Which attribute does vManage use to associate and group all controllers within an SD‑WAN deployment?

The organization name is a crucial attribute in Cisco SD-WAN that vManage uses to identify and group all controllers (vManage, vSmart, vBond) and edge devices within a single SD-WAN fabric. This name is configured during the initial setup of each device and must be identical across all components for them to establish secure control plane connections and form a cohesive overlay network. If the organization names do not match, devices will not be able to join the SD-WAN fabric. Incorrect options: vManage system-ip is a unique identifier for the vManage instance but doesn't group all controllers. region ID is used for hierarchical network segmentation and policy application, not for grouping all controllers. secure device ID is a unique hardware-based identifier for individual devices, not a grouping mechanism for the entire fabric.
