Figure 4 shows the High Availability – AP Stateful Switchover.
In the traditional Controller AP Fail-Over model, a unique IP address for the Primary, Secondary, and Tertiary Controller was configured on each AP. When the AP’s active Controller went down, the AP went to the discovery state, and a whole joining process to a new Controller was required.
The newly introduced High Availability AP Stateful Switchover (AP SSO) model provides a Box-to-Box redundancy with one Controller in Active state and a second Controller in Hot Standby State where it monitors the health of the Active Controller via a Redundant (HA) Port.
The configuration on the Active Controller is synched to the Standby Controller via the Redundant Port. In HA, both controllers share the same set of configuration including the IP Address of the management interface. Furthermore, the AP’s CAPWAP State (for APs in RUN state) are also synched. As a result, APs do not go into Discovery state when the Active Controller fails. This model reduces the Downtime in the case of a Box Failure to sub-second, and to up to three seconds in the case of upstream network connectivity issues (for example, Loss of Gateway).
Note:AIR-CT8510-HA-K9 is available and supports standby operation for up to 6000 APs when connected to the primary 8500 Controller.
