RFC 5066                  EFMCu Interfaces MIB             November 20071.  Introduction   New Ethernet-like interfaces have been defined in the Institute of   Electrical and Electronics Engineers (IEEE) Standard 802.3ah-2004   [802.3ah], a.k.a.  Ethernet in the First Mile (EFM), which is now a   part of the base IEEE Standard 802.3-2005 [802.3].  In particular,   2BASE-TL and 10PASS-TS physical interfaces (PHYs), defined over   voice-grade copper pairs, have been specified for the long and short   reach, respectively.  These interfaces, collectively called EFM   Copper (EFMCu), are based on Single-pair High-speed Digital   Subscriber Line (SHDSL) [G.991.2] and Very High speed Digital   Subscriber Line (VDSL) [G.993.1] technology, supporting optional   Physical Medium Entity (PME) aggregation (a.k.a. multi-pair bonding)   with variable rates.   2BASE-TL PHY is capable of providing at least 2 Mbps over a 2700 m   long single copper pair with a mean Bit Error Rate (BER) of 10^-7   (using 5 dB target noise margin).   10PASS-TS PHY is capable of providing at least 10 Mbps over a 750 m   long single copper pair with a mean BER of 10^-7 (using 6 dB target   noise margin).   This memo defines a Management Information Base (MIB) module for use   with network management protocols in the Internet community to manage   EFMCu interfaces.  In addition, a MIB module is defined describing   the cross-connect capability of a stacked interface.   Note that managed objects for Operation, Administration and   Maintenance (OAM) and Ethernet over Passive Optical Networks (EPON)   clauses of IEEE 802.3ah are defined in EFM-COMMON-MIB [RFC4878] and   EFM-EPON-MIB [RFC4837], respectively.2.  The Internet-Standard Management Framework   For a detailed overview of the documents that describe the current   Internet-Standard Management Framework, please refer tosection 7 of   RFC 3410 [RFC3410].   Managed objects are accessed via a virtual information store, termed   the Management Information Base or MIB.  MIB objects are generally   accessed through the Simple Network Management Protocol (SNMP).   Objects in the MIB are defined using the mechanisms defined in the   Structure of Management Information (SMI).  This memo specifies MIB   modules that are compliant to the SMIv2, which is described in STD   58,RFC 2578 [RFC2578], STD 58,RFC 2579 [RFC2579] and STD 58,RFC2580 [RFC2580].Beili                       Standards Track                     [Page 3]

RFC 5066                  EFMCu Interfaces MIB             November 2007   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",   "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this   document are to be interpreted as described inRFC 2119 [RFC2119].3.  Relation to Other MIB Modules   This section outlines the relationship of the MIB modules defined in   this document with other MIB modules described in the relevant RFCs.   Specifically, the Interfaces Group MIB (IF-MIB), Ethernet-Like   (EtherLike-MIB), MAU (MAU-MIB), SHDSL (HDSL2-SHDSL-LINE-MIB), and   VDSL (VDSL-LINE-EXT-MCM-MIB) modules are discussed.3.1.  Relation to Interfaces Group MIB Module   2BASE-TL and 10PASS-TS PHYs specified in the EFM-CU-MIB module are   stacked (a.k.a. aggregated or bonded) Ethernet interfaces and as such   are managed using generic interface management objects defined in the   IF-MIB [RFC2863].   The stack management (i.e., actual connection of the sub-layers to   the top-layer interface) is done via the ifStackTable, as defined in   the IF-MIB [RFC2863], and its inverse ifInvStackTable, as defined in   the IF-INVERTED-STACK-MIB [RFC2864].   The new tables ifCapStackTable and its inverse ifInvCapStackTable   defined in the IF-CAP-STACK-MIB module below, extend the stack   management with an ability to describe possible connections or cross-   connect capability, when a flexible cross-connect matrix is present   between the interface layers.3.1.1.  Layering Model   An EFMCu interface can aggregate up to 32 Physical Medium Entity   (PME) sub-layer devices (modems), using the so-called PME Aggregation   Function (PAF).   A generic EFMCu device can have a number of Physical Coding Sublayer   (PCS) ports, each connected to a Media Access Controller (MAC) via a   Medium Independent Interface (MII) at the upper layer, and cross-   connected to a number of underlying PMEs, with a single PCS per PME   relationship.  See clause 61.1 of [802.3ah] for more details.   Each PME in the aggregated EFMCu port is represented in the Interface   table (ifTable) as a separate interface with ifType of shdsl(169) for   2BASE-TL or vdsl(97) for 10PASS-TS.  The ifType values are defined in   [IANAifType-MIB].Beili                       Standards Track                     [Page 4]

