Question One
1.5 Marks:
Learning Outcome(s):
Describe network management issues, standards and architecture.
Why do we need organizational model in NM? How would you describe manager, agent and managed object in the organizational model?
Answer:
· We need the organizational model to understand the components of a network management system, their functions, and their infrastructure and their relationships which are provided by the organizational mode. The model also defines the terms object, agent, and manager
1. The Manager Sends requests to the agents, Monitors alarms generated by the agents, Houses applications and finally provides user interface that help the network administrator to manage the network.
2. The Agent resides in the managed object, it gathers information from objects, Configures its parameters and Responds to managers’ requests. It also Generates alarms and sends them to mangers
3. The Managed object represent the Network element that is managed, it also houses management agent.
Question Two
1.5 Marks
Learning Outcome(s):
Describe network management issues, standards and architecture.
How would you describe Client/Server Model? Also explain client and server roles to ensure network operation.
Answer
· The client server model has two processes the client and the server where the client process requests a service and the server process provides the required service.
· The client initiates a request to the server and waits for the results.
· The server executes the process to provide the requested service and sends the results to the client.
Question Three
1.5 Marks
Learning Outcome(s):
Recognize conceptual and practical knowledge of different versions of Simple Network Management Protocol (SNMP).
A sniffer tool is used to capture some SNMP messages querying for its UDP group. Compose a data frame (Similar to Figure 5.17) for SNMP PDU types: Get Request from the manager to the agent (noc1 noc2) and Get Response from the agent to the manager (noc2 noc1) based on the followings:
|
Version |
0 |
|
Community |
Public |
|
Request ID |
200 |
|
sysUpTime |
2,000,000 |
|
udplnDatagrams |
50,000 datagrams |
|
udpNoPortS |
5,000 datagrams |
|
udplnErrors |
3000 datagrams |
|
udpOutDatagrams |
25,000 datagrams |
Answer:
13:55:47.445936 noc1.btc.gatech.edu.164 > noc2.btc.gatech.edu.snmp:
Community = public
GetRequest(111)
Request ID = 200
system.sysUpTime.0
udp.udplnDatagrams.0
udp.udpNoPortS.0
udp.udplnErrors.0
udp.udpOutDatagrams.0
Get Request from the manager to the agent (noc1 noc2)
13:55:47.455936 noc2.btc.gatech.edu.snmp > noc1.btc.gatech.edu.164:
Community = public
GetResponse(172)
Request ID = 200
system.sysUpTime.0 = 2000000
udp.udplnDatagrams.0=50000
udp.udpNoPortS.0=5000
udp.udplnErrors.0=3000
udp.udpOutDatagrams.0=25000
Get Response from the agent to the manager (noc2 noc1)
