How frequently is the hello "heartbeat" packet sent from an AP to its controller?

The correct response regarding the frequency of the hello "heartbeat" packet sent from an Access Point (AP) to its controller is every 30 seconds. This heartbeat mechanism is crucial in maintaining the communication between the AP and its controller, allowing for monitoring the status and health of the AP. By sending these packets every 30 seconds, the controller can quickly ascertain if the AP is operational or if it requires any intervention, ensuring a responsive and stable wireless network environment.

The interval of 30 seconds balances the need for frequent updates and network efficiency. Longer intervals might delay the detection of issues, while shorter intervals could lead to unnecessary network traffic and processing overhead. Understanding this timing is key in network management and performance monitoring.
