Cisco 2800 Series Integrated Services Routers [Cisco 2800 Series Integrated Services Routers]

General

Q. What are the Cisco® 2800 Series Integrated Services Routers?

A. The Cisco 2800 Series comprises four new platforms: the Cisco 2801, 2811, 2821, and 2851 Integrated Services Routers. 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 improvement in chassis performance, 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 Cisco 1700 Series Modular Access Routers, 2600 Series Multiservice Platform, 3700 Series Multiservice Access Routers, and 3800 Series Integrated Services Routers interface cards and modules.

The Cisco 2800 Series features fast, high-quality delivery of multiple, simultaneous services. Not only does the Cisco 2800 Series offer embedded encryption-acceleration and motherboard voice digital-signal-processor (DSP) slots, intrusion-protection and firewall functions, integrated call processing and voicemail, and high-density interfaces for a wide range of connectivity requirements, but it also offers sufficient performance and slot density headroom for future network expansion requirements and advanced applications.

The best-in-class Cisco 2800 Series architecture is specifically designed to meet the requirements of small and medium-sized businesses (SMBs), small and medium-sized enterprise branch offices, and service provider-managed services applications for concurrent services without compromise to router performance.

Q. Why did Cisco introduce the Cisco 2800 Series?

A. Cisco introduced the Cisco 2800 Series to allow the deployment of multiple integrated services running at wire speed, without compromising router performance. The integrated services router portfolio is specifically designed to provide excellent performance while running simultaneous services such as voice, security, quality of service (QoS), and other routing services in one integrated routing platform.

Q. What are the versions in the Cisco 2800 Series?

A. The Cisco 2800 Series includes the Cisco 2801, 2811, 2821, and 2851. The Cisco 2811, 2821, and 2851 share a single network module slot, four High-speed Wan Interface Card (HWIC) slots, and two advanced integration module (AIM) slots. The Cisco 2801 offers four interface card slots, where two of the four slots are HWIC slots; one slot is a WIC, voice WIC (VWIC), and voice interface card (VIC)-only slot; and the final slot is a voice-only VWIC/VIC slot. Additionally, the Cisco 2801 offers two AIM slots, but does not have network module slots. All versions have onboard hardware-based encryption for Digital Encryption Standard (DES), Triple DES (3DES), and Advanced Encryption Standard (AES) plus onboard slots for packet voice DSP modules (PVDMs), and they all include high-speed Ethernet interfaces. The Cisco 2801 supports two PVDMs and two Fast Ethernet connections, The Cisco 2811 also provides one single-width network module enhanced (NME) slot. The Cisco 2821 offers increased performance, support for an extended single-wide network module, an extension voice module (EVM) slot, support for a third PVDM, fixed LAN ports supporting Gigabit Ethernet, and support for up to 33 ports of Cisco Unified IP Phone power. The Cisco 2851 offers increased performance compared to the Cisco 2821, adds support for double-wide and extended double-wide network modules, and offers increased IP phone power support for up to 50 Cisco Unified IP Phones. Table 2 later in this documents provides a comparison of the Cisco 2800 models.

Q. What are the plans for Cisco 1700, 2600XM, and 3700 Series modular access routers?

A. Cisco 1700, 2600XM and 3700 Series modular access routers' end-of-sale date was March 27, 2007. Customers with active service contracts will continue to receive support from the Cisco Technical Assistance Center (TAC) until March 25, 2012. The exception is Cisco 2621XM-DC. This model is still orderable and there are presently no EoS plans for it. For more details on the Cisco end-of-life policy, see http://www.cisco.com/en/US/products/products_end-of-life_policy.html.

Q. How does the Cisco 2800 Series compare to the Cisco 2600XM multiservice access routers?

A. The Cisco 2800 Series routers are the follow-on platforms to the Cisco 2600XM Series. The Cisco 2800 Series offers up to a fivefold chassis performance improvement, twice the default memory, and dramatically increased slot performance and services density, while maintaining support for most of the more than 90 existing Cisco 1700 and 2600 Series interface cards and network modules (on the Cisco 2811, 2821, and 2851 only).

