UC520 with Integrated Wireless Controller - Guest WLAN?

Unanswered Question

Hi Netpro Colleagues,

I have a question that I am trying to resolve and I'm not finding any solid information anywhere. I have a customer asking me if there is a possibility to configure a guest WLAN SSID on the UC520 while still providing the normal secure Data and Voice WLAN.

The problem is I can't find any solid information if this is possible or not. Most of the configuration guides that I have found involve using the GUI configuration tool and the screenshots only seem to show the possibility of configuring a voice and a data SSID, however I found a datasheet that seems to indicate that the UC520 can support up to 3 SSIDs.


Is this only possible via CLI? Is this possible at all?

Any help would be greatly appreciated.

Yes it is possible.

For sure, use the CLI only.

The GUI is too buggy and unrelaible for professional results.
