Abstract This memo defines an experimental portion of the Management Information Base (MIB) for use with network management protocols in the Internet community. In particular, it describes managed objects used for managing monitoring of MIB objects and taking action through events. 9 9Expires 21 November 1997+6 months [Page 2] Internet Draft Event MIB 21 November 1997 2. The SNMP Network Management Framework They are: The SNMP Network Management Framework presently consists of three major components. They are: the SMI, described in RFC 1902 [1] - the mechanisms used for describing and naming objects for the purpose of management. the MIB-II, STD 17, RFC 1213 [2] - the core set of managed objects for the Internet suite of protocols. the protocol, RFC 1157 [3] and/or RFC 1905 [4], - the protocol for accessing managed objects. The Framework permits new objects to be defined for the purpose of experimentation and evaluation. 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 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. 9 9Expires 21 November 1997+6 months [Page 3] Internet Draft Event MIB 21 November 1997 3. Overview This MIB is based heavily on the RMON and Manager-to-Manager MIBs. It depends on the services of the Target, Notification, and Expression MIBs. All of this must suit either a relatively powerful manager or mid-level manager, as well as a somewhat more limited self-managing system. 4. Known Problems The error code for a failure comes from a now non-existent MIB. I suppose those codes will need to be transplanted here. The error handling depeds somewhat on notifications and had assumed the existence of a logging MIB, which evaporated as did the above-mentioned error codes. The description of RMON-like threshold operation is broken and needs to be changed to be like RMON. The compliance section is missing. 9 9Expires 21 November 1997+6 months [Page 4] Internet Draft Event MIB 21 November 1997 5.
