Etherchannel and root bridge Sim

The answer has the interfaces grouped into po11, and configured as trunk interfaces

no interface po11
interface range e0/0 - 2
switchport trunk encapsulation dot1q
switchport mode trunk
channel-group 11 mode active

However, don't we have to specifically configure int po11 as a trunk as well?

EX
Interface po11
switchport trunk encapsulation dot1q
switchport mode trunk
Switchport trunk allowed vlans x,x,x

?????

On modern devices, when you configure the command "channel-group <number> mode <active|passive>" on interfaces, the configurations under the interfaces are copied to the Port-channel automatically.
