Expires April 1996 [Page 1] Internet Draft DLSw MIB Using SNMPv2 ((951009 -- v6.0)) October 1995 Abstract This specification defines an extension to the Management Information Base (MIB) for use with SNMP-based network management. In particular, it defines objects for configuring, monitoring, and controlling Data Link Switches (DLSw) [1]. This memo specifies a MIB module in a manner that is both compliant to the SNMPv2 SMI [2], and semantically identical to the SNMPv1 definitions [3]. 1.0 Change Log This section tracks changes made to the revisions of this document. It will be deleted when the document is published as a RFC. 10/09/95 (version 0.6 - changes just preceding and at AIW8) 1. Eliminated enumerated values of zero for dlswCircuitPriority and dlswCircuitDiscReasonRemote. 2. Added objects dlswDirMacCacheNextIndex and dlswDirNBCacheNextIndex, to make it possible for a management station to add configured cache entries. Note that putting these objects in a logical place required changes to the object id's of several other objects. 3. Modified the description of dlswTConnConfigLastModifyTime to exclude dlswTConnConfigOpens from being considered as a change requiring an update to ...LastModifyTime. 4. Changed the description of dlswTConnConfigAdvertiseMacNB to clarify which control vectors should be sent for each object value. 5. Created textual convention for non-canonical format MAC addresses, including making a consistent rule that a zero length should be returned for unavailable MAC addresses. 6. Corrected DEFVALs of null instance pointers so they would compile (they had been commented out). 7. Made the following object name changes: o dlswSdlcLsLocalBlockNum -> dlswSdlcLsLocalIdBlock (also clarified this is in fact configurable) o Objects in node group -> dlswNode...... o Circuit statistics objects -> dlswCircuitStat..... 8. Changed the MIB basing to the IETF-assigned experimental tree location. 9. Corrected the conformance statements to match the current object names and groups. 06/30/95 (version 0.5) 1. Changes adopted by the AIW DLSw MIB RIGLET / IETF DLSw MIB Working Group during AIW 7 (May 1-3, 1995) in San Jose. Major changes include: o Added QLLC as a DLC type. Expires April 1996 [Page 2] Internet Draft DLSw MIB Using SNMPv2 ((951009 -- v6.0)) October 1995 o Fixed up DEFVALs for LF size objects and SAP list objects. Expanded range for all pacing objects. o Moved all pacing objects (global and TC-level) to the circuit table. o Introduced TCP-specific TConnConfig and TConnOper tables, moved some objects there from existing tables. o Removed mask concept from TConnConfig, added ability to exclude specified partners. o Changed rule about backward reference from TConnOper to TConnConfig. o Reworked disconnect reason codes for TCs and Circuits. o For MAC address and NB name cache, allowed local configured entries not to be advertised in capabilities exchange. o Added object for remote circuit disconnect reason 2. Numerous editorial improvements and clarifications to descriptions. Some are marked with to-be-deleted comments to make sure everyone is ok with the change. 3. Added group reference to TConnConfig as an escape for those who would like to do masks or some other vendor-specific grouping scheme. This adds no complexity for those who do not want a group concept. 4. Deleted Initial window objects from the circuit table, and added only the send window back to TConnOper as saved from capabilities exchange. Also added TCP connections from capability exchange. 5. Removed the directory search function. We can add it back if someone feels it should be in the standard MIB. 6. Assigned numbers and corrected dozens of small errors to get it to compile successfully (I left 1 warning) using smicng. 04/24/95 (version 0.4) 1. The changes adopted by the AIW DLSw MIB RIGLET and IETF DLSw MIB Working Group. 