The Cisco Catalyst 4500 Series provides the network infrastructure for all applications that will be integrated to solve business problems. Extending
intelligent network services with integrated resiliency leads to control of all traffic types with minimal downtime. The Cisco Catalyst 4500 Series
delivers this control with the following:
• Integrated resiliency—Network downtime is minimized with redundant supervisor engine (subsecond failover) capability (Cisco Catalyst 4507R
and Catalyst 4510R switches), software-based fault tolerance, redundant fans, and 1+1 power-supply redundancy across the Cisco Catalyst 4500
Series. Integrated Power over Ethernet (PoE) in all Cisco Catalyst 4500 Series chassis simplifies network design and limits the number of points
of failure in an IP telephony implementation.
• Sophisticated QoS—Integrated QoS and traffic-management capabilities based on Layer 2–4 classify and prioritize mission-critical and timesensitive traffic based on 32,000 QoS policy entries. The Cisco Catalyst 4500 Series can shape and rate-limit bandwidth-intensive traffic with
mechanisms such as input and output policers based on host, network, and application information.
• Predictable performance—The Cisco Catalyst 4500 Series offers up to a 102-million packets per second (mpps) wire-speed forwarding rate in
hardware for Layer 2–4 traffic. Switching performance is independent of the number of route entries or advanced Layer 3 services enabled.
• Advanced security—Support for Cisco patented Layer 2 security features prevents security breaches from rogue servers as well as “man in the
middle” attacks where passwords and data may be intercepted. Layer 2–4 filtering and policing are also supported to mitigate the traffic initiated
from malicious network attackers.
• Comprehensive management—The Cisco Catalyst 4500 Series offers Web-based management for the configuration and control of all ports,
allowing central management of critical network characteristics such as availability and responsiveness.
Convergence lowers the overall cost of network ownership and simplifies administration and maintenance through the elimination of separate voice,
video, and data infrastructures. The modular architecture of the Cisco Catalyst 4500 Series provides the scalability and flexibility to eliminate the
need for multiplatform deployments, minimizing maintenance expenses. To further extend customers’ network-equipment deployment cycles, the
Cisco Catalyst 4500 Series offers the following features:
• Backward compatibility of line cards—Customers are given the flexibility to upgrade line cards with the existing deployed chassis to higherspeed interfaces without changing the complete chassis, postponing the need for additional capital expenditures.
• Extra room for future features—The Cisco Catalyst 4500 Series architecture was designed with generous amounts of hardware resources
to support future features applicable to your network needs. With a simple Cisco IOS Software upgrade, you can receive the benefits of many
hardware-enabled features without the need for a complete chassis upgrade.
The Cisco Catalyst 4500 Series includes four chassis options: Cisco Catalyst 4510R (10 slots), Catalyst 4507R (7slots), Catalyst 4506 (6 slots), and
Catalyst 4503 (3 slots). The Cisco Catalyst 4500 Series provides a common architecture, taking advantage of existing Cisco Catalyst 4000 Series line
cards scaling up to 388 Ethernet ports. Offering compatibility with existing Cisco Catalyst 4000 Series line cards and supervisor engines, the Cisco
Catalyst 4500 Series extends its window of deployment in converged networks.
The Cisco Catalyst 4500 Series provides advanced, high-performance solutions for enterprise LAN access, small backbone networks, Layer 3
distribution points, and integrated SMB and branch-office solutions. Benefits include the following:
• Performance—Delivering advanced switching solutions that scale bandwidth as ports are added, the Cisco Catalyst 4500 Series is powered by
leading-edge, application-specific integrated circuit (ASIC) technology that offers wire-speed Layer 2–3 10/100 or gigabit switching. Providing
modular supervisor flexibility with complete line-card compatibility, Layer 2 switching can scale up to 136 Gbps, 102 mpps. Based on Cisco
Express Forwarding, Layer 3–4 switching can also scale up to 136 Gbps, 102 mpps.

