An NMS connected to a 10-Mbps Ethernet LAN is monitoring a network comprising routers, hubs, and workstations. There are 1,000 nodes in the network to monitor. It sends an SNMP query to each station once a minute and receives a response when the stations are up. Assume that an average frame size is 1,000 bytes long for get-request and response messages.
1- What is the maximum traffic load on the LAN that has the NMS?
We assume now that the network comprises ten sub-networks with equally distribution (i.e., 100 nodes for each sub-network), an RMON monitoring each subnet.
2- What is the monitoring load on each subnet?
3- What is the benefit from using RMON in the LAN performance?
---------------------------------
Download and install the latest version of Wireshark program from www.wireshark.org to analyze the network traffic on your computer in live capture.
1- Run the program by starting capture of frame and provide the screenshot of the Wireshark interface with selecting one interface (Ethernet or WiFi).
2- Select one frame among the captured frames and provide the stack of the used protocols.
3- Filter the results for a particular source or destination IP address v4 in your local network and provide the screenshot.
