wireless lan controller

Hello,

In our company we have a cisco wireless lan controller. the managemant interface (untagged 192.168.10.240) is able to ping to all te vlan's. When i add a interface (for example vlan 20 voice 192.168.20.240 255.255.255.0 192.168.20.254) i cant ping that network anymore from my controller while the ip and vlan configurations are good. Can someone help me to solve this problem?

Because you have more than one VLAN, you need to TAG the uplink.  On the switch you need to enable Dot1Q Trunking and allow the required VLAN.
