Task 1: Cable the Ethernet Links of the Network

Cable the Ethernet links for a network that is similar to the one in the topology diagram. The output
used in this lab is from Cisco 1841 routers. However, you can use any current router in your lab as
long as it has the required interfaces as shown in the topology. A simple way to identify the available
interfaces on a router is by entering the show ip interface brief command.

Which of the devices in the topology diagram require an Ethernet cable between them?

PC1 to S1, S1 to R1, and R2 to PC2

Connect the R1 router to the S1 switch. Step 1.

Use a straight-through Ethernet cable to connect the FastEthernet 0/0 interface of the R1
router to the FastEthernet 0/1 interface on the S1 switch.

What color is the link status light next to the FastEthernet 0/0 interface on R1? green

What color is the link status light next to the FastEthernet 0/1 interface on S1? green

Connect PC1 to the S1 switch.

Step 2.

Use a straight-through Ethernet cable to connect the NIC of PC1 to the FastEthernet 0/2
interface of the S1 switch.

What color is the link status light next to the NIC interface on PC1? green

What color is the link status light next to the FastEthernet 0/2 interface on S1? green

If the link status lights are not green, wait a few moments for the link between the two
devices to become established. If the lights do not turn green after a few moments, check
that you are using a straight-through Ethernet cable and that the power is on for the S1
switch and PC1.

Connect PC2 to the R2 router. Step 3.

Use a crossover Ethernet cable to connect the FastEthernet 0/0 interface of the R2 router to
the NIC of PC2. Because there is no switch between PC2 and the R2 router, a crossover
cable is required for a direct link between the PC and the router.

What color is the link status light next to the NIC interface on PC2? green

What color is the link status light next to the FastEthernet 0/0 interface on R2? green
