The physical link is a fiber optical link. The OLT and ONUs are connected through passive optical splitters. Downlink denotes the transmission from the OLT to the ONUs. Uplink denotes the transmission from the ONUs to the OLT. Uplink and downlink are multiplexed using separated wavelengths on the same fiber. The downlink is a broadcast medium where the OLT transmits the data to all ONUs. The uplink is a shared transmission medium for all of the ONUs. The uplink access is based on time division multiplexing (TDM) and the management of the TDM media access is defined by the Multi-
物理链路是光纤链路。OLT和ONU通过无源分光器连接。下行链路表示从OLT到ONU的传输。上行链路表示从ONU到OLT的传输。上行链路和下行链路在同一光纤上使用分离的波长进行多路复用。下行链路是一种广播媒体，其中OLT向所有onu发送数据。上行链路是所有onu的共享传输介质。上行链路接入基于时分复用（TDM），TDM媒体接入的管理由多用户定义-
Point Control Protocol (MPCP). The MPCP is a control protocol based on an inband packet messaging. The OLT sends control messages (GATE messages) allowing ONUs to transmit, defining when the transmission occurs and what is its duration. These messages define the transmission order and the amount of BW for each ONU. A scheduling algorithm at the OLT, which is not defined in the [802.3ah], is responsible for allocating the BW and controlling the delay of each ONU according to its SLA.
点控制协议（MPCP）。MPCP是基于带内分组消息传递的控制协议。OLT发送允许ONU传输的控制消息（门消息），定义传输发生的时间及其持续时间。这些消息定义每个ONU的传输顺序和BW量。OLT上的调度算法（未在[802.3ah]中定义）负责分配BW并根据其SLA控制每个ONU的延迟。
PMD specifications select the same optical wavelength plan as the [ITU-T.G.983]. The transceivers are derivatives of existing Ethernet optical transceivers, with dual wavelength on a single fiber, and extended burst capabilities for the uplink. The uplink burst capability is the burst transmission functionality for the ONUs and burst reception functionality for the OLT. The [802.3ah] selected very relaxed burst parameters to reduce the device cost of EPON products.
PMD规范选择与[ITU-T.G.983]相同的光波长计划。收发器是现有以太网光收发器的衍生产品，在一根光纤上具有双波长，并扩展了上行链路的突发能力。上行链路突发能力是onu的突发传输功能和OLT的突发接收功能。[802.3ah]选择了非常宽松的突发参数，以降低EPON产品的设备成本。
The downstream is a broadcast link, which means that the OLT transmission is shared for all ONUs. The sharing of the transmission of the OLT has some negative privacy aspects and should be limited to broadcast traffic in nature only. The traffic dedicated to each ONU should not be shared. The solution provided by [802.3ah] is to partition the EPON link, in a virtual manner, between the ONUs. Each ONU has a dedicated virtual link to the OLT. The [802.3ah] also defines an additional link for broadcast transmission. The medium becomes an aggregation of point-to-point tunnels. The OLT cannot preserve its EPON interface as a single interface connected to N devices (following the properties of the physical interface). The EPON interface of the OLT is partitioned into separate virtual interfaces; an interface for each virtual link. Hence, the OLT behaves like a device with N virtual ports (and an additional port for the broadcast transmission). The additional single-copy-broadcast channel (tagged as all one LLID) is added to allow the broadcast transmission within a single copy to all ONUs, preserving the inherent advantage of BW efficiency of the PON shared media. The ONUs filter the downlink traffic that is not intended for their reception, according to the virtual link marking. An LLID tag is attached at the preamble of the Ethernet packet denoting the virtual link. The LLID marks the destination port in the downstream and source port in the upstream.
下游是广播链路，这意味着OLT传输为所有ONU共享。OLT传输的共享具有一些负面隐私方面，并且应仅限于广播通信量。不应共享专用于每个ONU的流量。[802.3ah]提供的解决方案是在ONU之间以虚拟方式划分EPON链路。每个ONU都有一个到OLT的专用虚拟链路。[802.3ah]还定义了用于广播传输的附加链路。介质成为点到点隧道的集合。OLT不能将其EPON接口保留为连接到EPON设备的单个接口（遵循物理接口的属性）。OLT的EPON接口被划分为单独的虚拟接口；每个虚拟链接的接口。因此，OLT的行为类似于具有N个虚拟端口（以及用于广播传输的附加端口）的设备。添加附加的单拷贝广播信道（标记为all-one LLID）以允许在单个拷贝内向所有ONU进行广播传输，从而保持PON共享媒体的BW效率的固有优势。ONU根据虚拟链路标记过滤不打算接收的下行链路通信量。LLID标签附在表示虚拟链路的以太网分组的前导处。LLID在下游标记目标端口，在上游标记源端口。
The virtual links concept is also used to avoid a violation of the [802.1d] bridging rules for peer-to-peer traffic in the PON. Peer-to-peer traffic is traffic between ONUs in the same PON. The OLT cannot preserve the EPON interface as a single interface, connected to N devices, and allow traffic between these devices without violating the bridging rules. The source address and destination address of the peer-to-peer traffic are behind the same port and therefore the traffic should be discarded. The separation of the ONUs into virtual links solves this issue. The OLT has N virtual ports for the single physical EPON port. A bridge sees a single MAC Client for every link pair.
