Attributes | SNMP | CMIS/CMIP |
---|---|---|
Meaning | The Simple Network Management Protocol (SNMP), which is located in application layer, is part of the Transmission Control Protocol / Internet Protocol (TCP/IP) network architecture. | Common Management Information Protocol (CMIP) is an interface for network management in the Open Systems Interconnection (OSI) Reference Model. |
Information Model | SMI | GDMO |
Function | SNMP is responsible for exchanging data between network devices | Supports information exchange between network management stations and management agents and also supports access to managed information in the managed objects. |
Protocol | GET, SET, TRAP | M-GET, M-SET, M-ACTION, M-CREATE |
Services | Internet Management, SNMP uses UDP datagram. | Telecomm Management, CMIP uses connection-oriented sessions |
Complexity | As a comparison, SNMP only employs the operation attributes and the notifications (Trap messages). | In CMIP, the variables or operations are seen as very complex and sophisticated data structures, with many attributes. |
Organization | IETF | ISO/ITU |
Supporting operations | SNMP,only supports 5 operations. | CMIP consists of 11 operations. |
Security | SNMP uses a community name, which is not even encrypted, SNMP uses polling. | 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) |
