Lifecycle policy overview

Cisco End-of-Life Policy Overview

Cisco EOL notices normally break a product retirement into several planning dates, from the public announcement through the final support milestone. Use this page to confirm the exact part number before making refresh, support-renewal, or spare-unit decisions.

1

Announcement

Cisco publishes the retirement notice and the affected product IDs.

2

End of Sale

The normal order window closes for the listed product or license.

3

Service Windows

Maintenance, new service attachment, and renewal dates can close before final support.

4

Last Support

The last support date is the practical EOSL milestone for most planning work.
