2811 Router with 4 port switch module L3 question

We would like to put an IP address on the interfaces of the 4-port switch in the router. We want to be able to configure it like below - int fa0/0/0 ip address It keeps coming up with it is only a layer 2 port. Can we change this port to layer 3?

The 4 port hwic do route you just cannot assign an ip address directly to the port. Create a layer 2 vlan and the corresponding layer 3 SVI , which you assign your ip address to . Then assign the hwic switchport into that vlan . Just about the same as a routed port.
router# vlan database vlan 2 exit conf t interface vlan 2 ip ADDRESS no shut exit int fast2/1 ---> hwic port# switchport acess vlan 2 .
