Introduction The Multi-pair bonding using time-division inverse multiplexing (TDIM), a.k.a. G.Bond/TDIM, is specified in ITU-T G.998.3 recommendation [G.998.3], which defines a method for bonding (or aggregating) of multiple xDSL lines (or individual bearer channels in multiple xDSL lines) into a single bi-directional logical link, carrying a mix of various traffic streams, e.g. Ethernet, Asynchronous Transfer Mode (ATM), Time-Division Multiplexing (TDM). The MIB module, defined in this document, provides G.Bond/ TDIM-specific objects for the management of G.998.3 bonded interfaces, extending the common bonding objects specified in GBOND- MIB [I-D.ietf-adslmib-gbond-mib] module. 2. The Internet-Standard Management Framework For a detailed overview of the documents that describe the current Internet-Standard Management Framework, please refer to section 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 a MIB module that is compliant to the SMIv2, which is described in STD 58, RFC 2578 [RFC2578], STD 58, RFC 2579 [RFC2579] and STD 58, RFC 2580 [RFC2580]. The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in RFC 2119 [RFC2119]. 3. The Broadband Forum Management Framework for xDSL Bonding This document makes use of the Broadband Forum technical report Management Framework for xDSL Bonding [TR-159], defining a management model and a hierarchy of management objects for the bonded xDSL interfaces. 4. Relationship 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 following MIB modules are discussed: Interfaces Group MIB (IF-MIB) and G.Bond MIB (GBOND-MIB). Beili Expires August 12, 2012 [Page 3] Internet-Draft G.Bond/TDIM MIB February 2012 4.1. Relationship to Interfaces Group MIB module A G.Bond/TDIM port is a private case of a Bonded multi-pair xDSL interface and as such is managed using generic interface management objects defined in the IF-MIB [RFC2863]. In particular an interface index (ifIndex) is used to index instances of G.Bond/TDIM ports, as well as xDSL lines/channels, in a managed system. 4.2. Relationship to G.Bond MIB module GBOND-MIB [I-D.ietf-adslmib-gbond-mib] module defines management objects common for all Bonded multi-pair xDSL interfaces. In particular it describes the bonding management, bonded port and channel configuration, initialization sequence etc. Both GBOND-MIB and GBOND-TDIM-MIB modules are REQUIRED to manage a G.Bond/TDIM port. 5. MIB Structure 5.1. Overview All management objects defined in the GBOND-TDIM-MIB module are contained in a single group gBondTdimPort. This group is further split into 6 sub-groups, structured as recommended by RFC 4181 [RFC4181]: o gBondTdimPortNotifications - containing notifications (TDIM Service Down/Up). o gBondTdimPortConfTable - containing objects for configuration of a G.Bond/TDIM port. o gBondTdimPortCapTable - containing objects reflecting capability of a G.Bond/TDIM port. o gBondTdimPortStatTable - containing objects providing overall status information of a G.Bond/TDIM port, complementing the generic status information from the ifTable of IF-MIB and gBondPortStatFltStatus of GBOND-MIB. o gBondTdimSvcTable - containing objects for configuration and status of the services in a G.Bond/TDIM port. o gBondTdimPM - containing objects for an OPTIONAL Historical Performance Monitoring (PM) of a G.Bond/TDIM port. Beili Expires August 12, 2012 [Page 4] Internet-Draft G.Bond/TDIM MIB February 2012 5.2. Link Protection Configuration G.Bond/TDIM specification allows an optional Forward Error Correction (FEC) and Interleaver block, which, if supported and enabled, provides a degree of protection against micro-interruptions, alien noise, and even individual Bonding Channel Entity (BCE) failures, a.k.a. cut-line protection. Management objects in the gBondTdimPortConfTable can be used to configure and query the FEC and Interleaver function of the G.Bond/ TDIM port. 5.3. Service Configuration Unlike the other two xDSL Multi-Pair Bonding schemes (G.Bond/ATM and G.Bond/Ethernet), which send the information required for reassembly of the fragmented data along with the data, G.Bond/TDIM is a synchronous scheme, requiring both ends to know the data distribution tables before any actual data transfer can happen. Management objects in the gBondTdimPortConfTable (gBondTdimPortConfAdminServices), gBondTdimSvcTable and gBondTdimOperSvcTable can be used to configure and query the configuration of services transported via the G.Bond/TDIM link. The services may be configured independently of the link state (i.e. in- and out-of-service), as G.998.3 communicates changes in the service configuration via specific Bonding Communication Channel (BCC) messages, switching both ends of the link to the new configuration synchronously. There can be up to 60 active services defined on a G.Bond/TDIM link. This MIB module provides an ability to define up to 255 services