1-16 Chapter 1: Routing

Key Features and Benefits

The Cisco 1900 Series is architected to meet the application demands of today's branch offices with design

flexibility for future applications. The modular architecture is designed to support expanding customer

requirements, increased bandwidth, and fully integrated power distribution to modules supporting 802.3af

Power over Ethernet (PoE) and Cisco Enhanced PoE (ePoE).

Key architectural features include:

•Modular platform

- The Cisco 1900 Series ISR are highly modular platforms with multiple module slots to provide

connectivity and services for varied branch network requirements.

- The ISRs offer an industry-leading breadth of LAN and WAN connectivity options through modules to

accommodate field upgrades to future technologies without requiring replacement of the platform.

•Processors

- The Cisco 1900 Series is powered by high-performance multi-core processors that support growing

demands of branch office networks by supporting high throughput WAN requirements.

• MultiGigabit fabric

- The Cisco 1941 model in the Cisco 1900 Series introduces an innovative MultiGigabit Fabric (MGF)

which allows for efficient module to module communication, enabling direct services interactions across

modules while reducing the overhead on the router processor.

• Embedded IPSec/SSL VPN hardware acceleration

- Embedded hardware encryption acceleration is enhanced to provide higher scalability, which, combined

with an optional Cisco IOS Security license, enables WAN link security and VPN services (Both IPSec

and SSL acceleration).

- The onboard encryption hardware out-performs the Advanced Integration Modules of previous

generations.

- The routers support Cisco Easy VPN (remote and server), Dynamic Multipoint VPN (DMVPN), Group

Encrypted VPN (GET VPN), and Secure Socket Layer VPN (SSL VPN).

- More than 3700 intrusion-prevention-system (IPS) signatures are supported in Cisco IOS Software, with

the ability to load and enable selected IPS signatures.

- Content Filtering includes URL/keyword blocking and features category-based productivity and security

ratings. This is a subscription-based hosted solution that leverages Trend Micro's global TrendLabs™

threat database, and is closely integrated with Cisco IOS Software.

- Cisco Configuration Professional comes standard on all Cisco 1900 Series Integrated Services Routers.

• Integrated Gigabit Ethernet Ports

- All onboard WAN ports are 10/100/1000 Gigabit Ethernet WAN routed ports.

- Innovative universal-serial-bus (USB)-based console access

- A new, innovative, mini-B USB console port supports management connectivity when traditional serial

ports are not available.

- The traditional console and auxiliary ports are also available. Either the USB-based console or the RJ-45-

based console port can be used to configure the router.

• Optional power supply for distribution of power over Ethernet (PoE)

- An optional power supply (internal in Cisco 1941 and external in Cisco 1921) provides in-line power

(802.3af-compliant Power-over-Ethernet [PoE] and Cisco standard inline power) to optional integrated

switch modules.

• Integrated wireless LAN

- The Cisco 1941W offers a secure integrated access point in a single device.

- Integrated access point is based on the IEEE 802.11n draft 2.0 standard that uses MIMO (Multi-Input,

Multiple-output) to improve coverage for existing 802.11a/ b/g clients and new 802.11n clients.

- The Cisco 1941W supports dual radios-802.11 b/g/n and 802.11a/n and is capable of operating in both

autonomous and unified modes.

• WAN Optimization with WAAS Express

- Cisco Wide Area Application Services (WAAS) Express, based on Cisco IOS Software and integrated into

the Cisco 1941 router offers bandwidth optimization and application acceleration capabilities in a cost-

effective solution

- Fully integrated in Cisco IOS Software, with no additional hardware requirement (the maximum DRAM is

needed in the router). This integration allows significant savings in capital expenditures (CapEx) by

enabling a small-footprint branch-office deployment.

- Increases remote user productivity, reduces WAN bandwidth costs, and offers investment protection by

interoperating with existing Cisco WAAS infrastructure.

- Uniquely provides network transparency, improving deployment flexibility with on-demand service

enablement, and integrating with native Cisco IOS Software services such as security, NetFlow, and

quality of service (QoS).

- Fully interoperable with Cisco WAAS Modules for Services-Ready Engine (SRE) and Cisco WAAS

appliances and can be managed by a common Cisco WAAS Central Manager.

- Offers Context-Aware DRE for reduced latency and increased end-user experience.

- Organizations can enable Cisco WAAS Express as an on-demand service on the router and can expand

to the Cisco WAAS Modules for SRE or a dedicated Cisco WAAS appliance as business needs grow.
