M-GET, M-SET, M-ACTION, M-CREATE |
| Services |
Internet Management, SNMP uses UDP datagram. |
Telecomm Management, CMIP uses connection-oriented sessions |

CMIP is used for its security, as it supports authorization, access control, and security logs, CMIP uses reporting. |
| Access |
In terms of data access, SNMP retrieves individual items of information also SNMP is more focused. |
CMIP retrieves a collection of information, CMIP deals with classes of data that must be constrained. |
| Uses |
SNMP,used in Local Area Networks (LANs), SNMP is widely used because of its,simplicity. |
CMIP used in Wide Area Networks (WANs) |
