AFAIK when the switch is running in Native mode all the ports are in layer 3 mode which means they are routed ports and to configure trunking you have to first convert them into layer 2 mode with "switchport" command under interface config mode.
And once you have converted these routed ports into layer 2 mode then you can configure trunking encapsulation on the interface with command "switchport trunk encapsulation dot1q"
Actually, the dot1q encapsulation is on by default. Strange thing is that it does not allow you to type the command.Also, there is no option for ISL. Where as on other 10/100 cards, there is option for both ISL and dot1q.
