4. HA link once established synchronizes all system configurations, user databases,
user online status, system resource status, managed AP profile from the Active
AC to the Standby AC.
5. There is a HA link monitoring mechanism by the standby AC when HA links have
been established. This link monitoring module checks the status of the Active
ACs. During an event when an Active AC is not responding, this module will
regard this AC as no longer providing service and take over network service.

devices. Clients associated to locally managed AP will experience the same
scenario (little or no network interruption) as wired clients during service
switchover.
7. Wide Area managed APs (manually or via CAPWAP) over L3 device with tunnels
established will be able to resume service within 5 min max (approximation)
after service switchover with full AP management capacity.
