In Packet Tracer 4.11 as well as on real equipment, the switch allows all VLANs (1 to 1005) on a trunk port by default, even if the VLAN does not actually exist on the switch. From the drop-down menu, you can view the VLANs that do exist and block (uncheck) them from the trunk. However, you cannot block VLANs that do not exist. This action does not affect the switch functionality. It is simply a way to display VLANs (or a range of VLANs) that the trunk supports.
