Note: This product bulletin describes the new support timeline for Cisco IOS® XE releases starting with Cisco IOS XE Software Release 3.10S and later. For the support timeline of previous Cisco IOS XE Software releases, please refer to the guidelines here.

Revised: December, 2012

Introduction

This product bulletin describes the support timeline and end-of-life guidelines for Cisco IOS ® XE Software on the Cisco ® ASR 1000 Series Aggregation Services Router.
Cisco IOS XE Software is a time and feature based release. Consequently, these end-of-sale and end-of-life guidelines of the Cisco IOS XE Software differ from the guidelines of other traditional Cisco IOS Software releases. This product bulletin outlines these differences and describes the standard end-of-sale and end-of-life milestones.

Cisco IOS XE Software Release

The architecture of the Cisco ASR 1000 Series Aggregation Services Router is designed with In-Service Software Upgrade (ISSU) capabilities. End users can usually perform hitless software upgrades while the system is in service.
The Cisco IOS XE Software releases are time-based, each with a fixed release date, as opposed to a variable release date. The schedule specifies three individual software releases at 4-month intervals within a 12-month cycle.

Cisco IOS XE Software Support

Each Cisco IOS XE Software release is classified as either a Standard-Support or Extended-Support release. A Standard-Support release has a sustaining support lifetime of 18 months from first customer shipment (FCS) with three scheduled rebuilds. The timing of these rebuilds is typically released at 3-, 3-, and 6-month intervals after FCS of the affected Cisco IOS XE Software release.
The Extended-Support release provides a sustaining support lifetime of 48 months from FCS with eight scheduled rebuilds. The timing of these rebuilds is typically released at 3-, 3-, 4-, 4-, 4-, 6-, 6-, and 6-month intervals after FCS of the affected Cisco IOS XE Software release.
Cisco makes no commitment to introduce software fixes to the affected Cisco IOS XE Software release after the final planned rebuild release.
Software problems found after the final 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 milestone.
After the end-of-vulnerability and security milestone, the Cisco Technical Assistance Center (TAC) will provide customer support on the affected Cisco IOS XE Software release within the guidelines set by existing Cisco end-of-life policies at the end-of-software-maintenance milestone.

Cisco IOS XE Software Release Schedule

Cisco IOS XE Software Release 3.10S is the first Extended-Support release under the new support timeline. Every subsequent third release (for example, Cisco IOS XE Software Releases 3.13S, 3.16S, etc.) will also be Extended-Support releases. Table 1 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 and end-of-life guidelines have preset time intervals for each of the end-of-life milestones. These time intervals are based on the support model of the affected Cisco IOS XE Software version. Table 2 summarizes the end-of-sale and end-of-life milestones for Cisco IOS XE Software releases.

1An additional rebuild release may be released after the final rebuild date to address mission-critical, high-severity software fixes and security vulnerabilities (before the end-of-vulnerability and security date) on an as-needed basis at the discretion of Cisco Systems, Inc.

Cisco IOS XE Software Standard-Support Schedule
Cisco IOS XE Software Standard-Support releases will be supported for 18 months with three rebuilds. The timing of the rebuilds will be as follows: 3 months, 3 months, and 6 months. Following the third rebuild will be a 6-month phase of PSIRT. During the PSIRT phase, if it is deemed that a fourth rebuild is required, then a scheduled rebuild will occur at the end of the Cisco Product Security Incident Response Team (PSIRT) period (6 months from the third rebuild). Table 3 and Figure 1 show the Cisco IOS XE Software Standard-Support rebuild schedule.

During the PSIRT phase, if it is deemed that additional rebuilds are required, then a scheduled rebuilds will occur 6 months into the PSIRT phase, or another at the end of the PSIRT phase. If it is deemed that these additional rebuilds are not required, then there will not be additional rebuilds. Table 4 and Figure 2 show the Cisco IOS XE Software Extended-Support rebuild schedule.
