商品描述

Benefits Easily grow your branch offices with these industry-leading router capabilities:

• Networking, services, computing, and storage integrated into a single form factor

• Consistent, gigabit performance while multiple services run concurrently

• Modular Cisco IOS® XE Software, which quickly adapts to changing needs

• Integrated Cisco Intelligent WAN features, including application awareness, quality of service, and WAN optimization

• SDN-based automation of IWAN feature configuration with IWAN app

• Pervasive security with VPN options, threat defense services, and consistent policy enforcement

• Trust Anchor Technologies, protecting against modern cyberattacks, as well as counterfeit and unauthorized modification of hardware and software

• A range of WAN access connectivity options such as 4G LTE, T1/E1, T3/E3, xDSL, serial, and fiber Gigabit Ethernet

Auto-configuration of Cisco Intelligent WAN features helps deliver software-defined widearea networking (SD WAN) to enterprise networks.

The platform is modular and upgradable, so you can add new services without changing equipment. It supports multiple application-aware services concurrently while maintaining WAN performance of up to 2 Gbps, even during heavy traffic loads. The backplane architecture supports high-bandwidth, module-to-module communication at speeds up to 10 Gbps. The 4000 Series includes Cisco Trust Anchor Technologies that help mitigate modern cyberattacks by verifying platform integrity and providing protection from counterfeit and unauthorized modification of hardware and software.

Intelligent Services Reduce Bandwidth Costs

The 4000 Series runs Cisco Intelligent WAN (IWAN), a comprehensive set of traffic control and security features. With IWAN, you get all the business-grade capabilities of a Multiprotocol Label Switching (MPLS) VPN using other types of less-expensive links. You get per-application traffic management, WAN optimization, and VPN tunneling, for example, which you can put to work across Internet, cellular, and other lowercost services as you add connections. And you can activate new router services on demand through a simple licensing change. Remote application installation and management capabilities mean you don’t need local IT staff to deliver a fully comprehensive computing and networking experience in the branch. That comes in handy in new or smaller sites where you don’t have IT personnel already. All this plus convergence and stable, high-speed performance means you can now roll out your branch services at the speed of business.

Near-Instant IWAN Configuration

You can now configure your Cisco IWAN features in next to no time, thanks to Cisco’s enterprise software-defined networking (SDN) controller, the Application Policy Infrastructure Controller Enterprise Module (APIC EM). APIC EM allows you to automate lots of tasks across the network.

You can implement an SDN on your Cisco WAN infrastructure without having to upgrade your equipment; you just install the no-charge APIC EM software-based controller between your applications and network infrastructure. The controller translates business policy directly into network device-level policy for automatic compliance with your corporate and industry-mandated polices. For additional WAN management simplicity, customers can also use the IWAN app for APIC EM. The app automates the configuration of Cisco Intelligent WAN features, such as quality of service (QoS), WAN optimization, and security, in Cisco branch and edge WAN routers. The app slashes what used to require 1000 command-line interface (CLI) steps to just 10 mouse clicks per site. With the IWAN app’s template functionality, the ability to configure, deploy, and manage large numbers of branch offices has never been easier.
