Why Check Cisco EOL and EOSL Dates Regularly?

Tracking lifecycle milestones helps you maintain security, continuity, and predictable budgets across your Cisco infrastructure.

01

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.

02

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.

03

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.
