scope:

This International Standard defines an Open Systems Interconnection (OSI) management-compatible architecture, and service and protocol elements for use in a LAN/MAN environment for the purpose of performing remote management of LAN-based or MAN-based devices. The protocol described is a connectionlessmode management protocol that makes use of Logical Link Control (LLC) Type 1 procedures as a means of conveying management information between stations in a LAN/MAN environment, thus providing for interworking of ISO/IEC standard LAN/MAN devices for management purposes. The management information is conveyed using the protocol data unit (PDU) formats defined in ISO/IEC 9596-1 : 1991.¹ To this end, this International Standard

a) Describes the services required for the transfer of management information between management processes in LAN/MAN stations.

b) Defines the protocol and PDUs for conducting management information exchanges that support the provision of those services. This protocol is defined as an (N)-layer management protocol specific to the management of layers 1 and 2 in a LAN/MAN environment.

c) Defines a convergence protocol and PDUs used for the exchange of management PDUs.

d) Describes the underlying services required for transfer of management PDUs between peer-management entities by means of the convergence protocol.

e) Defines an access control mechanism and an event report forwarding mechanism that operate in conjunction with the management protocol.

f) Defines managed object classes that relate to the operation of the management protocol and the convergence protocol. 

This International Standard provides the PICS proforma for the System Load Protocol in compliance with the relevant requirements, and in accordance with the relevant guidance, given in ISO/IEC 9646-2: 1991.

NOTES

1-This International Standard provides only a set of management tools. The management operations that are specified by this Intemational Standard are only meaningful in conjunction with the managed object definitions contained in the appropriate layer standards.

2-This International Standard defines an (N)-layer management protocol for the management of stations attached to ISO/IEC standard LAN or MAN subnetworks, in accordance with the terminology contained in the OS1 Management Framework, ISO/IEC 7498-4 : 1989 and the OS1 Systems Management Overview, ISO/IEC 10040 : 1992. The service and protocol described in this International Standard are based upon the OS1 Common Management Information Service and Protocol standards (ISO/IEC 9595 : 1991 and ISO/IEC 9596-1 : 1991), and are therefore designed to be used in conjunction with managed objects defined in accordance with the Guidelines for the definition of managed objects (ISO/IEC 10165-4 : 1992). As such, this International Standard is intended to be complementary to the functionality of the OS1 Management standards being developed in ISO/IEC JTCI SC21/WG4.

3-To evaluate conformance of a particular implementation, it is necessary to have a statement of which capabilities and options have been implemented for a given protocol. Such a statement is called a Protocol Implementation Conformance Statement (PICS). Annex A to this International Standard contains the PICS profonna for the LANIMAN Management Protocol.
