Common Management Information Protocol (CMIP) is a protocol used for network management. It provides the implemetnation of services defined by common management information service (CMIS).
CMIP works with two other Layer 7 OSI protocols, ASCE (Association Control Service Element) and ROSE (Remote Operations Service Element Protocol). The former manages associations between management applications, i.e. connections between CMIP agents; and the later handles data exchange interactions. However, there are 6 other lower level OSI Layers; and CMIP assumes all of them are present, yet does not assume or specify their various roles and functions.
Techopedia Explains Common Management Information Protocol
CMIS is a service employed by network elements to manage networks; and it defines how the service interfaces with network elements. Implementing that interface is done by the CMIP. The two terms are sometimes erroneously interchanged, e.g. CMIP used when CMIS is meant.
Typically, in the telecommunications industry a network management system utilizes management operation services for monitoring network elements. Management notification services are used by network elements that employ management agents to communicate notifications or alarms back to the network management system.
Common Management Information Protocol was originally designed as a replacement for SNMP, which is less sophisticated with far fewer features, but more widely adopted. For example, CMIP allows the definition of any type of action; whereas SNMP defines only a limited number of actions to alter the state of a managed device.
