DATA SHEET
CISCO 2800 SERIES INTEGRATED SERVICES ROUTERS
Cisco Systems®, Inc. is redefining best-in-class enterprise and small- to- midsize business routing with a new line of
integrated services routers that are optimized for the secure, wire-speed delivery of concurrent data, voice, and video
services. Founded on 20 years of leadership and innovation, the Cisco® 2800 Series of integrated services routers (refer
to Figure 1) intelligently embed data, security, and voice services into a single, resilient system for fast, scalable delivery
of mission-critical business applications. The unique integrated systems architecture of the Cisco 2800 Series delivers
maximum business agility and investment protection.
Figure 1. Cisco 2800 Series
PRODUCT OVERVIEW
The Cisco 2800 Series comprises four new platforms (refer to Figure 1): the Cisco 2801, the Cisco 2811, the Cisco 2821, and the Cisco 2851.
The Cisco 2800 Series provides significant additional value compared to prior generations of Cisco routers at similar price points by offering up
to a fivefold performance improvement, up to a tenfold increase in security and voice performance, new embedded service options, and
dramatically increased slot performance and density while maintaining support for most of the more than 90 existing modules that are available
today for the Cisco 1700, Cisco 2600, and Cisco 3700 Series.
The Cisco 2800 Series features the ability to deliver multiple high-quality simultaneous services at wire speed up to multiple T1/E1/xDSL
connections. The routers offer embedded encryption acceleration and on the motherboard voice digital-signal-processor (DSP) slots; intrusion
prevention system (IPS) and firewall functions; optional integrated call processing and voice mail support; high-density interfaces for a wide
range of connectivity requirements; and sufficient performance and slot density for future network expansion requirements and advanced
applications.

Secure Networking–Feature and Benefits
The Cisco 2800 Series features enhanced security functionality as shown in Table 3. Integrated on the motherboard of every Cisco 2800 Series
router is hardware-based encryption acceleration that offloads the encryption processes to provide greater IPsec throughput with less overhead
for the router CPU when compared with software-based solutions. With the integration of optional VPN modules (for enhanced VPN tunnel
count), Cisco IOS Software-based firewall, network access control, or content-engine network modules, Cisco offers the industry’s most robust
and adaptable security solution for branch-office routers.

Benefit
• Sophisticated security and policy enforcement provides features such as stateful, application-based filtering
(context-based access control), per-user authentication and authorization, real-time alerts, transparent firewall,
and IPv6 firewall.
• The Cisco 2800 Series supports IPsec Digital Encryption Standard (DES), Triple DES (3DES), Advanced
Encryption Standard (AES) 128, AES 192, and AES 256 cryptology without consuming an AIM slot.
• A Cisco Self-Defending Network initiative, NAC seeks to dramatically improve the ability of networks to
identify, prevent, and adapt to threats by allowing network access only to compliant and trusted endpoint
devices.
• The Cisco 2800 Series supports specific provider edge functions plus a mechanism to extend customers’
MPLS VPN networks out to the customer edge with virtual routing and forwarding (VRF) firewall and VRF
IPsec. For details on the MPLS VPN support on the different versions of the Cisco 2800 Series, please check
the feature navigator tool on www.cisco.com.
• The USB port(s) will be used for future capabilities and will initially support secure token and flash memory
• Support for an optional dedicated security AIM can deliver 2 to 3 times the performance of embedded
encryption capabilities with Layer 3 compression.
• Flexible support is offered through Cisco IOS® Software or a high-performance intrusion-detection-system
(IDS) network module.
• The ability to load and enable selected IDS signatures in the same manner as Cisco IDS Sensor Appliances
• The Cisco 2800 Series eases administration and management of point-to-point VPNs by actively pushing new
security policies from a single headend to remote sites.
• DMVPN is a Cisco IOS Software solution for building IPsec + generic routing encapsulation (GRE) VPNs in an
easy and scalable manner.
• URL filtering is available onboard with an optional content-engine network module or external with a PC server
running the URL filtering software.
• This intuitive, easy-to-use, Web-based device-management tool is embedded within the Cisco IOS Software
access routers; it can be accessed remotely for faster and easier deployment of Cisco routers for both WAN
access and security features.
