Cisco ISR 4400 EOL List

This table tracks end-of-life milestones for 70 Cisco ISR 4400 part numbers.

The Cisco ISR 4400 family has no single end-of-life date; milestones are set per part number, so use the table to find the exact SKU you operate. Across this series, EOSL dates range from 2026-11-30 to 2030-01-31. Open any part number for source details, replacement fields, and current availability options.
