 //		Designated Bridge Root Cost Port
+//			This attribute contains the designated root, designated cost, designated bridge and designated
+//			port, which are some of the outputs of the read port parameters operation defined in clause
+//			14.8.2.1 of [IEEE-802.1D]:
+//
+//			o	identifier of the designated bridge for the port's segment (8-bytes);
+//
+//			o	bridge identifier of the root transmitted by the designated bridge for the segment (8-bytes);
+//
+//			o	port number of the designated port on the designated bridge considered to be part of this
+//			port's segment (4-bytes);

 //			Upon ME instantiation, the ONU sets this attribute to 0. (R) (mandatory) (24-bytes)

 //		Port State
+//			This attribute provides status information on the port. Valid values include the following.

+//			NOTE - The value linkdown is introduced to denote the port status when the Ethernet link state
+//			is down. This value distinguishes the case where Ethernet is physically down from the case where
+//			Ethernet is administratively locked, the latter being denoted by disabled. Be aware that this
+//			terminology violates the ITUT convention that disabled is an operational state, not
+//			administrative.
+//
 //			The value (R)stp_off is introduced to denote the port status where the (rapid) spanning tree
 //			protocol has been disabled by setting the port spanning tree ind attribute of the MAC bridge
 //			port configuration data to false, and the Ethernet link state is up. This value distinguishes