via the gBondTdimSvcTable, with each row representing a possible service, and then set the actual service configuration using the gBondTdimPortConfAdminServices object (a byte-vector of service indices), listing the active services in the order of their position in the G.Bond/TDIM frame. This design allows one to easily modify service drop priority, which directly corresponds to the service position. The actual list of services is provided via the read-only gBondTdimOperSvcTable, where each entry's index corresponds to the service position, starting from index 1 for the first entry, 2 for the second entry etc., providing an easy service navigation for a management application using GET-NEXT (instead of counting bytes in the gBondTdimPortConfAdminServices object). The service configuration can only be changed on a Bonding Beili Expires August 12, 2012 [Page 5] Internet-Draft G.Bond/TDIM MIB February 2012 Transmission Unit at the Central Office (BTU-C). When configuring the services, please bear in mind that the sum of all the services' bandwidth SHOULD be less or equal to the target data rate of the bonded link. Note that G.Bond/TDIM links are symmetrical, i.e. their upstream data rate equals to the downstream data rate. 5.3.1. Management of TDM Services and service drop priority during bandwidth degradation G.Bond/TDIM protocol provides an ability to map TDM services into the TDIM bonded link directly, without any additional overhead. It addresses only structure-agnostic TDM transport, disregarding any structure that may be imposed on these streams, in particular the structure imposed by the standard TDM framing [G.704]. During bandwidth degradation services with a lower priority are impaired or dropped first. Synchronous services (fractional DS1/E1, clear channel E1/T1, T3/E3, clock) positioned in the beginning of the G.Bond/TDIM frame, have higher priority than asynchronous services (Ethernet, ATM, GFP encapsulated), positioned farther away. Within the services of the same type, those with lower position (index) have higher priority. 5.3.2. Service Notifications This MIB module provides specific Up/Down notifications (gBondTdimSvcUp/gBondTdimSvcDown) for each of the configured services. During bandwidth degradation a number of services may be suspended (dropped) simultaneously, according to their drop priority (position in the service list). Please note that it is possible for a higher priority service to be dropped before a lower priority one. For example, suppose there are two services configured on a 2 Mbps G.Bond/TDIM link: a T1 service (gBondTdimSvcType with a value of ds1, with a bandwidth requirement of 1.5 Mbps) and an Ethernet service with a size of 0.5 Mbps. When the actual link bandwidth is reduced to 1.4 Mbps, the T1 service with a gBondTdimOperSvcPosition value of 1 would be dropped, while the Ethernet service with a gBondTdimPerSvcPosition value of 2 would remain up. Notifications SHOULD be rate-limited (throttled) such that there is an implementation-specific gap between the generation of consecutive notifications of the same event. This mechanism prevents notification flooding in case gBondTdimServiceOperState oscillates between Up and Down states. When notifications are rate-limited, they are dropped and not queued for sending at a future time. This is intended to be a general rate-limiting statement for notifications Beili Expires August 12, 2012 [Page 6] Internet-Draft G.Bond/TDIM MIB February 2012 that otherwise have no explicit rate-limiting assertions in this document. 5.4. Performance Monitoring The OPTIONAL performance monitoring counters, thresholds and history buckets (interval-counters), similar to those defined in [TR-159] are implemented using the textual conventions defined in the HC-PerfHist- TC-MIB [RFC3705]. The HC-PerfHist-TC-MIB defines 64-bit versions of the textual conventions found in PerfHist-TC-MIB [RFC3593]. The agent SHOULD align the beginning of each interval to a fifteen minute boundary of a wall clock. Likewise, the beginning of each one day intervals SHOULD be aligned with the start of a day. Counters are not reset when a G.Bond TDIM port is reinitialized, but rather only when the agent is reset or reinitialized. Note that the accumulation of certain performance events for a monitored entity is inhibited (counting stops) during periods of service unavailability on that entity. The DESCRIPTION clause of performance monitoring counters in this MIB module specifies which of the counters are inhibited during periods of service unavailability. 5.5. Mapping of Broadband Forum TR-159 and ITU-T G.998.3 Managed Objects This section contains the mapping between relevant managed objects (attributes) defined in [TR-159] and managed objects defined in this document. Note that all management objects defined in [G.998.3] have corresponding objects in [TR-159].

