ISR4321-DNA - Cisco 4000 Family Integrated Services Router

ISR4321-DNA Exact Bundle Identity

ISR4321-DNA is the Cisco ISR 4321 hardware bundle with a Cisco DNA subscription. The base hardware is the ISR 4321 branch router with two onboard Gigabit Ethernet interfaces, two NIM slots, one ISC slot, 4 GB flash and 4 GB DRAM.

Bundle and performance boundary

Licensed bundle: DNA bundle: ISR4321 hardware plus a DNA subscription; the tier, term and current renewal status must be confirmed from the order record. Platform performance: 50 Mbps base platform performance, upgradeable to 100 Mbps with the documented performance license. Performance-license values are platform limits, not a promise of application throughput in every configuration.

Subscription identity before transfer

Separate the physical router from the subscription record. Confirm the DNA tier, subscription term, smart-account assignment, virtual account, software image, throughput license and renewal state before ordering. This PID alone does not establish that a historical subscription is transferable or still active.

Lifecycle and migration

Cisco lists ISR4321-DNA and the ISR4321 platform as end of sale with support ending 30 November 2028. Cisco Catalyst C8200-1N-4T is the published hardware 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.
