+
+// MacBridgeServiceProfile (class ID #45)
+//	This ME models a MAC bridge in its entirety; any number of ports may be associated with the
+//	bridge through pointers to the MAC bridge service profile ME. Instances of this ME are created
+//	and deleted by the OLT.
+//
+//	Relationships
+//		Bridge ports are modelled by MAC bridge port configuration data MEs, any number of which can
+//		point to a MAC bridge service profile. The real-time status of the bridge is available from an
+//		implicitly linked MAC bridge configuration data ME.
+//
+//	Attributes
+//		Managed Entity Id
+//			Managed entity ID: This attribute uniquely identifies each instance of this ME. The first byte
+//			is the slot ID. In an integrated ONU, this value is 0. The second byte is the bridge group ID.
+//			(R, setbycreate) (mandatory) (2-bytes)
+//
+//		Spanning Tree Ind
+//			Spanning tree ind: The Boolean value true specifies that a spanning tree algorithm is enabled.
+//			The value false disables (rapid) spanning tree. (R,-W, setbycreate) (mandatory) (1-byte)
+//
+//		Learning Ind
+//			Learning ind: The Boolean value true specifies that bridge learning functions are enabled. The
+//			value false disables bridge learning. (R,-W, setbycreate) (mandatory) (1-byte)
+//
+//		Port Bridging Ind
+//			Port bridging ind: The Boolean value true specifies that bridging between UNI ports is enabled.
+//			The value false disables local bridging. (R,-W, setbycreate) (mandatory) (1-byte)
+//
+//		Priority
+//			Priority:	This attribute specifies the bridge priority in the range 0..65535. The value of this
+//			attribute is copied to the bridge priority attribute of the associated MAC bridge configuration
+//			data ME. (R,-W, setbycreate) (mandatory) (2-bytes)
+//
+//		Max Age
+//			Max age:	This attribute specifies the maximum age (in 256ths of a second) of received protocol
+//			information before its entry in the spanning tree listing is discarded. The range is 0x0600 to
+//			0x2800 (6..40-s) in accordance with [IEEE-802.1D]. (R,-W, setbycreate) (mandatory) (2-bytes)
+//
+//		Hello Time
+//			NOTE - [IEEE 802.1D] specifies the compatibility range for hello time to be 1..2-s.
+//
+//		Forward Delay
+//			Forward delay: This attribute specifies the forwarding delay (in 256ths of a second) when the
+//			bridge acts as the root. The range is 0x0400 to 0x1E00 (4..30-s) in accordance with [IEEE
+//			802.1D]. (R,-W, set-by-create) (mandatory) (2-bytes)
+//
+//		Unknown Mac Address Discard
+//			Unknown MAC address discard: The Boolean value true specifies that MAC frames with unknown DAs
+//			be discarded. The value false specifies that such frames be forwarded to all allowed ports.
+//			(R,-W, setbycreate) (mandatory) (1-byte)
+//
+//		Mac Learning Depth
+//			MAC learning depth: This attribute specifies the maximum number of UNI MAC addresses to be
+//			learned by the bridge. The default value 0 specifies that there is no administratively imposed
+//			limit. (R,-W, setbycreate) (optional) (1-byte)
+//
+//		Dynamic Filtering Ageing Time
+//			Dynamic filtering ageing time: This attribute specifies the age of dynamic filtering entries in
+//			the bridge database, after which unrefreshed entries are discarded. In accordance with clause
+//			7.9.2 of [IEEE 802.1D] and clause 8.8.3 of [IEEE 802.1Q], the range is 10..1 000 000-s, with a
+//			resolution of 1-s and a default of 300-s. The value 0 specifies that the ONU uses its internal
+//			default. (R, W, set-by-create) (optional) (4 bytes)
+//
