 		terminates existing links,
 		and stops route-through
 		traffic

     ON		Allows logical links

     RESTRICTED	Allows no new inbound links
 		from other nodes

     SHUT	Allows no new logical links,
 		does not destroy existing
 		links, and goes to the OFF
 		state when all logical links
 		are gone
