Hello all,
I have a cisco 1811 router with 12.4(6) IOS, I would like to ask can I use this as a layer 2 switch?
When I issue vlan ID command it gives me " Invalid input detected", I need use this device as switch to create different vlan on and the connect the f0 port to a ASA
I appreciate your answer
Regards,

Hi Rouzbeh,
1811 is router, so you can not create vlans the same as you do it on switches, however you can create sub-interfaces with dot.1q tagging
Here are 2 examples:
interface Ethernet0/1.100
encapsulation dot1Q 100
ip address 10.100.5.254 255.255.255.0
!
interface Ethernet0/1.611
encapsulation dot1Q 611
ip address 10.100.7.254 255.255.255.0
