CISCO 2811 DATASHEET PDF

It provides Web routing for mostly small and medium businesses. Cisco A side-by-side comparison with previous routers manufactured by Cisco shows that the provides five times the performance and ten times the security that previous models had. Density and slot performance were boosted from previous designs. It offers wire speed performance to allow services, such as voice and security, to run concurrently. Better modularity and performance allowed the device to provide better service to businesses and organizations.

SM-Ds in the Cisco and provide flexibility for higher-density modules. Full EnergyWise support will be available in future software releases.

Each slot can support high-speed storage densities upgradeable to 4 GB in density. USB 2. Release New innovations in You can enable advanced features by activating a software license on the Universal image. In previous generations of access routers, these feature sets required you to download a new software image.

Technology packages and feature licenses, enabled through the Cisco software licensing infrastructure, simplify software delivery and decrease the operational costs of deploying new features. At each stage in the product lifecycle, Cisco ONE Software helps make buying, managing, and upgrading your network and infrastructure software easier. Key Branch-Office Services The Cisco Integrated Services Routers are industry-leading platforms that offer unprecedented levels of services integration. Designed to meet the requirements of the branch office, these platforms provide a complete solution with voice, video, security, mobility and application services.

Businesses enjoy the benefit of deploying a single device that meets all their needs, reducing capital and operational expenses. With embedded voice services and a wide range of supported telephony interfaces, the Cisco Series delivers maximum deployment flexibility for the distributed enterprise.

The new PVDM3 modules support all voice-gateway functions of earlier generations of PVDMs and add higher density and more processing power to support emerging rich-media applications. Cisco Unified Border Element The Cisco Unified Border Element capabilities supported on the Cisco Series address the emerging requirements in an IP-centric interconnect for branch-office unified communications between enterprises and service provider networks.

Cisco Unified Border Element provides intelligent border-element functions such as physical and logical ingress and egress demarcation points, signaling and media control, and consolidated security and management features. The Cisco Series supports higher scale than previously provided on the Cisco Series, up to three times the number of sessions.

The Cisco IOS Software Security technology package for the Cisco Series offers a wide array of common security features such as advanced application inspection and control, threat protection, and encryption architectures for enabling more scalable and manageable VPN networks.

The Cisco Series offers onboard hardware-based encryption acceleration to provide greater IPSec throughput with less overhead for the route processor when compared with software-based encryption solutions. Using high-speed 3G wireless networks, routers can replace or complement existing landline infrastructure, such as dialup, Frame Relay, and ISDN. These technologies allow you to meet increased endpoint power requirements without increasing the total power consumption of the branch.

Application Services As organizations continue to centralize and consolidate their branch-office IT infrastructure in an effort to reduce cost and complexity, they are challenged to provide an excellent user experience, ensure continuous service availability, and deliver business-relevant applications when and where they are needed. To address these challenges, the Cisco Series provides the capability to host Cisco, third-party, and custom applications on a portfolio of high-performance Cisco Services Ready Engine SRE modules that transparently integrate into the router.

The modules have their own processors, storage, network interfaces, and memory that operate independently of the host router resources, helping to ensure maximum concurrent routing and application performance while reducing physical space requirements, lowering power consumption, and consolidating management. Application Acceleration The Cisco Series seamlessly combines industry leading security, IOS-based traffic control and visibility, with Cisco application acceleration solutions.

The user experience can be further enhanced through the addition of a Cisco WAAS Network Module which can be used to securely provide more advanced WAN optimization techniques such as TCP optimization, caching, compression, and application acceleration. The solution allows you to consolidate costly server, storage, and backup infrastructure into data centers while maintaining LAN-like service levels for remote users. The Service Module hardware offers up to a seven times performance improvement over the previous generation Network Modules and provides a multi-core x processor.

The SRE modules also support up to 1 terabyte of storage, RAID configurations, hardware-assisted virtualization and cryptography options.

The Cisco SRE module enables on-demand provisioning of branch-office applications on the Cisco Series platforms so that you can deploy the right application, at the right time, in the right place. The hardware and software decoupling provided by the service-ready deployment model enables applications to be provisioned on the module at the time of its installation or remotely anytime thereafter. The Service Ready Engine enables organizations of various sizes to future-proof their network by allowing them to quickly deploy new branch-office applications without deploying new hardware, reducing the cost of rolling out branch-office services.

WAAS Express Organizations today face several unique wide area network WAN challenges: the need to provide employees with constant access to centrally located information, the requirement to continuously back up and replicate mission-critical data to centrally managed data centers, the desire to provide satisfactory experience for IP phone and video communication, and the mandate to control bandwidth costs without sacrificing application availability and performance.

Medianet for ISRs As video becomes pervasive in an organization and more video devices are used, new demands are placed on the network. It can be challenging to accommodate video needs while reducing complexity, planning for capacity, and providing the best possible user experience. Smarter Network, Endpoints, and Services Traditional IP networks need to evolve to medianets to accommodate these changes. A medianet is an end-to-end IP architecture that helps to enable pervasive media experiences.

The medianet architecture includes a smarter network, smarter endpoints, shared media services, cloud services, and shared media services. More Medianet Benefits A medianet reduces total cost of ownership and scales video through features such as auto-configuration and media monitoring. At the same time, it helps to ensure a quality user experience while optimizing bandwidth use and efficiency. Managing Your Integrated Services Routers Network management applications are instrumental in lowering operating expenses OpEx while improving network availability by simplifying and automating many of the day-to-day tasks associated with managing an end-to-end network.

Day-one device support provides immediate manageability support for the Integrated Services Router, enabling quick and easy deployment, monitoring, and troubleshooting from Cisco and third-party applications.

Organizations rely on Cisco, third-party, and in-house developed network management applications to achieve their OpEx and productivity goals. Underpinning those applications are the embedded management features available in every Integrated Services Router. Refer to Tables 4 and 5 below for details about network management and manageability support on Cisco Series Integrated Services Routers.

Table 4. Encapsulation Ethernet, Table 5. It offers the ability to monitor events and take informational, corrective, or any desired EEM action when the monitored events occur or when a threshold is reached.
