ISR4451-X-AX/K9 Overview
ISR4451-X-AX/K9 Exact Bundle Identity
ISR4451-X-AX/K9 is the Cisco ISR 4451-X Application Experience bundle with APP and SEC licenses. The base hardware is the ISR 4451-X branch router with four onboard Gigabit Ethernet interfaces, three NIM slots, one ISC slot, two service-module slots, 8 GB flash, 2 GB data-plane DRAM and 4 GB control-plane DRAM.
Bundle and performance boundary
Licensed bundle: AX bundle: APP and SEC technology licenses; UC licensing and PVDM voice hardware are not part of the AX identity. Platform performance: 1 Gbps base platform performance, upgradeable to 2 Gbps with the documented performance license. Performance-license values are platform limits, not a promise of application throughput in every configuration.
Application-services chassis acceptance
Confirm the exact AX PID, installed memory, power-supply count, NIM and service-module inventory, and the state of the APP and SEC entitlements. The chassis can accept modular services, but this SKU does not prove that a specific WAN card, compute module, voice DSP, storage device or active support contract is present.
Lifecycle and migration
Cisco lists the ISR4451-X product line as end of sale with support ending 30 November 2028. A Catalyst C8300 platform should be evaluated against slot, performance and service-module requirements. Treat the replacement as a migration starting point: interface modules, voice resources, software features, rack power and configuration must be mapped rather than assumed compatible.
