Cisco End-of-Life Explained

Eight milestone dates. One that actually matters.

Last reviewed

Cisco's product lifecycle includes more named milestones than any other networking vendor. A single end-of-life bulletin can list 8+ dates spanning a 5-year window. Most network teams track the wrong one. The date that matters for security is End of Vulnerability/Security Support. The date that matters for operations is Last Date of Support. Everything else is procurement or maintenance housekeeping.

The milestones

Every Cisco EOL bulletin follows the same structure, in this order:

  1. End-of-Life Announcement Date — the bulletin is published. This is the starting gun.
  2. End-of-Sale Date — last day to order. Typically 30–90 days after announcement.
  3. Last Date of Warranty Renewal — last day to renew or extend a service contract.
  4. End of Software Maintenance — no more bug fixes. Security-only releases may continue.
  5. End of Routine Failure Analysis — Cisco stops analyzing hardware failures for root cause.
  6. End of New Service Attachment — last day to attach a new service contract to existing hardware.
  7. End of Vulnerability/Security Support — no more security patches or PSIRT advisories. This is the critical date for most networks.
  8. Last Date of Support — all support ends. No TAC, no RMA, nothing.

The timeline

Cisco's standard lifecycle from End-of-Sale to Last Date of Support is approximately 5 years. The End of Vulnerability/Security Support date typically falls about 3 years after EOS. That leaves a roughly 2-year window where Cisco will still honor your SmartNet contract for RMA and TAC access, but will not issue security patches.

This 2-year gap is the most misunderstood part of Cisco's lifecycle. Having an active SmartNet contract does not mean the device is receiving security updates. After the End of Vulnerability/Security Support date, you're paying for hardware replacement and phone support on firmware that will never be patched.

Which date to track

For security and compliance: End of Vulnerability/Security Support. After this date, the device is unpatched and PSIRT stops issuing advisories for it.

For hardware operations: Last Date of Support. After this date, SmartNet is no longer available and Cisco will not RMA the hardware.

For procurement: End-of-Sale Date. Place last-time-buy orders (spares, expansion modules) before this date.
