The Cisco 1921 Integrated Services Router offers embedded hardware encryption acceleration and advanced security services. In addition, the platforms support the industry's widest range of wired and wireless connectivity options such as Serial, T1/E1, xDSL, Gigabit Ethernet and third-generation (3G) wireless. 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).
The Cisco 1921 provides significantly enhanced modular capabilities that offer you investment protection. 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.
Service integration: The Cisco 1921 offers increased levels of services integration with data, security, wireless and mobility services, enabling greater efficiencies and cost savings
Services on demand: The Universal image contains all of the Cisco IOS Software technology sets that can be activated with a software license allowing your business to quickly deploy advanced features without downloading a Cisco IOS Software image
High performance with integrated services: The Cisco 1921 enables deployment in high-speed WAN environments with concurrent services enabled up to 15 Mbps
Network agility: Designed to address customer business requirements, the Cisco 1921 with the modular architecture offers a performance range of modular interfaces and services as your network needs grow
Energy efficiency: Services integration and modularity on a single platform performing multiple functions optimizes raw-materials consumption and energy usage, High-efficiency power supplies are provided with each platform
Modular platform: 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 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 & VPN services (Both IPSec & SSL acceleration)
Integrated Gigabit Ethernet ports: All onboard LAN/WAN ports are 10/100/1000 Gigabit Ethernet routed ports
Innovative universal serial-bus (USB)-based console access: The traditional console and auxiliary ports are also available. You can use either the USB-based console or the RJ-45-based console port to configure the router
USB 2.0 ports: One high-speed USB 2.0 port is supported. The USB port enables another mechanism for secure-token capabilities and storage
Encapsulations: Ethernet, 802.1q VLAN, Point-to-Point Protocol, Multilink Point-to-Point Protocol, Frame Relay, Multilink Frame Relay, High-Level Data Link Control (HDLC), Serial (RS-232, RS-449, X.21, V.35 and EIA-530), Point-to-Point Protocol over Ethernet (PPPoE) and ATM
Traffic management: QoS, Class-Based Weighted Fair Queuing (CBWFQ), Weighted Random Early Detection (WRED), Hierarchical QoS, Policy-Based Routing (PBR), Performance Routing (PfR) and Network-Based Advanced Routing (NBAR)
WSMA: The Web Services Management Agent (WSMA) defines a mechanism through which you can manage a network device, retrieve configuration data information and upload and manipulate new configuration data
EEM: Cisco IOS EEM is a distributed and customized approach to event detection & recovery offered directly in a Cisco IOS Software device. It offers the ability to monitor events & take informational, corrective, or any desired EEM action when the monitored events occur / when a threshold is reached
IPSLA: Cisco IOS IP SLAs enable you to assure new business-critical IP applications, as well as IP services that use data, voice and video, in an IP network
SNMP, RMON, Syslog, NetFlow and TR-069: Cisco 1921 Integrated Services Routers also support SNMP, Remote Monitoring (RMON), syslog, NetFlow andTR-069 in addition to the embedded management features previously mentioned
Cisco Enhanced High-Speed WAN Interface Card (EHWIC): The EHWIC slot replaces the high-speed WAN interface card (HWIC) slot and can natively support HWICs, WAN interface cards (WICs) and voice/WAN interface cards (VWICs)
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
Investment protection: Reuse of a broad array of existing modules supported on the original integrated services routers (ISRs) provides a lower TCO. A rich set of Cisco IOS Software features is carried forward from the original ISRs and delivered in the universal image
