What information is needed by an AP for stateful switchover (SSO) using high availability with a standby WLC?
- the standby WLC
- the group name of the SSO pair
- the IP address of both the primary and standby WLC
- the active primary WLC
Explanation: The AP will have a single CAPWAP tunnel to the active controller. The active unit keeps CAPWAP tunnels, AP states, client states, configurations, and image files all in sync with the hot standby unit. The active controller also synchronizes the state of each associated client that is in the RUN state with the hot standby controller.
