Abstract The purpose of this memo is to define the Management Information Base (MIB) for supporting Classical IP and ARP over ATM as specified in Classical IP and ARP over ATM, refer to reference [3]. Support of an ATM interface by an IP layer will require implementation of objects from several Managed Information Bases (MIBs) as well as their enhancement in order to enable usage of ATM transports. It is the intent of this MIB to fully adhere to all prerequisite MIBs unless explicitly stated. Deviations will be documented in corresponding conformance statements.

Introduction This document is a product of the Internetworking Over NBMA Working Group. Its purpose is to define a MIB module for extending the traditional MIBs supported by a TCP/IP implementation to support Classical IP and ARP over ATM. Many MIB related RFCs and Internet Drafts have been considered in the development of this document. The ones that are considered central to the extensions defined by this document are: o RFC 2011 - SNMPv2 Management Information Base for the Internet Protocol using SMIv2 [10]. The IP over ATM MIB provides extensions to the IP Group for handling IP over ATM flows. A basic understanding of the IP Group is essential for understanding this document. o RFC 1573 - Interfaces Group Evolution [2]. This document is important since it provides several very useful Expires August 1997 [Page 2] Greene et al. IP and ARP over ATM MIB 19 February 1997 enhancements over the interface group defined in RFC 1213 that aid in handling ATM related interfaces. o RFC 1695 - Definitions of Managed Objects for ATM Management [4]. Support of this MIB is required for implementing the layers between AAL5 and ATM. The contents of this MIB will not explicitly be address here. RFC 1695 provides a basis for managing ATM interface layering and management of: - ATM Switched Virtual Connections (SVCs) - ATM Permanent Virtual Connections (PVCs) The ATM Forum UNI ILMI MIB is specified by the ATM Forum in various versions of the UNI specification. The ILMI MIBs being defined are not supported via SNMP agents but via SNMP requests sent over an ATM network to an ATM entity encapsulated in an AAL5 header. Support of the ILMI MIB(s) is considered out of the scope of this document. 2. The SNMPv2 Network Management Framework The SNMP Network Management Framework presently consists of three major components. They are: o the SMI, described in RFC 1902 [1], - the mechanisms used for describing and naming objects for the purpose of management. o the MIB-II, STD 17, RFC 1213 [5], - the core set of managed objects for the Internet suite of protocols. o the protocol, RFC 1157 [9] and/or RFC 1905 [7] - the protocol for accessing managed information. Textual conventions are defined in RFC 1903 [6], and conformance statements are defined in RFC 1904 [8]. The Framework permits new objects to be defined for the purpose of experimentation and evaluation. This memo specifies a MIB module that is compliant to the SNMPv2 SMI. A semantically identical MIB conforming to the SNMPv1 SMI can be produced through the appropriate translation. Expires August 1997 [Page 3] Greene et al. IP and ARP over ATM MIB 19 February 1997 2.1. Object Definitions Managed objects are accessed via a virtual information store, termed the Management Information Base or MIB. Objects in the MIB are defined using the subset of Abstract Syntax Notation One (ASN.1) defined in the SMI. In particular, each object object type is named by an OBJECT IDENTIFIER, an administratively assigned name. The object type together with an object instance serves to uniquely identify a specific instantiation of the object. For human convenience, we often use a textual string, termed the descriptor, to refer to the object type. 3. Structure of the MIB The Classical ARP and IP over ATM MIB structure is split into three components: o Basic Support MIB Definitions o Client Supported MIB Definitions o ATMARP Server MIB Definitions All IP and ARP over