RFC 5066                  EFMCu Interfaces MIB             November 2007   ifSpeed for each PME SHALL return the actual data bitrate of the   active PME (e.g., for 2BaseTL PMEs it is a multiple of 64 Kbps).  A   zero value SHALL be returned when the PME is Initializing or Down.   The ifSpeed of the PCS is the sum of the current operating data rates   of all PMEs in the aggregation group, without the 64/65-octet   encapsulation overhead and PAF overhead, but accounting for the   Inter-Frame Gaps (IFGs).   When using the stated definition of ifSpeed for the PCS, there would   be no frame loss in the following configuration (the test-sets are   configured to generate 100% of back-to-back traffic, i.e., minimal   IFG, at 10 or 100 Mbps, with min and max frame sizes; the EFM   interfaces are aggregated, to achieve the shown speed):      .-------.           .--.           .---.           .-------.      |testset|--10BaseT--|CO|--2BaseTL--|CPE|--10BaseT--|testset|      '-------'           '--'           '---'           '-------'        ifSpeed= 10 Mbps        10 Mbps         10 Mbps      .-------.            .--.            .---.            .-------.      |testset|--100BaseT--|CO|--10PassTS--|CPE|--100BaseT--|testset|      '-------'            '--'            '---'            '-------'        ifSpeed= 100 Mbps        100 Mbps         100 Mbps            Figure 1: Example configuration with no frame lossBeili                       Standards Track                     [Page 5]

The ifInvStackTable, being an inverted version of the   ifStackTable, provides an efficient means for a Network Management   application to read a subset of the ifStackTable and thereby   determine which PCS runs on top of a particular PME.   A new table ifCapStackTable, defined in the IF-CAP-STACK-MIB module,   specifies for each higher-layer interface (e.g., PCS port) a list of   lower-layer interfaces (e.g., PMEs), which can possibly be cross-   connected to that higher-layer interface, determined by the cross-   connect capability of the device.  This table, modeled after   ifStackTable, is read-only, reflecting current cross-connect   capability of stacked interface, which can be dynamic in some   implementations (e.g., if PMEs are located on a pluggable module and   the module is pulled out).  Note that PME availability per PCS,   described by ifCapStackTable, can be constrained by other parameters,   for example, by aggregation capacity of a PCS or by the PME in   question being already connected to another PCS.  So, in order toBeili                       Standards Track                     [Page 6]

