+
+// EthernetPerformanceMonitoringHistoryData3 (class ID #296)
+//	This ME collects PM data associated with an Ethernet interface. It includes parameters defined
+//	in the Ethernet statistics group of [IETF RFC 2819] that are not already covered by previously
+//	defined Ethernet monitoring MEs. The received direction is from the CPE towards the network
+//	(upstream).
+//
+//	NOTE 1 - Several of the same counters are available from the Ethernet frame PM history data MEs,
+//	which are associated with MAC bridge ports. MAC bridge port association allows those MEs to be
+//	used for any Ethernet flow, in both upstream and downstream directions, while the Ethernet PM
+//	history data 3 ME can only be used on a physical IEEE 802.3 port.
+//
+//	Instances of this ME are created and deleted by the OLT.
+//
+//	For a complete discussion of generic PM architecture, refer to clause I.4.
+//
+//	NOTE 2 - Implementers are encouraged to consider the Ethernet frame extended PM ME defined in
+//	clause-9.3.32, which collects the same counters in a more generalized way.
+//
+//	Relationships
+//		An instance of this ME is associated with an instance of the PPTP Ethernet UNI.
+//
+//	Attributes
+//		Managed Entity Id
+//			Managed entity ID: This attribute uniquely identifies each instance of this ME. Through an
+//			identical ID, this ME is implicitly linked to an instance of the PPTP Ethernet UNI. (R,
+//			setbycreate) (mandatory) (2-bytes)
+//
+//		Interval End Time
+//			Interval end time: This attribute identifies the most recently finished 15-min interval. (R)
+//			(mandatory) (1-byte)
+//
+//		Threshold Data 1_2 Id
+//			Threshold data 1/2 ID: This attribute points to an instance of the threshold data 1 ME that
+//			contains PM threshold values. Since no threshold value attribute number exceeds 7, a threshold
+//			data 2 ME is optional. (R,-W, setbycreate) (mandatory) (2-bytes)
+//
+//		Drop Events
+//			Drop events:	The total number of events in which packets were dropped due to a lack of
+//			resources. This is not necessarily the number of packets dropped; it is the number of times this
+//			event was detected. (R) (mandatory) (4-bytes)
+//
+//		Octets
+//			Octets:	The total number of octets received from the CPE, including those in bad packets,
+//			excluding framing bytes, but including FCS. (R) (mandatory) (4-bytes)
+//
+//		Packets
+//			Packets:	The total number of packets received, including bad packets, broadcast packets and
+//			multicast packets. (R) (mandatory) (4-bytes)
+//
+//		Broadcast Packets
+//			Broadcast packets: The total number of received good packets directed to the broadcast address.
+//			This does not include multicast packets. (R) (mandatory) (4-bytes)
+//
+//		Multicast Packets
+//			Multicast packets: The total number of received good packets directed to a multicast address.
+//			This does not include broadcast packets. (R) (mandatory) (4-bytes)
+//
+//		Undersize Packets
+//			Undersize packets: The total number of packets received that were less than 64 octets long, but
+//			were otherwise well formed (excluding framing bits, but including FCS). (R) (mandatory)
+//			(4-bytes)
+//
+//		Fragments
+//			Fragments:	The total number of packets received that were less than 64 octets long, excluding
+//			framing bits but including FCS octets, and had either a bad FCS with an integral number of
+//			octets (FCS error) or a bad FCS with a non-integral number of octets (alignment error). It is
+//			entirely normal for this attribute to increment. This is because it counts both runts (which are
+//			normal occurrences due to collisions) and noise hits. (R) (mandatory) (4-bytes)
+//
+//		Jabbers
+//			Jabbers:	The total number of packets received that were longer than 1518 octets, excluding
+//			framing bits but including FCS octets, and had either a bad FCS with an integral number of
+//			octets (FCS error) or a bad FCS with a non-integral number of octets (alignment error). The
+//			range to detect jabber is between 20 ms and 150 ms. (R) (mandatory) (4-bytes)
+//
+//		Packets 64 Octets
+//			Packets 64 octets: The total number of received packets (including bad packets) that were
+//			64-octets long, excluding framing bits but including FCS. (R) (mandatory) (4-bytes)
+//
+//		Packets 65 To 127 Octets
+//			Packets 65 to 127 octets: The total number of received packets (including bad packets) that were
+//			65..127 octets long, excluding framing bits but including FCS. (R) (mandatory) (4-bytes)
+//
+//		Packets 128 To 255 Octets
+//			Packets 128 to 255 octets: The total number of packets (including bad packets) received that
+//			were 128..255 octets long, excluding framing bits but including FCS. (R) (mandatory) (4-bytes)
+//
+//		Packets 256 To 511 Octets
+//			Packets 256 to 511 octets: The total number of packets (including bad packets) received that
+//			were 256..511 octets long, excluding framing bits but including FCS. (R) (mandatory) (4-bytes)
+//
+//		Packets 512 To 1023 Octets
+//			Packets 512 to 1023 octets: The total number of packets (including bad packets) received that
+//			were 512..1023 octets long, excluding framing bits but including FCS. (R) (mandatory) (4-bytes)
+//
+//		Packets 1024 To 1518 Octets
+//			Packets 1024 to 1518 octets: The total number of packets (including bad packets) received that
+//			were 1024..1518 octets long, excluding framing bits but including FCS. (R) (mandatory) (4-bytes)
