They are: + + RFC 1902 [2] which defines the SMI, the mechanisms used for + describing and naming objects for the purpose of management. + + STD 17, RFC 1213 [4] defines MIB-II, the core set of managed + objects for the Internet suite of protocols. + + STD 15, RFC 1157 [5] and RFC 1905 [6] which define two versions of + the protocol used for network access to managed objects. + + The Framework permits new objects to be defined for the purpose of + experimentation and evaluation. + +1.1 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 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. + +2.0 Overview + + This memo identifies the set of objects for configuring, monitoring, + and controlling Data Link Switches. + +2.1 Relation to Interface Group (RFC 1573) [8] + +o ifIndex is used as the index into dlswIfTable, which shows and + controls the interfaces that DLSw is active on. + +o Local entries in the MAC address and NetBIOS (NB) name caches can + point to an ifEntry to indicate the interface through which DLSw can + reach that MAC address or NB name. See the objects + dlswDirMacLocation and dlswDirNBLocation. + +o Local entries in the circuit table use ifIndex to indicate the + interface through which DLSw is connected to the local end station. + + + +Chen, et. al. Standards Track [Page 2] + +RFC 2024 DLSw MIB using SMIv2 October 1996 + + + See the object dlswCircuitS1Index. + +o ifIndex is the primary index into dlswSdlcLsTable, which lists the + SDLC stations DLSw is serving. + +2.2 Relation to Underlying DLC Layer + + The DLSw MIB does not duplicate the information in the MIBs for the + DLC layer underneath it. Instead, each circuit table entry contains + a pointer to a conceptual row in an underlying enterprise-specific or + standard DLC MIB. + + Using the 802.2 LLC management as an example, the following rules + should be considered when developing new DLSw related DLC MIBs, and + when implementing the interactions between DLSw MIB and DLC MIBs: + +o The referenced row should represent the local LLC-2 (and/or LLC-1, + if supported) link station that DLSw is using. In the current 802.2 + LLC MIB draft, this might be a row of one of the tables + llcCcAdminTable, llcCcOperTable, or llcCcStatsTable. + + A circuit using local LLC services will therefore have + dlswCircuitS1DlcType = llc, and dlswCircuitS1Dlc = pointer to an LLC + MIB table row. + +o Because DLSw is the user of LLC services, it is generally preferable + to initiate administrative actions using the DLSw MIB and allow DLSw + to control LLC directly, rather than starting with LLC MIB + administrative actions. For example, a hung circuit should be + disconnected by setting dlswCircuitState, as opposed to setting + llcCcAdminStatus to disable the LLC part of the circuit. Similarly, + setting bits in dlswIfSapList will cause row creation in + llcSapOperTable as well as set the necessary DLSw-LLC relationship. + +2.3 Relation to SDLC MIB (RFC 1747) + + The general comments stated in 2.2, "Relation to Underlying DLC + Layer" apply to the SDLC MIB. The following apply if the DLSw MIB is + implemented in a product that also implements RFC 1747 [9]: + +o The row referenced from dlswCircuitS1Dlc should represent the local + SDLC link station that DLSw is using. This might be a row of one of + the tables sdlcLSAdminTable, sdlcLSOperTable, or sdlcLSStatsTable. + + A circuit using local SDLC services will therefore have + dlswCircuitS1DlcType = sdlc, and dlswCircuitS1Dlc = OID of one of + these table rows. + + + + +Chen, et. al. Standards Track [Page 3] + +RFC 2024 DLSw MIB using SMIv2 October 1996 + + +o dlswSdlcLsTable uses the same indices that are used to index link + station information in RFC 1747. This table provides a mapping + between this native SDLC addressing (interface, link station + address) and the addressing used in the DLSw domain (local MAC and + SAP). + +2.4 DLSw MIB Structure + + See 3 .0, "Definitions" on page 11 for a diagram outlining the DLSw + MIB structure. The following groups of objects are included: + + dlswNode Objects related to this DLSw node's configuration, + monitoring and control. + + dlswTConn Objects relating to transport connections to this + DLSw's partner nodes. + + dlswInterface Objects configured for this DLSw relating to its local + interfaces. + + dlswDirectory Objects reflecting this DLSw's view of where + end-station resources (MAC addresses and NetBIOS names) + are located. + + dlswCircuit Objects showing the end-station connections that + DLSw currently has established, or that are coming up + or have gone down. + + dlswSDLC Objects configured for this DLSw's SDLC-attached end + stations. + +2.4.1 Compliance + + The MIB provides the following compliance statements: + + dlswCoreCompliance Defines the minimum support required of all + implementations. Note that for this and the + other compliance statements, NetBIOS-related + objects are grouped separately because the + DLSw Version 1 Standard [1] does not require + NetBIOS support. + + dlswTConnTCPCompliance Defines the minimum support required of + implementations that use TCP as a transport + protocol. + + dlswDirCompliance Defines the minimum support required of + implementations that support some sort of + + + +Chen, et. al. Standards Track [Page 4] + +RFC 2024 DLSw MIB using SMIv2 October 1996 + + + directory function. + + dlswDirLocateCompliance Defines the minimum support required of + implementations that support a directory + function and also support the ordered + retrieval of the entries that match a given + resource. + + dlswSdlcCompliance Defines the minimum support required of + implementations that support SDLC-attached + end stations. +2.5 DLSw MIB Usage + +2.5.1 Cooperative DLSw nodes + + To reduce the size of the MIB, thus the amount of data that each + agent needs to keep, the information that usually could be made + available in two partner nodes (e.g., information exchanged between + them) is only defined in the MIB as the info received. That is, + there are no objects defined for the info sent. In order to form the + complete picture of the state of a resource, the manager needs to + retrieve info from multiple DLSw nodes. 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 + manager to correlate the transport address of the partner managed + DLSw node and the transport address that the management protocol + uses. + +2.5.2 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. + + + + + + +Chen, et. al. Standards Track [Page 5] + +RFC 2024 DLSw MIB using SMIv2 October 1996 + + +2.5.3 Examples of Tasks Using This MIB + +2.5.3.1 Configuring DLSw to actively connect to a specific TCP/IP + partner + + Create a conceptual row in dlswTConnConfigTable with: Index = the + highest the managed station has used so far + 1; TDomain = + dlswTCPDomain; LocalTAddr = this node's DLSw IP address; RemoteTAddr + = the partner's DLSw IP address; EntryType = individual; SetupType = + activePersistent. Note that determining the index to use may require + dumping the TConnConfigTable, but this will not typically be a large + table. If the DLSw node rejects the row creation due to index + collision, the management station should increment its index value + and try again. + +2.5.3.2 Configuring DLSw to passively accept any partner + + Create a conceptual row in dlswTConnConfigTable as above but with: + RemoteTAddr = 0; EntryType = global; SetUpType = passive. Every + individual transport connection accepted as a result of this global + row will inherit the configuration values from this row. + + To prevent a specific remote node from being passively accepted as a + partner, create another row with: RemoteTAddr = that node's IP + address; EntryType = individual; SetupType = excluded. + +2.5.3.3 Configuring DLSw to allow or connect to a group of partners + + Define a conceptual row in dlswTConnConfigTable as above but with: + EntryType = group; GroupDefinition = pointer to an enterprise- + specific representation of a group. For example, a group definition + might consist of an IP address value and mask, or a multicast IP + address. Every individual transport connection accepted as a result + of this group row will inherit the configuration values from this + row. + + When a group is created that has some overlap with entries where + EntryType = individual (there will always be this overlap when a + global row exists), the DLSw node must use the configured rows using + a "most specific match wins" rule. That is, the entry in + TConnConfigTable with the remote address most nearly matching an + incoming connection should be used to provide the values for the new + connection. For equal matches, the choice of TConnConfigTable entry + is up to the DLSw node implementation. Note that the management + station should never create two TConnConfig rows with duplicate + remote addressing values. + + + + + +Chen, et. al. Standards Track [Page 6] + +RFC 2024 DLSw MIB using SMIv2 October 1996 + + +2.5.3.4 Identifying the protocol level of a partner DLSw + + If the partner DLSw has implemented at least the AIW Version 1 DLSw + Standard [1], the AIW version and release number for the DLSw + protocol is accessible from dlswTConnOperPartnerVersion. If + TConnOperPartnerVersion is a string of zero length but the + TConnOperState = `connected' state (i.e., is not still performing + capabilities exchange), the partner DLSw can be assumed to be an RFC + 1434+ node. + +2.5.3.5 Recycling a transport connection + + Quiesce or forcibly disconnect the transport connection by setting + TConnOperState to `quiescing' or `disconnecting', and monitor until + it moves to the `disconnected' state or the TConnOper row disappears. + The row may disappear because implementations are not required to + maintain transport connection information after a transport + connection has gone down. + + The action required to re-activate the transport connection depends + on the value of TConnConfigSetupType for the relevant TConnConfig + row. ActivePersistent connections will attempt to come back + automatically. Passive connections must be re-established from the + remote partner. ActiveOnDemand connections will be re-established by + this node, but only after some end-station operation triggers a + circuit setup attempt. + +2.5.3.6 Investigating why a transport connection went down + + TConnOperDiscTime and TConnOperDiscReason provide the vital + information of the time and the cause of the disconnection of a + transport connection and TConnOperDiscActiveCir indicates whether end + users may have been affected. This MIB does not specify the duration + that an agent must make this information available after the + disconnection of a transport connection occurs. Manager should try + the agent of the partner DLSw, if such information is not available + in one DLSw node. Additional information might come from the MIB for + the transport protocol (e.g., TCP or LLC). dlswTConnStat* and + dlswTConnConfigOpens give a more general picture of transport + connection activity, but can't give specific reasons for problems. + +2.5.3.7 Changing the configuration of an active transport connection + + Follow this sequence of managment protocol set operations: + + 1. Use TConnOperConfigIndex to locate the TConnConfig entry that + governs the configuration of the transport connection. + + + + +Chen, et. al. Standards Track [Page 7] + +RFC 2024 DLSw MIB using SMIv2 October 1996 + + + 2. Change the rowStatus of that conceptual row to notInService. This + prevents the transport connection from being connected automatically + if TConnConfigSetupType = activePersistent. + 3. Quiesce or forcibly disconnect the transport connection by setting + TConnOperState to `quiescing' or `disconnecting', and monitor until + it moves to the `disconnected' state or the TConnOper row + disappears. + 4. Change the values of TConnConfig variables as desired. + 5. Change the rowStatus of the TConnConfig conceptual row to active. + TConnConfigSetupType will subsequently control whether this node + will actively seek to re-establish the transport connection, or will + wait. + +2.5.3.8 Checking configuration validity for an active transport + connection + + Use TConnOperConfigIndex to identify the row of TConnConfig for the + transport connection. If TConnConfigLastModifyTime is greater than + TConnOperConnectTime, then one or more of the variables in the + TConnConfig row may not be valid for the current state of the active + transport connection. This is an exception condition and will not + normally be the case. + +2.5.3.9 Configuring the interfaces and SAPs DLSw will use + + To add DLSw end-station support (not transport connection support) to + an interface, create a conceptual row for that ifIndex in the + dlswIfTable. For many products, you will specify the same single + virtual segment number for all interfaces. Indicate the list of SAPs + to be supported by that interface - this could be all 0xFFs if the + product has some automatic SAP opening function. + + To open or close a SAP to DLSw on an existing interface, simply set + or reset the appropriate bit in dlswIfSapList in the table row for + that interface. + +2.5.3.10 Configuring static MAC address (or NetBIOS name) cache entries + + It is common to configure a few static directory entries to preload + in the caches of the DLSw nodes and reduce the need for broadcast + searches. The following example adds entries to the MAC cache to + indicate that a specific MAC address is reachable through two + different remote partners: + + 1. The manager retrieves dlswDirMacCacheNextIndex to get an index + assignment from the DLSw node. The DLSw node ensures that the + retrieved index will not be reused. + + + + +Chen, et. al. Standards Track [Page 8] + +RFC 2024 DLSw MIB using SMIv2 October 1996 + + + 2. The manager creates a conceptual row in dlswDirMacTable with: + Index = the retrieved index; Mac = the MAC address; Mask = all + 0xFF's; EntryType = userConfiguredPublic; LocationType = remote; + Location = OID for dlswTConnConfigEntry of the 1st partner; Status + = unknown (recommended for new entries). + 3. The manager repeats the preceding 2 steps and creates a second row + using Index = second index retrieved; Location = OID for + dlswTConnConfigEntry of the 2nd partner. + + Note that the DLSw node is not obligated to use newly created + directory entries in the order in which they were created. It is + recommended that entries be used in most-specific match first order, + i.e., an entry with a Mask of all 0xFFs should take precedence over + one with a "partial wildcard". The relative order of static versus + dynamic entries and of "equal length" matches is up to the DLSw + implementation. + + The dlswDirStat objects can be used to get an idea of the success + rate for a particular static caching scheme. + +2.5.3.11 Seeing where the directory indicates a given resource is + + To retrieve all directory information related to a given resource (in + this example, a NetBIOS name), the management station should: + + 1. Retrieve dlswDirLocateNBLocation in the dlswDirLocateNBTable entry + where NBName = the fully-specified NetBIOS name without wildcards; + NBMatch = 1. + 2. Use the returned value (i.e., OID) to retrieve the contents of the + dlswDirNBEntry itself. + 3. Repeat the previous two steps with NBMatch = 2, 3, ..., until the + end of dlswDirLocateNBTable is reached. + + The DLSw node conveys the precedence relationship of the different + matching directory entries by the order in which it returns their + OIDs. + +2.5.3.12 Investigating circuit bringup failure + + Circuit bringup takes place in two stages: explorer flows to locate + the target resource (MAC address or NetBIOS name); and establishing + the circuit itself. To determine the success of explorer flows, have + the origin end station initiate a link establishment to the target, + and look later for cache entries for the target MAC address or + NetBIOS name. The dlswTConn*ex* counters also give some visibility + to which transport connections are being used to look for resources. + Once circuit establishment is started, an entry of dlswCircuitTable + for the two MAC/SAP addresses involved is created. + + + +Chen, et. al. Standards Track [Page 9] + +RFC 2024 DLSw MIB using SMIv2 October 1996 + + + dlswCircuitEntryTime, StateTime, and State may provide useful + information about intermediate states the circuit is reaching before + becoming disconnected again. + +2.5.3.13 Investigating the failure of an established circuit + + The variables dlswCircuitDiscReason* in the dlswCircuitTable provide + the key information of the cause of the disconnection of circuits. + In addition, the underlying DLC MIBs may provide information at the + link station level, and some clues (e.g., DISC or FRMR counters) at + the SAP or interface level. + +2.5.3.14 Seeing circuit-level traffic statistics + + Locate the relevant dlswCircuitEntry and follow dlswCircuitS1Dlc to a + link station-level table entry in the underlying DLC MIB. Move to + the corresponding link station's statistics table in the DLC MIB to + get counters of frames, bytes, etc. for this circuit. + +2.5.3.15 Cutting down the flow of DLSw-related traps + + Set some or all of the dlswTrapCntl* objects to the value of + `disabled' or `partial'. + + + + + + + + + + + + + + + + + + + + + + + + + + + + +Chen, et. al.

This term is used to refer to the +-- association between DLSw nodes without being concerned +-- about whether TCP is the protocol or whether there are +-- one or two TCP connection. +-- (Note: for two TCP connections, the transport connection is +-- opened if and only if both TCP connections are operational. +-- Also note: sometimes race conditions will occur, but the +-- condition should only be temporary.) +-- +-- (4) Data Link: +-- An instance of OSI layer-2 procedures for exchanging information +-- using either connection-oriented (e.g., LLC-2) or connectionless +-- (e.g., LLC-1) services. A DLSw node or pair of partner nodes +-- switches data traffic from stations of one data link to +-- stations of another data link. Data link switching is +-- transparent to end stations. +-- Source: the end station which sends a message. +-- Destination: the end station which receives a message. +-- (This DLSw role is with respect to a give message) +-- +-- (5) Circuit: +-- End-to-end association of two DLC entities through one or +-- two DLSw nodes.
