Here we Map Vlan 10 to VLAN 20 in Gigabit Ethernet port 0/1:

Switch# configure terminal
Switch(config)# interface gigabitethernet 0/1
Switch(config-if)# switchport mode trunk
Switch(config-if)# switchport vlan mapping 10 20
Switch(config-if)# switchport vlan mapping 11 21
Switch(config-if)# switchport vlan mapping 12 22
Switch(config-if)# switchport vlan mapping drop default
Switch(config-if)# end
Switch#

So all incoming Vlan 10 of gi0/1 interface is Converted/Translated to Vlan 20. same way Vlan 11, 12 mapping with 21, 22.

How to verify the configuration:

Switch# show vlan mapping
or
Switch# show interface gigabitethernet 0/1 vlan mapping

State: enabled
