   described in clause 36.  The special EPON layers are added to the
   Ethernet layering in the following places:

   The MPCP is placed in the MAC control layer. layer, providing the EPON
   control protocol.  The Emulation layer, located at the RS
   (Reconciliation Sublayer), creates virtual private path to each ONU
   and the ONU.
   The FEC enhances layer is located between the PCS and PMA layers, enhancing

1.2.3.  The physical media

   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
   downlink is a broadcast media medium where the OLT transmits the data to
   all ONUs.  The uplink is a shared transmission
   media medium for all of the
   ONUs.  The uplink multiplexing access is based on time division multiplexing (TDM)
   and the management of the TDM media access is defined in by the Multi-Point Multi-
   Point control protocol (MPCP).  The upstream
   collisions are avoided through the transmission coordination done by
   the MPCP protocol.  The transmission is of one ONU at a time. control protocol based
   on an inband packet messaging.  The OLT send 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, defined in the [802.3ah] [802.3ah], is
   responsible to divide of allocating the BW and control controlling the delay of each
   ONU according to its SLA.

1.2.4.  PMD specifications

   The same wavelength optical wavelength plan as ITU-T G.983 the [ITU-T G.983] is selected.
   The transceivers are derivations from derivatives of existing Ethernet optics
   transceivers.  What is added is the optical
   transceivers, with dual wavelength on a single fiber and extended
   burst functionality capabilities for the uplink.  The uplink - burst capability is
   the burst transmission at functionality for the ONU ONUs and burst reception at
   functionality for the OLT.  The [802.3ah] selected very relaxed burst parameters.
   parameters to reduce the device cost of EPON products.

1.2.5.  Point to point emulation

   An emulated point-to-point

   The downstream is a broadcast link meaning the OLT transmission is created
   shared for each ONU. all ONUs.  The
   downstream sharing of the transmission is an aggregation of point-to-point tunnels the OLT has
   some negative privacy aspects, and single-copy-broadcast channel (tagged as all ones LLID). should be limited to broadcast
   traffic in nature only.  The
   ONUa filter traffic dedicated to each ONU should not
   be shared.  The solution provided by the [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 can not 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 ones 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 which is not intended for their reception reception, according to the
   virtual link marking.  An LLID tag is attached at the preamble to
   denote of the
   Ethernet packet denoting the virtual link - link.  The LLID marks the
   destination at port in the downstream and source at port in the upstream.

   The virtual links concept is also used to avoid violations 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 can
   not 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.

   The private paths concept
   means no solves the networking problems exist and it
   provides subscriber isolation.

   As the tunneling is only a virtual tunneling, there is a single
   physical interface and a single physical layer for the device
   including so that
   some attributes like are shared.  For example, the interface has a single
   local MAC address.

   The following diagram
   describes the virtual tunneling for an OLT with 3 ONUs, is illustrated in the EPON.

1.2.6.  Principles of the MPCP

   The EPON standard defines a media access control of an optical Access
   network.  The Access network has some substantial differences from
   the legacy LAN which the Ethernet was designed for.  The differences
   mainly lie 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 principles 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.

   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 8808 0x8808 Ethertype.  These messages are not
   forwarded
   from out of the MAC.

   A concept of time must exist in the protocol in order to schedule the
   uplink transmission.  The synchronized  A timestamp in which is set by the OLT and
   synchronized between the network units is managed passed through the MPCP
   messages.  The timestamp is also used to measure the RTT of each ONU and compensate it 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 20km distance which is
   equivalent to a 200usec RTT (25Kbytes of data).

   The TDM control is done using the
   gate GATE messages.  These messages define
   define, for each ONU ONU, the time for transmission and the length of
   transmission.  The RTT is reduced from the transmission time at in the gate
   GATE message to shift the ONU transmission time of the ONU in the
   opposite direction.

   A scheduling algorithm at the OLT, which is not defined in the

   efficient.  The closed loop is achieved by that MPCP allows the ONU reports ONUs to report on the amount of BW it
   they require for transmission. transmission using a special REPORT message.  This
   allows allocating BW to allocate an ONU only when requested, relying on the
   statistical burst property of the traffic, allowing different peak BW
   for each ONU different ONUs at different times using the
   statistical properties of the traffic times, hence allowing
   oversubscription of the BW.  The messages are for the BW report are denoted as REPORT
   messages which report message reports the amount of
   data waiting in the ONU queues.

