Lecture 8: CMIP Summary

Key Concepts

CMIP: OSI protocol for network management
Components: CMIS, ACSE, ROSE, ISO SMI, MIB
Services: Association, Notification, Operation
Objects: Defined by attributes/operations/behavior

Review Questions & Answers

1. How CMIP works?

Answer:
Uses CMIS services through:

ACSE (connection control)
ROSE (remote operations)
CMISE (info exchange)
Manages objects via MIB database.

2. What is CMIS?

Answer:
Common Management Info Service providing:

Association: M-Initialize/Terminate/Abort
Notification: M-Event-Report
Operation: M-Get/Set/Create/Delete

3. Three CMIP services?

Answer:

Association: Setup/end connections
Notification: Event alerts
Operation: Data actions (get/set/create)

4. CMIP structure?

Answer:

ISO SMI: Object definition rules
MIB: Managed objects database
Layers: ACSE/ROSE/CMISE over OSI stack

5. SNMP vs CMIP?

Answer:

Feature	SNMP	CMIP
Family	TCP/IP	OSI
Focus	Simplicity	Flexibility
Security	Basic	ASN.1 encoded

New Questions & Answers

1. When to use CMIP over SNMP?

Answer:
For complex OSI networks needing advanced security and reporting.

2. What does ROSE do?

Answer:
Handles remote operations like executing commands on agents.

3. Key benefit of CMIP?

Answer:
Built-in security with authentication and event logging.

4. How are objects defined?

Answer:
By:

Attributes (properties)
Operations (actions)
Behavior (reactions)

5. Main CMIP drawback?

Answer:
Complexity - harder to implement than SNMP.
