Question : Cisco 800 series router - VLAN

I have little success finding product information I need when I visit Cisco's site.  

I would like to know if the 4 ethernet ports in a series 800 router are a managed switch, specififcally if the IOS offers options for vlan implementation on those ports.

Thanks for any advice.
