		                 on this MST instance.
		 backup(3) -- this port has the role of backup port on this 
		              MST instance.
		 root(4)-- this port has the role of root port on this MST 
		           instance. 
		 designated(5) -- this port has the role of designated port 
		                  on this MST instance.
		 master(6) -- this port has the role of master port on this 
		              MST instance.