虚拟链路概念还用于避免违反PON中对等通信的[802.1d]桥接规则。对等通信量是同一PON中ONU之间的通信量。OLT不能将EPON接口保留为单个接口，连接到N个设备，并且在不违反桥接规则的情况下允许这些设备之间的通信。对等通信的源地址和目标地址位于同一端口后面，因此应丢弃该通信。将ONU分离为虚拟链路解决了这个问题。OLT有N个虚拟端口用于单个物理EPON端口。网桥可以看到每个链路对都有一个MAC客户端。
The private paths concept solves the networking problems and provides subscriber isolation.
专用路径概念解决了网络问题，并提供了用户隔离。
As the tunneling is only a virtual tunneling, there is a single physical interface and a single physical layer for the device so that some attributes are shared. For example, the interface has a single local MAC address.
由于隧道只是一个虚拟隧道，因此设备只有一个物理接口和一个物理层，因此一些属性是共享的。例如，接口有一个本地MAC地址。
The virtual tunneling for an OLT with 3 ONUs is illustrated in the following diagram.
具有3个ONU的OLT的虚拟隧道如下图所示。

The EPON standard defines a media access control of an optical Access network. The Access network has some substantial differences from the legacy LAN for which the Ethernet was designed. The differences lie mainly in the provisioning of the network. An Access network is an administrated environment, with an operator providing the service and subscribers consuming it. The operator is controlling the network and managing its traffic. For instance, BW is controlled and subscribers are billed for services. The MPCP protocol divides the Ethernet interfaces into two unequal types of network units. The first interface is an OLT interface, which is a server unit, controlling the network. The second interface is an ONU interface, which is a client unit, participating in the network.
EPON标准定义了光接入网络的媒体接入控制。接入网络与设计以太网的传统LAN有一些实质性的区别。区别主要在于网络的配置。接入网是一个管理环境，由运营商提供服务，用户使用服务。运营商控制网络并管理其流量。例如，BW是受控的，订阅者为服务付费。MPCP协议将以太网接口分为两种不同类型的网络单元。第一个接口是OLT接口，它是控制网络的服务器单元。第二个接口是ONU接口，它是参与网络的客户端单元。
The OLT, which is the server unit, manages the network. The MPCP controls the TDM transmission of the uplink. The MPCP is implemented at the MAC control layer and the MPCP messages are MAC control messages using the 0x8808 Ethertype. These messages are not forwarded out of the MAC.
OLT是服务器单元，负责管理网络。MPCP控制上行链路的TDM传输。MPCP在MAC控制层实现，MPCP消息是使用0x8808以太网类型的MAC控制消息。这些消息不会从MAC转发出去。
A concept of time must exist in the protocol in order to schedule the uplink transmission. A timestamp, which is set by the OLT and synchronized between the network units, is passed through the MPCP messages. The timestamp is also used to measure the RTT of each ONU. RTT is compensated by the OLT in the generation of the grants for the uplink transmission. The difference of incoming timestamp to local time allows the OLT to calculate the RTT. RTT compensation is needed as the RTT in an Access network can have a significant value. The standard allows the network to reach a 20 km distance, which is equivalent to a 200 usec RTT (25 Kbytes of data).
为了调度上行链路传输，协议中必须存在时间概念。由OLT设置并在网络单元之间同步的时间戳通过MPCP消息传递。时间戳还用于测量每个ONU的RTT。RTT由OLT在为上行链路传输生成授权时进行补偿。传入时间戳与本地时间的差值允许OLT计算RTT。需要RTT补偿，因为接入网络中的RTT可能具有重要价值。该标准允许网络达到20公里的距离，相当于200 usec RTT（25千字节的数据）。
The TDM control is done using GATE messages. These messages define, for each ONU, the time for transmission and the length of transmission. The RTT is reduced from the transmission time in the GATE message to shift the transmission time of the ONU in the opposite direction.
TDM控制使用门消息完成。这些消息为每个ONU定义传输时间和传输长度。RTT从门消息中的传输时间减少，以使ONU的传输时间向相反方向移动。
A scheduling algorithm at the OLT, which is not defined in the [802.3ah], is responsible for dividing the BW and controlling the transmission delay of each ONU according to its SLA. The MPCP defines a closed loop operation in order for this algorithm to be efficient. The MPCP allows the ONUs to report on the amount of BW they require for transmission using a special REPORT message. This allows allocating BW to an ONU only when requested, relying on the statistical burst property of the traffic, and allowing different peak BW for different ONUs at different times; hence, allowing oversubscription of the BW. The REPORT message reports the amount of data waiting in the ONU queues.
