ISR4461-V/K9 - Cisco 4000 Family Integrated Services Router

ISR4461-V/K9 Exact Bundle Identity

ISR4461-V/K9 is the Cisco ISR 4461 Unified Communications bundle. The base hardware is the ISR 4461 branch router with two 10-Gigabit Ethernet and four 1-Gigabit Ethernet interfaces, three NIM slots and three service-module slots.

Bundle and performance boundary

Licensed bundle: V bundle: PVDM4-64, UC license and CUBE-25 according to Cisco's affected-PID table. Platform performance: 1.5 Gbps base platform performance, upgradeable to 3 Gbps with the documented performance license. Performance-license values are platform limits, not a promise of application throughput in every configuration.

Large-branch voice and capacity gate

Verify the PVDM4-64, CUBE-25 entitlement state, installed memory, power configuration and every NIM or service module. Size concurrent calls, transcoding, WAN throughput and redundancy separately. The bundle description does not include carrier service, SIP trunks, endpoints or unlimited CUBE capacity.

Lifecycle and migration

Cisco lists ISR4461-V/K9 as end of sale; the platform notice identifies 31 October 2029 as the last date of support. Cisco Catalyst C8300-2N2S-4T2X is the published migration product. 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.