ATM entities, both clients and ATMARP servers, are required to support the MIB definitions in the Basic Support MIB Definitions section. Clients need to additionally support the MIB definitions outlined in the Client specific section and ATMARP Servers must additionally support the ATMARP Server specific MIB definitions. Implementation of the Definitions of Managed Objects for ATM Management [4] defines the modeling of the various layers within an ATM Interface. This modeling is assumed as a prerequisite for the IP- ATM MIB. The IP-ATM MIB makes no assumptions on how this layering is actually implemented within a system. Several of the MIB tables defined by the IP-ATM MIB, like the base TCP/IP MIBs, requires that an ifIndex exist that points to an ATM Interface. Refer to the Definitions of Managed Objects for ATM Management (RFC 1695) for the definition of an ATM Interface interface layering. The use of an IP over ATM Virtual Interface layer is not explicitly required by the IP-ATM MIB. The use of virtual layers above an RFC1695 defined interface layer is not absolutely necessary for modeling the attachment of IP to an ATM network. The IP-ATM MIB uses a generic ifIndex that must related to a ATM Physical Interface in its MIB definitions. It up to the implementers of this MIB to determine their own ATM interface layering (assuming compliance with RFC 1573 and RFC 1695). The IANA ifType propVirtual was created for this purpose and is used in RFC 1695. Expires August 1997 [Page 4] Greene et al. IP and ARP over ATM MIB 19 February 1997 3.1. Basic Support MIB Definitions Basic support that must be implemented by both Clients and ATMARP Servers consist of: o ATM Logical IP Subnet (LIS) Table o ATM Logical IP IF Mapping Table o ATMARP Remote Server Table o ATM VC Table o Notifications 3.1.1. ATM Logical IP Subnet (LIS) Table The ATM Logical IP Subnet (LIS) Table defines the subnets that this system is a member of for purposes of reaching destinations over a ATM transport. The LIS table is indexed by the subnet address (ipAtmLisSubnetAddr) and not ifIndex. The ipAtmLisIfMappingTable described in the next section provides the mapping between Logical IP Subnets and the interface layer. It is possible that the same LIS can be reached via different ATM physical interfaces. The ipAddrTable and the ipAtmClientTable provides the mapping from a local IP address to a ATM physical interface. One or more ipAddrTable entries can point to the same ipAtmLisEntry. An ipAddrEntry's ipAdEntAddr ANDed with its ipAdEntNetMask should equal an ipAtmLisEntry's ipAtmLisSubnetAddr. Given that a interface can be multi-homed each local IP address associated with an interface requires an entry in the ipAddrTable. Each ipAddrTable entry for a local IP address associated with a ATM physical interface should map to an entry in the ipAtmLisTable. The bulk of the objects in a ipAtmLisEntry exists to control ATMARP for a particular LIS: ipAtmLisInactivityTimer ipAtmLisMinHoldingTime ipAtmLisQDepth ipAtmLisMaxCalls ipAtmLisCacheEntryAge ipAtmLisRetries ipAtmLisTimeout An ipAtmLisMaxCalls defines the maximum number of VCs that can be established simultaneously per LIS. An ipAtmLisDefaultPeakCellRate defines the best effort default peak cell rate in both the forward and backwards direction when establishing a VCCs. Expires August 1997 [Page 5] Greene et al. IP and ARP over ATM MIB 19 February 1997 The ipAddrTable's ipAdEntReasmMaxSize is the "The size of the largest IP datagram which this entity can re-assemble from incoming IP fragmented datagrams received on this interface" and is different from the ipAtmLisTable's ipAtmLisDefaultMtu with is the default MTU used within an LIS. Note that this is the default MTU used within the LIS represented by this entry. Note that this is the default MTU not the actual which is represented as ipAtmVcNegotiatedMtu in the ipAtmVcTable. The ipAtmLisRowStatus object enables entries in the ipAtmLisTable to be created or deleted via