Architecture and Modularity
The Cisco 1921 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 PoE and Cisco Enhanced PoE
(ePoE). Table 2 lists the architectural features and benefits of the Cisco 1921.
Table 2.
Architectural Features and Benefits
Architectural Feature
Modular platform
● The Cisco 1921 ISRs are highly modular platforms with multiple module slots to provide connectivity and services for
varied branch-office 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.
● The Cisco 1921 is powered by high-performance multicore processors that support growing demands of branch-office
networks by supporting high-throughput WAN requirements.
Embedded IP
Security/Secure Sockets
Layer (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.
Integrated Gigabit
Ethernet ports
● All onboard WAN ports are 10/100/1000 Gigabit Ethernet WAN-routed ports.
Innovative universalserial-bus (USB)-based
console access
● A new, innovative, mini-Type B USB console port supports management connectivity when traditional serial ports are
not available.
● The traditional console and auxiliary ports are also available. You can use either the USB-based console or the RJ45-based console port to configure the router.
Optional external power
supply for distribution of
● An optional upgrade to the power supply provides inline power (802.3af-compliant PoE and Cisco Standard Inline
Power to optional integrated switch modules.
Modularity Features and Benefits
The Cisco 1921 provides significantly enhanced modular capabilities (refer to Table 3) that offer you investment
protection. Most of the modules available on previous generations of Cisco routers, such as the Cisco 1841 ISR, are
supported on the Cisco 1921. Additionally, you can easily interchange modules used on the Cisco 1921 with other
Cisco routers to provide maximum investment protection. Taking advantage of common interface cards across a
network greatly reduces the complexity of managing inventory requirements, implementing large network rollouts,
and maintaining configurations across a variety of branch-office sizes.

Cisco IOS Software Licensing and Packaging
A single Cisco IOS Universal image encompassing all functions is delivered with the platforms. 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.
Four major technology licenses are available on the Cisco 1921 Integrated Services Routers; you can activate the
licenses through the Cisco software activation process identified at
IP Base: This technology package is available as default
Security (SEC) or Security with No Payload Encryption (SEC-NPE)

Mobility Services
Wireless WAN
Cisco 3G wireless WAN (WWAN) modules combine traditional enterprise router functions such as remote
management, advanced IP services such as voice over IP (VoIP), and security, with mobility capabilities of 3G WAN
access. Using high-speed 3G wireless networks, routers can replace or complement existing landline infrastructure,
such as dialup, Frame Relay, and ISDN. Cisco 3G solutions support 3G standards High-Speed Packet Access
(HSPA) and Evolution Data Only/Evolution Data Optimized (EVDO), offering you a true multipath WAN backup and
the ability to rapidly deploy primary WAN connectivity. For more information about 3G solutions on Cisco Integrated
Services Routers, please visit
Integrated LAN Switching
The Cisco 1921 Integrated Services Router will support the EHWIC LAN modules when they become available in the
future. The Cisco 1921 supports the existing singlewide Cisco EtherSwitch HWIC and the doublewide HWIC-D
modules, which greatly expand the capabilities of the router by integrating industry-leading Layer 2 switching.
Managing Your Integrated Services Routers
Network management applications are instrumental in lowering operating expenditures (OpEx) while improving
network availability by simplifying and automating many of the day-to-day tasks associated with managing an end-toend network. “Day-one device support” provides immediate manageability support for the ISR, 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 ISR. The new ISRs continue a tradition of broad and deep manageability features within the devices. Features
such as Cisco IOS IP Service-Level Agreements (IP SLAs), Cisco IOS Embedded Event Manager (EEM), and
NetFlow allow you to know what is going on in your network at all times. These features along with Simple Network
Management Protocol (SNMP) and syslog support enable your organization’s management applications.
