I want to know how to have the ZD3K send an alert within 5 minutes of any 7372 or R500 going disconnected. We have tested the email setup, and get test messages. Just cannot find where to set the delay timer for alerts on disconnect.
The ZoneDirector does not consider an AP to be Disconnected for 20 minutes before sending email alerts. We exchange heartbeats between AP/ZD, and have programmed recovery attempts into the equation, before deciding they are truely "disconnected".
The details, from KBA-1658: What does the "heartbeat lost" message indicate?
ZoneDirector (ZD) and connected Access Points (AP) expect heartbeat (echo) requests or responses in 40 and 30 seconds respectively. If not ZD and AP would consider the heartbeat is lost.
a. After 2 consecutive (80 seconds) heartbeat losses, ZD raises a "heartbeat lost" alert and deletes the AP.
b. After another 20 minutes, if the AP does not discover and join ZD, ZD raises "Lost contact to AP" alert.
c. After a heartbeat lost (30 seconds), AP sends 12 consecutive heartbeat requests every 5 seconds (total 60 seconds). If it still does not hear a response from ZD, AP enters Sole Run state and starts to send discovery request.
d. In Sole Run state, AP sends out discovery request every 5 seconds for 15 minutes. After receiving no responses, AP will reboot and leave a reboot reason viewable in support text stating "cannot discover ZD in 180 attempts".
Hey Michael, sorry to bump this from the grave. This is great info for troubleshooting AP registration. Is there an additional whitepaper/KB that lists all of the possible AP states, and all of these steps along with their required ports? I'm looking for a definitive source of truth for the AP registration process, in detail. I am struggling to find something like this.
