Introduction to ISR-AP1100AC-ME-8-8-130-0.zip Software
This firmware package provides critical updates for Cisco’s ISR 1100 and 1100X series routers operating as wireless access points. Released in Q1 2025, version 8.8.130.0 enhances SD-WAN performance while addressing security vulnerabilities identified in previous releases. The update specifically targets hybrid work environments requiring reliable cloud-managed networking with integrated threat protection.
Designed for Catalyst 1100 embedded wireless controllers, the firmware supports dual-band 802.11ac Wave 2 access points with MU-MIMO capabilities. It maintains backward compatibility with IOS XE SD-WAN 17.12.1 architecture, ensuring seamless integration into existing network infrastructures.
Key Features and Improvements
1. Enhanced Security Protocols
- Mitigates CVE-2025-20188 vulnerabilities through improved command execution validation
- Implements TLS 1.3 for AP management plane communications
- Strengthens DNS-layer security through Cisco Umbrella integration
2. SD-WAN Optimization
- Increases IPsec tunnel capacity by 40% (up to 3,000 tunnels on ISR1100X-6G models)
- Improves IMIX throughput to 972 Mbps on 6G platforms
- Adds BFD protocol support for secondary IPv6 subnets
3. Management Enhancements
- Introduces SAML 2.0 group mapping for centralized policy enforcement
- Expands API support for Cisco DNA Center integration
