you need to configure both.

but if you configure the port-channel interface it will update the physical
interface configuration.

Here, i even tested it for you

sw1(config)#int fa1/0/1
sw1(config-if)#channel-group 1 mode on
Creating a port-channel interface Port-channel 1

sw1(config-if)#do sh run int fa1/0/1
Building configuration...

Current configuration : 60 bytes
!
interface FastEthernet1/0/1
 channel-group 1 mode on
end

sw1(config-if)#int po1
sw1(config-if)#switchport trunk encapsulation dot1q
sw1(config-if)#switchport mode trunk
sw1(config-if)#do sh run int fa1/0/1
Building configuration...

Current configuration : 121 bytes
!
interface FastEthernet1/0/1
 switchport trunk encapsulation dot1q
 switchport mode trunk
 channel-group 1 mode on
end

sw1(config-if)#do sh run int po1
Building configuration...

Current configuration : 92 bytes
!
interface Port-channel1
 switchport trunk encapsulation dot1q
 switchport mode trunk
end