   In addition to that the MPCP defines a protocol of auto-discovery and
   registration of ONUs.

   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 grant, allocated for that by the OLT.  During that
   time more than one ONU might try to register and register.  A collision in
   transmission might occur as the RTT of the new ONUs is not known yet a collision in transmission might occur. known.
   A random backoff mechanism of the transmission is used to schedule
   the next following registration requests to avoid these collisions.  When
   the OLT receives REG_REQUEST message of an ONU and approves this ONU
   then it sends a REGISTER message to this ONU defining its LLID.  From this
   time
   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 yet be needed to authenticate the ONU and allow it to
   participate in the network.

1.2.7.  Forward Error correction (FEC)

   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 and hence budget.  Hence an FEC which
   improves the link budget is very useful. budget, has a benefit.  The FEC code used is the
   RS(239,255,8), similar to G.975 the FEC code in [ITU-T G.975], improving
   the BER from 1E-4 to 1E-12.

   The FEC parity encapsulation is based on the framing of the Ethernet frames.
   packet.  The Ethernet frames packets are spaced by MAC rate adaptation, and
   the parity bytes are inserted after the packet, in the provided
   space.

   As the start and end of frame signals packet codewords define also the FEC
   boundaries, and they are outside of the FEC protection, they are
   replaced by a series of symbols to enhance reduce their vulnerability to
   errors.

   The following diagram presents an FEC protected frame:

   +-------------------------------------------------------------------+
   |       |              |           |     |       |          |       |
   | S_FEC | Preamble/SFD |   Frame   | FCS | T_FEC |  Parity  | T_FEC |

   +-------------------------------------------------------------------+

   The FEC is added in a separate layer between the PCS and PMA layers
   of the [802.3].

   The FEC layer introduces a fixed delay in the receive path and transmit
   path.

   The FEC layer is optional.

1.3.  Management architecture

   Each one of the EPON layers is accompanied by with a management I/F,
   interface, which is controlled through clause 30 of the spec.  The MIB document
   allocates for each one of them a separate package, as [802.3ah].
   As the [802.3ah] spec may be used for different applications and may use some
   of the clauses separately. may be used separately, the IEEE management clause
   allocates for each one of them a separate package.  The MIB document
   follows this partition.

   As

   The association is strait forward for the ONU the situation is simple. interface.  There is
   one logical and one physical interface and a single copy exists for
   each layer which layer, that can be remotely queried by the OLT.

   At the OLT there is a single physical interface and N virtual logical
   interfaces for the virtual links of the ONUs ( and (and another virtual
   interface for the broadcast virtual link).  As can be seen from the
   layering diagram above, the MAC layer is virtually duplicated and therefore
   the selection for duplicated.

   Therefore in this document it was selected that the management for this scenario of a
   virtual interface is to allocate like a physical interface and an interface index
   is allocated for each one of the virtual link links and an additional
   interface index is allocated for the OLT.  Therefore the Interface, MAU and
   etherLike interfaces MIBs have a row (ifIndex) for each virtual link
   at

   To illustrate the OLT. interface modeling, consider two devices.  The justification for this partition
   first device has two physical interfaces, is that typically located at a
   consumer's site, and called an "ONU modem".

   An "ONU modem" is shown in the
   interfaces are quite well separated as they present physical
   different ONUs which are viewed from figure below:

                            --------
             ONU interface | ONU   | 10megabit interface
             --------------| modem |--------------------
                           ---------

   This device would have 3 entries in the OLT point of view, IF table, and one IF stack
   entry, for
   instance there is a meaning example:

   ifIndex=1 - interface for a separate bad frames, or bad octets
   counters 10megabit interface

   ifIndex=2 - interface for each virtual link as the optical interface

   ifIndex=200 - interface for the ONU interface

   And then in IF stack table:

   ifStackHigherLayer=200, ifStackLowerLayer=2 - map between the
   physical and the ONU

   The second device has three physical interfaces, is typically located
   at the provider's site, and may be called a "headend".

