If your ports on the switch is trunked, then your end device (like a PC or a server) need to be able to do dot.q also.

However if the port is just an access port, then you can simply plug your end device (PC or server) to it without any need for trunking.

Re: Can i plug an end node into a trunk port?

If the switchport is configured as trunk and the encapsulation is 802.1q, the switchport will send untagged packets by using the native vlan. By default, the native vlan on a 802.1q trunk port is vlan 1. If your Vlan 1 is routable, you should be able to plug an end station into these switchports and have connectivity.

If you post the switch config, we can provide more assistance.
