Common Management Information Protocol
The Common Management Information Protocol (CMIP) is the OSI specified network management protocol.
Defined in ITU-T Recommendation X.711, ISO/IEC International Standard 9596-1. It provides an implementation for the services defined by the
CMIP models management information in terms of
CMIP also provides good security (support authorization, access control, and security logs) and flexible reporting of unusual network conditions.
Services implemented
The management functionality implemented by CMIP is described under CMIS services.
In a typical Telecommunications Management Network, a management system will make use of the management operation services to monitor network elements. Management agents found on network elements will make use of the management notification services to send notifications or alarms to the network management system.
Deployment
CMIP is implemented in association with the ACSE and ROSE protocols. Both are Layer 7 OSI protocols (Application Layer). ACSE is used to manage associations between management applications (i.e. manage connections between CMIP agents). ROSE is employed for all data exchange interactions. Besides the presence of these Layer 7 protocols, CMIP assumes the presence of all OSI layers at lower levels but does not explicitly specify what these should be.
There have been some attempts to adapt CMIP to the TCP/IP protocol stack. Most notable is CMOT contained in RFC 1189 (detailing CMIP over TCP). Other possibilities include RFC 1006 (which provides an ISO transport service on top of TCP), and CMIP over LPP (a presentation layer protocol that can run on top of TCP or UDP).
There is also a form of