   A "headend" is shown in the figure below:

                               ---------
             1st OLT interface | Head  | gigE interface
             ------------------| end   |--------------------
                               |       |
             ------------------|       |
             2nd OLT interface |       |
                               ---------
   This device would have 5 entries (when no attached ONUs) in the IF
   table, for example:

   ifIndex=1 - interface for gigE interface

   ifIndex=2 - interface for 1st optical interface

   ifIndex=3 - interface for 2nd optical interface

   ifIndex=265535 - interface for the 1st OLT broadcast interface

   ifIndex=365535 - interface for the 2nd OLT broadcast interface

   And then in IF stack table:

   ifStackHigherLayer=265535, ifStackLowerLayer=2 - map between the 1st
   physical and its broadcast interface

   ifStackHigherLayer=365535, ifStackLowerLayer=3 - map between the 2nd
   physical and its broadcast interface

   If two ONUs connected to the first OLT interface, then for example,
   the following entries would be added to the IF table:

   ifIndex=200001 - interface for the 1st ONU of 1st OLT

   ifIndex=200002 - interface for the 2nd ONU of 1st OLT

   And in the IF stack table:

   ifStackHigherLayer=200001, ifStackLowerLayer=2 - map between the 1st
   physical and 1st ONU

   ifStackHigherLayer=200002, ifStackLowerLayer=2 - map between the 1st
   physical and 2nd ONU

   For each physical interface, there would be an entry (ifIndex) in the
   tables of the interface MIB module [RFC2863], MAU MIB module
   [RFC3636] 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 distanced
   differently, which differently
   distanced.  This is quite similar to a case of separate physical interface.
   interfaces.

   The same partition concept exists for the MIB module of this
   document.  Each row in the tables is selected indexed according to the ifIndex
   and specifically there is a row for each virtual link.  There are a few
   some control objects which are defined shared and are the same for the entire layer
   virtual interfaces (and they should have the same value for each
   ifIndex) but most of the objects are partitioned into have different values for N+1
   logical interfaces at the OLT OLT.  This is done for each layer. MIB group.  It
   is a bit different than from the IEEE [802.3ah] layering diagram which present presents
   the P2MP layer as a single layer while duplicating the MAC and MAC
   client layers (Please see the diagram above).  However from
   management perspective it is more convenient and neat to partition
   the management of the entities layers for the virtual links links, as the
   managed atomic
   managed entity is the virtual link, and link.  It is also convenient to use the
   interface index of the virtual link for that purpose purpose, as it is
   already used for to index the rows of the virtual links at the Interface,
   MAU and etherLike interfaces MIBs.

   As an example provided below are

   and clause 65 EPON FEC attributes.  The following table is presented
   in this group:

   The dot3EponFecTable defines the objects used for the configuration

   compliant interfaces.

   iv) The EPON extended package MIB objects - MIB objects used for
   configuration and status indication with extended capabilities of the
   EPON interfaces.  The following tables are presented in this group:

   The dot3ExtPkgControlTable defines the objects which are per logical
   link, used for the configuration and status indication of EPON
   compliant interfaces.

   The dot3ExtPkgQueueTable defines the objects which are per logical
   link, and per queue, used for the configuration and status indication
   of the ONU queues reported in the MPCP REPORT message, of EPON
   compliant interfaces.

   The dot3ExtPkgQueueSetsTable defines the objects which are per
   logical link, per queue, and per queue_set, used for the
   configuration and status indication of the ONU queue_sets reported in
   the MPCP REPORT message, of EPON compliant interfaces.

   The dot3ExtPkgOptIfTable defines the objects which are per logical
   link, used for the control and status indication of the optical
   interface of EPON compliant interfaces.

   As described in the architecture section, each row in the tables is
   indexed according to the ifIndex, and specifically there is a row for
   each virtual link.  There are a few control objects which 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
   management perspective it is more convenient and neat to partition
   the management of the layers for the virtual links, as the atomic

   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.

                                  Table 3

   ONU1_MAC_Address is the MAC address of ONU1 EPON interface.

   ONU2_MAC_Address is the MAC address of ONU2 EPON interface.

   ONU3_MAC_Address is the MAC address of ONU3 EPON interface.

   BRCT_MAC_Address is the MAC address of the broadcast EPON interface,
   which is the OLT MAC address.

   The creation of the rows of the OLT interface and the broadcast
   virtual interface is done at initialization.

   The creation of rows of the virtual interfaces at the OLT is done
   when the link is established (ONU registers) and the deletion is done
   when the link is deleted (ONU deregisters).

   For example, provided below are the values of the MPCP control table
   of the OLT after initialization, before the ONUs register.

     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

   BRCT_MAC_Address is the MAC address of the broadcast EPON interface,
   which is the OLT MAC address.

3.  Relation to other MIB Modules

3.1.  Relation to the Interfaces MIB and Ethernet-like Interfaces MIB

   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.

