+
+// Dot1AgChassisManagementInfo (class ID #306)
+//	This ME represents the system-level chassis ID or management address for [IEEE-802.1ag] CFM
+//	messages, and potentially for other IEEE 802-based functions. Although [IEEE-802.1AB] allows for
+//	several management addresses (synonyms in different formats or with granularity to the component
+//	level), [IEEE-802.1ag] does not provide for more than one. Nor is it expected that an ONU would
+//	require more than one format. Accordingly, this ME provides for only one.
+//
+//	According to sender ID permission attributes in several dot1ag MEs, transmitted IEEE-802.1ag CFM
+//	messages may include either or both of the chassis ID or management address
+//	fields.[IEEE-802.1ag] requires that CCMs do not exceed 128-bytes, of which 74 are separately
+//	allocated to other purposes; the sender ID TLV, if present, must accommodate this requirement.
+//	The chassis info and management info must fit, with a minimum of 4 additional overhead bytes,
+//	into the remaining 54-bytes. This limit is exploited in defining the maximum size of the ME's
+//	attributes.
+//
+//	Relationships
+//		If an ONU supports [IEEE 802.1ag] functionality, it automatically creates an instance of this
+//		ME.
+//
+//	Attributes
+//		Managed Entity Id
+//			Managed entity ID: This attribute uniquely identifies this ME. There is at most one instance,
+//			whose value is 0. (R) (mandatory) (2-bytes)
+//
+//		Chassis Id Length
+//			Chassis ID length: The length of the chassis ID attribute (not including the chassis ID subtype
+//			attribute), default value 0. (R,-W) (mandatory) (1-byte)
+//
+//		Chassis Id Subtype
+//			(R,-W) (mandatory) (1-byte)
+//
+//		Chassis Id Part 1 Chassis Id Part 2
+//			Chassis ID part 1, Chassis ID part 2: These two attributes may be regarded as an octet string of
+//			up to 50-bytes whose length is given by the chassis ID length attribute and whose value is the
+//			left-justified chassis ID. (R,-W) (mandatory) (25-bytes-*-2 attributes)
+//
+//		Management Address Domain Length
+//			Management address domain length: The length of the management address domain attribute, default
+//			value 0. If this attribute has the value 0, all of the other management address attributes are
+//			undefined. (R,-W) (mandatory) (1-byte)
+//
+//		Management Address Domain 1, Management Address Domain 2
+//			Management address domain 1, Management address domain 2: These two attributes may be regarded
+//			as an octet string of up to 50-bytes whose length is given by the management address domain
+//			length attribute and whose value is the left-justified management address domain. The attribute
+//			is coded as an object identifier (OID) as per [ITUT X.690], referring to a TDomain as defined in
+//			[IETF RFC 2579]. Typical domain values include snmpUDPDomain (from SNMPv2-TM [IETF RFC 3417])
+//			and snmpIeee802Domain (from SNMP-IEEE 802-TM-MIB [IETF RFC 4789]). (R,-W) (mandatory) (25-bytes
+//			* 2 attributes)
+//
+//		Management Address Length
+//			Management address length: The length of the management address attribute, default value 0.
+//			(R,-W) (mandatory) (1-byte)
+//
+//		Management Address 1 Management Address 2
+//			Management address 1, Management address 2: These two attributes may be regarded as an octet
+//			string of up to 50-bytes whose length is given by the management address length attribute and
+//			whose value is the left-justified management address. (R,-W) (mandatory) (25-bytes * 2
+//			attributes)
