you can't set the same IP's onto all switches but you can have the same vlans and the same subnets

Hi,

Each Device will will have a separate IP Address there you will not be able to get same IP in Both Switches.

Thanks,

configure the vlan ports

Switch(config)#interface range fastEthernet 0/1 - 16
Switch(config-if)#switchport mode access
Switch(config-if)#switchport access vlan 1
Switch(config-if)#no shut
Switch(config)#interface range fastEthernet 0/17 - 32
Switch(config-if)#switchport mode access
Switch(config-if)#switchport access vlan 2
Switch(config-if)#no shut
Switch(config)#interface range fastEthernet 0/33 - 48
Switch(config-if)#switchport mode access
Switch(config-if)#switchport access vlan 3
Switch(config-if)#no shut

configure the trunk port

Switch(config-if)#interface GigabitEthernet0/1
Switch(config-if)#switchport trunk encapsulation dot1q
Switch(config-if)#switchport mode trunk
Switch(config-if)#no shut

on both switches, and you have the situation as drawn in your picture
