- Configure the computers to use DHCP
- Configure static addressing on the server
- Use ipconfig to retrieve host IP information
- Use ping to verify connectivity
Hint: To ensure that the instructions always remain visible during an activity, click the Top check box in the lower left-hand corner of this instruction window.
In this activity, you will investigate the topology, configure DHCP and static addressing, and use commands to verify addressing and test connectivity.
Step 1: Study the Topology.
The topology shows two PCs, a switch, a server, a router, and a cloud.
- Notice the PCs are connected to BranchSwitch using straight-through cables.
- Notice the green triangles on each side of the straight-through links (next to each PC and next to BranchSwitch). Green triangles on both sides of a link indicate the correct cable type was used to connect those devices.
Note: There should be green triangles at both ends of each cable connection. If you do not see the green triangles navigate to Options > Preferences from Packet Tracer menu and check the Show Link Lights check box.
Step 2: Configure DHCP on the PCs.
- Click PC0.
- In the PC0 window, select the Desktop tab.
- Click IP Configuration and select DHCP to enable the PC to act as a DHCP client. You should see the following message after clicking the DHCP button: DHCP request successful.
- Close the PC0 configuration window by selecting the X in the upper right-hand corner.
- Repeat steps 2a – 2d for PC1.
Step 3: Observe the IP Configuration Information Assigned to Each PC.
- Click PC0. Click the Desktop tab.
- Click Command Prompt. At the PC> prompt, enter the ipconfig /all command. Press the space bar to see all the output.
- Record the IP address, subnet mask, default gateway, and DNS server address information that was dynamically assigned via DHCP to PC0.
- Repeat steps 3a – 3c for PC1.
- Using the ping command, test connectivity between the PCs and the default gateway (BranchOffice FastEthernet 0/0 interface IP address).
1) At the PC0> prompt, enter ping PC1’s IP address.
2) At the PC0> prompt, enter ping default gateway IP address.
3) At the PC1> prompt, enter ping PC0’s IP address.
4) At the PC1> prompt, enter ping default gateway IP address.
Step 4: Switch to Static Addressing.
Despite all the benefits of dynamic addressing schemes such as DHCP, sometimes a static scheme is required. Configure Server0 to use static addressing.
- Click Server0 to open the configuration window.
- Click the Desktop tab. Click IP Configuration.
- Verify that it is using static IP addressing.
Enter the IP information as follows:
IP Address: 172.16.1.100
Subnet Mask: 255.255.255.0
Default Gateway: 172.16.1.254
- Server0 is now configured with a static address. Close IP Configuration.
- Click PC1 to open its configuration window.
- In the command prompt, ping Server0. The pings should be successful.
Check your score. It should be 100%.
