Trunk ports are usually carry Vlan traffic to the Connected port.

Short answer for this Yes u Can

it depends on ur Requirement to specify what Vlans should be carried from the Trunk port. If you are allowing all the vlans to trunk port it carries all Vlan 38, Vlan 50 and all the specified vlans on your switch.

#switchport mode trunk

#switchport trunk allowed vlan all

If u specify selected vlans to be carried from the trunk it do carry only those vlans with the tags away from the trunk port. like with the simple example to configure trunk port in carrying vlans from 50 to 80.

switch# switchport mode trunk

#switchport allowed vlan 50-80
