Details high availability concepts and deployment strategies for Cisco Catalyst Software Defined Wide Area Network, and guides configuration of controller-to-device affinity between Cisco Catalyst controllers and Cisco IOS XE devices to ensure redundancy, failover resiliency, and consistent control plane associations across the network.
Feature history of high availability
Provides feature history information for High availability, including Controller Group Redundancy Management with release identifiers and a description of redundancy behavior that maintains connectivity using SD-WAN controller groups when primary controllers are unavailable.
High availability
Describes high availability in enterprise networks, including goals, hardware redundancy, robust network design, and software mechanisms across control and data planes, with recovery behavior, monitoring intervals, and controller affinity for scalable, geographically distributed connectivity.
Control components redundancy
Outlines the redundancy mechanisms for control components, focusing on ensuring continuous operation and failover in network environments.
Affinity on Cisco IOS XE Catalyst SD-WAN Devices
Describes how a router participates in affinity by configuring the vSmart controllers it is allowed to form control connections with. By default, the system permits two OMP sessions and two control connections per TLOC.
Examples for affinity deployments
Provides examples configuring high availability for different network scenarios.