OLT处的调度算法（未在[802.3ah]中定义）负责划分BW并根据其SLA控制每个ONU的传输延迟。MPCP定义了一个闭环操作，以使该算法有效。MPCP允许ONU使用特殊报告消息报告传输所需的BW量。这允许仅在请求时根据业务的统计突发特性将BW分配给ONU，并且允许不同ONU在不同时间的不同峰值BW；因此，允许BW的超额认购。报告消息报告ONU队列中等待的数据量。
In addition, the MPCP defines a protocol of auto-discovery and registration of ONUs.
此外，MPCP定义了ONU的自动发现和注册协议。
The registration process is defined in the diagram below:

A new ONU requests to register (sends a REG_REQUEST message) in a special discovery grant, allocated for that by the OLT. During that time, more than one ONU might try to register. A collision in transmission might occur, as the RTT of the new ONUs is not yet known. A random backoff mechanism of the transmission is used to schedule the following registration requests to avoid these collisions. When the OLT receives a REG_REQUEST message of an ONU and approves this ONU, then it sends a REGISTER message to this ONU defining its LLID. From that point, the ONU transmission is scheduled by its LLID, knowing the RTT, and no collision can occur. The ONU replies with a REGISTER_ACK message and the registration process of the MPCP ends. Higher layer protocols may be needed to authenticate the ONU and allow it to participate in the network.
新ONU请求在由OLT分配的特殊发现授权中注册（发送REG_请求消息）。在此期间，可能会有多个ONU尝试注册。传输中可能会发生冲突，因为新ONU的RTT还未知。传输的随机退避机制用于调度以下注册请求以避免这些冲突。当OLT接收到ONU的REG_请求消息并批准该ONU时，它会向该ONU发送一条注册消息，定义其LLID。从那时起，ONU传输由其LLID调度，知道RTT，并且不会发生冲突。ONU回复REGISTER_ACK消息，MPCP的注册过程结束。可能需要更高层的协议来认证ONU并允许其参与网络。
The FEC is defined to enhance the link budget of the PON. As each splitter attenuates the optical signal, the number of the splits and the distance are limited by the link budget. Hence an FEC that
定义FEC是为了增强PON的链路预算。当每个分离器衰减光信号时，分离器的数量和距离受到链路预算的限制。因此，联邦选举委员会
improves the link budget has a benefit. The FEC code used is the RS(239,255,8), similar to the FEC code in [ITU-T.G.975], improving the BER from 1E-4 to 1E-12.
改善链接预算有一个好处。使用的FEC代码是RS（239255,8），类似于[ITU-T.G.975]中的FEC代码，将误码率从1E-4提高到1E-12。
The FEC parity encapsulation is based on the framing of the Ethernet packet. The Ethernet packets are spaced by MAC rate adaptation, and the parity bytes are inserted after the packet in the provided space.
FEC奇偶校验封装基于以太网数据包的帧。以太网分组通过MAC速率自适应来隔开，并且奇偶校验字节被插入到所提供空间中的分组之后。
As the start and end of packet codewords also define the FEC boundaries, and they are outside the FEC protection, they are replaced by a series of symbols to reduce their vulnerability to errors.
由于数据包的起始和结束码字也定义了FEC边界，并且它们不在FEC保护范围内，因此它们被一系列符号所取代，以减少它们对错误的脆弱性。
The following diagram presents an FEC-protected frame:

The FEC is added in a separate layer between the PCS and PMA layers of the [802.3].
FEC添加在[802.3]的PCS和PMA层之间的单独层中。
The FEC layer introduces a fixed delay in receive path and transmit path.
FEC层在接收路径和发送路径中引入固定延迟。
The FEC layer is optional.
FEC层是可选的。
Each one of the EPON layers is accompanied by a management interface that is controlled through clause 30 of the [802.3ah]. As the [802.3ah] specification may be used for different applications, and some of the clauses may be used separately, the IEEE management clause allocates for each one of them a separate package. The MIB document follows this partition.
每个EPON层都附带一个管理接口，该接口由[802.3ah]第30条控制。由于[802.3ah]规范可用于不同的应用，并且其中一些条款可单独使用，因此IEEE管理条款为每一个条款分配一个单独的包。MIB文档遵循此分区。
The following diagram presents the relation of the MIB groups to the [802.3ah] layers:

The association is straightforward for the ONU interface. There is one logical and one physical interface, and a single copy exists for each layer that can be remotely queried by the OLT.
对于ONU接口，关联是简单的。有一个逻辑接口和一个物理接口，OLT可以远程查询每个层的一个副本。
At the OLT there is a single physical interface and N virtual interfaces for the virtual links of the ONUs (and another virtual interface for the broadcast virtual link). As can be seen from the layering diagram above, the MAC layer is virtually duplicated. Therefore, in this document it was selected that the management of a virtual interface is like a physical interface, an interface index is allocated for each one of the virtual links, and an additional interface index is allocated for the OLT.
