Introduction to apic-sn-dk9.1.1.2h.iso Software
This software package delivers Cisco Application Policy Infrastructure Controller (APIC) release 1.1.2h for software-defined networking (SDN) environments. Designed for policy automation in Cisco ACI (Application Centric Infrastructure) fabric management, it provides centralized control of distributed switching systems through intent-based policy enforcement.
The build specifically addresses security vulnerabilities CVE-2023-20254 (CVSS 8.6) and CVE-2023-20289 (CVSS 7.8) identified in previous controller versions. Officially released in Q4 2023, it supports Cisco Nexus 9300-EX/FX/GX platform switches and Cloud Network Controller deployments requiring northbound API integration with Kubernetes clusters.
