I am using Wireless LAN controller with software version 3.2.78.0. My question is the purpose/function of the "AP Group VLAN" config option under the WLANs section. The on-line help is useless in explaining "what this is" and "when to use" matters. My "guess" is that I can restrict the WLAN (SSID network) that would be serviced for each of the wireless AP? Am I correct? In other words, I could have "test SSID" and "prod SSID", and through this grouping option I can configure a specific AP to service "test SSID" but not "prod SSID", is this correct? And if so, is this the primary/only functions for this configuration?

Thanks in advance.

p.s.

BTW, in my setup I have all wireless network on the same interface and on the same VLAN.
