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.

The Cisco Unified Industrial Wireless Software (UIW) 17.x.x releases and following versions are time-based, each with a fixed release date. The schedule specifies 3 individual software releases per year at 4 months intervals approximately. The Cisco Unified Industrial Wireless Software release follows the same timeline as that of Cisco IOS XE release.
The Cisco Unified Industrial Wireless Software naming aligns to IOS-XE Polaris releases’ naming convention.
Cisco Unified Industrial Wireless Software
Each Cisco Unified Industrial Wireless software release is classified as a Standard-Support release.
Standard-Support Release Details
A sustaining support lifetime of 18 months from First Customer Shipment (FCS) is provided. No rebuild releases are typically provided during software release lifetime; optional rebuilds could be provided for urgent fixes.
Software problems found after the final scheduled rebuild release will be fixed in a subsequent major 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 Software release after the End of Vulnerability and Security Support (EoVS) (PSIRT fixes) milestone.
After EoVS, Cisco Technical Assistance Center (TAC) will provide customer support on the affected Cisco Software release, within the guidelines set by existing Cisco’s EoL policies, at the End-of-Software Maintenance milestone.
For HW products running IOS-XE software customers will receive critical vulnerability(PSIRT’s) support through HW LDOS on the final extended maintenance OS release.
End-of-Sale and End-of-Life Guideline Definition
The Cisco Unified Industrial Wireless 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 Unified Industrial Wireless Software version. Table 1 below summarizes the End-of-Sale (EoS) and End-of-Life (EoL) milestones.
