ISR4451-X-V/K9 Cisco ISR4451 UC Bundle Integrated Services Router
ISR4451-X-V/K9 Cisco ISR4451 UC Bundle Integrated Services Router
High-Performance Integrated Services Router with Unified Communications for Branch Deployments
The Cisco ISR 4451-X Integrated Services Router (ISR4451-X-V/K9) is a high-performance, modular enterprise WAN edge router designed for large branches and campus offices that require fast connectivity, advanced security, and integrated unified communications. Built on Cisco IOS XE, the ISR 4451-X consolidates routing, security, voice, and application services into a single, scalable platform - reducing complexity while improving performance.
With throughput up to 2 Gbps (performance license enabled) and a multi-core processor with hardware-based crypto acceleration, the ISR 4451-X delivers reliable, low-latency WAN performance for demanding workloads. The router features four integrated Gigabit Ethernet ports, two SM-X service module slots, and two NIM slots, providing flexible expansion for WAN interfaces, security, and application services.
Security is comprehensive and enterprise-grade, including Zone-Based Firewall, IPsec/SSL VPN, Cisco TrustSec, and integration with Cisco Identity Services Engine (ISE). Advanced routing capabilities - BGP, OSPF, EIGRP, RIP, MPLS, and NAT - support complex network designs, while advanced QoS ensures prioritization for voice and video traffic.
The ISR 4451-X also excels in collaboration use cases. With support for Cisco Unified Communications Manager Express (CME), SRST, PVDM3 DSP modules, and Cisco Unified Border Element (CUBE), it functions as a high-density voice gateway for resilient branch communications. Optional redundant power supplies, robust cooling, and rich management options (Cisco Prime, Web UI, CLI, SNMP, NetFlow) make it a dependable choice for always-on operations.
