It's known that SSID supports only one vlan

but is there any way to make a single SSID have multiple Vlans?

"Consider the company have 20 deps. in 20 different VLANs can all of them use the same SSID?" Yes, if there is dynamic vlan assignment on the authentication server. You associate the SSID to the management interface, and then trunk 20 dynamic interfaces to the wlc. The authentication server passes the interface name back to the WLC which maps clients to different vlans on the wired network. http://www.cisco.com/en/US/products/ps6366/products_configuration_example09186a00808c9bd1.shtml http://www.cisco.com/en/US/tech/tk722/tk809/technologies_configuration_example09186a008076317c.shtml Another way to have people on different subnets using the same SSID is to configure access points into different AP Groups which are linked to different subnets, that is doing it on a per AP basis rather than per user basis.
