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 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.