在OLT处，onu的虚拟链路有一个物理接口和N个虚拟接口（广播虚拟链路有另一个虚拟接口）。从上面的分层图可以看出，MAC层实际上是重复的。因此，在本文件中，选择了虚拟接口的管理类似于物理接口，为每个虚拟链路分配接口索引，并为OLT分配额外的接口索引。
To illustrate the interface modeling consider two devices; the first device has two physical interfaces, is typically located at a consumer's site, and is called an "ONU modem".
为了说明接口建模考虑两个设备；第一个设备有两个物理接口，通常位于用户站点，称为“ONU调制解调器”。
An "ONU modem" is shown in the figure below:
“ONU调制解调器”如下图所示：
--------
ONU interface | ONU | 10 megabit interface
--------------| modem |--------------------
---------
--------
ONU interface | ONU | 10 megabit interface
--------------| modem |--------------------
---------
This device would have 3 entries in the IF table, and one IF stack entry; for example:
该设备在IF表中有3个条目，一个IF堆栈条目；例如：
ifIndex=1 - interface for 10 megabit interface
ifIndex=1-10兆位接口的接口
ifIndex=2 - interface for the optical interface
ifIndex=2-光学接口的接口
ifIndex=200 - interface for the ONU interface
ifIndex=200-ONU接口的接口
And then in the IF stack table:
然后在IF堆栈表中：
ifStackHigherLayer=200, ifStackLowerLayer=2 - map between the physical and the ONU
ifStackHigherLayer=200，ifStackLowerLayer=2-物理和ONU之间的映射
The second device has three physical interfaces, is typically located at the provider's site, and may be called a "headend".
第二个设备具有三个物理接口，通常位于提供商的站点，并且可以称为“头端”。
A "headend" is shown in the figure below:
“前端”如下图所示：
---------
1st OLT interface | Head | gigE interface
------------------| end |--------------------
| |
------------------| |
2nd OLT interface | |
---------
---------
1st OLT interface | Head | gigE interface
------------------| end |--------------------
| |
------------------| |
2nd OLT interface | |
---------
This device would have 5 entries (when there are no attached ONUs) in the IF table, for example:
此设备在IF表中有5个条目（当没有附加ONU时），例如：
ifIndex=1 - interface for gigE interface
ifIndex=1-gigE接口的接口
ifIndex=2 - interface for 1st optical interface
ifIndex=2-第一个光学接口的接口
ifIndex=3 - interface for 2nd optical interface
ifIndex=3-第二个光学接口的接口
ifIndex=265535 - interface for the 1st OLT broadcast interface
ifIndex=265535-第一个OLT广播接口的接口
ifIndex=365535 - interface for the 2nd OLT broadcast interface
ifIndex=365535-第二个OLT广播接口的接口
And then in the IF stack table:
然后在IF堆栈表中：
ifStackHigherLayer=265535, ifStackLowerLayer=2 - map between the 1st physical and its broadcast interface
ifStackHigherLayer=265535，ifStackLowerLayer=2-第一个物理接口与其广播接口之间的映射
ifStackHigherLayer=365535, ifStackLowerLayer=3 - map between the 2nd physical and its broadcast interface
ifStackHigherLayer=365535，ifStackLowerLayer=3-第二个物理接口与其广播接口之间的映射
If two ONUs connected to the first OLT interface, then for example, the following entries would be added to the IF table:
例如，如果两个ONU连接到第一个OLT接口，则以下条目将添加到If表中：
ifIndex=200001 - interface for the 1st ONU of 1st OLT
ifIndex=200001-用于第一个OLT的第一个ONU的接口
ifIndex=200002 - interface for the 2nd ONU of 1st OLT
ifIndex=200002-用于第一个OLT的第二个ONU的接口
And in the IF stack table:
在IF堆栈表中：
ifStackHigherLayer=200001, ifStackLowerLayer=2 - map between the 1st physical and 1st ONU
ifStackHigherLayer=200001，ifStackLowerLayer=2-第一个物理和第一个ONU之间的映射
ifStackHigherLayer=200002, ifStackLowerLayer=2 - map between the 1st physical and 2nd ONU
ifStackHigherLayer=200002，ifStackLowerLayer=2-第一个物理和第二个ONU之间的映射
For each physical interface, there would be an entry (ifIndex) in the tables of the interface MIB module [RFC2863], MAU MIB module [RFC4836], and Etherlike MIB module [RFC3635]. Additionally, there would be entries (ifIndexes) for the virtual interfaces of the OLT interface. The justification for the additional allocation of indexes is that the virtual interfaces are quite well distinguished, as they connect different physical ONUs from the OLT side. For instance, there is a meaning for separate bad frames counter or bad octets counter for each virtual link, as the ONUs can be differently distanced. This is quite similar to a case of separate physical interfaces.