Q. What is the performance of the Cisco 2800 Series?

A. The Cisco 2800 Series of integrated services routers are designed to deliver multiple concurrent services at wire-speed performance up to multiple T1/E1/xDSL speeds. Chassis performance has been increased up to fivefold, and security and voice performance has been increased up to tenfold. The multiple T1/E1/xDSL value quoted here represents IMIX packet sizes in higher-than-typical Cisco 2800 Series services configurations. In less service-heavy environments, actual WAN throughput will be higher. Table 1 shows recommended performance levels for the Cisco 2800 Series.

Table 1. Cisco 2800 Series Performance

Platform	Recommended Performance with Services Enabled (IMIX traffic)
Cisco 2801	Up to 1 T1/E1/xDSL
Cisco 2811	Up to 2 T1/E1s/xDSL
Cisco 2821	Up to 4 T1/E1s/xDSL
Cisco 2851	Up to 6 T1/E1s/xDSL

Q. Does the Cisco 2800 Series support a T3/E3 interface?

A. The Cisco NM-1T3E3 is supported on the Cisco 2811, 2821 and 2851 platforms. This module provides customers with a connectivity option for a DS3 interface, but only at sub-line rates. As shown Table 1, the Cisco 2800 Series routers are designed to be T1/E1 routers, not DS3 routers. Although some customers may achieve line rate or near line rate on a DS3 with no services, the addition of common services such as access control lists (ACLs), quality of service (QoS), and IP Security (IPSec) will each cause performance degradation. The recommended platform for T3/E3 connectivity is the Cisco 3800 Series.

Q. What are the basic specifications for the Cisco 2800 Series?

A. Table 2 gives the specifications of the Cisco 2800 Series.

Applications

Q. What applications does the Cisco 2800 Series support?

A. The Cisco 2800 Series offers a comprehensive feature set ideal for applications and solutions requiring the following:

• Integrated services: With the optional integration of a wide array of services modules, the Cisco 2800 Series offers the capability to easily integrate the functions of standalone network appliances and components in a network-module form factor and support multiple services without compromising router performance. Many of these network modules, such as the network analysis, voicemail, intrusion-detection, and content-engine modules, have embedded processors and hard drives that allow them to run mostly independent of the router.

• Secure network connectivity for data, voice, and video: The Cisco 2800 Series features advanced integrated, end-to-end security for the delivery of converged services and applications. The integration of security functions directly onto the router provides optimal performance for security applications such as network admission control (NAC), Dynamic Multipoint VPN (DMVPN) solutions, IPv6 for Cisco IOS Software, dynamic intrusion protection systems, and transparent Cisco IOS Firewall.

• Converged IP Communications: Cisco Unified Communications Manager Express (CME) is an optional solution embedded in Cisco IOS Software that provides call processing for Cisco Unified IP Phones. This solution is ideal for customers with data connectivity requirements interested in deploying a converged IP telephony solution for up to 96 phones. Customers can securely deploy data, voice, and IP telephony on a single platform for their small offices, helping them streamline their operations and lower their network costs.

Q. Can the Cisco 2800 Series provide inline power to IP phones and other devices?

A. With the optional AC plus inline power supply, the Cisco 2800 Series can provide either IEEE 802.3af-compliant Power over Ethernet (PoE) or Cisco prestandard inline power to devices. The platform is capable of providing up to 15 watts per port, to a total power limit of 120 watts on the Cisco 2801, 160 watts on the Cisco 2811, 240 watts on the Cisco 2821, and 360 watts on the Cisco 2851.

Q. Can the Cisco 2800 Series support both Cisco inline power and IEEE 802.3af PoE devices at the same time?

A. Yes, the Cisco 2800 Series supports up to the maximum total power available per model.

Network Modules: NM, NME, NMD, NME-X, and NME-XD

Q. What is an NME?

A. The NME slot is the next generation of the network module in the Cisco 2800 Series. NMEs are supported on the Cisco 2811, 2821, and 2851 routers only. The NME is available in three form factors: The single-wide (NME) is available on the Cisco 2811, 2821, and 2851 routers, the extra-wide (NME-X) is supported on the Cisco 2821 and 2851 routers, and only the extra-double-wide (NME-XD) is supported on the Cisco 2851. The NME offers additional performance over the existing network modules, as well as improved density. NME slots are also engineered to provide IEEE 802.3af-compliant PoE as well as Cisco product-based inline power for IP telephones and Cisco Aironet® access points. The Cisco 2851 also supports current high-density services modules (HDSMs) in the NME slot.

