Introduction to ISR-AP1100AC-ME-8-10-162-0.zip Software

This software package delivers Cisco IOS XE SD-WAN functionality for ISR1100 and ISR1100X Series routers, optimized for modern branch network deployments. Designed as a feature-enhanced release, it supports advanced security services including Application Awareness, DNS Layer Security, and Cisco Umbrella integration in Viptela operating system configurations.

The firmware version 8.10.162 targets performance improvements in IPsec throughput and SD-WAN overlay tunnel scalability. Though Cisco’s official release notes aren’t publicly accessible for this specific build, historical data from ISR1100 Series documentation confirms its alignment with Cisco’s 2025 SD-WAN architecture roadmap.