01/20/95 (version 0.3) 1. Changes are based on the review during IETF San Jose Meeting on 12/06/94. Most part of Node group and Circuit group were reviewed. Major changes include: o dlswName and dlswDescr were removed. o dlswSnaSupport and dlswNBSupport were removed. o dlswFlowCntlSupport was replaced with dlswXBusySupport and dlswPacingSupport which specify the product's code capabilities of supporting ENTER_BUSY/EXIT_BUSY messages and supporting Fixed/Adaptive flow control scheme, respectively. In each object, the capabilities of send and receive modes are separately enumerated. o dlswAdminFlowCntlMode and dlswOperFlowCntlMode were removed. o New enumeration, xBusy, was added to dlswTConnFlowCntlMode. o Text of dlswAdminVirtualSegment which describing when the value takes effect was removed. Expires April 1996 [Page 3] Internet Draft DLSw MIB Using SNMPv2 ((951009 -- v6.0)) October 1995 o The name of dlswAdminVirtualSegmentMTU was changed to dlswAdminVirtualSegmentLFSize. Eight enumeration values were defined which are based on the Largest Frame (LF) Base Values specified in ANSI/IEEE Std 802.1D Annexes 1993 edition. o The description of dlswAdminStatus was written to define the meaning of active and inactive operations. o The range of the size of pacing window related object was set to (0..65). o A trap-enable object for each type of notification was added to control its emission. Those are: dlswTConnEnableStatusTraps, dlswTConnEnableRejectionTraps, dlswTConnEnableProtVltnTraps, and dlswEnableOutOfResourceTraps. o DLSw partner configuration section was modified. Now SAP list and initial window size are the only information that are configurable on per DLSw partner basis. o dlswTransportTcpReadPortNumber was added. o dlswTConnTcpOperConnTable was added to identify each TCP connection with local and remote port numbers. o The state that causes an instance in the dlswCircuitTable being substantiated was clarified. o Now End Station 1 (S1) of the dlswCircuitTable is always representing an end station that is locally attached. Thus, dlswCircuitS1Location, dlswCircuitS1TDomain and dlswCircuitS1TAddress were removed. o All flow control statistics related objects in the dlswCircuitTable were removed. 8 flow control objects were added to dlswTConnTable. o dlswCircuitStateDownTime, dlswCircuitS1SenseCode, and dlswCircuitS2SenseCode were removed. dlswCircuitSenseCode was added with an enumerated list. o Now the index to dlswSdlcLsTable is dlswSdlcLsLocalMac and dlswSdlcLsLocalSap. 2. Other changes: 11/29/94 (version 0.2) 1. Changes are based on the conference call review on 11/8/94. Directory group (administrative, statistics, reachability cache, and directory search initiation) was reviewed. Circuit group was only briefly discussed. Major changes include: o Explorer message counters, and outstanding exploring message information were removed. o Technique for NMS to initiate directory search and retrieve the result was clarified. o Indices of reachability cache tables were changed. o A number of types and states of cache entries were added. o Circuit event log table was removed. Last sense codes from the origin and target DLSw partners were moved to dlswCiruitTable. 2. Other changes: o dlswCirEstabTable was renamed to dlswCircuitTable. Expires April 1996 [Page 4] Internet Draft DLSw MIB Using SNMPv2 ((951009 -- v6.0)) October 1995 o The index of dlswCirEstabTable was changed to end station 1 (S1) and end station 2 (S2) MAC-SAP pairs. 11/01/94 (version 0.1) - Initial Draft 1. The initial draft was based on the proposal of David Chen and Peter Gayek. 2. The following ideas in the Wellfleet DLSw MIB were identified and incorporated: o a table to show/control what interface DLSw is active on o virtual ring MTU size o TCP maximum segment size (MSS) 3. The structure and objects of dlswNode and dlswTConn were agreed in AIW6 (10/12-10/13/94). 4. Other contributions: o Object and operations of how to apply changes in CapEx control vectors to runtime CapEx messages. (Alan Sciacca) o Script about the correct usage of counters for accounting purposes. (Alan Sciacca) o TCP transport specific objects. (Peter Gayek) o Definition of data and control traffic statistcs. (Peter Gayek) 2.0 Introduction 3.0 The SNMPv2 Network Management Framework The SNMPv2 Network Management Framework consists of four major components. They are: o RFC 1442 [2] which defines the SMI, the mechanisms used for describing and naming objects for the purpose of management. o STD 17, RFC 1213 [4] defines MIB-II, the core set of managed objects for the Internet suite of protocols. o RFC 1445 [5] which defines the administrative and other architectural aspects of the framework. o RFC 1448 [6] which defines the protocol used for network access to managed objects. The Framework permits new objects to be defined for the purpose of experimentation and evaluation. 