   Implementing this module therefore MUST require implementation of the
   Interfaces MIB module [RFC2863] and the Ethernet-like Interfaces MIB
   module [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.

   In this document there is no replication of the objects from these
   MIBs, so for instance the document is defining
   dot3MpcpRemoteMACAddress only while assuming the local MAC address
   object is already defined in [RFC3635].

   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.

   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.

   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.

   For example the values of the Interface MIB objects are presented in
   the following tables, for an OLT with 3 registered ONUs:

    The table below presents the objects of the Interface MIB of an ONU
                             in working mode.

   The creation of the rows at the ONU and at the OLT, for the OLT
   interface and the broadcast virtual interface is done at
   initialization.  The creation and deletion of rows at the OLT for the
   virtual link interfaces is done when the link is established (ONU
   registers) and when the link is deleted (ONU deregisters).

   As an example, provided below are the values for the MPCP control
   table after initialization:

2.  MIB structure

   This document defines MAC address of the DOT3 OLT EPON MIB module. interface.

   The DOT3 EPON MIB
   module defines the objects used for configuration and description of
   the [802.3ah] Point to Multipoint (P2MP) section.  These MIB module
   objects are included following values will be set in four MIB module groups.

   The Multi-Point Control Protocol (MPCP) MIB objects - MIB objects
   related to [802.3ah] clause 64 Multi Point Control Protocol
   attributes.  In this MIB module group: The dot3MpcpControlTable
   defines the objects used for the configuration ifStack and status indication,
   which are per logical link, of MPCP layer ([802.3ah] Multi-Point
   Control Protocol) compliant interfaces.  The dot3MpcpStatTable
   defines the statistics objects, which are per logical link, for MPCP
   compliant interfaces.

   The OMPEmulation MIB objects - MIB module ifInvStack tables
   related to [802.3ah] clause
   65 point to point emulation attributes.  In this MIB module group:
   The dot3OmpEmulationTable defines the objects used for the
   configurations and status indications which are per logical link, of
   OMPEmulation compliant interfaces.  The dot3OmpEmulationStatTable
   defines the statistics objects, which are per logical link, for
   OMPEmulation compliant interfaces.

   The FEC MIB module objects example:

   ifStackTable:

   ifStackHigherLayer=265535, ifStackLowerLayer=2 - managed object related to [802.3ah]
   clause 60 and clause 65 EPON FEC attributes.  The dot3EponFecTable
   defines the objects used for map between the configurations OLT
   physical interface and status
   indications, which are per logical link, of FEC EPON compliant
   interfaces.

   The EPON extended package MIB objects defining its broadcast virtual interface

   ifStackHigherLayer=200001, ifStackLowerLayer=2 - map between the objects used for
   configuration OLT
   physical interface and description of management objects for extended
   capabilities its virtual interface of the EPON interfaces.  The dot3ExtPkgControlTable
   defines the extended package objects, which are per logical link,
   used for 1st ONU

   ifStackHigherLayer=200002, ifStackLowerLayer=2 - map between the configuration OLT
   physical interface and status indication its virtual interface of the EPON
   interfaces.  The dot3ExtPkgQueueTable defines the extended package
   objects, which are per logical link, and per REPORT queue used for 2nd ONU

   ifStackHigherLayer=200003, ifStackLowerLayer=2 - map between the configuration OLT
   physical interface and status indication its virtual interface of the 3rd ONU queues reported at

   ifInvStackTable:

   ifStackLowerLayer=2, ifStackHigherLayer=265535, - map between the MPCP REPORT message
   broadcast interface of the EPON interfaces.  The
   dot3ExtPkgQueueSetsTable defines the extended package objects, which
   are per logical link per REPORT queue, OLT and per queue_set used for the
   configuration OLT physical interface

   ifStackLowerLayer=2, ifStackHigherLayer=200001 - map between the OLT
   virtual interface of the 1st ONU and status indication the OLT physical interface

   ifStackLowerLayer=2, ifStackHigherLayer=200002 - map between the OLT
   virtual interface of the 2nd ONU queue_sets reported at and the MPCP REPORT message OLT physical interface

   ifStackLowerLayer=2, ifStackHigherLayer=200003 - map between the OLT
   virtual interface of the EPON interfaces. 3rd ONU and the OLT physical interface

   The
   dot3ExtPkgOptIfTable defines rows for the extended package objects, which are
   per logical link, used ONU interface, for the control OLT interface and status indication of for the
   optical interfaces OLT
   broadcast interface are created in initialization.

