I use smoked shanks as well. Meaty, smoky goodness. Brown them well in whatever fat floats your boat. Add onion, carrot, celery, garlic, peppercorns, bay leaf and thyme. Scrape them around in the pan with the shanks until soft and kinda gooey (!), add about 16 cups of cold water. Bring nearly to a boil. Reduce heat and simmer until about 8-10 cups of liquid remain. Periodically skim off the foam and scummy stuff. Strain. Cool-refrigerate-skim fat. Reserve shanks-cool-cover tightly-refrigerate. I use this method for preparing the stock for green/yellow split pea, black-eyed pea and white bean soups. When I'm ready to make the soup, I begin my vegetables of choice in the pan with some butter and evoo. If I'm using dried herbs I add them at this point. If I'm using fresh herbs I add them to the soup during the last 1/2 hour or hour of cooking. Add beans, meat stripped from the shanks and stock. Simmer until done to your liking. A few shots of Franks, Crystal or Tabasco is usually included somewhere in there, too. A pat of butter and black pepper before serving.
