Dot1Q encapsulation is the only option so there is no need to enter the command.

IF the command "switchport mode trunk" is entered, the port becomes an 802.1Q trunk.
Look at the output to the command "sh interface <PORT> cap" and it should say that the port will only support 802.1Q. ISL is not mentioned because it means it is no longer supported.