对于每个物理接口，接口MIB模块[RFC2863]、MAU MIB模块[RFC4836]和以太MIB模块[RFC3635]的表中都会有一个条目（ifIndex）。此外，OLT接口的虚拟接口将有条目（IFIndex）。额外分配索引的理由是，虚拟接口可以很好地区分，因为它们从OLT端连接不同的物理ONU。例如，对于每个虚拟链路，有单独的坏帧计数器或坏八位字节计数器的含义，因为ONU的距离可以不同。这与单独物理接口的情况非常相似。
The same partition concept exists for the MIB module of this document. Each row in the tables are indexed according to the ifIndex; specifically, there is a row for each virtual link. There are some control objects that are shared and are the same for the virtual interfaces (and they should have the same value for each ifIndex), but most of the objects have different values for N+1 logical interfaces at the OLT. This is done for each MIB group. It is a bit different from the [802.3ah] layering diagram, which presents the P2MP layer as a single layer, while duplicating the MAC and MAC client layers (please see the diagram above). However, from a management perspective, it is more convenient and neat to partition the management of the layers for the virtual links, as the atomic managed entity is the virtual link. It is also convenient to use the interface index of the virtual link for that purpose, as it is already used to index the rows of the virtual links at the Interface, MAU, and etherLike interfaces MIBs.
本文档的MIB模块也存在相同的分区概念。表中的每一行都根据ifIndex编制索引；具体来说，每一行都有一个虚拟链接。有些控制对象是共享的，并且对于虚拟接口是相同的（对于每个ifIndex，它们应该具有相同的值），但是对于OLT上的N+1逻辑接口，大多数对象具有不同的值。这是为每个MIB组完成的。它与[802.3ah]分层图略有不同，后者将P2MP层表示为一个单层，同时复制MAC和MAC客户端层（请参见上图）。然而，从管理的角度来看，划分虚拟链接的层的管理更方便、更整洁，因为原子管理实体就是虚拟链接。使用虚拟链接的接口索引也很方便，因为它已经用于索引接口、MAU和类以太接口MIB处的虚拟链接行。
This document defines the DOT3 EPON MIB module. The DOT3 EPON MIB module defines the objects used for management of the [802.3ah] Point-to-Multipoint (P2MP) interfaces. These MIB objects are included in four groups.

dot3ExtPkgOptIfTable定义了每个逻辑链路的对象，用于EPON兼容接口的光学接口的控制和状态指示。
As described in the architecture section, each row in the tables is indexed according to the ifIndex; specifically, there is a row for each virtual link. There are a few control objects that are shared and have the same value for the virtual interfaces (and they should have the same value for each ifIndex), but most of the objects have different values for N+1 logical interfaces at the OLT. This is done for each MIB group. It is a bit different from the [802.3ah] layering diagram, which presents the P2MP layer as a single layer while duplicating the MAC and MAC client layers. However, from a management perspective, it is more convenient and neat to partition the management of the layers for the virtual links, as the atomic managed entity is the virtual link. It is also convenient to use the interface index of the virtual link for that purpose, as it is already used to index the rows of the virtual links at the Interface, MAU, and etherLike interfaces MIBs.
如架构部分所述，表中的每一行都根据ifIndex进行索引；具体来说，每一行都有一个虚拟链接。有几个控制对象是共享的，并且对于虚拟接口具有相同的值（对于每个ifIndex，它们应该具有相同的值），但是大多数对象对于OLT的N+1逻辑接口具有不同的值。这是为每个MIB组完成的。它与[802.3ah]分层图有点不同，后者将P2MP层表示为一个单层，同时复制MAC和MAC客户端层。然而，从管理的角度来看，划分虚拟链接的层的管理更方便、更整洁，因为原子管理实体就是虚拟链接。使用虚拟链接的接口索引也很方便，因为它已经用于索引接口、MAU和类以太接口MIB处的虚拟链接行。

For example, provided below are the values of the MPCP control table of the OLT after initialization, before the ONUs register.
例如，下面提供的是初始化后ONU寄存器之前OLT的MPCP控制表的值。
The table below presents the MPCP control table of the OLT after initialization. A single row exists in this table associated with the virtual broadcast link.

Table 4
表4
BRCT_MAC_Address is the MAC address of the broadcast EPON interface, which is the OLT MAC address.
BRCT_MAC_Address是广播EPON接口的MAC地址，即OLT MAC地址。
EPON interface is a kind of Ether-like interface. This MIB module extends the objects of the Interface MIB and the Ether-like Interfaces MIB for an EPON type interface.
EPON接口是一种醚类接口。此MIB模块扩展接口MIB的对象，以及EPON类型接口的以太类接口MIB。
Implementing this module therefore MUST require implementation of the Interfaces MIB module [RFC2863] and the Ethernet-like Interfaces MIB module [RFC3635].
