Optimal Control for Voice, Video, and Data Services
PRODUCT OVERVIEW
The Cisco Catalyst 4500 Series switches with integrated resiliency are designed for business services aggregation and subscriber access in metropolitan-area networks (MANs) that use the simplicity and flexibility of optical Ethernet in the first mile. These switches offer high-density Fast and Gigabit Ethernet for both fiber and copper combined with mechanisms for per-subscriber traffic management, security, performance, and quality of service (QoS). The Cisco Catalyst 4500 Series also offers nonblocking switching in Layers 2 through 4 with integrated resiliency, further enhancing control of "triple-play" voice, video, and data metro services.
The Cisco Catalyst 4500 Series includes four Cisco Catalyst chassis: the Cisco Catalyst 4510R Switch (10 slots), the Cisco Catalyst 4507R Switch (7 slots), Cisco Catalyst 4506 Switch (6 slots), and Cisco Catalyst 4503 Switch (3 slots). Integrated resiliency enhancements offered in the Cisco Catalyst 4500 Series include 1+1 supervisor-engine redundancy (Cisco Catalyst 4507R and Cisco Catalyst 4510R), software-based fault tolerance, and 1+1 power-supply redundancy. Integrated resiliency in both hardware and software minimizes network downtime, helping to ensure profitable services.
Compatible with all Cisco Catalyst 4500 Series line cards and supervisor engines, the Cisco Catalyst 4500 Series reduces the cost of ownership by minimizing recurring operational expenses, improving return on investment (ROI).
With the Cisco Catalyst 4500 Series, a primary member of the comprehensive Cisco Metro Ethernet portfolio, network operators can extend control and intelligence to large and small sites at the MAN edge. The Cisco Metro Ethernet portfolio encompasses a variety of routing, switching, and optical products and a range of technologies, including IP/Multiprotocol Label Switching (MPLS), Ethernet, SONET/SDH, and dense wavelength-division multiplexing/coarse wavelength-division multiplexing (DWDM/CWDM). Cisco Systems offers network operators a flexible, service-oriented approach for delivering profitable and differentiated metropolitan and broadband services.
THE ETHERNET ADVANTAGE IN MANS
Because of the cost, speed, and flexibility advantages of Ethernet, service providers are looking to offer Metro Ethernet as a connectivity option to their business and residential customers. Enterprise customers are asking providers to standardize on Ethernet as the User-Network Interface (UNI) everywhere on their networks to reduce expenses. Ethernet is familiar to enterprise customers and their IT staffs. It can scale to deliver bandwidth up to 10 Gbps to support demanding applications, and its bandwidth can be tailored to deliver performance that meets the needs of specific business applications. Providers of residential Internet, voice over IP (VoIP), and video services can also take advantage of this flexibility using advanced security and rich quality of service (QoS) capabilities delivered on the Cisco Catalyst 4500 Series via sophisticated control features of Cisco IOS Software and specialized hardware. Whether in MAN access or aggregation, Ethernet technology offers the most effective transport for service requirements today and in the future. By offering Ethernet-based services that can support more advanced applications, service providers can differentiate their offerings from competitors, improve their profit margins, and improve their revenue potential over the long term.
OPTIMAL CONTROL
The Cisco Catalyst 4500 Series provides Metro Ethernet edge networks optimal control, from managing network and subscriber security to service differentiation. The Cisco Catalyst 4500 Series delivers this control with the following:
• Integrated resiliency-Network downtime is minimized with redundant supervisor-engine capability (on the Cisco Catalyst 4507R and 4510R), software-based fault tolerance, and 1+1 power-supply redundancy across the Cisco Catalyst 4500 Series. Nonstop Forwarding (NSF) with Stateful Switchover (SSO) offers continuous data packet forwarding during switchover. With time-sensitive traffic, including voice and video, running over the Metro Ethernet edge network, integrated resiliency is essential for maintaining profitability.
• Sophisticated QoS-Integrated QoS and traffic-management capabilities based on Layers 2 through 4 classify and prioritize mission-critical and time-sensitive 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. The QoS mechanisms are delivered without performance impact.
• Predictable performance-The Cisco Catalyst 4500 Series offers up to a 72-million packets per second (mpps) wire-speed forwarding rate in hardware for traffic in Layers 2 through 4. Switching performance is independent of the number of route entries, QoS mechanisms enabled, and active VLANs. MANs need to respond reliably to meet end customer service-level agreements (SLAs).
• Advanced network security-The Cisco Catalyst 4500 Series supports up to 32,000 wire-rate Layer 2 through 4 access-list entries, Dynamic Host Configuration Protocol (DHCP) interface tracker (option 82) for subscriber tracking, DHCP snooping to prevent malicious or misconfigured DHCP servers, and includes other advanced security capabilities such as user authentication, client security, and control plane policing.
We prefer to ship UPS or FedEx, we also can ship DHL or US Postal Service. We can usually have it to your location overnight if needed. Additional Fee(s) may apply for special shipping. All equipment will ship from our warehouse located at our office in Springfield, MO. We can also ship overseas if needed and we only charge exact shipping costs. For most customers outside the USA and Canada, wire transfer is the only form of payment we will accept. Overseas customers can either arrange to have the equipment picked up in the USA or we will ship to your location by FedEx. We can also ship to a freight forwarder here in the USA. The purchaser will be required to pay for taxes and duties through customs in your home country.
