Common Management Information Protocol (CMIP) is a communications protocol that is used for network management. It provides a method for exchanging management information between network devices and systems.

CMIP was developed as a part of the Open Systems Interconnection (OSI) model by the International Organization for Standardization (ISO). It was designed to be a robust and powerful network management protocol, providing detailed management data and supporting complex network management operations.

CMIP is used in conjunction with the Common Management Information Service (CMIS), which defines the set of management operations and managed objects that can be handled using CMIP. Together, CMIP and CMIS provide a comprehensive framework for network management in an OSI environment.

While CMIP is powerful and flexible, it is also complex, which has limited its adoption. In practice, the Simple Network Management Protocol (SNMP), which is simpler and easier to implement, has been more widely used for network management, especially in TCP/IP-based networks.

Here are some features of CMIP:

  1. It has the ability to handle a broader set of operations compared to SNMP.
  2. It provides both confirmed and unconfirmed service types.
  3. It supports more flexible error reporting.
  4. It includes the ability to handle complex, structured data.
  5. It supports security and control features, such as access control.
  6. It can manage both network devices and services.

As of my knowledge cutoff in September 2021, SNMP remains the dominant protocol in network management despite the technical advantages of CMIP, largely due to its simplicity and the widespread adoption of TCP/IP networks.
