Can a web smart switch be used for Routing? I am using D'Link DES-1228 Web smart switch. Also what is a web smart switch used for?
DLink DES-1228 product info page.
From that info, routing is not a feature of that switch. Look for a Layer 3 switch for routing.
DLink Smart Switch Description: "Smart switches are managed switches with a limited set of features. For a price much lower than a fully managed switch, they provide a web interface to allow configuration of basic settings such as setting VLANS of port speeds."
