Please check the I-D abstract listing contained in each Internet Draft directory to learn the current status of this or any other Internet Draft. 2. Abstract This Internet-Draft defines an extension to the Management Information Base (MIB) for use with SNMP-based network management. In particular, it defines objects for managing the configuration, monitoring and control of data link controls in an SNA environment. This draft identifies managed objects for SNA Synchronous Data Link Control (SDLC) links only. 2, 3. This memo does not specify a standard for the Internet community. Expires April 13, 1994 [Page 2] Internet Draft SNADLC MIB October 1993 3. 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 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. 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 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. Expires April 13, 1994 [Page 3] Internet Draft SNADLC MIB October 1993 4. Overview The SNADLC MIB is composed of two managed entities with, at most, 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. Not all managed entities have all three tables. The following are the actual tables found in this MIB: 1) Port Administration Table, 2) Port Operation Table, 3) Link Station Administration Table, 4) Link Station Operation Table, 5) Link Station Statistics Table, There is no Port Statistics Table since most of the statistics relevant to a particular port are a part of the RS-232 MIB in RFC1317.
