Why Check Cisco EOL and EOSL Dates Regularly?
Tracking lifecycle milestones helps you maintain security, continuity, and predictable budgets across your Cisco infrastructure.
Security risks & patch coverage
Unsupported devices stop receiving firmware, bug fixes, and security updates. Regularly reviewing EOL/EOSL dates helps you retire or replace high-risk hardware before it becomes a security gap.
Maintenance & replacement planning
Knowing lifecycle milestones in advance lets you schedule hardware refresh without downtime, evaluate successor models, and coordinate maintenance windows with your operations team.
Budget & upgrade strategy
Align refresh cycles with finance plans instead of reacting to sudden failures. A clear EOL/EOSL roadmap helps you spread investments over time and avoid last-minute, unplanned replacement costs.
Cisco End-of-Life (EOL) & End-of-Service (EOS) Policy Overview
Layer23-Switch.com provides this summary based on the official End of Life (EOL) policy published by Cisco . The goal is to help users clearly understand lifecycle milestones, support timelines, and the transition process as products move toward EOL and End of Service Life (EOSL).
| Milestone | Description | Typical Duration |
|---|---|---|
| End-of-Life (EOL) Announcement | Cisco officially announces the product’s end-of-sale and end-of-support schedule. Replacement recommendations are often included in the notice. | 0 Months (Announcement Date) |
| End-of-Sale (EOS) | The last date to order the product from Cisco through authorized partners. After this date, it is no longer sold. | ~6 Months after EOL Announcement |
| Last Ship Date | The final date that Cisco ships the product to customers. Any pending orders must be fulfilled by this date. | ~12 Months after EOL Announcement |
| End of SW Maintenance | The last date Cisco releases software maintenance updates or patches (excluding critical security fixes). | ~24 Months after EOL Announcement |
| End of Service Contract Renewal | The final date customers can renew support or service contracts for the product. | ~36 Months after EOL Announcement |
| Last Date of Support / EOSL | Technical support and hardware repair services end. Cisco no longer provides software updates or TAC assistance. | ~60 Months after EOL Announcement |
Why Cisco EOL Policy Matters
Cisco ’s structured EOL process ensures long-term product stability and predictable lifecycle transitions. Customers can continue to receive support and software updates for years after the product’s end-of-sale date.
Planning for Replacement
To avoid service interruptions, review official EOL bulletins and migrate to newer models well before the EOSL date.
