Enter the arp -d command to clear the ARP table. Enter Simulation mode and enter the command ping 172.16.31.3. Two PDUS will be generated. The ping command cannot complete the ICMP packet without knowing the MAC address of the destination. So the computer sends an ARP broadcast frame to find the MAC address of the destination a. b. c d. Click Capture/Forward once. The ARP PDU moves Switch1 while the ICMP PDU disappears, waiting for the ARP reply. Open the PDU and record the destination MAC address. Is this address listed in the table above? Yes Click Capture/Forward to move the PDU to the next device. How many copies of the PDU did Switch1 make? e 4 What is the IP address of the device that accepted the PDU? f. Open the PDU and examine Layer 2. What happened to the source and destination MAC addresses? g. Click Capture/Forward until the PDU returns to 172.16.31.2. How many copies of the PDU did the switch make during the ARP reply? h. Task 2: Examine the ARP table. Note that the ICMP packet reappearS. Open the PDU and examine the MAC addresses. Do the MAC addresses of the source and destination align with their IP addresses? Switch back to Realtime and the ping completes. a b Click 172.16.31.2 and enter the arp-a command. To what IP address does the MAC address entry correspond? C. Step 4: In general, when does an end device iecue an ARP request? Page 2 of 5 m

Answer 1

Task 1.

f. 172.16.31.3 .This IP address of the device accepted the PDU.

g.

h. 2 PDU copy.

Task 2.

a.The Source and Destination MAC addresses are 000C.85CC.1DA7 >> 0060.7036.2849.switch1 makes 5 PDU copy.Yes the MAC addresses of the source and destination align with their IP addresses.

c. It will show IP address: 172.16.31.3 MAC address: 0060.7036.2849.

step 4. When it doesn’t know the destination MAC address.