SNMP. Creation of an ipAtmLisTable entry results in the adding of a corresponding ipAddrTable entry and a ipAtmLisIfMappingTable entry. Creation of multiple ipAddrTable entries and ipAtmLisIfMappingTable entries for the same LIS is not addressed by this document. When ipAtmLisRowStatus is changed from 'active(1)' to 'notInService(2)' or from 'active(1)' to 'destroy(6)', this has the side-effect of removing all entries from the ipNetToMediaTable that are associated with this LIS (in other words, it flushes the entity's ATMARP cache). It also removes the ipAtmVcTable entries that were associated with those ipNetToMediaTable entries. Destroying the row removes the corresponding entries in the ipAtmArpSrvrTable, ipAtmArpClientTable, ipAtmLisIfMappingTable and the ipAtmArpRemoteSrvrTable. 3.1.2. ATM Logical IP IF Mapping Table The ipAtmLisIfMappingTable maps a LIS to all ATM physical interfaces that it is configured to be supported from. Each entry in the ipAtmLisIfMappingTable should map to a ipAddrTable entry. It is also possible for a system, most commonly a switch, to have multiple LISes associated with the same ATM physical interface. 3.1.3. ATMARP Remote Server Table Entries in the ipAtmArpRemoteSrvrTable exists to locally configure the remote ATMARP Servers that exist on a per LIS basis. Classic2 requires that at least one ATMARP server be configured per LIS where SVC traffic is intended. PVC usage doesn't require use of ATMARP. No ipAtmArpRemoteSrvrTable entries should be configured for a LIS where only PVCs will be used. An entry in the ipAtmArpRemoteSrvrTable is indexed by the subnet address of the LIS, ipAtmLisSubnetAddr, and the ATM address of the remote ATMARP server, ipAtmArpRemoteSrvrAddr. If a PVC is intended to be used to communicate with a remote ATMARP server then ipAtmArpRemoteSrvrVpi and ipAtmArpRemoteSrvrVci need to be set when the entry is created. Otherwise they will be filled in when a SVC is established with the remote ATMARP server. Expires August 1997 [Page 6] Greene et al. IP and ARP over ATM MIB 19 February 1997 3.1.4. ATM VC Table A entry in the ipAtmVcTable should have at least one corresponding ipNetToMediaTable entry. Both tables use the ipNetToMediaTable's indexes ipNetToMediaIfIndex and ipNetToMediaNetAddress. The ipAtmVcTable has the additional indexes ipAtmVcVpi and ipAtmVcVci. A ipAtmVcEntry exists for every VC per ATM physical interface per destination IP address. Refer to the following diagram that illustrates the relationship between ipAtmVcTable and the ipNetToMediaTable: ipAtmVcTable ipNetToMediatable ------------------------------- ---------------------------- ipNetToMediaIfIndex ipNetToMediaIfIndex ipNetToMediaNetAddress ipNetToMediaNetAddress ipAtmVcVpi ipAtmVcVci ipAtmVcType ipNetToMediaPhysAddress ipAtmVcNegotiatedEncapsType ipAtmVcNegotiatedMtu ipAtmVcRowStatus ipNetToMediaType ------------------------------- ---------------------------- ipAtmVcType indicates if the entry is for a SVC or PVC. A ipAtmVcEntry corresponding to a PVC would have to have its ipAtmVcVpi and ipAtmVcVci configured. The associating ipNetToMediaTable entry would have its ipNetToMediaType set to static(4). ipNetToMediaTable entries created during the ATMARP processing have a ipNetToMediaType of dynamic(3). It is possible to locally configure a ipNetToMediaTable entry and a ipAtmVcTable entry for a SVC without using ATMARP. For this situation the ipNetToMediaType would be static(4). 3.1.5. Notifications Both ATM clients and ATMARP Servers must support generation of a ipAtmMtuExceed notification. 