Objectives

In this activity, you will complete the following objectives.

• Establish an out-of-band connection.
• Establish an in-band connection.

Note: This activity opens in Physical mode. You will see a representation of the devices in an equipment rack. The PC is on a table next to the rack. You can switch to Simulation mode by clicking the button in the blue bar at the top.

Instructions

Part 1:  Establish an Out-of-Band Connection

Out-of-band connections are typically used for local access to the device. No IP addressing is required. The network technician has physical access to the device and can connect a cable to either the console or USB port between the device and a PC or laptop. The technician can then use terminal emulation software to connect to the command line interface.

In this part, you will use the console ports to connect to a router and a switch. Then you will use the USB port to connect to another router.

Step 1:  Connect the console cable.

1. Using the device selection box, select the Console cable to connect the PC to the console port of the Router.
2. Click the Router. Select Console in the pop-up menu.
3. Locate the PC on the table. You will need to scroll down and to the right of the Rack to locate it.
4. Click the PC. Select RS-232 in the pop-up menu. You should now see a blue console cable connected to the correct port on the Router and the PC.

Step 2:  Access the router.

1. Click PC.
2. Click the Desktop tab. Click Terminal.
3. Review the Terminal Configuration settings. These are the correct console settings for accessing a Cisco device using a console connection. Click OK to access the Router.
4. At this point, there is no output because the router is powered off. Close the Terminal.

Note: With physical equipment, you will not need to reopen the terminal when powering on devices or move the console cable to a different device.

5. To power up the Router, click the Router. Power up the Router. Navigate to the Physical tab. Click the Power switch. Zoom in as necessary to locate the power switch.
6. Connect to the Router again using the Terminal on the PC. You will see the router output. Enter n to skip the initial configuration dialog. Press Enter to start configuration.

7. Close the terminal window when done.
8. Disconnect the console cable from the PC and the router when finished. Click Delete on the toolbar at the top and click one end of the console cable to disconnect the console cable. Click Delete again to de-select the tool.

Step 3:  Access the switch.

You can also connect to the switch for configuration via the console port.

1. Connect a console cable from the Switch to the PC using the same procedure as the previous step.
2. On the PC, navigate to the Terminal. Press Enter to see the prompt.

Step 4:  Access East via a USB console connection.

For some of the newer routers, you can also connect to the router via the USB console port from the USB port on a PC.

1. Using the device selection box, select the USB cable to connect the PC to the USB console port of the router East.
2. Click East. Select USB Console in the pop-up menu.
3. Click the PC. Select USB0 in the pop-up menu.
4. Click the PC. Click the Desktop tab. Click Terminal. Click OK to access the router East.
5. Press Enter a few times to see the output.

Part 2:  Establish an In-Band Connection

In-band connections are established across an existing network connection between the laptop or PC and the device you wish to access. For this type of connection, an IP address is required. However, you do not need to use terminal emulation software. You can simply use the command line on any device that can access to the remote device using IP addressing. In this part, you will access the routers East and West via an in-band connection.

The routers East and West are configured with a local username admin with the password class for SSH access.Use the existing East console connection to establish an in-band connection to the West router.

1. At the prompt of the router East, enter the command ssh -l admin 64.100.1.1. Enter the password class when prompted.

East> ssh -l admin 64.100.1.1

Password:
