9.2.9: Examine the ARP Table #ccnanetworkengineer#ccna#computer#networking#switch#configure#router
Objectives
Part 1: Examine an ARP Request
Part 2: Examine a Switch MAC Address Table
Part 3: Examine the ARP Process in Remote Communications
Background
This activity is optimized for viewing PDUs. The devices are already configured. You will gather PDU information in simulation mode and answer a series of questions about the data you collect.
Instructions
Part 1: Examine an ARP Request
Step 1: Generate ARP requests by pinging 172.16.31.3 from 172.16.31.2.
Open a command prompt
a. Click 172.16.31.2 and open the Command Prompt.
b. Enter the arp -d command to clear the ARP table.
Close a command prompt
c. 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.
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.