RFC 5066                  EFMCu Interfaces MIB             November 2007   ensure that a particular PME can be connected to the PCS, all   respective parameters (e.g., ifCapStackTable, ifStackTable, and   efmCuPAFCapacity) SHALL be inspected.   The ifInvCapStackTable, also defined in the IF-CAP-STACK-MIB module,   describes which higher-layer interfaces (e.g., PCS ports) can   possibly be connected to a particular lower-layer interface (e.g.,   PME), providing an inverted mapping of the ifCapStackTable.  While it   contains no additional information beyond that already contained in   the ifCapStackTable, the ifInvCapStackTable has the ifIndex values in   its INDEX clause in the reverse order, i.e., the lower-layer   interface first, and the higher-layer interface second, providing an   efficient means for a Network Management application to read a subset   of the ifCapStackTable and thereby determine which interfaces can be   connected to run on top of a particular interface.3.1.2.  PME Aggregation Function (PAF)   The PME Aggregation Function (PAF) allows a number of PMEs to be   aggregated onto a PCS port, by fragmenting the Ethernet frames,   transmitting the fragments over multiple PMEs, and assembling the   original frames at the remote port.  PAF is OPTIONAL, meaning that a   device with a single PME MAY perform fragmentation and re-assembly if   this function is supported by the device.  Note however that the   agent is REQUIRED to report on the PAF capability for all EFMCu ports   (2BASE-TL and 10PASS-TS).   The EFM-CU-MIB module allows a Network Management application to   query the PAF capability and enable/disable it if supported.  Note   that enabling PAF effectively turns on fragmentation and re-assembly,   even on a single-PME port.3.1.3.  Discovery Operation   The EFMCu ports may optionally support discovery operation, whereby   PMEs, during initialization, exchange information about their   respective aggregation groups (PCS).  This information can then be   used to detect copper misconnections or for an automatic assignment   of the local PMEs into aggregation groups instead of a fixed pre-   configuration.   The MIB modules defined in this document allow a Network Management   application to control the EFM Discovery mechanism and query its   results.  Note that the Discovery mechanism can work only if PAF is   supported and enabled.Beili                       Standards Track                     [Page 7]

RFC 5066                  EFMCu Interfaces MIB             November 2007   Two tables are used by the EFM Discovery mechanism: ifStackTable and   ifCapStackTable.  The following pseudo-code gives an example of the   Discovery and automatic PME assignment for a generic PAF-enabled   multi-PCS EFMCu device, located at Central Office (CO), using objects   defined in these MIB modules and in the IF-MIB (Note that automatic   PME assignment is only shown here for the purposes of the example.   Fixed PME pre-assignment, manual assignment, or auto-assignment using   an alternative internal algorithm may be chosen by a particular   implementation): // Go over all PCS ports in the CO device FOREACH pcs[i] IN CO_device { // Perform discovery and auto-assignment only on PAF enabled ports   // with room for more PMEs   IF ( pcs[i].PAFSupported AND pcs[i].NumPMEs < pcs[i].PAFCapacity )   { // Assign a unique 6-octet local discovery code to the PCS     // e.g., MAC address     dc = pcs[i].DiscoveryCode = MAC[i];     // Go over all disconnected PMEs, which can     // potentially be connected to the PCS     FOREACH pme[j] IN ifCapStackTable[pcs[i]] AND                    NOT IN ifStackTable[pcs[i]]  // not connected     { // Try to grab the remote RT_device, by writing the value       // of the local 6-octet discovery code to the remote       // discovery code register (via handshake mechanism).       // This operation is atomic Set-if-Clear action, i.e., it       // would succeed only if the remote discovery register was       // zero.

Go to the next PCS.       BREAK;     }   } }   An SNMP Agent for an EFMCu device builds the ifCapStackTable and its   inverse ifInvCapStackTable according to the information contained in   the Clause 45 PME_Available_register (see [802.3ah] 61.1.5.3 and   45.2.3.20).   Adding a PME to the ifStackTable row for a specific PCS involves   actual connection of the PME to the PCS, which can be done by   modifying Clause 45 PME_Aggregate_register (see [802.3ah] 61.1.5.3   and 45.2.3.21).   Note that the PCS port does not have to be operationally 'down' for   the connection to succeed.  In fact, a dynamic PME addition (and   removal) MAY be implemented with an available PME being initialized   first (by setting its ifAdminStatus to 'up') and then added to an   operationally 'up' PCS port, by modifying a respective ifStackTable   (and respective ifInvStackTable) entry.   It is RECOMMENDED that a removal of the last operationally 'up' PME   from an operationally 'up' PCS would be rejected by the   implementation, as this action would completely drop the link.3.1.4.  EFMCu Ports Initialization   EFMCu ports being built on top of xDSL technology require a lengthy   initialization or 'training' process, before any data can pass.   During this initialization, both ends of a link (peers) work   cooperatively to achieve the required data rate on a particularBeili                       Standards Track                     [Page 9]

