Overview of the Hardware and SoftwareThe Cisco 3900 series, Cisco 2900 series, and Cisco 1900 series integrated services routers (ISRs) offersecure, wire-speed delivery of concurrent data, voice, and video services. The modular design of theserouters provides maximum flexibility, allowing you to configure your router to meet evolving needs.The routers offer features such as hardware-based virtual private network (VPN) encryptionacceleration, intrusion-protection and firewall functions, and optional integrated call processing andvoice mail. A wide variety of legacy network modules and interfaces, service modules (SMs), internalservices modules (ISMs), next-generation packet voice/data modules (PVDM3), Services PerformanceEngines (SPEs), high-density interfaces for a wide range of connectivity requirements, and sufficientperformance and slot density for future network expansion requirements and advanced applications areavailable.Power-saving hardware and software features are incorporated throughout the series. These routersprovide access to the multi-gigabit fabric, which provides a connection between switch ports withoutusing up external ports. The logical Gigabit Ethernet (GE) interface on the router connects external andinternal modules through the backplane for LAN and WAN switching. Software feature upgrades areprovided through software licensing.The following sections describe the Cisco 3900 series, 2900 series, and 1900 series ISRs: Feature Information, page 2 New Features by Platform, page 4 New Slots, page 4 New Slots and Ports by Platform, page 5 Common Ports, page 6 Licensing, page 6 Getting Started, page 7Cisco 3900 Series, Cisco 2900 Series, and Cisco 1900 Series Integrated Services Routers Generation 2 Software Configuration Guide1

ChapterOverview of the Hardware and SoftwareFeature InformationFeature InformationTable 1Feature InformationFeatureDescriptionServices PerformanceEngineSPEs1 are modular motherboards on Cisco 3900 series ISRs. The SPEhouses PVDM3 slots, system memory slots, and the ISM slot. The SPEprovides a modular approach to system upgrades. You simply slide out theSPE from the router to replace internal modules, or upgrade the SPE toimprove router performance. See Cisco 2900 series and 3900 seriesIntegrated Services Routers Hardware Installation Guide for instructions.Cryptographic EngineAcceleratorCisco 3900 series routers with either Services Performance Engine 200 orServices Performance Engine 250 have an onboard cryptographicaccelerator that is shared between SSLVPN and IPSec. By default,acceleration of SSL is disabled so IPSec performance is maximized.See the “Configuring Security Features” section on page 123 in this guidefor information about enabling the SSLVPN feature.USB ConsoleCisco 3900 series, 2900 series, and 1900 series ISRs provide an additionalmechanism for configuring the system through a USB2 serial console port.The traditional RJ-45 serial console port is also available.Power ManagementSome modules and interface cards that are inserted in new slots providehardware and software power management features described below:Advanced CapabilityCompactFlash High efficiency AC power supplies Electrical components with built-in power saving features, such asRAM select and clock gating Ability to disable unused clocks to modules and peripherals Ability to power down unused modules and put peripherals into areset state, put front panel ports and unused internal components in ashutdown or reset stateCisco 3900 series, 2900 series, and 1900 series ISRs use AdvancedCapability CF3 memory to store the system image, configuration files, andsome software data files.SFP/Gigabit Ethernet Port Cisco 2921, Cisco 2951 and Cisco 3900 Series routers have anSFP/Gigabit Ethernet port that supports copper and fiber concurrentconnections. Media can be configured for failover redundancy when thenetwork goes down. For more information, see the “Configuring BackupData Lines and Remote Management” section on page 93.Cisco 3900 Series, Cisco 2900 Series, and Cisco 1900 Series Integrated Services Routers Generation 2 Software Configuration Guide2

ChapterOverview of the Hardware and SoftwareFeature InformationTable 1Feature Information (continued)FeatureDescriptionNew Modules andInterface CardsCisco 3900 series, 2900 series, and 1900 series ISRs introduce thefollowing new modules and interface cards, which are inserted in thefollowing new router slots: EHWIC PVDM3 ISM SMNoteSee the router’s product page at Cisco.com for a complete list ofsupported modules and interfaces.Multi-Gigabit FabricCommunicationCisco 3900 series, Cisco 2900 series, and Cisco 1900 series ISRs use aMGF4 for the new modules and interface cards to inter-communicate onthe router. Legacy modules that support Cisco HIMI5 also support MGFto inter-communicate on the router. Next generation module driversintegrate with the MGF to perform port configurations, configure packetflow, and control traffic buffering. All configurations are performed fromthe module-side, which may or may not lead to changes on the MGF. Formore information, see the “Configuring Multi-Gigabit FabricCommunication” section on page 207.Integrated ApplicationServices FeaturesCisco 3900 series, 2900 series, and 1900 series ISRs offer integratedsecurity features and voice features.

ChapterOverview of the Hardware and SoftwareIOS CommandsIOS CommandsTable 7 lists the Cisco IOS commands and features that can trigger an erase, write, or erase and writeoperation on a device's boot flash. The erase or write of an attribute on the boot flash can hold the CPUfor a few milliseconds to complete the operation. The CPU hold can result in a functional impact onprotocols or applications that are extremely time sensitive, for instance, Bidirectional ForwardingDetection (BFD) or routing protocols which use finely tuned short timers. For example, OSPF with fasthellos and short dead timers.Table 7Cisco IOS CommandsConfigurationExampleFunctionalityCommand NameDescriptionWrite to NVmemory.write memoryRouter#writeThis commandwrites the device's memoryconfiguration in tothe Non-VolatileRAM (NVRAM)on the boot flash.Use this commandin privilegedEXEC mode.A BFD flap is triggered when one of thefollowing configuration elements areactivated or deactivated and configuration issaved to memory:Router(config)#The router has aconfig-register16-bit0xvalueconfigurationregister inNVRAM.
