One high-speed USB 2.0 port is supported. The USB port enables another mechanism for secure-
token capabilities and storage.
Cisco IOS Software
The Cisco 1921 Integrated Services Routers deliver innovative technologies running on industry-leading Cisco
IOS Software. Developed for wide deployment in the world’s most demanding enterprise, access, and service
provider networks, Cisco IOS Software Releases 15M and T support a comprehensive portfolio of Cisco
technologies, including new functions and features delivered in Releases 12.4 and 12.4T, and new innovations
that span multiple technology areas, including security, high availability, IP Routing and Multicast, quality of
service (QoS), IP Mobility, Multiprotocol Label Switching (MPLS), VPNs, and embedded management.
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