• Port density—The Cisco Catalyst 4500 Series meets network-element connectivity requirements of up to 388 Ethernet ports in a chassis. The
Catalyst 4500 Series supports the industry’s highest-density 10/100/1000 autosensing, autonegotiating Gigabit Ethernet from the network edge
directly to desktop computers. Optional 10 Gigabit Ethernet uplink ports help enable high-density Gigabit Ethernet-to-the-desk deployments and
switch-to-switch applications. The hot-swappable, modular, easy-to-use switching solution of the Catalyst 4500 Series reduces complexity and
easily supports the changing desktop environments of today’s networks.
• Supervisor-engine redundancy—The Cisco Catalyst 4507R and Catalyst 4510R switches support 1+1 supervisor-engine redundancy for
integrated resiliency. Redundant supervisor engines help minimize network downtime, facilitating business continuance and increasing employee
productivity. With the support of stateful switchover (SSO), the secondary supervisor engine serves as a backup to immediately take over in
subsecond time upon a primary supervisor failure. During the switchover, Layer 2 links are maintained transparently without the need to
renegotiate sessions. As a result, business-critical applications such as voice over IP (VoIP) calls are not dropped. The Nonstop Forwarding (NSF)
Aware feature in Cisco IOS Software is also supported, providing the ability to interface with NSF-capable devices and to continue forwarding
packets as routing information is updated upon a supervisor-engine switchover.
• Power over Ethernet (PoE)—The Cisco Catalyst 4500 Series supports the 802.3af standard for PoE on 10/100 or 10/100/1000 ports, allowing
customers to support telephones, wireless base stations, video cameras, and other appliances. PoE makes it possible to place devices in unique
locations without having to provide new outlets and costly electrical circuits. Moreover, PoE allows businesses to isolate critical devices on a
single power system—so the entire system can be supported by uninterruptible power supply (UPS) backup.
All new Cisco Catalyst PoE line cards can support 15.4 watts (W) of power per port simultaneously. Not only do the cards support the IEEE
standard, including the optional power classifications, but the Cisco prestandard power implementation is also supported to help ensure backward
compatibility with existing Cisco powered devices. The cards are compatible with any Cisco Catalyst 4500 Series chassis and supervisor engine.
Most importantly, the Catalyst 4500 Series has the power supplies and accessories to support 15.4W per port on every port simultaneously in any
fully loaded chassis.
• Advanced security—Enabling security features such as 802.1x, access control lists (ACLs), Secure Shell (SSH) Protocol, port security, Dynamic
ARP Inspection (DAI), IP Source Guard, and private virtual LANs (PVLANs) on the Cisco Catalyst 4500 Series enhances control and flexibility
in the network. By enabling these features selectively or collectively, a network administrator can prevent unauthorized access to servers or
applications, allow different people to use the same PC with different permissions, prevent network intruders from stealing usernames and
passwords to access switches, or prevent a deliberate or accidental broadcast storm.
• Cisco IOS Software network services—Cisco Catalyst 4500 Series switches provide mature enterprise Layer 2–3 features capable of enhancing
corporate networks. These features meet the advanced networking demands of medium-sized and large enterprise businesses because they have
been improved based on years of customer feedback.
• Consistent software architecture—Because of the consistent Cisco Catalyst software and user interfaces, you can take advantage of your
knowledge base and continue to grow your infrastructure using a combination of Cisco Catalyst 2950, Catalyst 3550, Catalyst 3560, Catalyst
3750, Catalyst 4500, and Catalyst 6500 series switches.
• Investment protection—The flexible modular architecture of the Cisco Catalyst 4500 Series provides cost-effective interface upgrades for LAN
access or the branch-office network. Customers deploying the Cisco Catalyst 4503 and Catalyst 4506 switches with older supervisor engines who
want higher performance and enhanced features can easily upgrade to the Cisco Catalyst 4500 Series Supervisor Engine II-Plus, II-Plus-TS, IIPlus-10GE, IV, V or V-10GE. Compatible sparing between the Catalyst 4500 Series, Catalyst 4003, and Catalyst 4006 chassis provides
commonality of power supplies and switching line cards, lowering the overall deployment, migration, and support costs.