Sometimes, when the copper line is too long or the   noise on the line is too high, that 'training' process may fail to   achieve a specific target rate with required characteristics.   The ifAdminStatus object from the IF-MIB controls the desired state   of a PCS with all the PMEs connected to it or of an individual PME   port.  Setting this object to 'up' instructs a particular PCS or PME   to start the initialization process, which may take tens of seconds   for EFMCu ports, especially if PAF is involved.  The ifOperStatus   object shows the operational state of an interface (extended by the   ifMauMediaAvailable object from MAU-MIB for PCS and   efmCuPmeOperStatus defined in the EFM-CU-MIB module for PME   interfaces).   A disconnected PME may be initialized by changing the ifAdminState   from 'down' to 'up'.  Changing the ifAdminState to 'up' on the PCS   initializes all PMEs connected to that particular PCS.  Note that in   case of PAF some interfaces may fail to initialize while others   succeed.  The PCS is considered operationally 'up' if at least one   PME aggregated by its PAF is operationally 'up'.  When all PMEs   connected to the PCS are 'down', the PCS SHALL be considered   operationally 'lowerLayerDown'.  The PCS SHALL be considered   operationally 'notPresent' if it is not connected to any PME.  The   PCS/PME interface SHALL remain operationally 'down' during   initialization.   The efmCuPmeOperStatus defined in the EFM-CU-MIB module expands PME's   ifOperStatus value of 'down' to 'downReady', 'downNotReady', and   'init' values, indicating various EFMCu PME-specific states.3.1.5.  Usage of ifTable   Both PME and PCS interfaces of the EFMCu PHY are managed using   interface-specific management objects defined in the EFM-CU-MIB   module and generic interface objects from the ifTable of IF-MIB, with   all management table entries referenced by the interface index   ifIndex.

Relation to SHDSL MIB Module   G.SHDSL.bis modems, similar to PMEs comprising a 2BASE-TL port, are   described in the HDSL2-SHDSL-LINE-MIB module [RFC4319].  Note that   not all attributes of G.SHDSL modems reflected in the HDSL2-SHDSL-   LINE-MIB module have adequate management objects (Clause 30   attributes and Clause 45 registers) in the EFM standard.   Because of these differences and for the purposes of simplicity,   unification of attributes common to both 2BASE-TL and 10PASS-TS PMEs,   and name consistency (e.g., prefixing the 2BASE-TL PME related   objects with 'efmCuPme2B' instead of 'hdsl2shdsl'), it was decided   not to reference HDSL2-SHDSL-LINE-MIB objects, but define all the   relevant objects in the EFM-CU-MIB module.   However, if some functionality not available in the EFM-CU-MIB module   is required and supported by the PME, e.g., performance monitoring,   relevant HDSL2-SHDSL-LINE-MIB groups MAY be included and applied for   PMEs of 2BASE-TL subtype.Beili                       Standards Track                    [Page 11]