   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).

   The EPON interfaces.

3.  Relation to other MIB Modules

3.1.  Relation to module also extends the Interfaces MIB and Ethernet-like Interfaces Interface MIB

   EPON interfaces are module with a type set
   of Ether-like counters, which are specific for the EPON interface.  This  The EPON MIB
   module
   extends implements the objects same handling of the Ehter-like interfaces management for counters when the
   operation of the
   EPON type interfaces.  Thus, each managed EPON interface would have a
   corresponding entry in starts or stops.  The interface MIB
   document describes the mandatory tables possible behavior of counters when an
   interface is re-initialized using the Ether-like MIB
   module found in [RFC3635], and likewise in ifCounterDiscontinuityTime
   indicator, indicating the tables from discontinuity of the
   Interface counters.  Please see
   [RFC2863] section 3.1.5 p.11 for more information.  The counters of
   the EPON MIB module found should be handled in [RFC2863].  Also each managed virtual
   EPON interface defined by a similar manner.

3.2.  Relation to the virtual link at IEEE 802.3 MAU MIBs

   The MAU types of the OLT would have a
   corresponding entry EPON Interface are defined in the mandatory tables amended MAU
   MIB document.  This document assumes the implementation of the Ether-like MAU
   MIB
   module found in [RFC3635], for this purpose and likewise in does not repeat the tables from EPON MAU types.
   Therefore implementing this module MUST require implementation of the
   Interface MIB
   MAU-MIB module found in [RFC2863] with a dedicated ifIndex.

   There is no replication [RFC3636bis-03].

   The handling of the objects from these RFCs, so ifMAU tables for
   instance the document EPON case is defining dot3MpcpRemoteMACAddress only while
   assuming similar to the local MAC address attribute is already defined in
   [RFC3635]

   Interface Indexes as specified in [RFC2863] are used
   handling described in these MIB
   Modules.  The descriptions of the ifIndexes denote which ifIndex is
   being used.  The use of ifIndex is former section for actual existing connections the Interface and Ether-
   like interface MIBs.  A single row exists for the virtual links at the OLT.  The OLT interface and ONU in the
   ifMauTable.  A row for each virtual link interfaces are stacked using (N+1 rows) exists at the ifStack table
   OLT, with a separate value of ifMauIfIndex for each virtual link.

   As specified
   at [RFC2863] and above the ifInvStack defined in [RFC2864].  At rows for the OLT ONU interface, for the OLT
   interface and the virtual links associated with it are stacked as for the OLT broadcast interface are created in
   initialization.

   The creation of a row for a virtual link is done when the higher layer of all other interfaces related
   to virtual
   link is established (ONU registers) and deletion is done when the
   virtual links.

   In this MIB module link is deleted (ONU deregisters).

3.3.  Relation to the interface referred EFM OAM MIB

   The EPON interfaces are aimed to is the OLT interface optical access networks and most
   probably will be accompanied with the sub-layers defined in implementation of the [802.3ah] for OAM
   section of the OLT are also divided
   into virtual links. [802.3ah].  Therefore the ifIndexs used in the EFM OAM MIB document module
   [I-D.ietf-hubmib-efm-mib] MAY be implemented, when this MIB module is
   implemented, defining managed objects for the OLT OAM layer that are
   complementary to the ifIndex of the OLT and EFM EPON MIB module.  As the ifIndexes of OAM is defined for
   a point to point link it is implemented in this case, using the
   virtual links.  Information links which are defined for each LLID in the tables P2MP network, so that an
   instance is indexed by
   the interface index held for each table.  This index is Logical link (LLID) of the EPON.  The
   corresponding to ifIndex of the virtual link interfaces ifIndexs.

   Only the MAC address at the OLT is not duplicated used as the physical
   interface is ifIndex of
   the same. tables of the OAM MIB module, for this purpose.

3.4.  Relation to the bridge MIB

   It is specified in very probable that an EPON OLT will implement a bridging
   functionality above the [802.3ah] section
   64.1.2.  At EPON interface layer, bridging between the tables this entry
   EPON users and the network.  Bridge functionality is duplicated for specified at
   [802.1d].  In this scenario the virtual
   interfaces.

   Implementing this module therefore MUST require implementation ports of
   Interfaces MIB module [RFC2863] and Ethernet-like Interfaces MIB
   module [RFC3635].