3.1 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 Expires April 1996 [Page 5] Internet Draft DLSw MIB Using SNMPv2 ((951009 -- v6.0)) October 1995 SMI. In particular, each 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. 4.0 Overview This memo identifies the set of objects for configuring, monitoring, and controlling Data Link Switches. 4.1 Relation to MIB II (RFC 1213) To be determined. 4.2 Relation to Interface Group (RFC1573) To be determined. o IfIndex is used in the dlswIfTable to show/control what interfaces DLSw is active on. 4.3 Relation to 802.2 MIB To be determined. 4.4 Relation to SDLC MIB To be determined. 4.5 DLSw MIB Structure The DLSw MIB module contains the following groups of objects: dlswNode objects related to DLSw node configuration, monitoring and control. To be complete 4.5.1 Conformance statement (To be complete) Possible conformance groups are: dlswGroup The mandatory group. dlswNBGroup Agents for DLSw products that do not support NETBIOS should not be required to support NETBIOS-specific objects. Expires April 1996 [Page 6] Internet Draft DLSw MIB Using SNMPv2 ((951009 -- v6.0)) October 1995 dlswCapExOptionalGroup Agents do not support or keep those optional Capabilities Exchange control vectors. dlswPartnerConfigGroup for agents wish to provide configuration per partner basis. dlswDirGroup for agents wish to provide directory information. dlswDirSearchGroup for agents wish to support SNMP interface to invoke directory search. dlswExtStatGroup for agents wish to provide extensive statistics. More 4.6 DLSw MIB special features 4.6.1 Cooperative DLSw nodes It is assumed that all DLSw nodes support this MIB. It is admissible for network management stations to retrieve operational data from various DLSw nodes to form the complete picture of the operational state of a resource. Thus, duplication of MIB information among DLSw nodes is reduced. An example is that the SAP list, NETBIOS list and MAC list are kept at the receiving end of a DLSw capabilities exchange (the sender does not save what it sent to each partner). Note well: The DLSw protocol does not specify a technique for a management station to correlate the transport address of the partner managed DLSw node and the transport address that the management protocol uses. 4.6.2 Setting Capabilities Exchange related objects This MIB supports changes to DLSw variables whose change should be reported to DLSw partner nodes in a "run-time" capabilities exchange. Since a DLSw node normally unicasts these capabilities messages to all its active partners, frequent changes to these variables can result in excessive network traffic. To avoid this problem, developers of network management applications using this MIB should try to group all such changes in a few SNMP SET requests, and should send them in bulk. Agent developers should implement a technique to group a number of changes into a single capabilities exchange message. One possible approach is to send a run-time capabilities message only if no capabilities-related changes have been received for a pre-defined period of time. 4.6.3 Sample usages of the Transport Connection Configuration Table 4.6.3.1 How to configure a DLSw that can accept dynamic partners Expires April 1996 [Page 7] Internet Draft DLSw MIB Using SNMPv2 ((951009 -- v6.0)) October 1995 Define a conceptual row in Transport Connection Configuration table as a "global" row with setupType equal to "passive." For instance, Domain TAddr EntryType SetUpType ------------- ------------- ------------- ------------ dlswTCPDomain '00000000'H global passive 0.0.0.0 4.6.3.2 How to change the configuration of a active transport connection? The configuration of an active transport connection can be changed by the following sequence of management protocol set operations. 1. Locate the TConnConfig entry that governs the configuration of the transport connection. 2. Change the rowStatus of that conceptual row to notInService. Thus, it prevents the transport connection from being connected. 3. Quiesce the TConnOper entry or disconnecting to force. 4. Change the definition of the TConnConfig 5. Change the rowStatus of that conceptual row to active. 6. Change the dlswTConnConfigSetupType to active/passive. 4.6.3.3 How to identify a back-level partner DLSw? If the dlswTConnOperState is in the "connected" state and the dlswTConnOperPartnerVersion is s string of zero length, the partner DLSw can be assumed to be an RFC 1434+ node. 4.6.3.4 How to take down a transport connection? It can be taken down by changing the state of TConnOperEntry to quiescing or disconnecting state.

