mix together
In today's competitive business environment, converged networks can improve productivity and organizational flexibility and reduce operating costs, thus helping organizations to enhance their competitive advantages. Integrating data, voice and video into the same IP network, such as unified communication, requires the switching infrastructure to distinguish various traffic types and manage them according to their unique requirements. Cisco Catalyst 4500 series provides a switching infrastructure similar to Cisco IOS&; Reg In a word, software can provide advanced uninterrupted service and control.
Safe and uninterrupted service
Cisco Catalyst 4500 Series provides network infrastructure for all applications that solve business problems through integration. If the intelligent network service can be extended through integrated sustainability, it will be able to effectively control all kinds of traffic and only need a short planned and unplanned downtime. Cisco Catalyst 4500 provides this control in the following ways:
Sustainability of integration: Cisco Catalyst 4500 series is due to its redundant management engine (failover in one second) function (Cisco Catalyst 4507R-E and 45 10R-E switches), advanced fault-tolerant software, full-image uninterrupted software upgrade service (ISSU), redundant fans and 1+ 1 redundant power supply. In addition, all Cisco Catalyst 4500 series chassis adopt integrated power over Ethernet (PoE), which simplifies the design and reduces the number of failure points of unified communication.
Advanced security: Support the patented Cisco L2 security function, and help prevent attacks from malicious servers and "man-in-the-middle" attacks by intercepting passwords and data. In addition, in order to eliminate the traffic generated by malicious network attackers, L2-L4 filtering and speed limitation are also supported.
Advanced QoS: With the help of modular QoS CLI(MQC) and up to 64,000 QoS policy items, integrated QoS and traffic management functions based on L2-L4 can identify and give priority to critical business and time-sensitive traffic. Cisco Catalyst 4500 series can promote the integration and speed limit of bandwidth-intensive traffic according to the mechanism of input and output speed limiter of host, network and application information.
Comprehensive management: Cisco Catalyst 4500 series provides web-based management for the configuration and control of all ports, so as to centrally manage key network characteristics, such as availability and responsiveness.
Extensible architecture
Because convergence eliminates independent voice, video and data infrastructure, it reduces the total cost of network ownership and simplifies management and maintenance. The modular architecture of Cisco Catalyst 4500 series is highly scalable and flexible, and there is no need to deploy multiple platforms, thus reducing the maintenance cost. To further extend the customer's network equipment deployment cycle, Cisco Catalyst 4500 series provides the following features:
Backward compatibility of line cards: After upgrading to the new management engine, customers can flexibly reuse the original line cards or upgrade to higher performance line cards without changing the whole system, thus delaying the time of capital investment.
Smooth technology migration: customers can smoothly migrate to line-speed IPv6 or 10 Gigabit Ethernet according to their own progress. Deploying IPv4 and IPv6 to any number of IPv6 paths at the same time will not affect the line-speed routing capability of the whole system. E-series management engine and TwinGig converter and X2 module supported by 10 Gigabit E-series line card enable customers to improve network performance from Gigabit Ethernet to 10 Gigabit Ethernet without upgrading management engine or line card.
Leave room for future functions: Cisco Catalyst 4500 series architecture is equipped with a lot of hardware resources to support future functions and meet users' future network needs. Just upgrade Cisco IOS software, you can give full play to the advantages of many hardware functions without upgrading the whole system.
Reduce power consumption: The power consumption of Cisco Catalyst 4500 series is very low because of its centralized hardware architecture design.

Redundancy management engine helps to shorten planned and unplanned network downtime and improve business continuity and employee productivity. Non-disruptive forwarding with state switching (NSF/SSO) can provide continuous packet forwarding during management engine switching. NSF/SSO can significantly improve the reliability and availability of the network in L2 or L3 environment. Full-mirror ISSU provides rapid software upgrade for new line cards, new power supplies, new functions or defect repair, without affecting the routing process or making the network unstable. Even if the Cisco IOS software image is being upgraded or downgraded, IP voice will not be discarded. NSF/SSO and ISSU are very important for key business applications such as voice over IP (VoIP).