因此，实现该模块必须实现接口MIB模块[RFC2863]和类以太网接口MIB模块[RFC3635]。
Thus, each managed EPON interface would have a corresponding entry in the mandatory tables of the Ether-like MIB module found in [RFC3635], and likewise in the tables of the Interface MIB module found in [RFC2863]. Also each managed virtual EPON interface would have a corresponding entry in the mandatory tables of the Ether-like MIB module found in [RFC3635], and likewise in the tables of the Interface MIB module found in [RFC2863] with a dedicated ifIndex for this interface.
因此，每个受管EPON接口将在[RFC3635]中发现的乙醚类MIB模块的强制表中以及[RFC2863]中发现的接口MIB模块的表中具有相应的条目。此外，每个受管虚拟EPON接口在[RFC3635]中发现的以太类MIB模块的强制表中，以及在[RFC2863]中发现的接口MIB模块的表中，都会有一个相应的条目，并具有该接口的专用ifIndex。
In this document, there is no replication of the objects from these MIBs. Therefore, for instance, the document is defining dot3MpcpRemoteMACAddress only while assuming that the local MAC address object is already defined in [RFC3635].
在本文档中，没有从这些MIB复制对象。因此，例如，文档仅在假设本地MAC地址对象已在[RFC3635]中定义的情况下定义DOT3MPCPPREMOTEMACADDRESS。
The interface MIB module [RFC2863] defines the interface index (ifIndex). Interface Index, as specified in [RFC2863], is used in this MIB Module as an index to the EPON MIB tables. The ifIndex is used to denote the physical interface and the virtual link interfaces at the OLT. The OLT interface and the virtual link interfaces are stacked using the ifStack table defined in [RFC2863], and the ifInvStack defined in [RFC2864]. The OLT interface is the lower layer of all other interfaces associated with the virtual links.
接口MIB模块[RFC2863]定义接口索引（ifIndex）。[RFC2863]中规定的接口索引在此MIB模块中用作EPON MIB表的索引。ifIndex用于表示OLT的物理接口和虚拟链路接口。OLT接口和虚拟链路接口使用[RFC2863]中定义的ifStack表和[RFC2864]中定义的ifInvStack进行堆叠。OLT接口是与虚拟链路相关联的所有其他接口的较低层。
This document defines the specific EPON objects of an ONU interface and an OLT interface. Information in the tables is per LLID. The rows in the EPON MIB tables referring to the LLIDs are denoted with the corresponding ifIndexes of the virtual link interfaces.
本文档定义了ONU接口和OLT接口的特定EPON对象。表中的信息为每个LLID。EPON MIB表中引用LLID的行用虚拟链路接口的相应IFIndex表示。
Please note that each virtual interface does not have a different physical MAC address at the OLT, as the physical interface is the same. It is specified in the [802.3ah], Section 64.1.2. The corresponding object of the Ether-like interface MIB is duplicated for all the virtual interfaces.
请注意，每个虚拟接口在OLT上没有不同的物理MAC地址，因为物理接口是相同的。[802.3ah]第64.1.2节对其进行了规定。对于所有虚拟接口，类以太接口MIB的对应对象都是重复的。
For example, the values of the Interface MIB objects are presented in the following tables, for an OLT with 3 registered ONUs:
例如，对于具有3个注册ONU的OLT，接口MIB对象的值显示在下表中：

The rows for the ONU interface, the OLT interface, and the OLT broadcast interface are created in initialization.
ONU接口、OLT接口和OLT广播接口的行在初始化时创建。
The creation of a row for a virtual link is done when the virtual link is established (ONU registers), and deletion is done when the virtual link is deleted (ONU deregisters).
为虚拟链路创建行是在建立虚拟链路（ONU注册）时完成的，删除是在删除虚拟链路（ONU注销）时完成的。
The EPON MIB module also extends the Interface MIB module with a set of counters, which are specific for the EPON interface. The EPON MIB module implements the same handling of the counters when the operation of the interface starts or stops. The interface MIB document describes the possible behavior of counters when an interface is re-initialized using the ifCounterDiscontinuityTime indicator, indicating the discontinuity of the counters. Please see [RFC2863], Section 3.1.5, page 11 for more information. The counters of the EPON MIB should be handled in a similar manner.
EPON MIB模块还使用一组特定于EPON接口的计数器扩展接口MIB模块。EPON MIB模块在接口操作开始或停止时对计数器执行相同的处理。接口MIB文档描述了当使用IFCounterInterruptionTime指示器重新初始化接口时计数器的可能行为，指示计数器的不连续性。更多信息请参见[RFC2863]，第11页第3.1.5节。EPON MIB的计数器应以类似方式处理。
The MAU types of the EPON Interface are defined in the amended MAU MIB document. This document assumes the implementation of the MAU MIB for this purpose and does not repeat the EPON MAU types. Therefore, implementing this module MUST require implementation of the MAU-MIB module [RFC4836].
