About the Cisco ISR 3800 CISCO3845 Cisco Integrated Services Router (ISR)
The Cisco ISR 3800 Series Integrated Services Router (ISR) is a 2U rack-mountable routing platform built on Cisco IOS, designed to consolidate WAN connectivity, security, and application services at branch and small campus locations. Network engineers and IT procurement teams rely on the CISCO3845 model to deliver secure, scalable routing with integrated encryption and multi-protocol support across complex enterprise networks.
This platform offers exceptional modularity and extensibility through 4 WAN Interface Card (WIC/HWIC) slots, 2 Network Module slots, and 2 Advanced Integration Module (AIM) slots—enabling organizations to customize interfaces and services without full platform replacement. The router includes 2 built-in Gigabit Ethernet LAN ports, integrated hardware-accelerated encryption (AES and 3DES), and support for multiple VPN technologies including IPsec, GRE, DMVPN, and GET VPN. Hardware-based QoS capabilities—including CBWFQ, LLQ, traffic shaping, and policing—ensure optimal application performance. Routing flexibility spans industry-standard protocols: BGP, OSPF, EIGRP, IS-IS, RIP, and static routing. A single CompactFlash slot provides onboard storage for IOS images and configuration files, while dual USB 1.1 ports and dedicated management interfaces (RJ-45 serial console and auxiliary port) support operational tasks. The integrated AC power supply includes optional redundant power supply support for mission-critical deployments.
