There isn't IP ADDRESS comand in interface configuration mode on router

Hello
I usually use a real router to study but now I have to use posket tracer 6.0.1 ( first time) . When I'am in innterface configuration mode on 2911 router there isn't IP ADDRESS comand . When I check whot commands is possible there isn't also IP command:

Router(config)#interface fastEthernet 0/0/0
Router(config-if)#?
cdp Global CDP configuration subcommands
description Interface specific description
duplex Configure duplex operation.
exit Exit from interface configuration mode
mac-address Manually set interface MAC address
mls mls interface commands
no Negate a command or set its defaults
shutdown Shutdown the selected interface
spanning-tree Spanning Tree Subsystem
speed Configure speed operation.
storm-control storm configuration
switchport Set switching mode characteristics
Router(config-if)#ip address 192.168.1.1 255.255.255.0
^
% Invalid input detected at '^' marker.

Router(config-if)#

Whot heppend ? I really don't understand this .

This is likely just a layer 2 port, not one for routing (a switch port on a router device, basically).

Yes it look like switch port , not one for routing . It is pocket tracer bug ? The router should have ports for routing not only for switching . I know that in L3 switch it is posible to switch between L2 and L3 mode but in router is the same ? Whot have I do to use this port to routing ? It's look like that 2911 router is in fact a normal L2 switch.
1841 and "Generic" Router works ok.

Some routers have ports which are used as only access switch ports and you'd assign them to a VLAN where an SVI will route traffic to other networks.

Thanks docrice , now I nderstand this situation.

+1.

You may have been trying to add ip address to interface on the HWIC-4ESW module, instead of the built-in L3 0/1-0/3 interfaces.

Yes , on bulit in Gigabit Interfaces is OK , this problem is only on HWIC-4ESW module ( I check this now in PT)

Those modules don't provide L3 interfaces. Assign them to a VLAN and set up an SVI for that VLAN. I remember dealing with those on the 2800 series.
