        DESCRIPTION
			"Enable/Disable loop guard on the switch. 
			 Loop guard allows you to configure the switch to shut down a port if it detects that packets 
			 sent out on that port loop back to the switch. Loop guard is designed to handle loop problems 
			 on the edge of your network. This can occur when a port is connected to a switch that is in a 
			 loop state. Loop state occurs as a result of human error. For example, it happens when two ports 
			 on a switch are connected with the same cable. When a switch in loop state sends out broadcast 
			 messages the messages loop back to the switch and are re-broadcast again and again causing a 
			 broadcast storm."
