Hi All, in a distributed Controller based Environment, is it possible to create more than 16 SSID in the WCS and distribute them to different Controllers, so that SSID 1-4 is propagated to WLC1, 5-8 -> WLC2, ... 17-20 to WLCx? The Customer resides in a Metrowide Area, but shares the same Networking Environment. The WLAN should be centralized managed. Every Customer Locaion has - historical conditioned - his own User DB and intends to use it. Regards, Michael

I don't recall the exact reason, but no, you cannot exceed the 16 vlan limit, but from your example, it sounds like the ssid groups will be bound to unique controllers, thus you can map different ssids to different or shared vlans depending on the back-end infrastructure.

for example (from your question) ssid 1 on WLC1 is bound to vlan 10, subnet 192.168.10.x, and then ssid 2 on WLC1 is bound to vlan 11...

You can then create a ssid on wlc2; ssid 17 bound to the same vlan/subnet as ssid1 on wlc1

Keep in mind that the users will be on the same subnet, therefore ip allocation & security play a larger role.

You can also bind multiple ssids to the same interface on a WLC as well.

The WLCs can then be driven from WCS

Not sure what you mean by their own user DB.

You have a lot of flexibility when it comes to the setup

hope this helps.
