1 Mark Learning Outcome(s) Describe and evaluate the different SNMP tools, network statistics tools and protocol analyzer for network management Question Three A Local Area Network (LAN) Containing a switch with 8 ports which connects an NMS, a printer, a server, and hosts A, B, C, and D. The LAN is connected to Internet by router R. The following figure shows this LAN MS Printer erve Internet Figure 1 Ports 1 and 7 are down and the rest are up. The NMS can detect that port 1 and port 7 are down using traps or monitoring tools. Explain these two methods. Which method can locate the exact port number?Explanation / Answer
Traps:
SNMP traps are alert messages sent from a remote SNMP-enabled device to a central collector, the "SNMP manager".
A trap might tell you that a device is overheating.
Traps are used when the Device needs to alert the Network Management software of an event without being polled.
Traps ensure that the NMS gets information if an certain event occurs on the device that needs to be recorded without being Polled by the NMS first.
Network monitoring tool:
Network monitoring tool is the networking tool that is used to examine usage of local area network and provide a statistical data of uploads and downloads in a network.
Monitoring tool is usually used to monitor I/P traffic between the LAN and the internet.
It is a network diagnostic system that is used to monitor local area network and provide a statistical display of the same.
The data can be further used to improve the network efficiency.
