Cisco 1941 act as a switch ?

[Roselee]

I have installed an 8 port ewhic GE module into the 1941 to act as a switch.

I havecisco 1941 with 5 vlans configured on 0/1 (LAN side)

How do i configure this switch to do intervlan routing route via the 0/1 interface ?

Do i patch a network cable between 0/1 and a GE port on the ewhic switch module or is there backend configuration i need to do to have the module routing traffic internally?
