Common management information service
Encyclopedia
The Common Management Information Service (CMIS) is the service interface specified in ITU-T Recommendation X.710, ISO/IEC International Standard 9595 that is employed by OSI network elements for network management. It defines the service interface that is implemented by the Common Management Information Protocol

Services

The following services are made available by the Common Management Information Service Element (CMISE) to allow management of network elements:

Management operation services

  • M-CREATE – Create an instance of a managed object
  • M-DELETE – Delete an instance of a managed object
  • M-GET – Request managed object attributes (for one object or a set of objects)
  • M-CANCEL-GET – Cancel an outstanding GET request
  • M-SET – Set managed object attributes
  • M-ACTION – Request an action to be performed on a managed object

Management association services

Information in its most restricted technical sense is a message or collection of messages that consists of an ordered sequence of symbols, or it is the meaning that can be interpreted from such a message or collection of messages. Information can be recorded or transmitted. It can be recorded as...

 between open systems using CMIS/CMIP, peer connections, i.e., associations, must be established. This requires the establishment of an Application layer

and these services were removed. Below is a list of these services which were subsequently removed from ISO 9595:
  • M-INITIALIZE – Creates an association with (i.e. connects to) another CMISE
  • M-TERMINATE – Terminates an established connection
  • M-ABORT – Terminates the association in the case of an abnormal connection termination
