The SNMPv2 Network Management Framework. The major components of the SNMPv2 Network Management framework are described in the documents listed below. o RFC 1902 [1] defines the Structure of Management Information (SMI), the mechanisms used for describing and naming objects for the purpose of management. o STD 17, RFC 1213 [2] defines MIB-II, the core set of managed objects (MO) for the Internet suite of protocols. o RFC 1905 [3] defines the protocol used for network access to managed objects. Textual conventions are defined in RFC 1903 [4], and conformance statements are defined in RFC 1904 [5]. The framework is adaptable/extensible by defining new MIBs to suit the requirements of specific applications/protocols/situations. 1.1. Object Definitions. Managed objects are accessed via a virtual information store, the 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, which is 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, often a textual string, termed the descriptor, is used to refer to the object type. 2. The Directory Services Model. The Directory comprises of Directory Servers. Clients or Directory User Agents (DUA) are provided access to the Directory which maybe local or distributed, by the Directory Servers. The server maybe a X.500 Directory System Agent (DSA) [6] running over the OSI suite of protocols or, a (C)LDAP[7,8] frontend to the X.500 Directory System Agent or, a native LDAP Directory Server running directly over TCP or other protocols, or a database acting as a backend to another server, or any other application protocol, or any combination of the above. A Directory Server has one or more application protocol interfaces. Through these interfaces the Directory Server interacts with the DUA and with the peer Directory Servers. Expires: January 25, 1998 [Page 2] Internet Draft July 25 1997 Fig. 1 shows the case of a Directory Server that receives requests and sends back responses in some protocol. Fig. 2 shows one possible scenario where the Directory Server speaks multiple protocols. +----------------+ | | | Directory | Directory Protocol | Server X--------> | | | | +----------------+ FIG. 1. +----------------+ | | DSP <----------X X--------> DAP | Directory | Other | Server | Protocol <----------X X--------> LDAP | | +----------------+ FIG. 2. The Directory contains information in the form of entries. An entry is a collection of attributes and is uniquely identified by a name, the Distinguished Name (DN). The entries are arranged in a hierarchical tree-like structure called the Directory Information Tree (DIT). A DUA requests a Directory Server to perform some operation on the Directory. The Directory Server is responsible for performing the operation and after completing its effort to carry out the request, returns a response to the DUA. A Directory Server may use information stored in its local database or interact with (chain the request to) other Directory Servers to service the DUA request. Alternatively, a Directory Server may return a reference to another Directory Server (referral). The local database of a Directory Server consists of the part of the Directory that is mastered by the Directory Server, the part of the Directory for which it keeps slave copies and cached information that Expires: January 25, 1998 [Page 3] Internet Draft July 25 1997 is gathered during the operation of the Directory Server. In the connection oriented mode a DUA "binds" to a Directory Server with a particular identification. The Directory Server may authenticate the identity of the DUA. In the connectionless mode as is employed in CLDAP [CLDAP] no binding and/authentication is carried out between the DUA and the Directory Server. The following type of operations are carried out by the Directory Server : Read, Compare, Addition of an Entry (AddEntry), Modification of an Entry (ModifyEntry), Modification of a DN (ModifyRDN), Deletion of an Entry (RemoveEntry), List, Search, Abandon. Some Directory Servers do not support some type of operations. For example CLDAP does not support AddEntry, ModifyEntry, ModifyRDN, RemoveEntry etc. In response to requests results and/or errors are returned by the Directory Server. In the distributed Directory data is often replicated to enhance performance and for other advantages. The data to be replicated is transferred from the "Supplier" Directory Server to the "Consumer" Directory Server according to the replication agreement between the supplier and the receiver. 3. MIB Model for Directory Management. A Directory manager must be able to monitor all the Directory Servers in his/her domain of management. The Directory Servers may be running on one or more hosts and, multiple Directory Servers may be running on the same host. The manager may wish to monitor several aspects of the operational Directory Servers. He/she may want to know the process related aspects- the resource utilization of an operational Directory Server; the network service related aspects e.g. inbound-associations, outbound-associations, operational status, and finally the information specific to the Directory Server application- its operations and performance. The MIB defined in this document covers the portion which is specific to Directory services. The network service related part of the MIB, and the host-resources related part of the MIB, as well other parts of interest to a Manager monitoring the Directory services, are covered in separate documents [9][10]. The MIB will cover a group of Directory Servers. The grouping will be done on some logical basis by the administrator/manager. In all cases, the grouping will be reflected in the pertinent NETWORK- SERVICES-MIB which must have an entry corresponding to each Directory Expires: January 25, 1998 [Page 4] Internet Draft July 25 1997 Server in the group. 4. MIB design. The basic principle has been to keep the MIB as simple as possible. The Managed objects included in the MIB are divided into three tables- dsaTable, dsaOpsTable, and dsaIntTable. - The dsaTable contains a list of Directory Servers. The list contains a description of the Directory Servers as well as summary statistics on the entries held by and the cache performance of each Directory Server. The group of servers on this list is likely to contain a part of, if not all, the Directory Servers in the management domain. - The dsaApplIfOpsTable provides summary statistics on the accesses, operations and errors for each application protocol interface of a Directory Server. - The dsaIntTable provides some useful information on the interaction of the monitored Directory Servers with peer Directory Servers. There are references to the Directory itself for static information pertaining to the Directory Server. These references are in the form of "Directory Distinguished Name" [11] of the corresponding object. It is intended that Directory management applications will use these references to obtain further information on the objects of interest.
