The SNMPv2 Network Management Framework + + The SNMPv2 Network Management Framework consists of four major + components. They are: + + o RFC 1441 which defines the SMI, the mechanisms used for + describing and naming objects for the purpose of management. + + o STD 17, RFC 1213 defines MIB-II, the core set of managed + objects for the Internet suite of protocols. + + o RFC 1445 which defines the administrative and other + architectural aspects of the framework. + + o RFC 1448 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. + +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 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. Overview + + This memo identifies the proposed set of objects for configuring, + monitoring, and controlling SDLC ports and link stations. + + + + + + + + + +Hilgeman, Nix, Bartky & Clark [Page 2] + +RFC 1747 SNADLC SDLC MIB using SMIv2 January 1995 + + +2.1. Tables Defined in the SNADLC SDLC MIB + + The SNADLC MIB is composed of two managed entities with three tables + each. The two managed entities for SDLC are: + + o Ports: the physical connection, and + + o Link Stations: the logical connections on the Port. + + The three management tables are: + + o Adminstration: objects used for configuring and controlling + the operation of a Port or Link Station, + + o Operational: objects that reflect the run-time state of the + Port or Link Station, and + + o Statistics: objects that reflect the operating metrics of the + Port or Link Station. + + Considering the above combinations, the following are the actual + tables found in this MIB: + + 1) Port Administration Table, + + 2) Port Operation Table, + + 3) Port Statistics Table, + + 4) Link Station Administration Table, + + 5) Link Station Operation Table, + + 6) Link Station Statistics Table. + + All variables in this MIB relate to SDLC ports and link stations + only. Any variable relating to higher-layer entities in SNA such as + Physical Units (PU) and Logical Units (LU) are found in the SNA NAU + MIB [4]. + +2.2. Row Creation Mechanism + + Row creation mechanism for the sdlcLSAdminTable is based on the use + of the RowStatus object. It follows the rules for the use in SNMPv1 + context proposed in the memo "Row creation with SNMPv1" [5]. Before + accepting the destroy value for an entry, an agent has to verify the + operational state of the corresponding entry in the sdlcLSOperTable + entry. + + + +Hilgeman, Nix, Bartky & Clark [Page 3] + +RFC 1747 SNADLC SDLC MIB using SMIv2 January 1995 + + +2.3. Relationship to the Interfaces Group + + This memo shall conform to the recommendations of [6]. + + The SDLC layer of each SDLC Port shall be modeled by a row in the + ifTable with an ifType using the IANA assigned number for SDLC (17). + Each SDLC port interface must comply with the following conformance + groups in [6]: + + - ifGeneralGroup + - ifStackGroup + - ifPacketGroup + + An implementation may optionally comply with the ifTestGroup defined + in that memo to execute vendor specific tests. An example of this + would be to perform LPDA test functions. + + The SDLC port's relation with its physical, or lower-layer interface + (i.e., RS-232, V.35, etc.) shall be modeled by a row in the + ifStackTable with the ifStackHigherLayer pointing to the SDLC port + ifTable instance and the ifStackLowerLayer pointing to the physical + media-specific ifTable instance. The media-specific objects of these + lower-layer interfaces will, of course, be described in their + respective MIBs (i.e., [1]). + + The following table provides specific implementation guidelines for + all the interface group objects listed in the conformance tables + above. + +Object Use for an SDLC Port + +ifIndex Each SDLC port is represented by an ifEntry. All + SDLC port tables shall be indexed by ifIndex. + +ifDescr Description of the SDLC port. + +ifType The IANA value reserved for SDLC - 17. + +ifMtu Refer to [6]. + +ifSpeed This object shall reflect the value of the + corresponding object in the ifEntry of the + associated lower-layer interface. + +ifPhysAddress A string denoting the physical location of the SDLC + port within its node. This shall have unique + significance within each implementing node. + + + + +Hilgeman, Nix, Bartky & Clark [Page 4] + +RFC 1747 SNADLC SDLC MIB using SMIv2 January 1995 + + +ifAdminStatus This object shall reflect the value of the + corresponding object in the ifEntry of the + associated lower-layer interface. + +ifOperStatus This object shall reflect the value of the + corresponding object in the ifEntry of the + associated lower-layer interface. + +ifLastChange Refer to [6]. + +ifInOctets Refer to [6]. + +ifInUcastPkts This object shall count packets received from a + specific SDLC poll address. Packets for the SDLC + broadcast address of x'FF' are not counted. + +ifInDiscards Refer to [6]. + +ifInErrors Refer to [6]. Specific counters for these errors + are kept in the sdlcPortStatsTable. + +ifInUnknownProtos This counter shall return zero for SDLC ports. + +ifOutOctets Refer to [6]. + +ifOutUcastPkts This object shall count packets transmitted to a + specific SDLC poll address (not x'FF'). + +ifOutDiscards Refer to [6]. + +ifOutErrors Refer to [6]. Specific counters for these errors + are kept in the sdlcPortStatsTable. + +ifName The textual name of the SDLC port or an octet string + of zero length. + +ifInMulticastPkts The value is 0 (not applicable to the SDLC layer). + +ifInBroadcastPkts This object shall count packets received on this + interface addressed to the SDLC broadcast address + (x'FF'). Only point-to-point ports supporting a + secondary switched station should return non-zero + values. + +ifOutMulticastPkts The value is 0 (not applicable to the SDLC layer). + +ifOutBroadcastPkts This object shall count packets transmitted on this + interface which were addressed to the SDLC broadcast + + + +Hilgeman, Nix, Bartky & Clark [Page 5] + +RFC 1747 SNADLC SDLC MIB using SMIv2 January 1995 + + + address (x'FF'). Only point-to-point ports + supporting a primary switched station should + return non-zero values. + +ifHC* Not part of the conformance group. + +ifLinkUpDownTrapEnable + Refer to [6]. Default is disabled (2). + +ifHighSpeed Refer to [6]. + +ifPromiscuousMode Should return false if this interface receives only + packets addressed to its SDLC poll address(es). + However, in certain implementations, the lower-layer + interface shall present all frames to the SDLC port + regardless of the poll address. Such frames may be + the result of a misconfigured peer or the secondary + end of a multipoint connection. Such + implementations should return true for this + object. + +ifConnectorPresent Set to 'false'. + +ifStackHigherLayer For each SDLC port there will be an ifStackEntry + with this object's value referring to the ifIndex of + the SDLC port's ifEntry for the SDLC layer. + +ifStackLowerLayer For each SDLC port there will be an ifStackEntry + with this object's value referring to the ifIndex of + the physical layer interface's ifEntry for that SDLC + port. + +ifStackStatus Refer to [6]. + + + + + + + + + + + + + + + + + + +Hilgeman, Nix, Bartky & Clark [Page 6] + +RFC 1747 SNADLC SDLC MIB using SMIv2 January 1995 + + +3.

Glossary + + link station + A link station comprises procedures and control information + that coordinate the transfer of data between two nodes joined + by a link connection. All traffic over the link connection is + from the primary link station to one or more secondary link + stations, or from a secondary link station to the primary link + station. + + primary link station + The link station instance on a link connection that is + responsible for the control of the data link. There must be + only one primary link station on a link connection. The + primary link station issues commands to one or more secondary + link stations. + + secondary link station + The link station instance on a link connection that receives + commands from the primary link station and issues responses to + it. + + switched line + A telecommunications line in which the connection is + established by dialing. For switched lines, the SDLC startup + sequence typically begins with a null exchange identifier (null + XID). + + leased line + A telecommunications line on which connections do not have to + be established by dialing. For leased lines, the SDLC startup + sequence may or may not begin with an exchange identifer (XID). + While there are interface (e.g., RS.232) differences between + leased and switched lines, those interface differences do not + map one-to-one with differences in the SDLC startup protocol + (i.e., the interface and the SDLC protocol are independent from + one another). + + point-to-point link + A link that connects the single primary link station to single + secondary link station. A point-to-point link may be either + switched or leased. + + multipoint link + A link that connects the single primary link station to several + secondary link stations. A multipoint link may be either + switched or leased. Note: The physical interface signals for a + multipoint link are different than for a point-to-point link. + + + +Hilgeman, Nix, Bartky & Clark [Page 66] + +RFC 1747 SNADLC SDLC MIB using SMIv2 January 1995 + + + Synonymous with multidrop line. + +7.
