Hello!
HWIC-1FE is a router interface.In which device are you using it? You cannot configure a L3 port with swichport command.
Use subinterface on that module with "encapsulation dot1q 'vlan_number'" where the vlan_number is configured on the switch (if you connect the router to a switch) and allowed by the trunk config.
Please tell me if you understand or give more details.
Good luck!