   As an example here the EPON are
   corresponding to the values for virtual bridge ports.  There is a direct mapping
   between the Interface MIB for an OLT
   with 3 ONUs registered:

                        At bridge ports and the ONU in working mode:

       +----------------------+-----------------------------------+

   implemented when the EFM EPON MIB module is implemented for an EPON
   OLT, defining managed objects for the bridge layer.

   The values of dot1dBasePortIfIndex would correspond to the ifIndex of
   the virtual port (1 for LLID1, 2 for LLID2,...)

   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.

       DESCRIPTION
               "The objects in this MIB module MUST require implementation of MAU-MIB
   module [RFC3636].  For the ONU there is a single row for are used to manage the
   ifMauTable.  At

                Network(EPON) Interfaces as defined in IEEE P802.3ah
                clause 60,64,65.
            The following reference is a row for each virtual link (N+1),
   ifMauIfIndex has a value for each virtual link.

   As specified above the creation of the rows at the ONU used throughout this MIB module:
              [802.3ah] refers to:
                Information technology - Telecommunications and at the OLT
   for the OLT interface
                information exchange between systems - Local and for the broadcast virtual index, is done at

                access networks. IEEE Std 802.3ah-2004, October 2004.

             Of particular interest are aimed Clause 64(Multi-Point Control
             Protocol - MPCP), Clause 65(Point to the access optical networks Multipoint
             Reconciliation Sublayer - P2MP RS), Clause 60 (Ethernet
             Passive Optical Network Physical Medium Dependent - EPON
             PMDs), Clause 30, 'Management', and most
   probably will be followed by implementation of the OAM section of the
   [802.3ah].  Therefore Clause 45, 'Management
             Data Input/Output (MDIO) Interface'.

   If the OLT supports bridging then the virtual physical interfaces are

               "A table for extended package Queue management objects.
                The [802.3ah] MPCP uses for the feedback BW request from
                the ONUs a report count of some queues occupancy. These queues
                serve the ONU transmission and data is gathered there
                until the ONU is granted for transmission. Since the
                existence number of such queuing mechanism is implied in the

                mainly to gather some statistics of their operation.
                Entries are control and status indication
                objects for an EPON interface which are gathered in an

6.  IANA Considerations

   The DOT3 EPON MIB module requires the allocation of a single object
   identifier for its MODULE-IDENTITY under the MIB-2 tree.

   The MIB module in this document uses the following IANA-assigned
   OBJECT IDENTIFIER values recorded in the SMI Numbers registry:

         Descriptor        OBJECT IDENTIFIER value
         ----------        -----------------------

         dot3EponMIB        { mib-2 XXX }

   Editor's Note (to be removed prior to publication): the IANA is
   requested to assign a value for "XXX" under the 'mib-2' subtree and
   to record the assignment in the SMI Numbers registry.  When the
   assignment has been made, the RFC Editor is asked to replace "XXX"
   (here and in the MIB module) with the assigned value and to remove
   this note.

7.  Security Considerations

   There are number of managed objects defined in this MIB module that
   have a MAX-ACCESS clause of read-write or read-create.  Writing to
   these objects can have potentially disruptive effects on network
   operation: Including:

   Changing dot3MpcpAdminState state (Writing can be done at any time)

   Changing dot3EponFecMode mode (Writing can be done at any time)

   Changing dot3ExtPkgObjectReset mode (Writing can be done at any time)

   Changing dot3ExtPkgObjectFecEnabled mode (Writing can be done at any
   time)

   Changing dot3ExtPkgObjectPowerDown (Writing can be done at any time)

   Changing dot3ExtPkgObjectReportNumThreshold (Writing can be done at
   any time)

   Changing dot3ExtPkgObjectReportThreshold (Writing can be done at any
   time)

   Changing dot3ExtPkgObjectRegisterAction (Writing can be done at any
   time)

   Changing dot3ExtPkgRMadlEntryStatus (Writing can be done at any time)

   Changing dot3ExtPkgOptIfLowerInputPowerThreshold (Writing can be done
   at any time)

   Changing dot3ExtPkgOptIfUpperInputPowerThreshold (Writing can be done
   at any time)

   Changing dot3ExtPkgOptIfLowerOutputPowerThreshold (Writing can be
   done at any time)

   Changing dot3ExtPkgOptIfUpperOutputPowerThreshold (Writing can be
   done at any time)

   Changing dot3ExtPkgOptIfTransmitEnable (Writing can be done at any
   time)

   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.

   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.

   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.

   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).

   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.
