Secure Network Connectivity for Data, Voice, and Video
Security has become a fundamental element of any network. Routers play an important role in any
network defense strategy because security needs to be embedded throughout the network. The
Cisco 1861 Integrated Services Router features advanced, integrated, end-to-end security for the
delivery of converged services and applications. With the optional Cisco IOS Software Advanced
IP Services feature set, the Cisco 1861 provides a robust array of common security features such
as a Cisco IOS Software Firewall, intrusion prevention, IPSec VPN, SSL VPN, advanced
application inspection and control, Secure Shell (SSH) Protocol Version 2.0, and Simple Network
Management Protocol Version 3 (SNMPv3) in one secure solution set. Additionally, by integrating
security functions directly into the router itself, Cisco can provide unique intelligent security
solutions other security devices cannot, such as Network Admissions Control (NAC) for antivirus
defense; Voice and Video Enabled VPN (V3PN) for quality of service (QoS) enforcement when
combining voice, video, and VPN; and Dynamic Multipoint VPN (DMVPN), Group Encrypted
Transport (GET) VPN, and Easy VPN for enabling more scalable and manageable VPN networks.
As Figure 4 demonstrates, a Cisco 1861 uniquely helps customers deliver concurrent, mission-
critical data, voice, and video applications with integrated, end-to-end security at wire-speed
performance.

LAN Switching
The Cisco 1861 Integrated Services Router has an integrated, managed Ethernet switch that
provides 8 ports of 10/100 PoE. Additionally, the system capacity can be expanded by connecting
the recommended Cisco Catalyst portfolio of switches.
