What if the ZoneDirector fails?

[steven_smith_60]

Can anyone advise what would happe to our wireless network if the ZoneDirector (3000 series) was to suffer a hardware failure? Would the wireless network cease to function altogether, or would we just lose the ability to make configuration changes?

If the former option is the case, is there anything we can do to the configuration of the APs to safeguard against this eventuality and to eliminate this potential single point of failure?

Yes, this is the "autonomous WLAN" feature being introduced in 9.7. It has some limitations (no DPSK, zero-IT support for example), but does help provide continuous service in the event of a ZD hardware failure.

Keith under 9.7 with an AP that has two WLANs, one normal and one "autonomous" and the ZD goes away (or the AP loses transit to it), will the AP bring down the non autonomous WLAN but keep the autonomous one broadcasting?

I believe in that case the AP will keep both active, but only the autonomous one will allow new connections.

Hello,

I am having reports of some problems related to the unavailability of WLANs when the APs lose contact with the ZD3000. The discovery is made via L3, and the authentication of the WLANs are all local, that is, everything should work, since the ZD300 is managing only the APs, but does not provide any authentication service, such as captive for example.

I know that there is a configuration in the ZD300 for “Auto Recovery”, where we can configure the APs restart cycles in case they lose communication with the ZD. In my scenario, this function is disabled, that is, I understand that the networks must continue to function, as the APs would not enter the restart cycles.

We are working on version 9.12.3.0 build 28, due to the need to support legacies, and we cannot switch to more current versions for now.

Can someone help me? There are some limitations to this scenario.

Thanks.