3.2. Client Supported MIB Definitions The ATMARP Client Table is the only additional MIB table that a client must implement. Expires August 1997 [Page 7] Greene et al. IP and ARP over ATM MIB 19 February 1997 3.2.1. ATMARP Client Table A entry in the ipAtmArpClientTable should have a corresponding ipAddrTable entry where both are indexed by the same ipAdEntAddr. Refer to the following diagram that illustrates the relationship between ipAtmArpClientTable and ipAddrTable entries: ipAtmArpClientTable ipAddrTable ------------------------------------ ------------------------ ipAdEntAddr ipAdEntAddr ipAdEntNetMask ipAdEntIfIndex ipAtmArpClientAtmAddr ipAtmArpClientSrvrInUse ipAtmArpClientInArpReqsIn ipAtmArpClientInArpReqsOut ipAtmArpClientInArpRepliesIn ipAtmArpClientInArpRepliesOut ipAtmArpClientInArpInvalidReqsIn ipAtmArpClientInArpInvalidReqsOut ipAtmArpClientArpReqsOut ipAtmArpClientArpRepliesIn ipAtmArpClientArpNaksIn ipAtmArpClientArpOpUnknown ipAtmArpClientArpSrvrNoResp ipAtmArpClientRowStatus ipAdEntBcastAddr ipAdEntReasmMaxSize ------------------------------------ ------------------------ Both tables use the same index, ipAdEntAddr. The ipAddrTable's ipAdEntNetMask when ANDed with its ipAdEntAddr yield the subnet of the LIS which indexes the ipAtmLisTable. The ipAddrTable's ipAdEntIfIndex points to the a physical interface ifTable entry. The attachment point for IP into an ATM network is via an ATM interface's ifIndex. This ifIndex is contained in an ipAddrTable entry. ipAtmArpClientAtmAddr is the local ATM address associated with the corresponding ATM ifTable entry. ipAtmArpClientSrvrInUse is the ATM address of the ATMARP server being used for aparticular client. If SVCs are not being used then the value of this object is 0. It is sometimes possible for a system to have multiple IP addresses configured within the same IP subnet. The indexing of this table would seem to preclude that, however, it is possible to have additional entries in the ipAddrTable with the same ifIndex and with the same subnet address. The mechanism for adding these entries to the ipAddrTable (which is read-only) is beyond the scope of this document. Expires August 1997 [Page 8] Greene et al. IP and ARP over ATM MIB 19 February 1997 3.3. Server Supported Objects ATMARP servers must support: o ATMARP Server Table o Notifications as defined in the following sections. This table exists only on a system where at least one ATMARP server is present. 3.3.1. ATMARP Server Table This table defines the list of ATMARP servers within a LIS. Each entry of the table defines each ATMARP server's ATM address, the LIS it is a member of, and various InATMARP and ATMARP statistics. An entry in this table provides information about an ATMARP server within a LIS and is indexed by ipAdEntAddr and the ipAtmArpSrvrAddr (ATM address of the ATMARP server). Entries may be created by a management application using the ipAtmArpSrvrRowStatus object. In an SVC environment, the ipAtmArpSrvrAddr must be specified before the entry's ipAtmArpSrvrRowStatus can be set to 'active(1)'. In a PVC environment, the ipAtmArpSrvrVpi and ipAtmArpSrvrVci values must also be specified; these values are the VPI/VCI of a PVC that was established using some mechanism outside the scope of this MIB module (generally RFC1695, the AToM MIB). Entries in this table may also be created by the system and not by a management application, for example as a result of ILMI. Entries in this table may be deleted by setting the ipAtmArpSrvrRowStatus object to 'destroy(6)'. This includes entries that were added by the system and not by a management application. 3.3.2. Notifications An ATMARP Server must support the following notifications: o ipAtmDuplicateIpAddress o ipAtmLisCreate o ipAtmLisDelete Generation of ipAtmLisCreate and ipAtmLisDelete notifications is controlled by the ipAtmLisTrapEnable object. These notifications indicated when a ipAtmLisEntry is either created or deleted. The purpose of these notifications is to enable Network Management Expires August 1997 [Page 9] Greene et al. IP and ARP over ATM MIB 19 February 1997 Applications to dynamically discover the existence of ATMARP Server LIS participation in order to eventually determine LIS composition via subsequent SNMP queries. It is permissible for a ATM client only system to support the ipAtmLisTrapEnable object and generate ipAtmLisCreate and ipAtmLisDelete notifications. 4.
