ISR4451-X-V/K9 Overview
ISR 4451-X Unified Communications Bundle
ISR4451-X-V/K9 is an exact Cisco order built on the ISR 4451-X with four onboard Gigabit Ethernet interfaces, three NIM slots, one ISC slot and two service-module slots. Bundle boundary: V identifies the unified-communications bundle; APP and SEC technology-package rights are not implied.
Platform performance boundary
1 Gbps default aggregate throughput, upgradeable to 2 Gbps with the documented performance license. This published aggregate value is a platform licensing boundary, not a guarantee for every mix of encryption, voice, application inspection or modular services.
Exact receiving evidence
Verify the installed PVDM, UC entitlement, voice-interface NIMs, CUBE/SRST/CME requirements and software compatibility. Record DSP utilization under representative call load instead of treating the V suffix as unlimited voice capacity.
Workload-specific migration record
Create a dial-plan acceptance pack with number ranges, translation rules, codecs, fax/modem behavior, emergency calling, survivability and carrier handoff. Preserve a rollback route for each trunk before moving voice services.
Lifecycle decision
Cisco ended sale for this ISR 4000 generation and publishes 30 November 2028 as the last date of support for the affected platform family. Treat the recommended Catalyst 8300 family as a redesign starting point: interface modules, service-module functions, licenses, throughput, power and configuration are not automatically portable.
Acceptance checklist
Record the exact PID and serial, chassis inventory, memory, flash, power supplies, installed NIM/ISC/service modules, software release, performance license and every active entitlement. Preserve the final test evidence and configuration backup with the asset record.
