Working at a Small-to-Medium Business or ISP

d) Select the Config tab. Change the PC Display Name to PC-B. Select the FastEthernet tab on the left and

add the IP address of 192.168.1.2 and subnet mask of 255.255.255.0. Close the PC-B configuration

window.

e) Click on PC2.

f) Select the Config tab. Change the PC Display Name to PC-C. Select the FastEthernet tab on the left and

add the IP address of 192.168.1.3 and subnet mask of 255.255.255.0. Close the PC-C configuration

window.

Step 3: Observe the flow of data from PC-A to PC-C by creating network traffic.

a) Switch to Simulation Mode by selecting the tab that is partially hidden behind the Real Time tab in the

bottom right-hand corner. The tab has the icon of a stopwatch on it.

b) Click the Edit Filter button in the Edit List Filter area. In the event list filter, click on All/None to deselect

every filter. Select just the ARP and ICMP filters.

c) Select a Simple PDU by clicking the closed envelope on the right vertical toolbar. Move your cursor to the

display area of your screen. Click on PC-A to establish the source. Move your cursor to PC-C and click to

establish the destination.

**Notice that two envelopes are now positioned beside PC-A. One envelop is ICMP, while the other is

ARP. The Event List in the Simulation Panel will identify exactly which envelop represents ICMP and

which represents ARP.

d) Select Auto Capture / Play from the Play Controls area of the Simulation Panel. Below the Auto / Capture

button is a horizontal bar, with a vertical button that controls the speed of the simulation. Dragging the

button to the right will speed up the simulation, while dragging is to the left will slow down the simulation.

e) The animation will run until the message no more events appears. All requested events have been

completed. Select OK to close the message box.

f) Choose the Reset Simulation button in the Simulation Panel. Notice that the ARP envelop is no longer

present. This has reset the simulation but has not cleared any configuration changes or dynamic table

entries, such as ARP table entries. The ARP request is not necessary to complete the ping because PC- A already has the MAC address in the ARP table.

g) Choose the Capture / Forward button. The ICMP envelop will moved from the source to the hub and stop.

The Capture / Forward button allows you to move the simulation one step at a time. Continue selecting

the capture/forward button until you complete the event.

h) Choose the Power Cycle Device button on the bottom left, above the device icons.

i) An error message will appear asking you to confirm reset. Choose Yes. Now both the ICMP and ARP

envelops are present again. The Reset Network will clear any configuration changes not saved and will

clear all dynamic table entries, such as the ARP and MAC table entries.

Step 4: View ARP Tables on each PC.

a) Choose the Auto Capture / Play button to repopulate the ARP table on the PCs. Click OK when the

completed message appears.
