We have had reports from a site where we have deployed H-REAP APs (controller is off-site) that when the controller went off-line (power blip) all the clients were disassociated immediately. We are using WPA/PSK.
Now my understanding is that H-REAP APs should continue to handle clients under these circumstances but the reports suggest that they did not.
Does anyone know under what circumstances this might happen.
And for example can clients continue to roam when the link to the WLC goes down?
To debug further , please see the logs on the AP when this problem happens. You can dump all the logs to a syslog server , so incase the problem happens we can dig out the logs based on time to narrow down the problem.
The power outage only affected the WLC which was on a different site.
Testing in our office has showed that the AP does continue to provide service when the WLC is down, but every time the AP re-associates with a controller - either the original one or a fallback one - the radios are downed and the clients all dis-associated before the new configuration is applied and the client re-associated.
This appears to be by design - does anyone know if this can be prevented?
