Outlines high availability concepts, auto-upgrade strategies, LLDP configuration, reload reason history, prerequisites, fault handling, verification, and deployment—including ACI integration—to ensure resilient wireless controller operations and uninterrupted client connectivity.
High Availability
This topic explains High Availability (HA) and how it reduces wireless network downtime by enabling seamless failover between controllers, ensuring continuous service for APs and clients.
Auto-upgrade feature
Explains the Auto-Upgrade feature that enables the standby controller to upgrade with the software image of the active controller so that both controllers form an HA pair.
Link layer discovery protocol use cases
Describes Link Layer Discovery Protocol (LLDP) use cases in high-availability setups.
Reload reason history
Describes a diagnostic and serviceability feature that records controller reload events and maintains historical data for troubleshooting purposes.
