 4500 Series Switches enable borderless unified wired and wireless networks, providing high-

performance, mobile, and secure user experiences through Layer 2-4 switching. Enabling security, mobility, 

application performance, video, and energy savings over your network infrastructure, the Cisco Catalyst 4500 

Switch supports resiliency, virtualization, and automation, further improving the ease of network use. Cisco 

Catalyst 4500 Series Switches provide borderless performance, scalability, and services with reduced total cost of 

ownership (TCO) and superior investment protection. 

The Cisco Catalyst 4500 Switch delivers predictable and scalable high performance, with advanced dynamic 

quality of service (QoS) capabilities and configuration flexibility for deploying borderless networks. 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 (GE). The forward and backward 

compatibility between generations of the Cisco Catalyst 4500 Series extends deployment life, providing exceptional 

investment protection, while reducing the (TCO). 

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

Series. The new E-Series is composed of the Cisco Catalyst 4500E Series supervisor engines, E-Series line cards, 

and E-Series chassis, which are designed for a high-performance, mobile, and secure user experience with 

superior backward and forward compatibility, delivering exceptional investment protection for organizations of all 

sizes. 

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 provide increased switching capacity per slot. This 

increase in per-slot switching capacity with the E-Series line cards requires the Cisco Catalyst 4500E Series 

chassis and the Cisco Catalyst 4500E Series Supervisor. Two types of E-Series line cards are available based on 

the per-slot switching capacity. E-Series line cards numbered 47xx operate at 48 gigabits per slot, while E-Series 

line cards numbered 46xx operate at 24 gigabits per slot. 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 Cisco Catalyst 

4500E Series Supervisor Engine. With the E-Series supervisor engine, the per-slot switching capacity for classic 

line cards 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 E-Series supervisor engine features such as eight 

queues per port, dynamic QoS, and hardware-based IPv6 routing. For more feature details, refer to the E-Series 

supervisor engine data sheet. Classic line cards and E-Series line cards may be mixed and matched within a Cisco 

Catalyst 4500E Series chassis with no performance degradation: classic line cards will operate at 6 gigabits per 

slot, and E-Series line cards operate at either 48 gigabits per slot or 24 gigabits per slot based on whether they 

belong to the 47xx or 46xx family of line cards. Table 1 summarizes the chassis and supervisor support for both 

classic and E-Series line cards.
