HARDWARE, SUBSCRIPTION AND MIGRATION BOUNDARIES
Cisco ISR4321-DNA Bundle and Lifecycle Guide
Verify the ISR4321-DNA hardware and Cisco DNA subscription boundary, exact platform configuration, lifecycle dates and Cisco C8200 replacement path.
What ISR4321-DNA includes
ISR4321-DNA is a Cisco ISR 4321 platform Bundle with a Cisco DNA software subscription. It is not an a-la-carte DNA license and it is not interchangeable with hardware-only, security or unified-communications ISR4321 PIDs.

Checks before ordering legacy inventory
- Confirm that the quote identifies the ISR4321 hardware and the exact DNA subscription tier and term; the generic Bundle PID alone does not state the selected subscription term.
- Verify whether any NIM, memory, storage, power, rack or security-license option is required beyond the documented base configuration.
- Record Cisco's November 30, 2028 end-of-support date in the procurement risk assessment.
- For a new deployment, compare interfaces, software, throughput and migration requirements against Cisco's referenced C8200-1N-4T replacement.
- Do not transfer lifecycle or subscription assumptions from other ISR4321 suffixes to this exact DNA Bundle.