Q. Does the Cisco 2801 support an NME slot?

A. No, the Cisco 2801 does not support an NM or NME slot. It provides four modular card slots to support combinations of HWICs, VWWIC, WICs, and VICs.

Q. Are there any available modules specifically designed to the NME specifications?

A. Yes, the Cisco EtherSwitch® Service Modules are the first modules to support the NME specifications. These modules provide enhanced throughput, denser chipsets, IEEE 802.3af-compliant PoE, and higher interface densities than previously available with the original-generation network modules. Additional NMEs will follow, providing more capabilities and services.

Q. Are NME and HWIC slots backward compatible?

A. Yes, you can use the current-generation network modules and WICs in the new slots, but they will not be able to take advantage of all the NME features. WICs, VWICs, and VICs are all supported in the HWIC slots.

Q. Is online insertion and removal (OIR) supported for modules in the NME and HWIC slots?

A. No, OIR of modules is not supported on the Cisco 2800 Series.

Q. Do the Cisco 2811, 2821, and 2851 support all the current network modules?

A. Most existing modules are supported by the Cisco 2800 Series. Refer to the Cisco 2800 Series data sheet for a detailed list of all supported modules.

Q. Which network modules are not supported on the Cisco 2811, 2821, and 2851?

A. Table 3 shows the network modules that the Cisco 2811, 2821, and 2851 routers do not support.

NM-2CE1B	NM-1A-OC3MM-1V

Q. Why are these network modules not supported on the Cisco 2811, 2821, and 2851 routers?

A. Many of these modules, such as the Primary Rate Interface (PRI) and ATM inverse-multiplexing-over-ATM (IMA) modules, have reached end-of-sale or have been replaced by newer modules that are supported. Others, such as the Fast Ethernet combination card (part number NM-xFExW) and OC-3 network modules (part number NM-1A-OC3), were not supported in the Cisco 2600 Series and are not supported on the Cisco 2811, 2821, and 2851 routers. Finally, some modules, such as the NM-2W, are no longer required because the Cisco 2800 Series has higher-density interfaces and slots. No functions have been removed by not supporting these modules.

Q. Why can some newer modules and cards not be configured with technology bundles?

A. Technology bundles are tied to a specific Cisco IOS Software release when they are created, and the Cisco IOS Software release is updated only periodically as the technology team deems necessary. To access the new interface cards, you need to upgrade the Cisco IOS Software to the required minimum version. On the Options tab of the configuration tools are new Cisco IOS Software upgrade options that allow you to both change the release of the bundle and upgrade the image.

Interfaces Cards: WICS, VWICS, and HWICS

Q. What is an HWIC?

A. The HWIC is an updated and enhanced version of the current WIC in the Cisco 2600 chassis. The HWIC offers greater speeds and higher port density than the current WIC. HWIC slots can support modules that provide both Cisco product-based in-line power and PoE. HWICs are available in two form factors: a single-wide form factor that takes up one slot and a double-wide form factor that takes up two slots. Note: Two HWIC slots can be combined into one bigger slot (HWIC-D) by removing the center rail between two individual slots. The Cisco 2811, 2821, and 2851 routers can support four single-wide, the Cisco 2801 router can support two single-wide, and all versions can support two double-wide HWICs.

Q. Is OIR supported for modules in the HWIC slots?

A. No, OIR of modules in the HWIC slots is not supported.

Q. Does the Cisco 2800 Series support all the current WICs?

A. Most existing modules are supported in the Cisco 2800 (refer to the Cisco 2800 Series data sheet for a detailed list of all supported modules).

Q. Which WICs are not supported in the Cisco 2800 Series?

A. The WICs listed in Table 4 have been replaced with newer versions that provide the same or increased functions.
