Bias-Free Language

The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

    Introduction

    This document describes how to choose a stable Cisco IOS® XE release for enterprise routing platforms.  

    Background Information

    This document covers recommended releases for Catalyst 8000 Edge, ASR1000, ISR4000 and ISR1000 Platforms.

    The software versions provided in this document are generally considered stable for the majority of deployments. Before you select a release, review the associated Release Note document and verify there are no open caveats that can impact the device based on its configured features. The Release Notes also contain tables that identify when Rommon, Field-Programmable Gate Array (FPGA), or Complex Programmable Logic Device (CPLD) versions must be upgraded before you perform the Cisco IOS XE upgrade.

    Whenever possible, it is advised to install an Extended-Support release of Cisco IOS XE software. Where hardware support or support for a particular feature is not yet available in an Extended-Support release, a Standard-Support release is required. When the next Extended-Support release becomes available, it is advised to move from the Standard-Support to an Extended-Support version that provides the same hardware and software support.

    Cisco IOS XE Software Support

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


    Standard-Support Release - A sustaining support lifetime of 12 months from First Customer Shipment (FCS) with scheduled rebuilds. Examples are Cisco IOS XE Software releases 17.7, 17.8, 17.10 and 17.11.
    Extended-Support Release - A sustaining support lifetime of 36 months from FCS with scheduled rebuilds. Examples are Cisco IOS XE Software releases 17.9, and 17.12.

    Note: Every subsequent third release (for example, Cisco IOS XE Software release 17.6, 17.9, 17.12, 17.15 and so on) is an Extended-Support release.
