Copyright Notice Copyright (C) The Internet Society (2003). All Rights Reserved. Abstract This document defines a portion of the Management Information Base (MIB) module for use with network management protocols in the Internet community. In particular, it describes objects used for managing the Line Code Specific parameters of Very High Speed Digital Subscriber Line (VDSL) interfaces using Multiple Carrier Modulation (MCM) Line Coding. It is an optional extension to the VDSL-LINE CORE MIB RFC XXXX [RFCXXXX] which handles the line code independent objects. Expires January 27, 2004 [Page 1]

Full Copyright Statement ...................................... 21 1. 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]. 2. Overview This document describes an SNMP MIB module for managing the line code dependent (Physical Medium Dependent) Layer of MCM VDSL Lines. These definitions are based upon the specifications for VDSL as defined in T1E1, ETSI, and ITU documentation [T1E1311, T1E1011, T1E1013, ETSI2701, ETSI2702, ITU9931, ITU9971]. Additionally the protocol-dependent (and line-code dependent) management framework for VDSL lines specified by DSLF has been taken into consideration [DSLFXXXXXX]. The MIB module is located in the MIB tree under MIB 2 transmission, as discussed in the MIB-2 Integration (RFC 2863 [RFC2863]) section of this document. 2.1 Relationship of this MIB Module to other MIB Modules The relationship of the VDSL Line MIB to other MIBS and in particular to the IF-MIB, as presented in RFC 2863 [RFC2863], is discussed in the VDSL-LINE CORE MIB RFC XXXX [RFCXXXX]. This section outlines the Expires January 27, 2004 [Page 2]

It contains the following tables: - vdslLineMCMConfProfileTable - vdslLineMCMConfProfileTxBandTable - vdslLineMCMConfProfileRxBandTable - vdslLineMCMConfProfileTxPSDTable - vdslLineMCMConfProfileMaxTxPSDTable - vdslLineMCMConfProfileMaxRxPSDTable Either none, some or all of the objects in this group MAY be implemented for MCM VDSL lines. Figure 1, below, displays the relationship of the tables in the vdslMCMGroup to the vdslGroup and to the ifEntry: Expires January 27, 2004 [Page 3]

The existence of an entry in any of the tables of the vdslMCMGroup is optional. Either none, some or all of the vdslMCMGroup tables MAY be implemented for a particular VDSL line entity using MCM line coding. 2.4 Persistence All read-write and read-create objects defined in this MIB module SHOULD be stored persistently. Following is an exhaustive list of these persistent objects: vdslMCMConfProfileTxWindowLength vdslMCMConfProfileRowStatus vdslMCMConfProfileTxBandNumber vdslMCMConfProfileTxBandStart vdslMCMConfProfileTxBandStop vdslMCMConfProfileTxBandRowStatus vdslMCMConfProfileRxBandStart vdslMCMConfProfileRxBandStop vdslMCMConfProfileRxBandRowStatus vdslMCMConfProfileTxPSDTone vdslMCMConfProfileTxPSDPSD vdslMCMConfProfileTxPSDRowStatus vdslMCMConfProfileMaxTxPSDTone vdslMCMConfProfileMaxTxPSDPSD vdslMCMConfProfileMaxTxPSDRowStatus vdslMCMConfProfileMaxRxPSDTone vdslMCMConfProfileMaxRxPSDPSD vdslMCMConfProfileMaxRxPSDRowStatus It SHOULD also be noted that interface indices in this MIB are maintained persistently. VACM data relating to these SHOULD be stored persistently as well [RFC2575]. Expires January 27, 2004 [Page 4]

Security Considerations There are a number of management objects defined in this MIB that have 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. Expires January 27, 2004 [Page 19]
INTERNET-DRAFT VDSL-LINE EXTENSION MCM MIB July 2003 VDSL layer connectivity from the Vtur will permit the subscriber to manipulate both the VDSL link directly and the VDSL embedded operations channel (EOC) for their own loop. For example, unchecked or unfiltered fluctuations initiated by the subscriber could generate sufficient notifications to potentially overwhelm either the management interface to the network or the element manager. For this reason, there are a number of managed objects in this MIB that may contain sensitive information. It is thus important to control even GET access to these objects and possibly to even encrypt the values of these objects when sending them over the network via SNMP. Not all versions of SNMP provide features for such a secure environment. Further, notifications generated by agents implementing this MIB will contain the above threshold information. 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) objects which utilize the textual conventions defined 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 a MIB module which utilizes the textual conventions defined in 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. 9.
