Only the first part should increment if it is fully HW switched
Vlan3 (A) <---rpf vlan is correct
GigabitEthernet4/1 (F S)
Gigabit 4/1 is correct and flag 'F' means forwarding is in HW
FastEthernet 4/3 is not listed as it is a switchport and it is part of
vlan 3 which is the incoming vlan. If the switchport was for eg on vlan4,
then you would see vlan 4 in the OIF as a forwarding interface
