For the VLAN interface or the SVI to come up, you should have atleast one port connected to that VLAN or you should have a trunk configured in that switch

HTH, rate if it does

You mean to say you had disabled STP on the switch?

You need at least one active interface on that vlan , whether it is a user pc or just having the vlan included in a trunk in order for the layer 3 SVI come up , this due to the autostate function of the switch . Make sure the layer 2 vlan is created with the show vlan command.