However, since their definition is identical to the definition of gBondPortPm* objects of the GBOND-MIB module, we can map gBondTdimPortPm* and gBondTdimSvcPm* to the relevant aGroupPerf* attributes of TR-159 and use the term 'partial mapping' to denote the fact that this mapping is not one-to-one. 6.

Security Considerations There is a number of managed objects defined in this MIB module with a MAX-ACCESS clause of read-write and/or read-create. Such objects may be considered sensitive or vulnerable in some network environments. The support for SET operations in a non-secure environment without proper protection can have a negative effect on network operations. These are the tables and objects and their sensitivity/vulnerability: o Changing of gBondTdimPortConfAdminServices object may lead to a potential service disruption, by changing a particular service' position (therefore changing its drop priority) or even removing the service from the link altogether. o Changing of gBondTdimSvcTable configuration parameters (e.g. gBondTdimSvcType or gBondTdimSvcSize) may lead to a potential service impairment, for example a TDM service would be dropped if there is not enough actual bandwidth on the bonded link to support this service. o Changing of gBondTdimPortConfTable configuration parameters (e.g. gBondTdimPortConfFecAdminState) may lead to anything from link quality and rate degradation to a complete link initialization failure. Some of the readable objects in this MIB module (i.e., those with MAX-ACCESS other than not-accessible) may be considered sensitive or vulnerable in some network environments since, collectively, they provide information about the performance of network interfaces and can reveal some aspects of their configuration. In particular, since a bonded xDSL port can be comprised of multiple Unshielded Twisted Pair (UTP) voice grade copper, located in the same bundle with other pairs belonging to another operator/customer, it is theoretically possible to eavesdrop to a G.Bond transmission, simply Beili Expires August 12, 2012 [Page 50] Internet-Draft G.Bond/TDIM MIB February 2012 by "listening" to a cross-talk from the bonded pairs, especially if the operating parameters of the G.Bond link in question are known. It is thus important to control even GET and/or NOTIFY access to these objects and possibly even encrypt the values of these objects when sending them over the network via SNMP. These are the tables and objects and their sensitivity/vulnerability: o gBondTdimPortStatFecOperState in gBondTdimPortStatTable indicate whether the FEC function is enabled, which may aid in deciphering of the G.Bond/TDIM transmissions. o gBondTdimOperSvcTable provide current operational service configuration, which may aid in deciphering of the G.Bond/TDIM transmissions. SNMP versions prior to SNMPv3 did not include adequate security. Even if the network itself is secure (for example by using IPSec), 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. Implementations MUST provide the security features described by the SNMPv3 framework (see [RFC3410]), including full support for authentication and privacy via the User-based Security Model (USM) [RFC3414] with the AES cipher algorithm [RFC3826]. Implementations MAY also provide support for the Transport Security Model (TSM) [RFC5591] in combination with a secure transport such as SSH [RFC5592] or TLS/DTLS [RFC6353]. 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. 8.
