All about Cisco Catalyst 4500 Series

Today I am going to talk about the Cisco Catalyst 4500 Switch. The Cisco catalyst 4500 switch is widely used in the enterprise network as a Access switch. While in some of the small sites which can be branch or remote sites, it can be used as Core switch.


Cisco catalyst is an old catalyst with the best features while Cisco came up with the Cisco 9400 chassis based catalyst switch with the more features.


Let's not talk about Cisco 9400 catalyst switch right now, Let's talk about Cisco 4500 Catalyst switch as of now.


Cisco Catalyst 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.

  • Delivers up to 928 Gbps system bandwidth and nonblocking 48 Gbps per slot
  • Has eight nonblocking 10 Gigabit Ethernet uplinks with a field-programmable gate array to support next-generation protocols
  • Can scale up to 384 Gigabit copper ports, 200 Gigabit fiber ports, or 104 10-Gigabit ports in non-virtual switching system (VSS) mode
  • Offers 116 Universal Power of Ethernet (UPOE) (60 W), 240 PoE+ (30 W), and 384 PoE (15 W) with 9000 W power supply


Supervisor 8-E is compatible with all Cisco Catalyst 4500E chassis, line cards, and power supplies to help make full use of your investment. You also get:

  • Industry-leading investment protection with more than 10 years of backward compatibility for line cards
  • A software lifecycle of greater than three years with extended maintenance releases
  • Forward compatibility for new supervisors to easily deploy future innovations

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 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.


Power over Ethernet on Cisco Catalyst 4500E 

The Cisco Catalyst 4500E Series offers line cards, power supplies, and accessories required to deploy and operate standards-based Power over Ethernet/Power over Ethernet Plus (PoE/PoEP) and Universal POEP (UPOE). PoE provides power over 100 m of standard unshielded twisted-pair (UTP) cables when an IEEE 802.3af/at-compliant or Cisco pre-standard powered device is attached to the PoE/PoEP and UPOE line-card port. 

Instead of requiring wall power, attached devices such as IP phones, wireless base stations, video cameras, and other IEEE-compliant appliances can use power provided from the Cisco Catalyst 4500 Series PoE/PoEP and UPOE line cards. 


For the regular DC (Direct Current) device that doesn't support PoE/PoEP natively, Cisco Catalyst 4500 Series provides the UPOE Power Splitter that enables an UPOE port to power a 12V DC power device and another PoE/PoEP appliance. This capability gives network administrators centralized control over power and eliminates the need to install outlets in ceilings and other out-of-the-way places where a powered device can be installed. Table 2 shows the PoE options for Cisco Catalyst 4500 Series line cards. 


Although all references to “PoE/PoEP/UPOE,” “inline power,” and “voice” power supplies and line cards are synonymous, there are currently four versions: Cisco prestandard, IEEE 802.3af compliant, IEEE 802.3at compliant, and UPOE. Every Cisco Catalyst 4500 Series chassis and PoE power supply supports the IEEE 802.3af/at standard and the Cisco prestandard power implementation, helping ensure backward compatibility with existing devices powered by Cisco. UPOE line cards require E series chassis. 


All IEEE 802.3af/at-compliant and UPOE line cards can distinguish an IEEE or Cisco prestandard powered device from an unpowered network interface card (NIC), helping ensure power is applied only when an appropriate device is connected.

Cisco Catalyst 4500E Series and Classic Gigabit Ethernet Copper Line Cards

The Cisco Catalyst 4500E Series 48-port Gigabit Ethernet line cards provide high-performance 10/100/1000 switching. Two types of E-Series line cards are available, based on the per-slot bandwidth: 47xx line cards that drive 48 Gbps per slot, and 46xx line cards that drive 24 Gbps per slot. 

The Cisco Catalyst 4500 48-port 10/100/1000 PoEP E-Series 47xx line card provides standard IEEE 802.3at PoEP support on all 48 ports simultaneously. All series 47xx line cards support standard IEEE 802.1AE encryption and Cisco TrustSec™ in hardware. The Cisco Catalyst 4500 48-port 10/100/1000/multi-gigabit line cards are available in five versions: Data Only, PoE, PoEP, UPOE, and UPOE with multi-gigabit support for 802.11ac Wave2.