Relation to VDSL MIB Module   VDSL modems, similar to the PME(s) comprising a 10PASS-TS port, are   described in the VDSL-LINE-EXT-MCM-MIB module [RFC4070].  Note that   not all attributes of VDSL modems reflected in the VDSL-LINE-EXT-MCM-   MIB module have adequate management objects (Clause 30 attributes and   Clause 45 registers) in the EFM standard.   Because of these differences and for the purposes of simplicity,   unification of attributes common to both 2BASE-TL and 10PASS-TS PMEs,   and name consistency, it was decided not to reference VDSL-LINE-EXT-   MCM-MIB objects, but define all the relevant objects in the EFM-CU-   MIB module.   However, if some functionality not available in the EFM-CU-MIB module   is required and supported by the PME, relevant VDSL-LINE-EXT-MCM-MIB   groups MAY be included and applied for PMEs of 10PASS-TS subtype.3.4.  Relation to Ethernet-Like and MAU MIB Modules   The implementation of the EtherLike-MIB [RFC3635] and MAU-MIB   [RFC4836] modules is REQUIRED for EFMCu interfaces.   Two new values of ifMauType (OBJECT-IDENTITIES of dot3MauType) and   corresponding bit definitions of ifMauTypeListBits   (IANAifMauTypeListBits) have been defined in the IANA-MAU-MIB module   [RFC4836] for EFMCu MAUs:   o  dot3MauType2BaseTL and b2BaseTL - for 2BASE-TL MAU   o  dot3MauType10PassTS and b10PassTS - for 10PASS-TS MAU   Additionally, the IANA-MAU-MIB module defines two new values of   ifMauMediaAvailable, specifically for EFMCu ports: availableReduced   and ready (in textual convention IANAifMauMediaAvailable).  Due to   the PME aggregation, the EFMCu interpretation of some possible   ifMauMediaAvailable values differs from other MAUs as follows:   o  unknown - the EFMCu interface (PCS with connected PMEs) is      Initializing   o  ready - the interface is Down, at least one PME in the aggregation      group (all PMEs connected to the PCS) is ready for handshake   o  available - the interface is Up, all PMEs in the aggregation group      are upBeili                       Standards Track                    [Page 12]

RFC 5066                  EFMCu Interfaces MIB             November 2007   o  notAvailable - the interface is Down, all PMEs in the aggregation      group are Down, no handshake tones are detected by any PME   o  availableReduced - the interface is Up, a link fault is detected      at the receive direction by one or more PMEs in the aggregation      group, but at least one PME is Up   o  pmdLinkFault - a link fault is detected at the receive direction      by all PMEs in the aggregation group   As an EtherLike interface, every EFMCu port (an ifEntry representing   a consolidation of LLC, MAC, and PCS (sub)layers) SHALL return an   ifType of ethernetCsmacd(6).  While most of the MAU characteristics   are not applicable to the EFMCu ports (no auto-negotiation, false   carriers, or jabber), they SHALL return an appropriate ifMauType   (dot3MauType2BaseTL or dot3mauType10PassTS) in order to direct the   management software to look in the EFM-CU-MIB module for the desired   information.  For example, the information on the particular EFMCu   flavor that an EFMCu port is running is available from   efmCuOperSubType, defined in the EFM-CU-MIB module.   Since EFMCu PMEs are not EtherLike interfaces, they cannot be   instantiated as MAU interface objects.4.  MIB Structure4.1.  EFM Copper MIB Overview   The main management objects defined in the EFM-CU-MIB module are   split into 2 groups:   o  efmCuPort - containing objects for configuration, capabilities,      status, and notifications, common to all EFMCu PHYs.   o  efmCuPme - containing objects for configuration, capabilities,      status, and notifications of EFMCu PMEs.   The efmCuPme group in turn contains efmCuPme2B and efmCuPme10P   groups, which define PME profiles specific to 2BASE-TL and 10PASS-TS   PMEs, respectively, as well as PME-specific status information.4.2.  Interface Stack Capability MIB Overview   The IF-CAP-STACK-MIB module contains 2 tables:   o  ifCapStackTable - containing objects that define possible      relationships among the sub-layers of an interface with flexible      cross-connect (cross-connect capability).Beili                       Standards Track                    [Page 13]

