MANAGEMENT INTERFACE CISCO WLC 4402

Hello,

I am Brijesh, and facing some problem, furnished hereunder:

Over Switch:
Switch port gi1/0/1 is connected with WLC 4402 Port-1
in Switch port gi1/0/1 I give:
           Switchport trunk encapsulation dot1Q
           Switchport trunk allowed vlan 25,30
           Switchport mode trunk

in Controller 4402:
          By Default it is over Vlan=0=untagged
          If I keep it on Vlan 25 I loose connectivity with controller ...

What should I do ....? I want my Management Interface over a Specific Vlan not default settings.

I have also tried to put the vlan 25 as native vlan (because it is untagged) ... but same result ...
