and has far more features than SNMP. For example, SNMP defines only "set" actions to alter the state of the managed device, while CMIP allows the definition of any type of action. CMIP was a key part of the Telecommunications Management Network, and enabled cross-organizational as well as cross-vendor network management. On the Internet, however, most TCP/IP devices support SNMP and not CMIP. This is because of the complexity and resource requirements of CMIP agents and management systems. CMIP is supported mainly by telecommunication devices. See also Common Management Information Service (CMIS) CMIP over TCP/IP (CMOT) References CMIP is formally defined by the X.700 series of recommendations from the ITU-T (in particular X.711), and ISO 9596. Some description is also provided in RFC 1095 and RFC 1189 (The Common Management Information Services and Protocols for the Internet).