RFC 5066                  EFMCu Interfaces MIB             November 2007   o  ifInvCapStackTable - an inverse of the ifCapstackTable.4.3.  PME Profiles   Since a managed node can have a large number of EFMCu PHYs,   provisioning every parameter on every EFMCu PHY may become   burdensome.  Moreover, most PMEs are provisioned identically with the   same set of parameters.  To simplify the provisioning process, the   EFM-CU-MIB module makes use of configuration profiles, similar to the   HDSL2-SHDSL-LINE-MIB and VDSL-LINE-EXT-MCM-MIB modules.  A profile is   a set of parameters, used either for configuration or representation   of a PME.  The same profile can be shared by multiple PME ports using   the same configuration.   The PME profiles are defined in the efmCuPme2BProfileTable and   efmCuPme10PProfileTable for 2BASE-TL and 10PASS-TS PMEs,   respectively.  There are 12 predefined standard profiles for 2BASE-TL   and 22 standard profiles for 10PASS-TS, defined in 802.3ah and   dedicated for rapid provisioning of EFMCu PHYs in most scenarios.  In   addition, the EFM-CU-MIB defines two additional predefined profiles   for "best-effort" provisioning of 2BASE-TL PMEs.  An ability to   define new configuration profiles is also provided to allow for EFMCu   deployment tailored to specific copper environments and spectral   regulations.   A specific configuration or administrative profile is assigned to a   specific PME via the efmCuPmeAdminProfile object.  If   efmCuPmeAdminProfile is zero, then the efmCuAdminProfile object of   the PCS port connected to the PME determines the configuration   profile (or a list of possible profiles) for that PME.  This   mechanism allows specifying a common profile for all PMEs connected   to the PCS port, with an ability to change individual PME profiles by   setting efmCuPmeAdminProfile object, which overwrites the profile set   by efmCuAdminProfile.   A current operating PME profile is pointed to by the   efmCuPmeOperProfile object.  Note that this profile entry can be   created automatically to reflect achieved parameters in adaptive (not   fixed) initialization.4.4.  Mapping of IEEE 802.3ah Managed Objects   This section contains the mapping between relevant managed objects   (attributes) defined in [802.3ah] Clause 30, and managed objects   defined in this document and in associated MIB modules, i.e., the IF-   MIB [RFC2863].Beili                       Standards Track                    [Page 14]

Security Considerations   There is a number of managed objects defined in the EFM-CU-MIB module   that have a MAX-ACCESS clause of read-write or read-create.  Most   objects are writeable only when the link is Down.  Writing to these   objects can have potentially disruptive effects on network operation,   for example:   o  Changing of efmCuPmeAdminSubType may lead to a potential locking      of the link, as peer PMEs of the same subtype cannot exchange      handshake messages.   o  Changing of efmCuPAFAdminState to enabled may lead to a potential      locking of the link, if the peer PHY does not support PAF.   o  Changing of efmCuPAFDiscoveryCode, before the discovery operation,      may lead to a wrongful discovery, for example, when two -O ports      are connected to the same multi-PME -R port and both -O ports have      the same Discovery register value.Beili                       Standards Track                    [Page 84]

RFC 5066                  EFMCu Interfaces MIB             November 2007   o  Changing PCS or PME configuration parameters (e.g., profile of a      PCS or PME via efmCuAdminProfile or efmCuPmeAdminProfile) may lead      to anything from link quality and rate degradation to a complete      link initialization failure, as ability of an EFMCu port to      support a particular configuration depends on the copper      environment.   o  Activation of a PME can cause a severe degradation of service for      another EFMCu PHY, whose PME(s) may be affected by the cross-talk      from the newly activated PME.   o  Removal of a PME from an operationally 'up' EFMCu port,      aggregating several PMEs, may cause port's rate degradation.   The user of the EFM-CU-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 the EFM-CU-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 particular, since EFMCu can be carried over   Unshielded Twisted Pair (UTP) voice-grade copper in a bundle with   other pairs belonging to another operator/customer, it is   theoretically possible to eavesdrop to an EFMCu transmission simply   by "listening" to a cross-talk from the EFMCu pairs, especially if   the parameters of the EFMCu link in question are known.   In such environments, it is important to control also 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 these MIB modules.   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 anBeili                       Standards Track                    [Page 85]
