Create management vlan interface on all your switches, let's say 200

SwitchLayer3(config)#interface Vlan200

SwitchLayer3(config-if)#ip address 10.1.200.1 255.255.255.0

SwitchLayer3(config-if)#no shutdown

Switchlayer2(config)#interface Vlan200

Switchlayer2(config-if)#ip address 10.1.200.2 255.255.255.0

Switchlayer2(config-if)#no shutdown

Default gateway of your layer 2 switches

ip default-gateway 10.1.200.1
