This release notes document for ExtremeCloud IQ (Classic) version 25.11.2-5 (Patch 2) outlines enhancements, supported platforms, addressed defects, and known limitations for a cloud-managed network management solution. It describes core functionality including device onboarding, monitoring, configuration management, firmware upgrades, and policy enforcement across EXOS/Switch Engine, VOSS/Fabric Engine, and IQ Engine environments, with integration support for controllers, routers, and third-party devices. This release addresses several infrastructure and data pipeline issues identified following the 25.11.0 release. The Elasticsearch cluster was upgraded from version 7.17 to 8.19 with compatibility controls in place, and two resulting regressions were resolved: monitoring queue accumulation caused by Kafka blocking on the schema registry, and the CoPilot Anomaly API returning empty results due to a disabled _id field data setting in Elasticsearch 8.x. Additionally, wired and wireless device usage and capacity client data has been restored by sourcing it directly from the XIQ API, configuration pushes no longer fail for APs running ExtremeCloud IQ Engine versions prior to 10.8.7 when an IP Firewall policy contains more than approximately 25–32 rules, and a deployment defect in the Performance Monitor API Helm chart was corrected to support environment-agnostic configuration of GCP authentication variables. The document details troubleshooting scenarios such as configuration push failures, API inconsistencies, and UI anomalies, along with FAQs and workarounds for onboarding, SSO session handling, and firmware upgrade logging issues. It also defines deployment requirements, supported hardware/software matrices, and interoperability considerations. Intended for intermediate to advanced administrators, it supports secure configuration, operational troubleshooting, and performance validation in large-scale network environments.