EPON接口的MAU类型在修订的MAU MIB文档中定义。本文档假定为此目的实现MAU MIB，并且不重复EPON MAU类型。因此，实现该模块必须实现MAU-MIB模块[RFC4836]。
The handling of the ifMAU tables for the EPON case is similar to the handling described in the former section for the Interface and Ether-like interface MIBs. A single row exists for the ONU in the ifMauTable. A row for each virtual link (N+1 rows) exists at the OLT, with a separate value of ifMauIfIndex for each virtual link.
EPON情况下ifMAU表的处理类似于前一节中描述的接口和以太类接口MIB的处理。IFMAU表中存在ONU的单行。OLT上存在每个虚拟链路的一行（N+1行），每个虚拟链路有一个单独的ifMauIfIndex值。
As specified above, the rows for the ONU interface, the OLT interface, and the OLT broadcast interface are created in initialization.
如上所述，ONU接口、OLT接口和OLT广播接口的行在初始化时创建。
The creation of a row for a virtual link is done when the virtual link is established (ONU registers), and deletion is done when the virtual link is deleted (ONU deregisters).
为虚拟链路创建行是在建立虚拟链路（ONU注册）时完成的，删除是在删除虚拟链路（ONU注销）时完成的。
The EPON interfaces are aimed to the optical access networks and most probably will be accompanied with the implementation of the OAM section of the [802.3ah]. Therefore, the EFM OAM MIB module [RFC4878] MAY be implemented when this MIB module is implemented defining managed objects for the OAM layer that are complementary to the EFM EPON MIB module. As the OAM is defined for a point-to-point link it is implemented in this case using the virtual links that are
EPON接口的目标是光接入网络，并且很可能伴随着[802.3ah]的OAM部分的实施。因此，当实现该MIB模块时，可以实现EFM OAM MIB模块[RFC4878]，该MIB模块为OAM层定义补充EFM EPON MIB模块的托管对象。由于OAM是为点到点链路定义的，因此在本例中使用以下虚拟链路来实现：
defined for the P2MP network, so that an instance is held for each Logical Link Identifier (LLID) of the EPON. The corresponding ifIndex of the virtual link is used as the ifIndex of the tables of the OAM MIB module for this purpose.
为P2MP网络定义，以便为EPON的每个逻辑链路标识符（LLID）保留一个实例。为此，虚拟链路的相应ifIndex用作OAM MIB模块表的ifIndex。
It is very probable that an EPON OLT will implement a bridging functionality above the EPON interface layer, bridging between the EPON users and the network. Bridge functionality is specified at [802.1d]. In this scenario, the virtual ports of the EPON are corresponding to the virtual bridge ports. There is a direct mapping between the bridge ports and the LLIDs, which are virtual EPON channels.
EPON OLT很可能在EPON接口层之上实现桥接功能，即在EPON用户和网络之间桥接。网桥功能在[802.1d]中指定。在此场景中，EPON的虚拟端口与虚拟网桥端口相对应。网桥端口和LLID（虚拟EPON通道）之间存在直接映射。
Therefore, the bridge MIB modules ([RFC4188] and [RFC1525]) MAY be implemented when the EFM EPON MIB module is implemented for an EPON OLT, defining managed objects for the bridge layer.
因此，当为EPON OLT实现EFM EPON MIB模块时，可以实现网桥MIB模块（[RFC4188]和[RFC1525]），为网桥层定义托管对象。
The values of dot1dBasePortIfIndex would correspond to the ifIndex of the virtual port (1 for LLID1, 2 for LLID2, etc.).
dot1dBasePortIfIndex的值将对应于虚拟端口的ifIndex（1表示LLID1，2表示LLID2，等等）。
The broadcast virtual EPON interface of the OLT has no direct mapping to a virtual bridge port as it is not port specific but used for broadcast traffic.
OLT的广播虚拟EPON接口没有直接映射到虚拟网桥端口，因为它不是端口特定的，而是用于广播流量。
This section contains the mapping between the managed objects defined in this document and the attributes defined in [802.3ah], clause 30. The tables are divided into relevant groups.

