Objectives of the lab

  • Gather PDU Information

  • Reflection Questions

Background

This lab is prepared for viewing PDUs. The devices are already configured. You will get PDU information using simulation mode and answer questions about the data you collect.

Gather PDU Information

Gather PDU information as a packet travels from 192.168.10.2 to 192.168.20.2

Click 172.16.31.2 > click desktop and open the Command Prompt.

Enter the ping 192.168.20.2 command in command prompt.

Switch to simulation mode you will see a PDU appears next to192.168.10.2.

Click the PDU and note the following information from the Outbound PDU Layer tab:

Destination MAC Address: 0060.47AD.C801

Source MAC Address: 000A.41E7.AD04

Source IP Address: 192.168.10.2

Destination IP Address: 192.168.20.2

 At Device: Computer Click Capture / Forward to move the PDU to the next device. Gather the same information from Step just like step gather at 192.168.20.2. Repeat this method until the PDU reaches to its target. Maintain a record of the PDU information in a table.

pdu information

Repeat this procedure for all of the following:

  1. Ping 192.168.20.3 from 192.168.10.3
  2. 2.Ping 192.168.20.4 from 192.168.10.4
  3. Ping 192.168.20.4 from 192.168.10.3
  4. Ping 192.168.10.4 from 192.168.20.3

 Answer the following questions regarding the captured data:

  1. Did the Hub lose any of the information given to it?
  2. What does the Hub do with MAC addresses and IP addresses?
  3. Did the wireless Access Point do anything with the information given to it?
  4. Was any MAC or IP address lost during the wireless transfer?
  5. What was the highest OSI layer that the Hub and Access Point used?
  6. Did the Hub or Access Point ever replicate a PDU that was rejected with a red “X”?
  7. When examining the PDU Details tab, which MAC address appeared first, the source or the destination?