• Functionally transparent line cards—Cisco Catalyst 4500 Series systems can easily upgrade all system ports to higher-layer switching functions
by simply adding a new supervisor engine. Higher-layer functional enhancements are possible on all system ports without replacing existing line
cards and wiring, unlike conventional switching products where complete equipment upgrades are typical during migration. This architectural
advantage extends the useful deployment life of Cisco Catalyst 4500 Series line cards.
• Gigabit to the desktop—The Cisco Catalyst 4500 Series already provides numerous 1000-Mbps desktop and server switching solutions.
The scope of its gigabit solutions is easily extended to the desktop, with 48- and 24-port triple-speed autosensing and autonegotiating
10/100/1000BASE-T line cards for the Catalyst 4500 Series. The triple-speed 48- and 24-port modules, with autosensing technology, provide
LAN investment protection by allowing Fast Ethernet desktops to migrate to Gigabit Ethernet in the future without replacing the line cards.

The Catalyst 4500 Series Supervisor Engine V-10GE provides two wire-speed 10 Gigabit Ethernet uplinks that are optimized for
10/100/1000BASE-T-to-the-desktop aggregation.
• Hardware-based multicast—Protocol Independent Multicast (PIM), dense and sparse mode, Internet Group Management Protocol (IGMP),
and Cisco Group Management Protocol support standards-based and Cisco technology-enhanced efficient multimedia networking without
compromising performance.
• Manageability—The Cisco Catalyst 4500 Series is supported by the CiscoWorks product line, which provides innovative tools to centrally
manage critical network characteristics such as availability, responsiveness, resilience, and security for the intelligent-switching infrastructure. A
common modular QoS command-line interface (CLI) simplifies the creation of policy traffic maps and delivers a consistent interface across large
and small Cisco Catalyst switches. Network operations are enhanced with flexible Web-, GUI-, and CLI-based management alternatives. Best of
all, behind every Cisco Catalyst 4500 Series Switch are Cisco service and support solutions.
• Cisco NetFlow Services—The Cisco NetFlow Services Card for the Supervisor Engine IV and V support statistics capture in hardware for flowbased and VLAN-based statistics monitoring. This data can be exported, collected, and analyzed for virus detection and mitigation, network-traffic
accounting, usage-based network billing, network planning, network monitoring, and data-mining capabilities for both service provider and
enterprise customers. Note: NetFlow support on the Supervisor Engine V-10GE is built into the hardware and does not require the NetFlow
Services Card.
• Bandwidth protection for mission-critical applications—When deploying the Cisco Catalyst 4500 Series Supervisor Engine, there is no
degradation of forwarding performance with QoS or security features enabled; the Catalyst 4500 Series platform continues to forward at full line
• Fiber to the desktop—The Cisco Catalyst 4500 Series 100BASE-X line cards offer the security and resiliency features of fiber-optic cable plants,
making them ideal for networks with distance limitations, intrusion vulnerabilities, or RF interference. Enterprise customers or government
agencies that process confidential information or offer e-commerce will appreciate the security benefits of these line cards.
Multilayer Switched Enterprise Network with Ethernet Backbone
Today’s leading-edge network designs use a combination of Layer 2 and 3 services in the LAN (Cisco Catalyst 4500 Series) and Layer 3 routing
in the distribution and core-network layers (Catalyst 4500 or Catalyst 6500 series). The Catalyst 4500 Series supports IP-only routing in hardware
(Internetwork Packet Exchange [IPX] protocol and AppleTalk in software) with the Catalyst 4500 Series Supervisor Engines, and can be deployed
in low-density distribution points in the enterprise network (Figure 2).
The distribution-layer Cisco Catalyst 4500 Series switches use the Cisco Express Forwarding routing engine, capable of scaling up to 136 Gbps
at 102 mpps (on the Catalyst 4500 Series Supervisor Engine V-10GE). This helps enable millions of packets-per-second throughput of Layer 3
switching performed in hardware, with no penalty for header-prefix lengths.
