SNMP vs. CMIP By: Kamyar Partovi Ravneet Johal CS 158B SNMP vs. CMIP
Agenda • Introduction • What is SNMP? • What is CMIP? • SNMP vs. CMIP • Conclusion SNMP vs. CMIP
Introduction • Network management is essential for companies. • Exchanging information become more efficient. • Network management needs protocols. • Two important protocols: • Simple Network Management Protocol (SNMP) • Common Management Information Protocol (CMIP) SNMP vs. CMIP
SNMP • Why SNMP ? • SNMP is located in Application layer. • SNMP responsible for exchanging data between network devices. • SNMP has three mechanisms: • Managed devices: Collecting and sorting data. • Agents: Managing data. • Network management system (NMS): Implements the application SNMP vs. CMIP
Advantages and Disadvantages • Advantages: • Easy to use • Expandability • Disadvantages: • Weak security • Too simple! SNMP vs. CMIP
CMIP • Created in 1988 by Internet Activities Board (IAB). • Government and Corporations invested. • Common Management Information Services Element (CMISE). • Information exchange between management stations and management agents. • Remote Operations Service Element (ROSE). • Sends and receives Protocol Data Units (PDUs). SNMP vs. CMIP
CMIP • 11 Data units or operations • M-EventReport • M-EventReport-Confirmed • M-Get • M-Linked-Reply • M-Set • M-Set-Confirmed • M-Action • M-Action-Confirmed • M-Create • M-Delete • M-Cancel-Get SNMP vs. CMIP
SNMP vs. CMIP • Similar operations: SNMP vs. CMIP
SNMP vs. CMIP • What SNMP is to TCP/IP is what CMIP is to OSI. • MIB • More objects in CMIP. • Security • Community name; authorization, access control, and security logs. • Polling • Reporting and polling. SNMP vs. CMIP
SNMP vs. CMIP SNMP vs. CMIP
Conclusion • In our opinion • SNMP and CMIP should not be compared. • LANs and WANs • SNMP better for LANs; CMIP better for WANs • Analogies • High-level programming language and assembly language. • Like two different religions. • Religions should not be compared. • Network Manager acts as God. • Sacrifices (celibacy). • Services (help the poor).
