Introduction

This product bulletin describes the support timeline and End-of-Life (EoL) guidelines for Cisco IOS XE Software.

Cisco IOS XE Software Release Model

The Cisco IOS XE 16.x.x and 17.x.x Software releases are time-based, each with a fixed release date. The schedule specifies 3 individual software releases per year at 4 month intervals.

Cisco IOS XE Software Support

Each Cisco IOS XE software release is classified as either a Standard-Support release or an Extended-Support release.

      Standard-Support Release Details

    A sustaining support lifetime of 12 months from First Customer Shipment (FCS) with scheduled rebuilds.

      Extended-Support release Details

    A sustaining support lifetime of 36 months from First Customer Shipment (FCS) with scheduled rebuilds.

Cisco makes no commitment to introduce software fixes to the affected IOS XE Software release after the final planned rebuild release.

Optional Rebuilds

Software problems found after the final scheduled rebuild release will be fixed in a subsequent major Cisco IOS XE Software release. An exception may arise to address mission-critical, high-severity software fixes and security vulnerabilities, possibly resulting in an additional rebuild release, after the final scheduled rebuild date (but before the End-of-Software Maintenance milestone), on an as-needed basis at the discretion of Cisco. No software fixes will be introduced to the affected Cisco IOS XE Software release after the End-of-Vulnerability and Security (EoVS) milestone.

After EoVS, Cisco Technical Assistance Center (TAC) will provide customer support on the affected Cisco IOS XE Software release, within the guidelines set by existing Cisco’s EoL policies, at the End-of-Software Maintenance milestone.

Cisco IOS XE Software Release Schedule

Cisco IOS XE Software Release 16.9 is the first Extended-Support release under the 16.x series to support 36 months and Cisco IOS XE Software Release 17.3 is the first Extended-Support release under the 17.x series. Every subsequent third release (for example, Cisco IOS XE Software releases 16.12, 17.6, 17.9 etc.) will also be an Extended Maintenance release. Table 1 below defines the support models used by each of the Cisco IOS XE Software releases.

End-of-Sale and End-of-Life Guideline Definition

The Cisco IOS XE Software End-of-Sale (EoS) and End-of-Life (EoL) guidelines have preset time intervals for each of the EoL milestones. These time intervals are based on the support model of the affected Cisco IOS XE Software version. Table 2 below summarizes the End-of-Sale (EoS) and End-of-Life (EoL) milestones for Cisco IOS XE Software releases.
