Introduction to C9800-SW-iosxe-wlc.17.03.05.SPA.bin

This software maintenance upgrade (SMU) package addresses critical configuration persistence issues in Cisco Catalyst 9800 Series Wireless Controllers operating in High Availability (HA) Stateful Switchover (SSO) environments. Designed for controllers running Cisco IOS XE Dublin 17.9.x releases, this SMU resolves scenarios where configurations might be lost during HA SSO events due to resource constraints in the replication manager (repm) process.

The update applies to all Catalyst 9800 hardware models (C9800-40, C9800-80, C9800-L) and virtual platforms (C9800-CL) operating in INSTALL mode. Cisco officially released this patch in Q1 2025 as part of proactive stability improvements for enterprise wireless networks.

Key Features and Improvements

1. ​​Critical Configuration Stability Fix​​

   • Eliminates configuration loss risks during HA SSO operations by optimizing memory allocation for persistent configuration files.
   • Resolves CSCwj96199: A defect causing incomplete configuration synchronization between active and standby nodes under high CPU utilization (>60%).

2. ​​Preventive Maintenance Enhancements​​

   • Introduces automated checks for persistent storage health before HA SSO activation
   • Adds diagnostic alerts for abnormal repm process behavior

3. ​​Backward Compatibility​​

   • Seamlessly integrates with existing deployments running 17.9.x base images
   • Maintains full compatibility with Smart Licensing Using Policy framework

Compatibility and Requirements

​​Important Restrictions​​:

• Not compatible with BUNDLE mode deployments
• Requires full system reload after installation
• Not supported on controllers with third-party SSL decryption modules