Virtual data links are used to represent any internal end stations. There is a conceptual row associated with each data link. Thus, for circuits without an intervening transport connection, there are two conceptual rows for each circuit. The table consists of the circuits being established, established, and as an implementation option, circuits that have been disconnected. For circuits carried over transport connections, an entry is created after the CUR_cs was sent or received. For circuits between two locally attached devices, or internal virtual MAC addresses, an entry is created when the equivalent of CUR_cs sent/received status is reached. End station 1 (S1) and End station 2 (S2) are used to represent the two end stations of the circuit. S1 is always an end station which is locally attached. S2 may be locally attached or remote. If it is locally attached, the circuit will be represented by two rows indexed by (A, B) and (B, A) where A & B are the relevant MACs/SAPs. The table may be used to store the causes of disconnection of circuits. It is recommended that the oldest disconnected circuit entry be removed from this table when the memory space of disconnected circuits is needed." ::= { dlswCircuit 2 } dlswCircuitEntry OBJECT-TYPE SYNTAX DlswCircuitEntry MAX-ACCESS not-accessible STATUS current DESCRIPTION "" INDEX { dlswCircuitS1Mac, dlswCircuitS1Sap, dlswCircuitS2Mac, dlswCircuitS2Sap } ::= { dlswCircuitTable 1 } DlswCircuitEntry ::= SEQUENCE { dlswCircuitS1Mac MacAddressNC, dlswCircuitS1Sap OCTET STRING, dlswCircuitS1IfIndex INTEGER, dlswCircuitS1DlcType DlcType, dlswCircuitS1RouteInfo OCTET STRING, dlswCircuitS1CircuitId OCTET STRING, dlswCircuitS1Dlc InstancePointer, Expires April 1996 [Page 54] Internet Draft DLSw MIB Using SNMPv2 ((951009 -- v6.0)) October 1995 dlswCircuitS2Mac MacAddressNC, dlswCircuitS2Sap OCTET STRING, dlswCircuitS2Location EndStationLocation, dlswCircuitS2TDomain OBJECT IDENTIFIER, dlswCircuitS2TAddress TAddress, dlswCircuitS2CircuitId OCTET STRING, dlswCircuitOrigin INTEGER, dlswCircuitEntryTime DlswTimeStamp, dlswCircuitStateTime DlswTimeStamp, dlswCircuitState INTEGER, dlswCircuitPriority INTEGER, dlswCircuitFCSendGrantedUnits INTEGER, dlswCircuitFCSendCurrentWndw INTEGER, dlswCircuitFCRecvGrantedUnits INTEGER, dlswCircuitFCRecvCurrentWndw INTEGER, dlswCircuitFCLargestRecvGranted Gauge32, dlswCircuitFCLargestSendGranted Gauge32, dlswCircuitFCHalveWndwSents Counter32, dlswCircuitFCResetOpSents Counter32, dlswCircuitFCHalveWndwRcvds Counter32, dlswCircuitFCResetOpRcvds Counter32, dlswCircuitDiscReasonLocal INTEGER, dlswCircuitDiscReasonRemote INTEGER, dlswCircuitDiscReasonRemoteData OCTET STRING } -- ................................................................... -- Information related to the End Station 1 (S1). -- ................................................................... dlswCircuitS1Mac OBJECT-TYPE SYNTAX MacAddressNC MAX-ACCESS not-accessible STATUS current DESCRIPTION "The MAC Address of End Station 1 (S1) used for this circuit." ::= { dlswCircuitEntry 1 } dlswCircuitS1Sap OBJECT-TYPE SYNTAX OCTET STRING (SIZE(1)) MAX-ACCESS not-accessible STATUS current DESCRIPTION "The SAP at End Station 1 (S1) used for this circuit." ::= { dlswCircuitEntry 2 } dlswCircuitS1IfIndex OBJECT-TYPE Expires April 1996 [Page 55] Internet Draft DLSw MIB Using SNMPv2 ((951009 -- v6.0)) October 1995 SYNTAX INTEGER (0..2147483647) MAX-ACCESS read-only STATUS current DESCRIPTION "The IfEntry index of the local interface through which S1 can be reached." ::= { dlswCircuitEntry 3 } dlswCircuitS1DlcType OBJECT-TYPE SYNTAX DlcType MAX-ACCESS read-only STATUS current DESCRIPTION "The DLC protocol in use between the DLSw node and S1." ::= { dlswCircuitEntry 4 } dlswCircuitS1RouteInfo OBJECT-TYPE SYNTAX OCTET STRING (SIZE (0..30)) MAX-ACCESS read-only STATUS current DESCRIPTION "If source-route bridging is in use between the DLSw node and S1, this is the routing information field describing the path between the two devices.
