SNMP vs. CMIP: What's the Difference?
TechTarget, Thursday, April 30th, 2026
SNMP and CMIP are network management protocols with different design philosophies: SNMP prioritizes simplicity while CMIP emphasizes flexibility.
SNMP (Simple Network Management Protocol) and CMIP (Common Management Information Protocol) were both developed in the late 1980s to manage networks, but they reflect different design philosophies from the internet and OSI communities respectively.
SNMP was designed to be simple and useful with minimal commands like GET and SET, prioritizing efficiency on devices with limited resources, while CMIP was designed to be comprehensive and flexible with additional capabilities such as creating and deleting managed software entities.
SNMP uses straightforward datagram exchanges without maintaining persistent connections, whereas CMIP uses the ROSE protocol to maintain connections and employs Abstract Syntax Notation One for encoding parameters. Although both protocols emerged during a period of competition between the internet and OSI communities, the widespread success of the internet ultimately proved that SNMP's simpler approach could handle traffic loads far beyond what was anticipated in the 1980s and 1990s.
