking Layer 2–4 switching with

secure, flexible, nonstop communications, enabling business resilience for enterprises, small and

medium-sized businesses (SMBs), and Metro Ethernet customers deploying business-critical

applications. The Cisco Catalyst 4500 delivers predictable and scalable high performance, with

advanced dynamic quality-of-service (QoS) capabilities and configuration flexibility for enterprise

wiring closets and SMB access/core. Integrated resiliency features in both hardware and software

maximize network availability, helping to ensure workforce productivity, profitability, and customer

success. Its centralized, innovative, and flexible system design helps ensure smooth migration to

wire-speed IPv6 and 10 Gigabit Ethernet. The flexibility, scalability, and forward and backward

compatibility between generations of the Cisco Catalyst 4500 Series extend deployment life,

providing exceptional investment protection, reducing the total cost of ownership.

The Cisco Catalyst 4500 E-Series is a high-performance next-generation extension to the Cisco

Catalyst 4500 Series. The new "E-Series" is composed of the Cisco Catalyst 4500 Series

Supervisor Engine 6-E, E-Series line cards, and E-Series chassis that are designed for secure,

flexible, nonstop communications with superior backward and forward compatibility delivering

exceptional investment protection for organizations of all sizes.

Cisco Catalyst 4500 E-Series and Classic Line Cards

The Cisco Catalyst 4500 Series offers two classes of line cards: classic and E-Series. Classic line

cards provide 6 gigabits of switching capacity per slot. E-Series line cards increase the per slot

switching capacity to 24 gigabits. This increase in per slot switching capacity with the E-Series line

cards requires the Cisco Catalyst 4500 E-Series chassis and the Cisco Catalyst 4500 Series

Supervisor Engine 6-E. Classic line cards may be deployed in both classic and E-Series chassis

with either classic Cisco Catalyst 4500 Series supervisor engines or with the Supervisor Engine 6-

E. With the Supervisor Engine 6-E, the classic line cards per slot switching capacity remains at 6

gigabits per slot. However, because of the centralized switching architecture of the Cisco Catalyst

4500, the classic line cards will adopt all of the new Supervisor Engine 6-E features such as eight

queues per port, dynamic QoS, and hardware-based IPv6 routing. Please refer to the Supervisor

Engine 6-E data sheet for more feature details. Classic line cards and E-Series line cards may be

mixed and matched within a Cisco Catalyst 4500 E-Series chassis with no performance

degradation: classic line cards will operate at 6 gigabits per slot, and E-Series line cards will

operate at 24 gigabits per slot. Table 1 summarizes the chassis and supervisor support for both

classic and E-Series line cards.
