IEEE 802.3bu-2016 pdf free download – Amendment 8: Physical Layer and Management Parameters for Power over Data Lines (PoDL) of Single Balanced Twisted-Pair Ethernet.
30. Management Change the first paragraph of Clause 30 as follows: This clause provides the Layer Management specification for DTEs, repeaters, MAUs, and Midspans based on the CSMA/CD access method. The clause is produced from the ISO framework additions to Clause 5, Layer Management; Clause 19, Repeater Management; and Clause 20, MAU Management. It incorporates additions to the objects, attributes, and behaviours to support 100 Mb/s, 1000 Mb/s and 10 Gb/s, full duplex operation, MAC Control, Link Aggregation, DTE Power via MDI, Power over Data Lines, subscriber access networks, and the Link Layer Discovery Protocol (LLDP) IEEE 802.3 Organizationally Specific TLVs. The objects, attributes, and behaviours to support Link Aggregation are deprecated by IEEE Std 802.1AX-2008.
30.2 Managed objects
30.2.2 Overview of managed objects
30.2.2.1 Text description of managed objects Change the entry for oPHYEntity as follows: oPHYEntity If oOMPEmulation is implemented, oPHYEntity is contained within oOMPEmu- lation. Otherwise oPHYEntity is contained within oMACEntity. Many instances of oPHYEntity may coexist within one instance of oMACEntity; however, only one PHY may be active for data transfer to and from the MAC at any one time. oPHYEntity is the managed object that contains the MAU, PAF, and PSE, and PoDLPSE managed objects in a DTE. Insert the following new entry for oPoDLPSE into the list, in alphabetical order: oPoDLPSE The managed object of that portion of the containment trees shown in Figure 30–3. The attributes, notifications, and actions defined in 30.15 are con- tained within the PoDLPSE managed object.
30.2.3 Containment Change the first paragraph of 30.2.3 as follows: A containment relationship is a structuring relationship for managed objects in which the existence of a managed object is dependent on the existence of a containing managed object. The contained managed object is said to be the subordinate managed object, and the containing managed object the superior managed object. The containment relationship is used for naming managed objects. The local containment relationships among object classes are depicted in the entity relationship diagrams, Figure 30–3 through Figure 30–6. These figures show the names of the object classes and whether a particular containment relationship is one-to-one, one-to-many or many-to-one. For further requirements on this topic, see IEEE Std 802.1F-1993. PSE and PoDL PSE management are is only valid in a system that provides management at the next higher containment level, that is, either a DTE, or in the case of PSE management only, a repeater or Midspan with management.IEEE 802.3bu pdf download.