The 'Queue report' field reports the occupancy of each uplink transmission queue. The number of queue sets defines the number of the reported sets, as would be explained in the description of the dot3ExtPkgQueueSetsTable table. For each set the report bitmap defines which queue is present in the report, meaning that although the MPCP REPORT message can report up to 8 queues in a REPORT message, the actual number is flexible. The Queue table has a variable size that is limited by the dot3ExtPkgObjectReportMaximumNumQueues object, as an ONU can have fewer queues to report. The entries in the table are control and status indication objects for managing the queues of an EPON interface that are gathered in an extended package as an addition to the objects that are based on the [802.3ah] attributes. Each object has a row for every virtual link and for every queue in the report. The LLID field, as defined in the [802.3ah], is a 2-byte register (15-bit field and a broadcast bit) limiting the
“队列报告”字段报告每个上行链路传输队列的占用情况。队列集的数量定义报告集的数量，如dot3ExtPkgQueueSetsTable表的说明所述。对于每个集合，报告位图定义报告中存在的队列，这意味着尽管MPCP报告消息最多可以报告报告消息中的8个队列，但实际数量是灵活的。队列表具有受dot3ExtPkgObjectReportMaximumNumQueues对象限制的可变大小，因为ONU可以有更少的队列进行报告。表中的条目是控制和状态指示对象，用于管理EPON接口的队列，这些队列作为基于[802.3ah]属性的对象的附加项收集在扩展包中。对于报表中的每个虚拟链接和每个队列，每个对象都有一行。[802.3ah]中定义的LLID字段是一个2字节寄存器（15位字段和广播位），用于限制

As can be seen from the message format, the ONU interface reports of the status of up to 8 queues
从消息格式可以看出，ONU接口报告最多8个队列的状态
and it can report in a single MPCP REPORT message
of a few sets of queues.
The number of queue_sets defines the number of the
reported sets, and it can reach a value of up to 8.
It means that an ONU can hold a variable number of
sets between 0 and 7.
The dot3ExtPkgQueueSetsTable table has a variable
queue_set size that is limited by the
dot3ExtPkgObjectReportMaximumNumThreshold object as an
ONU can have fewer queue_sets to report.
The 'Queue report' field reports the occupancy of each
uplink transmission queue. The queue_sets can be used to
report the occupancy of the queues in a few levels as to
allow granting, in an accurate manner, of only part of
the data available in the queues. A Threshold is
defined for each queue_set to define the level of the
queue that is counted for the report of the occupancy.
The threshold is reflected in the queue_set table by the
dot3ExtPkgObjectReportThreshold object.
For each queue set, the report bitmap defines which
queues are present in the report, meaning that
although the MPCP REPORT message can report of up to 8
queues in a REPORT message, the actual number is
flexible.
The dot3ExtPkgQueueSetsTable table has a variable queue
size that is limited by the
dot3ExtPkgObjectReportMaximumNumQueues object as an ONU
can have fewer queues to report.
Each object has a row for every virtual link, for each
queue in the report and for each queue_set in the queue.
The LLID field, as defined in the [802.3ah], is a 2-byte
register (15-bit field and a broadcast bit) limiting the
number of virtual links to 32768. Typically the number
of expected virtual links in a PON is like the number of

The user of this MIB module must therefore be aware that support for SET operations in a non-secure environment without proper protection can have a negative effect on network operations.
因此，此MIB模块的用户必须意识到，在没有适当保护的非安全环境中支持SET操作可能会对网络操作产生负面影响。
The readable objects in this MIB module (i.e., those with MAX-ACCESS other than not-accessible) may be considered sensitive in some environments since, collectively, they provide information about the performance of network interfaces and can reveal some aspects of their configuration. In such environments it is important to control even GET and NOTIFY access to these objects and possibly even to encrypt their values when sending them over the network via SNMP.
在某些环境中，此MIB模块中的可读对象（即具有MAX-ACCESS而非不可访问的对象）可能被视为敏感对象，因为它们共同提供有关网络接口性能的信息，并且可以揭示其配置的某些方面。在这样的环境中，控制甚至获取和通知对这些对象的访问，甚至在通过SNMP通过网络发送它们时加密它们的值，这一点很重要。
SNMP versions prior to SNMPv3 did not include adequate security. Even if the network itself is secure (for example by using IPsec), even then, there is no control as to who on the secure network is allowed to access and GET/SET (read/change/create/delete) the objects in this MIB module.
SNMPv3之前的SNMP版本未包含足够的安全性。即使网络本身是安全的（例如通过使用IPsec），即使如此，也无法控制安全网络上的谁可以访问和获取/设置（读取/更改/创建/删除）此MIB模块中的对象。
It is RECOMMENDED that implementers consider the security features as provided by the SNMPv3 framework (see [RFC3410], section 8), including full support for the SNMPv3 cryptographic mechanisms (for authentication and privacy).
建议实施者考虑SNMPv3框架所提供的安全特性（参见[RCFC310]，第8节），包括对SNMPv3加密机制的完全支持（用于身份验证和隐私）。
Further, deployment of SNMP versions prior to SNMPv3 is NOT RECOMMENDED. Instead, it is RECOMMENDED to deploy SNMPv3 and to enable cryptographic security. It is then a customer/operator responsibility to ensure that the SNMP entity giving access to an instance of this MIB module is properly configured to give access to the objects only to those principals (users) that have legitimate rights to indeed GET or SET (change/create/delete) them.
此外，不建议部署SNMPv3之前的SNMP版本。相反，建议部署SNMPv3并启用加密安全性。然后，客户/运营商应负责确保授予访问此MIB模块实例权限的SNMP实体已正确配置为仅授予那些拥有确实获取或设置（更改/创建/删除）对象的合法权限的主体（用户）访问对象。
